Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and in particular, to a data statistics method and device. BACKGROUND

[0002] A data stream can be transmitted in a network. In some scenarios, after receiving the data stream, a receiving end can perform statistics on related parameters of the data stream, so as to perform data processing based on the statistical parameters subsequently. For example, the statistical parameters are used to evaluate the communication quality provided by a transmission channel, or the statistical parameters are used to determine whether the data processing operation of the receiving end device is abnormal, and the like. As a specific example, in a scenario where a sending end performs forward error correction (FEC) encoding on a sent data stream, the receiving end can decode the FEC codewords included in the received data stream, and perform statistics on related parameters based on the decoding result.

[0003] How to perform statistics on the related parameters of the data stream is a problem to be solved at present. SUMMARY

[0004] In the first aspect, the present application provides a data statistics method, which can be applied to a receiving end device. In the embodiments of the present application, considering that the number of bits of a codeword that are corrected can reflect the communication quality provided by a transmission channel and whether the data processing operation of the receiving end device is abnormal, therefore, in the present application, P counters are set in the receiving end device, P can be an integer greater than or equal to 3, and the P counters can respectively perform statistics on the number of codewords with different numbers of corrected bits in a data stream according to the number of bits of the codewords in the data stream that are corrected. Correspondingly, after receiving the data stream, the receiving end device can use the P counters to respectively record the number of codewords with different numbers of corrected bits in the data stream, so as to perform data processing based on the statistical parameters subsequently.

[0005] In a possible implementation, considering that the number of codewords with different numbers of corrected bits in the data stream can reflect whether burst errors occur in the data stream, therefore, after using the P counters to respectively record the number of codewords with different numbers of corrected bits in the data stream, burst errors can be further detected based on the values respectively recorded by the P counters. The detection of burst errors mentioned here can be detection of whether burst errors occur in the data stream, can be detection of the number of times that burst errors occur in the data stream, can be detection of the corresponding data length when burst errors occur in the data stream, and the like.

[0006] In a possible implementation, the number of codewords with different number of corrected bits in the data stream can reflect the error rate of the data stream transmission, and therefore, after the P counters record the number of codewords with different number of corrected bits in the data stream respectively, the error rate can be further calculated based on the values recorded by the P counters respectively.

[0007] In a possible implementation, the error rate includes, but is not limited to, one or more of a codeword error ratio (CER), a bit error ratio (BER), a symbol error ratio (SER), and a frame loss ratio (FLR). In other words, after the P counters record the number of codewords with different number of corrected bits in the data stream respectively, one or more of the CER, the BER, the SER, and the FLR can be further calculated based on the values recorded by the P counters respectively.

[0008] In a possible implementation, the number of codewords with different number of corrected bits in the data stream can reflect whether the synchronization processing of the data stream by the receiving end device is erroneous, and therefore, after the P counters record the number of codewords with different number of corrected bits in the data stream respectively, whether the data stream is erroneous in synchronization can be further detected based on the values recorded by the P counters respectively.

[0009] In a possible implementation, the number of corrected bits corresponding to any two of the P counters is different. As a specific example, the number of corrected bits corresponding to the P counters is continuous, for example, 0 to P-2 and more than P-2 respectively. In this way, the distribution of the number of corrected bits of the codewords included in the data stream can be determined.

[0010] In a possible implementation, after the receiving end device receives the data stream, at least one codeword can be obtained based on the data stream. Further, error correction is performed on each of the at least one codeword to determine the number of corrected bits in each codeword, so as to update the value of at least one of the aforementioned P counters. As a specific example, for any one codeword, after the number of corrected bits in the codeword is determined, the counter corresponding to the number of bits is incremented by 1.

[0011] In a possible implementation, the receiving end device is provided with R counters, which are used to record the number of code word groups with different number of corrected bits in the at least one code word group according to the number of corrected bits in each code word group. R can be a positive integer greater than or equal to 3.

[0012] In a possible implementation, any two of the R counters correspond to different number of corrected bits. As a specific example, the R counters correspond to consecutive number of corrected bits, for example, 0 to R-2 and more than R-2. In this way, the distribution of the number of corrected bits in the code word groups included in the at least one code word group can be determined.

[0013] In a possible implementation, after receiving the data stream, the receiving end device can obtain the at least one code word group based on the data stream. Further, for each code word group, the error correction of each code word included in the code word group is performed to determine the number of corrected bits in each code word, and the number of corrected bits in each code word in the code word group is further summed to obtain the number of corrected bits in the code word group, so as to update the value of at least one of the aforementioned R counters. As a specific example, for any code word group, after determining the number of corrected bits in the code word group, the counter corresponding to the number of corrected bits is incremented by 1.

[0014] In a possible implementation, the receiving end device can be further provided with at least one of a code word group number counter, a code word number counter and a bit number counter. The code word group number counter is used to record the total number of code word groups included in the data stream. The code word number counter is used to record the total number of code words included in the data stream. The bit number counter is used to record the total number of bits included in the data stream. Optionally, the receiving end device can perform one or more of detecting burst error, calculating error rate and detecting synchronization error of the data stream by combining the values recorded by at least one of the code word group number counter, the code word number counter and the bit number counter, and the number of code word groups with different number of corrected bits in the at least one code word group.

[0015] In the second aspect, the present application provides a data statistics method, which can be applied to a receiving device. The receiving device can receive a data stream, and further obtain at least one codeword group based on the data stream, and for each codeword group in the at least one codeword group, it includes Q codewords obtained by deinterleaving, where Q is an integer greater than or equal to 2. Taking into account the number of corrected bits in the codeword group, it can reflect the communication quality provided by the transmission channel and whether the data processing operation of the receiving device is abnormal. Therefore, in an embodiment of the present application, the receiving device can count the number of codeword groups with different numbers of bits corrected in the at least one codeword group, so as to facilitate subsequent data processing based on statistical parameters.

[0016] In one possible implementation, considering that the number of codeword groups with different numbers of bits corrected in the at least one codeword group can reflect whether burst errors have occurred in the data stream, after counting the number of codeword groups with different numbers of bits corrected in the at least one codeword group, burst errors can be further detected based on the statistical results. The burst error detection mentioned herein can include detecting whether burst errors have occurred in the data stream, detecting the number of burst errors occurring in the data stream, detecting the data length corresponding to the occurrence of burst errors in the data stream, and so on.

[0017] In one possible implementation, considering that the number of codeword groups with different numbers of bits corrected in the at least one codeword group can reflect the error rate of data stream transmission, therefore, after counting the number of codeword groups with different numbers of bits corrected in the at least one codeword group, the error rate of data stream transmission can be further calculated based on the statistical results.

[0018] In one possible implementation, the error rate includes, but is not limited to, one or more of CER, BER, SER, and FLR. In other words, using the solution of the present application, after counting the number of codeword groups with different numbers of corrected bits in the at least one codeword group, one or more of CER, BER, SER, and FLR for data stream transmission can be further calculated based on the statistical results.

[0019] In one possible implementation, considering the number of codeword groups with different numbers of bits corrected in the at least one codeword group, it can be reflected whether an error occurs in the synchronization processing of the data stream by the receiving device. Therefore, after counting the number of codeword groups with different numbers of bits corrected in the at least one codeword group, it is possible to further detect whether the data stream has a synchronization error based on the statistical results.

[0020] In a possible implementation, the above first aspect and any one of the first aspect, and the above second aspect and any one of the second aspect can be combined in any manner without conflict.

[0022] In a third aspect, the present application provides a data statistical method, which can be applied to a receiving end device. In the embodiments of the present application, the number of code words with corrected symbols can reflect the communication quality provided by a transmission channel and whether the data processing operation of the receiving end device is abnormal, and therefore, in the present application, P counters are set in the receiving end device, P can be an integer greater than or equal to 3, and the P counters can respectively count the number of code words with different numbers of corrected symbols in a data stream according to the number of code words with corrected symbols in the data stream. Correspondingly, after the receiving end device receives the data stream, the P counters can be used to respectively record the number of code words with different numbers of corrected symbols in the data stream, so as to facilitate subsequent data processing based on the statistical parameters.

[0023] In a possible implementation, the number of code words with different numbers of corrected symbols in the data stream can reflect whether burst errors occur in the data stream, and therefore, after the P counters respectively record the number of code words with different numbers of corrected symbols in the data stream, burst errors can be further detected based on the number recorded by the P counters. The detection of burst errors mentioned here can be detection of whether burst errors occur in the data stream, can be detection of the number of times of burst errors occurring in the data stream, or can be detection of the corresponding data length when burst errors occur in the data stream, and the like.

[0024] In a possible implementation, the number of code words with different numbers of corrected symbols in the data stream can reflect the error rate of the data stream transmission, and therefore, after the P counters respectively record the number of code words with different numbers of corrected symbols in the data stream, the error rate can be further calculated based on the number recorded by the P counters.

[0025] In a possible implementation, the error rate includes but is not limited to one or more of CER, BER, SER, and FLR. In other words, after the P counters respectively record the number of code words with different numbers of corrected symbols in the data stream, one or more of CER, BER, SER, and FLR can be calculated based on the number recorded by the P counters.

[0026] In a possible implementation, the number of codewords with different number of corrected symbols in the data stream is considered to reflect whether the synchronization processing of the data stream by the receiving end device is correct or not, and therefore, after the P counters are used to record the number of codewords with different number of corrected symbols in the data stream respectively, the synchronization error of the data stream can be detected based on the number recorded by the P counters respectively.

[0027] In a possible implementation, the number of corrected symbols corresponding to any two of the P counters is different. As a specific example, the number of corrected symbols corresponding to the P counters is continuous, for example, 0 to P-2 and more than P-2 respectively. In this way, the distribution of the number of corrected symbols of the codewords included in the data stream can be determined.

[0028] In a possible implementation, after the receiving end device receives the data stream, at least one codeword can be obtained based on the data stream. Further, each codeword in the at least one codeword is corrected to determine the number of corrected symbols in each codeword, so as to update the value of at least one of the P counters. As a specific example, for any one codeword, after the number of corrected symbols in the codeword is determined, the counter corresponding to the number of corrected symbols is incremented by 1.

[0029] In a possible implementation, the receiving end device is provided with R counters, which are used to record the number of codeword groups with different number of corrected symbols in the at least one codeword group according to the number of corrected symbols in each codeword group in the at least one codeword group. R can be a positive integer greater than or equal to 3.

[0030] In a possible implementation, the number of corrected symbols corresponding to any two of the R counters is different. As a specific example, the number of corrected symbols corresponding to the R counters is continuous, for example, 0 to R-2 and more than R-2 respectively. In this way, the distribution of the number of corrected symbols of the codeword groups included in the at least one codeword group can be determined.

[0031] In a possible implementation, after receiving the data stream, the receiving end device can obtain at least one code word group based on the data stream. Further, for each code word group, error correction is performed on each code word included in the code word group to determine the number of corrected symbols in each code word, and further, the number of corrected symbols in each code word in the code word group is summed to obtain the number of corrected symbols in the code word group, so as to update the value of at least one of the aforementioned R counters. As a specific example, for any code word group, after determining the number of corrected symbols in the code word group, the counter corresponding to the number of symbols is incremented by 1.

[0032] In a possible implementation, the receiving end device can further be provided with at least one of a code word group number counter, a code word number counter, and a symbol number counter.

The number of corrected symbols in a code word group can reflect the communication quality provided by a transmission channel, and whether the data processing operation of the receiving end device is abnormal. Therefore, in the embodiments of the present application, the receiving end device can count the number of code word groups with different numbers of corrected symbols in the at least one code word group, so as to perform subsequent data processing based on the counted parameters.

[0034] In a possible implementation, the number of code word groups in the at least one code word group that have different numbers of corrected symbols can reflect whether the data stream has a burst error, and therefore, after the number of code word groups in the at least one code word group that have different numbers of corrected symbols is counted, a burst error of the data stream can be detected based on the counting result.

[0114] An embodiment of the present application provides a data statistical method and device, which can statistically analyze relevant parameters based on a received data stream.

[0115] Before introducing the data statistical method provided by an embodiment of the present application, the possible application scenarios of the present application are introduced first.

[0116] Referring to FIG. 3, Figure 1 FIG. 3 is a schematic diagram of an exemplary application scenario provided by an embodiment of the present application.

[0117] As shown in FIG. 4, Figure 1 the chip or optical module of the sending end can perform FEC encoding on the data stream to be sent, wherein, Figure 1 FIG. 4 shows that the sending end can perform FEC encoding on the data stream to be sent in parallel by using an 8-way FEC encoder, the 8-way FEC codewords obtained through FEC encoding are subjected to 8:1 bit pair interleaving, and the data stream obtained through 8:1 bit pair interleaving is subjected to a pad insertion operation. Figure 1 As shown in FIG. 5,

[0118] After the receiving end receives the data stream sent by the sending end, the data stream can be processed, and the processing process of the data stream by the receiving end is the inverse process of the processing process of the data stream by the sending end. Specifically, the chip or optical module of the receiving end can first decode the received data stream based on PAM4 symbols, further, for the data stream after decoding, the pad in the data stream is deleted, the data stream obtained by deleting the pad is subjected to 1:8 bit pair deinterleaving, and the 8-way FEC decoder is used to respectively perform FEC decoding on the FEC codewords corresponding to the deinterleaved data stream.

[0119] In one example, the transmitting end can also perform 8:1 bit pair interleaving on the 8-way FEC codeword obtained by FEC encoding based on dual polarization 16-state quadrature amplitude modulation (DP-16QAM) symbols. In this scenario, after performing the pad insertion operation on the data stream, the transmitting end can further perform DP-16QAM encoding on the data stream to which the pad is inserted, and transmit the data stream after the DP-16QAM encoding to the receiving end through the channel. Correspondingly, the chip or optical module of the receiving end can first perform DP-16QAM decoding on the received data stream, further delete the pad in the decoded data stream, perform 1:8 bit pair deinterleaving on the data stream after the pad is deleted, and use the 8-way FEC decoder to perform FEC decoding on the FEC codeword corresponding to each of the deinterleaved data streams.

[0120] In one example, Figure 1 The receiving end and the transmitting end shown can be a server, a network device, a network card, or a single board with specific functions. The network device mentioned herein includes but is not limited to a router or a switch.

[0121] In another example, Figure 1 The receiving end and the transmitting end shown can be different modules (such as different chips) in the same server or network device.

[0122] Figure 1 The chip shown in the above can include but is not limited to a network processor (NP) or an application specific integrated circuit (ASIC).

[0123] In one example, burst error is one of the indicators for evaluating the communication quality provided by the transmission channel. The burst error occurs in multiple places in a short length of data. With the increase of the communication transmission rate, the influence of the burst error on the reliability of the transmission system is also increasing. As a specific example, the burst error can reduce the reliability of the transmission system and make the transmission system more prone to failure. Therefore, to ensure the reliability of the transmission system, the detection of the burst error is particularly important. For example, after detecting the burst error, corresponding processing measures can be taken to enable the data to be normally transmitted through the transmission system. In one example, the data statistical method provided by the embodiments of the present application can perform statistics on related parameters based on the received data stream, and detect the burst error based on the statistical parameters.

[0124] In yet another example, the error rate of the data stream transmitted in the transmission channel is one of the indicators for evaluating the communication quality provided by the transmission channel. The error rate includes, but is not limited to, one or more of CER, BER, SER, and FLR. In one example, the data statistical method provided by the embodiments of the present application can be used to statistically analyze the relevant parameters based on the received data stream, and determine the error rate of the data stream transmitted in the transmission channel based on the statistical parameters.

[0125] In another example, the receiving end needs to synchronize the data stream before deinterleaving the received data stream. If the data stream synchronization error occurs, it will cause abnormal results of the subsequent operations of the receiving end device, such as deinterleaving and FEC decoding. In one example, the data statistical method provided by the embodiments of the present application can be used to statistically analyze the relevant parameters based on the received data stream, and determine whether the data stream synchronization error occurs based on the statistical parameters. If the synchronization error is found, the error information needs to be reported in time.

[0126] Next, the data statistical method provided by the embodiments of the present application will be introduced in combination with the accompanying drawings.

[0127] Referring to Figure 2 , the figure is a flowchart of a data statistical method provided by the embodiments of the present application. Figure 2 The method shown can be applied to a receiving end device. The receiving end device mentioned in the embodiments of the present application can correspond to Figure 1 The receiving end shown can be a chip or an optical module in the receiving end, or can be the receiving end itself, that is, the receiving end device can also be a network device or a server. The server mentioned here can be a server in a data center for storing data and performing related calculations. In addition, the receiving end device can also be a network card.

[0128] Figure 2 The method shown includes the following S101-S102.

[0129] S101: receiving a data stream.

[0130] The receiving end device can receive the data stream sent by the sending end, and the data stream includes one or more bits. In one example, the data stream can be obtained by interleaving the FEC code word obtained by encoding the multi-path FEC encoder and encoding the multi-path FEC encoder. In one example, the FEC code word obtained by encoding the multi-path FEC encoder can be interleaved based on the PAM4 symbol.

[0131] S102: P counters respectively record the number of code words in the data stream that are corrected by different numbers of bits or symbols, and P is greater than or equal to 3.

[0132] In the embodiment of the present application, the receiving end device is provided with P counters, which are used to record the number of code words with different number of corrected bits or symbols in the data stream according to the number of corrected bits or symbols of each code word included in the data stream. The code word mentioned in the embodiment of the present application can be an FEC code word, and the two can be used alternately. The FEC code word can be an FEC outer code word, and in the case of concatenated code, the FEC code word can also be an FEC inner code word. In an example, the counter can also be understood as a register.

[0133] In an example, the code word in the embodiment of the present application can be a BCH code, for example, BCH (126, 110) code or BCH (128, 120) code. In another example, the code word in the embodiment of the present application can be a Hamming code or a systematic binary (128, 120) code obtained by Hamming encoding.

[0134] In the embodiment of the present application, if the P counters are used to record the number of code words with different number of corrected bits in the data stream respectively, the number of corrected bits corresponding to any two counters in the P counters is different.

[0135] In a specific example, the number of corrected bits corresponding to the P counters is continuous, for example, 0 to P-2 and more than P-2 respectively. For example:

[0136] When P is equal to 3, the number of corrected bits corresponding to the three counters can be 0, 1 and more than 1 respectively.

[0137] When P is equal to 4, the number of corrected bits corresponding to the four counters can be 0, 1, 2 and more than 2 respectively.

[0138] When P is equal to 5, the number of corrected bits corresponding to the five counters can be 0, 1, 2, 3 and more than 3 respectively.

[0139] And so on.

[0140] The more than 3 mentioned this time refers to greater than 3.

[0141] The embodiment of the present application does not specifically limit the specific value of P, and P can be greater than or equal to 3.

[0142] In one example, the value of P can be determined according to the maximum error correction capability of the receiving end device, wherein the maximum error correction capability of the receiving end device refers to the maximum number of bits that can be corrected by the receiving end device for a code word to be corrected, in other words, when the number of bits with errors in a code word is greater than the maximum error correction capability of the receiving end device, the receiving end device cannot correct the code word. In one specific example, the value of P can be the maximum error correction capability of the receiving end device + 2. In this scenario, the code word whose number of corrected bits exceeds P-2 is actually a code word that cannot be corrected.

[0143] In yet another specific example, the number of corrected bits corresponding to the aforementioned P counters can also be discontinuous, for example, when P equals 3, the number of corrected bits corresponding to the three counters can be 0, 1, and 3, respectively.

[0144] In one example, after the receiving end device receives the data stream, the data stream can be synchronized, and then the synchronized data stream can be de-interleaved, for example, based on PAM4 symbols, to obtain a plurality of code words. Further, each code word in the plurality of code words can be subjected to FEC correction to determine the number of corrected bits in each code word, thereby updating the value of at least one of the aforementioned P counters. As a specific example, for any code word, after determining the number of corrected bits in the code word, the counter corresponding to the number of bits can be incremented by 1. For example:

[0145] P equals 5, and the P counters are P0, P1, P2, P3, and P3+, respectively. P0 is used to record the number of code words with 0 corrected bits, P1 is used to record the number of code words with 1 corrected bit, P2 is used to record the number of code words with 2 corrected bits, P3 is used to record the number of code words with 3 corrected bits, and P3+ is used to record the number of code words with more than 3 corrected bits. For code word 1 in the data stream, after FEC correction, it is determined that code word 1 has 2 corrected bits, and then the counter P2 is incremented by 1.

[0146] In the embodiments of the present application, if the P counters are used to record the number of code words with different numbers of corrected symbols in the data stream, respectively, then any two counters in the P counters correspond to different numbers of corrected symbols.

[0147] In one specific example, the number of corrected symbols corresponding to the P counters is continuous, for example, 0 to P-2, and more than P-2, respectively. For example:

[0148] When P equals 3, the number of corrected symbols corresponding to the three counters can be 0, 1, and more than 1, respectively.

[0149] When P equals 4, the number of corrected symbols corresponding to the 4 counters can be: 0, 1, 2, and more than 2.

[0150] When P equals 5, the number of corrected symbols corresponding to the 5 counters can be: 0, 1, 2, 3, and more than 3.

[0151] And so on.

[0152] The more than 3 mentioned above refers to greater than 3.

[0153] The embodiment of the present application does not specifically limit the specific value of P, and P can be greater than or equal to 3.

[0154] In an example, the value of P can be determined according to the maximum error correction capability of the receiving end device, wherein the maximum error correction capability of the receiving end device refers to the maximum number of symbols that can be corrected by the receiving end device for a code word to be corrected, in other words, when the number of error symbols in a code word is greater than the maximum error correction capability of the receiving end device, the receiving end device cannot correct the code word. In a specific example, the value of P can be the maximum error correction capability of the receiving end device + 2. In this scenario, the code word with the number of corrected symbols greater than P-2 is actually an uncorrectable code word. The maximum number of symbols that can be corrected by the receiving end device can be equal to the maximum number of bits that can be corrected by the receiving end device.

[0155] In another specific example, the number of corrected symbols corresponding to the P counters can also be discontinuous, for example, when P equals 3, the number of corrected symbols corresponding to the 3 counters can be: 0, 1, and 3.

[0156] In an example, after the receiving end device receives the data stream, the data stream can be synchronized, and then the data stream after synchronization can be deinterleaved, for example, based on PAM4 symbols to obtain a plurality of code words. Further, each code word in the plurality of code words is subjected to FEC error correction to determine the number of corrected symbols in each code word, thereby updating the value of at least one of the P counters. As a specific example, for any code word, after determining the number of corrected symbols in the code word, the counter corresponding to the number of symbols can be incremented by 1. For example:

[0157] P equals to 5, and the P counters are P0, P1, P2, P3, and P3+ respectively. P0 is used to record the number of code words with 0 corrected symbols, P1 is used to record the number of code words with 1 corrected symbol, P2 is used to record the number of code words with 2 corrected symbols, P3 is used to record the number of code words with 3 corrected symbols, and P3+ is used to record the number of code words with more than 3 corrected symbols. For a code word 1 in the data stream, it is determined by FEC correction that the code word 1 is corrected by 2 symbols, and then the counter P2 is increased by 1.

[0158] As an example, for any code word, the code word can be decoded by using an FEC decoder, the FEC decoder decodes the code word and corrects the code word, and accordingly, based on the decoding of the code word by the FEC decoder, the number of corrected bits or the number of corrected symbols in the code word can be determined.

[0159] Taking the determination of the number of corrected bits in the code word as an example, it can be understood with reference to Figure 3 Figure 3 A schematic diagram of a data processing process provided by an embodiment of the present application. As shown in Figure 3 After the receiving end device receives the data stream, it can first perform deinterleaving decoding based on PAM4 symbols, further synchronize the data stream after decoding, then delete the pad in the data stream after synchronization, and perform 1:8 bit pair deinterleaving on the data stream after deleting the pad. One deinterleaving can obtain 8 FEC code words, which correspond to Figure 3 FEC code word 0 to FEC code word 7 as shown. In addition, the receiving end device includes 8 FEC decoders for decoding the 8 FEC code words obtained by one deinterleaving. In other words, after one deinterleaving obtains 8 FEC code words, the 8 FEC code words are FEC decoded by using the 8 FEC decoders FEC decoder 0 to FEC decoder 7 respectively, so as to obtain the number of corrected bits in each of the 8 FEC code words FEC code word 0 to FEC code word 7.

[0160] In an example, after using P counters to record the number of code words with different numbers of corrected bits in the data stream respectively, the burst error can be further detected based on the values recorded by the P counters respectively. The detection of the burst error mentioned here can be the detection of whether the burst error occurs in the data stream, the detection of the number of times of the burst error occurring in the data stream, the detection of the corresponding data length when the burst error occurs in the data stream, etc. How to use the number recorded by the P counters respectively to detect the burst error is not limited in the embodiments of the present application.

[0161] ​In yet another example, after the P counters respectively record the number of codewords in the data stream that are corrected by different number of bits, the error rate can be further calculated based on the values respectively recorded by the P counters. For the error rate, reference can be made to the description of the error rate above, which will not be repeated here. For how to calculate the error rate by using the number respectively recorded by the P counters, the embodiments of the present application are not limited in particular.

[0162] In another example, after the P counters respectively record the number of codewords in the data stream that are corrected by different number of bits, the error rate can be further calculated based on the values respectively recorded by the P counters. For the error rate, reference can be made to the description of the error rate above, which will not be repeated here. For how to calculate the error rate by using the number respectively recorded by the P counters, the embodiments of the present application are not limited in particular.

[0163] In one example, after the P counters respectively record the number of codewords in the data stream that are corrected by different number of bits, the error rate can be further calculated based on the values respectively recorded by the P counters. For the error rate, reference can be made to the description of the error rate above, which will not be repeated here. For how to calculate the error rate by using the number respectively recorded by the P counters, the embodiments of the present application are not limited in particular.

[0164] In yet another example, after the P counters respectively record the number of codewords in the data stream that are corrected by different number of bits, the error rate can be further calculated based on the values respectively recorded by the P counters. For the error rate, reference can be made to the description of the error rate above, which will not be repeated here. For how to calculate the error rate by using the number respectively recorded by the P counters, the embodiments of the present application are not limited in particular.

[0165] In another example, after the P counters respectively record the number of codewords in the data stream that are corrected by different number of bits, the error rate can be further calculated based on the values respectively recorded by the P counters. For the error rate, reference can be made to the description of the error rate above, which will not be repeated here. For how to calculate the error rate by using the number respectively recorded by the P counters, the embodiments of the present application are not limited in particular.

[0166] As can be seen from the above description, the embodiment of the present application provides a new data statistics method. The receiving end device can use P counters to record the number of codewords with different numbers of corrected bits or symbols in the data stream. Optionally, the values recorded by the P counters can be analyzed subsequently to determine the communication quality provided by the transmission channel (for example, to detect burst errors or calculate the error rate). Alternatively, the values recorded by the P counters can be analyzed subsequently to determine whether the data processing operation (for example, the data stream synchronization operation) of the receiving end device is abnormal.

[0167] The embodiment of the present application also provides another data statistics method. Next, the data statistics method will be introduced in combination with the accompanying drawings.

[0168] Referring to Figure 4 The figure is a flowchart of another data statistics method provided by the embodiment of the present application. Figure 4 The method shown can be applied to a receiving end device. The description of the receiving end device can refer to the description in the foregoing description section, which will not be repeated here.

[0169] Figure 4 The method shown includes the following S201-S203.

[0170] S201: receiving a data stream.

[0171] The receiving end device can receive the data stream sent by the sending end, and the data stream includes one or more bits. In an example, the data stream can be obtained by interleaving the FEC codeword encoded by the multi-path FEC encoder. In an example, the FEC codeword encoded by the multi-path FEC encoder can be interleaved based on PAM4 symbols.

[0172] S202: obtaining at least one codeword group from the data stream, each codeword group in the at least one codeword group including Q codewords obtained by deinterleaving, Q being greater than or equal to 2.

[0173] In an example, after the receiving end device receives the data stream, the receiving end device can perform PAM4 decoding, pad deletion, and data stream synchronization operation on the data stream in sequence, and then deinterleaves the data stream after synchronization to obtain a plurality of codewords. For example, the receiving end device can deinterleave the data stream after synchronization based on PAM4 symbols to obtain a plurality of codewords. Further, the at least one codeword group is obtained based on the plurality of codewords. For each codeword group in the at least one codeword group, the codeword group includes Q codewords obtained by deinterleaving one or more times, and Q is an integer greater than or equal to 2. For example, in an example, the receiving end device can deinterleave the data stream after synchronization based on PAM4 symbols to obtain a plurality of codewords, and then obtain the at least one codeword group based on the plurality of codewords. Figure 1In the illustrated scenario, one deinterleaving can obtain 8 FEC codewords, and when a codeword group includes Q codewords obtained by one deinterleaving, the value of Q can be 2, 3, 4, 5, 6, 7, or 8. For example, when the value of Q is equal to 8, the 8 FEC codewords obtained by one deinterleaving constitute a codeword group. When a codeword group includes Q codewords obtained by multiple deinterleavings, the value of Q can be greater than 8, for example. The codeword mentioned in the embodiments of the present application can be an FEC codeword, and the two terms can be used interchangeably. The FEC codeword can be an FEC outer code codeword, and in the scenario of a concatenated code, the FEC codeword can also be an FEC inner code codeword.

[0174] S203: Count the number of codeword groups in which different numbers of bits or symbols are corrected in the at least one codeword group.

[0175] In one example, after obtaining the at least one codeword group, for any one codeword group, error correction (for example, FEC error correction) can be performed on each codeword in the codeword group to determine the number of bits corrected for each codeword. Further, in one example, the number of bits corrected for each codeword group can be summed to obtain the number of bits corrected for the codeword group. For example, a codeword group includes 8 codewords, and each of the 8 codewords is corrected by 1 bit, so the number of bits corrected for the codeword group is 8. In yet another example, the number of symbols corrected for each codeword group can be summed to obtain the number of symbols corrected for the codeword group. For example, a codeword group includes 8 codewords, and each of the 8 codewords is corrected by 1 symbol, so the number of symbols corrected for the codeword group is 8.

[0176] In one example, the receiving end device is provided with R counters. As one example, the R counters are used to record the number of codeword groups in which different numbers of bits are corrected in the at least one codeword group according to the number of bits corrected for each codeword group in the at least one codeword group. As another example, the R counters are used to record the number of codeword groups in which different numbers of symbols are corrected in the at least one codeword group according to the number of symbols corrected for each codeword group in the at least one codeword group. R can be a positive integer greater than or equal to 3.

[0177] In the case where the R counters are used to record the number of codeword groups in which different numbers of bits are corrected in the at least one codeword group, any two counters of the R counters correspond to different numbers of bits corrected.

[0178] In one specific example, the numbers of bits corrected corresponding to the R counters are consecutive, for example, 0 to R-2, and more than R-2, respectively. For example:

[0179] When R equals 3, the 3 counters respectively correspond to the number of corrected bits which can be: 0, 1 and more than 1;

[0180] When R equals 4, the 4 counters respectively correspond to the number of corrected bits which can be: 0, 1, 2 and more than 2;

[0181] When R equals 5, the 5 counters respectively correspond to the number of corrected bits which can be: 0, 1, 2, 3 and more than 3;

[0182] And so on.

[0183] The embodiment of the present application does not specifically limit the specific value of R, and R can be greater than or equal to 3.

[0184] In one example, the value of R can be determined according to the maximum error correction capability of the receiving end device and the number Q of codewords included in one codeword group. In one specific example, the value of R can be the product of the maximum error correction capability of the receiving end device and Q plus 2. For example, the value of Q is 8, the maximum error correction capability of the receiving end device is 3 bits, and the value of R can be 26. In this scenario, the codeword group in which the number of corrected bits is more than R-2 is actually a codeword group in which all the Q included codewords cannot be corrected.

[0185] The maximum error correction capability of the receiving end device can be referred to the relevant description above, which is not repeated here.

[0186] In yet another specific example, the number of corrected bits corresponding to the aforementioned R counters can also be discontinuous. For example, R equals 3, and the 3 counters respectively correspond to the number of corrected bits which can be: 0, 8, 16.

[0187] In the scenario of recording the number of codeword groups in which different numbers of bits are corrected in the at least one codeword group by using R counters, for any one codeword group, after determining the number of corrected bits in the codeword group, the counter corresponding to the number of bits can be added by 1. For example:

[0188] R equals 26, and the R counters are R0, R1, R2, R3, …, R24 and R24+. R0 is used to record the number of codeword groups in which 0 bits are corrected, R1 is used to record the number of codeword groups in which 1 bit is corrected, R2 is used to record the number of codeword groups in which 2 bits are corrected, R3 is used to record the number of codeword groups in which 3 bits are corrected, and so on, R24 is used to record the number of codeword groups in which 24 bits are corrected, and R24+ is used to record the number of codeword groups in which more than 24 bits are corrected. For codeword group 1 in the at least one codeword group, after error correction, it is determined that 8 bits in the codeword group 1 are corrected, and then the counter R8 is added by 1.

[0189] In the case that the R counters are used to record the number of code word groups in the at least one code word group that have different number of corrected symbols, any two counters of the R counters correspond to different number of corrected symbols.

[0190] In one specific example, the number of corrected symbols corresponding to the R counters are consecutive, for example, 0 to R-2, and more than R-2, respectively. For example:

[0191] When R equals 3, the number of corrected symbols corresponding to the 3 counters can be 0, 1, and more than 1, respectively.

[0192] When R equals 4, the number of corrected symbols corresponding to the 4 counters can be 0, 1, 2, and more than 2, respectively.

[0193] When R equals 5, the number of corrected symbols corresponding to the 5 counters can be 0, 1, 2, 3, and more than 3, respectively.

[0194] And so on.

[0195] The embodiments of the present application do not specifically limit the specific value of R, and R can be greater than or equal to 3.

[0196] In one example, the value of R can be determined according to the maximum error correction capability of the receiving end device and the number Q of code words included in a code word group. In one specific example, the value of R can be the product of the maximum error correction capability of the receiving end device and Q plus 2. For example, the value of Q is 8, the maximum error correction capability of the receiving end device is 3 symbols, and the value of R can be 26. In this scenario, the code word group with the number of corrected symbols more than R-2 is actually a code word group in which all the Q code words included therein cannot be corrected.

[0197] The maximum error correction capability of the receiving end device can refer to the related description above, which is not repeated here.

[0198] In yet another specific example, the number of corrected symbols corresponding to the aforementioned R counters can also be discontinuous. For example, R equals 3, and the number of corrected symbols corresponding to the 3 counters can be 0, 8, and 16, respectively.

[0199] In the scenario of recording the number of code word groups in the at least one code word group that have different number of corrected symbols by using R counters, for any code word group, after determining the number of corrected symbols in the code word group, the counter corresponding to the number of corrected symbols can be incremented by 1. For example:

[0200] R is equal to 26, and the R counters are R0, R1, R2, R3, ..., R24, and R24+. R0 is used to record the number of codeword groups corrected by 0 symbols, R1 is used to record the number of codeword groups corrected by 1 symbol, R2 is used to record the number of codeword groups corrected by 2 symbols, R3 is used to record the number of codeword groups corrected by 3 symbols, and so on. R24 is used to record the number of codeword groups corrected by 24 symbols, and R24+ is used to record the number of codeword groups corrected by more than 24 symbols. For codeword group 1 in the at least one codeword group, if error correction determines that codeword group 1 has been corrected by 8 symbols, then counter R8 is incremented by 1.

[0201] As an example, for any codeword, the codeword can be decoded using an FEC decoder. When the FEC decoder decodes the codeword, it will perform FEC error correction on the codeword. Accordingly, based on the decoding of the codeword by the FEC decoder, the number of corrected bits or symbols in the codeword can be determined.

[0202] For example, to determine the number of corrected bits in a codeword, refer to Figure 5 To understand, Figure 5 This is a schematic diagram of a data processing flow provided in an embodiment of the present application. Figure 5 As shown, after receiving the data stream, the receiving end device can first perform deinterleaving decoding based on the PAM4 symbol, further synchronize the decoded data stream, and then delete the pad in the synchronized data stream, and perform 1:8 bit deinterleaving on the data stream obtained by deleting the pad. One deinterleaving can obtain 8 FEC codewords, corresponding to Figure 5 FEC codeword 0 to FEC codeword 7 are shown. In one example, the eight FEC codewords FEC codeword 0 to FEC codeword 7 can constitute a codeword group. Furthermore, each codeword in the codeword group can be error corrected separately. Specifically, the receiving end device includes eight FEC decoders for decoding the eight FEC codewords obtained by one deinterleaving. When the FEC decoders decode the FEC codewords, they perform error correction on the FEC codewords. In other words, after one deinterleaving obtains eight FEC codewords, the eight FEC decoders FEC decoder 0 to FEC decoder 7 are used to perform FEC decoding on FEC codeword 0 to FEC codeword 7, respectively. The number of corrected bits for each of the eight FEC codewords FEC codeword 0 to FEC codeword 7 can be obtained. Correspondingly, the number of corrected bits for each of the eight FEC codewords FEC codeword 0 to FEC codeword 7 can be summed to obtain the number of corrected bits for the codeword group.

[0203] In an embodiment of the present application, the method for counting the number of codeword groups in which different numbers of bits or symbols are corrected in the at least one codeword group is not limited to the aforementioned R counters. Any method that can perform quantity statistics can be used to count the number of codeword groups in which different numbers of bits or symbols are corrected in the at least one codeword group, and they are not listed one by one here.

[0204] In a specific example, the receiving end device may further be provided with at least one of a codeword group quantity counter, a codeword quantity counter, and a bit quantity counter.

[0205] The codeword group quantity counter is used to record the total number of codeword groups included in the data stream. In one example, the receiving device increases the codeword group quantity counter by 1 each time it obtains a codeword group based on the deinterleaved codeword.

[0206] The codeword quantity counter is used to record the total number of codewords included in the data stream. In one example, when the receiving end device deinterleaves K codewords, the codeword quantity counter is incremented by K. The value of K can be a positive integer, for example, Figure 1 In the scenario shown, the value of K is 8. In one example, the value of the codeword quantity counter may be the product of the value of the codeword group quantity counter and the number Q of codewords included in each codeword group.

[0207] The bit quantity counter is used to record the total number of bits included in the data stream. In one example, the receiving device may increment the bit quantity counter by 1 each time a bit is received. In one example, the value of the bit quantity counter may be the product of the value of the codeword quantity counter and the number of bits included in each codeword.

[0208] In one example, after counting the number of codeword groups with different numbers of bits corrected in the at least one codeword group, burst errors can be detected based on the statistical results. As a specific example, after using R counters to respectively record the number of codeword groups with different numbers of bits corrected in the at least one codeword group, burst errors can be further detected based on the values ​​respectively recorded by the R counters. The detection of burst errors mentioned here can be detecting whether a burst error has occurred in the data stream, or detecting the number of burst errors occurring in the data stream, or detecting the data length corresponding to the burst error occurring in the data stream, etc. The embodiments of the present application do not specifically limit how to detect burst errors using the numbers respectively recorded by the R counters.

[0209] In the case that the receiving end device is further provided with at least one of the code word group number counter, the code word number counter and the bit number counter, the receiving end device can detect the burst error in combination with the values recorded by the at least one of the code word group number counter, the code word number counter and the bit number counter, and the values recorded by the R counters respectively.

[0210] In another example, after counting the number of code word groups in the at least one code word group in which different numbers of bits are corrected, the error rate can be calculated according to the counting result. As a specific example, after the R counters record the number of code word groups in the at least one code word group in which different numbers of bits are corrected respectively, the error rate can be further calculated based on the values recorded by the R counters respectively. For the error rate, reference can be made to the foregoing description of the error rate, which will not be repeated here. For how to calculate the error rate by using the numbers recorded by the R counters respectively, the embodiments of the present application are not specifically limited.

[0211] In the case that the receiving end device is further provided with at least one of the code word group number counter, the code word number counter and the bit number counter, the receiving end device can calculate the error rate in combination with the values recorded by the at least one of the code word group number counter, the code word number counter and the bit number counter, and the values recorded by the R counters respectively.

[0212] In another example, after counting the number of code word groups in the at least one code word group in which different numbers of bits are corrected, the error rate can be calculated according to the counting result. As a specific example, after the R counters record the number of code word groups in the at least one code word group in which different numbers of bits are corrected respectively, the error rate can be further calculated based on the values recorded by the R counters respectively. For the error rate, reference can be made to the foregoing description of the error rate, which will not be repeated here. For how to calculate the error rate by using the numbers recorded by the R counters respectively, the embodiments of the present application are not specifically limited.

[0213] In the case that the receiving end device is further provided with at least one of the code word group number counter, the code word number counter and the bit number counter, the receiving end device can detect the burst error in combination with the values recorded by the at least one of the code word group number counter, the code word number counter and the bit number counter, and the values recorded by the R counters respectively.

[0214] In one example, after counting the number of code word groups with different number of corrected symbols in the at least one code word group, the burst error can be detected according to the counting result. As a specific example, after using the R counters to record the number of code word groups with different number of corrected symbols in the at least one code word group respectively, the burst error can be further detected based on the values recorded by the R counters respectively. The detection of the burst error mentioned herein can be the detection of whether the burst error occurs in the data stream, the detection of the number of times of the burst error occurring in the data stream, the detection of the data length corresponding to the burst error occurring in the data stream, etc. The application embodiments do not make specific limitation on how to use the number recorded by the R counters respectively to detect the burst error.

[0215] In the case that the receiving end device is further provided with at least one of the code word group number counter, the code word number counter and the symbol number counter, the receiving end device can detect the burst error in combination with the values recorded by the at least one of the code word group number counter, the code word number counter and the symbol number counter, and the values recorded by the R counters respectively.

[0216] In another example, after counting the number of code word groups with different number of corrected symbols in the at least one code word group, the error rate can be calculated according to the counting result. As a specific example, after using the R counters to record the number of code word groups with different number of corrected symbols in the at least one code word group respectively, the error rate can be further calculated based on the values recorded by the R counters respectively. The error rate can be referred to the description of the error rate in the foregoing description part, which will not be repeated herein. The application embodiments do not make specific limitation on how to use the number recorded by the R counters respectively to calculate the error rate.

[0217] In the case that the receiving end device is further provided with at least one of the code word group number counter, the code word number counter and the symbol number counter, the receiving end device can calculate the error rate in combination with the values recorded by the at least one of the code word group number counter, the code word number counter and the symbol number counter, and the values recorded by the R counters respectively.

[0218] In another example, after counting the number of code word groups with different number of corrected symbols in the at least one code word group, the receiving end device can detect whether the data stream is in synchronization error according to the counting result. As a specific example, after using the R counters to record the number of code word groups with different number of corrected symbols in the at least one code word group respectively, the receiving end device can further detect whether the data stream is in synchronization error based on the values recorded by the R counters respectively. For the data stream synchronization, refer to the foregoing description, which will not be repeated here. For how to use the number recorded by the R counters to detect whether the data stream is in synchronization error, the embodiments of the present application are not limited in particular.

[0219] In the case that the receiving end device is further provided with at least one of the code word group number counter, the code word number counter and the symbol number counter, the receiving end device can detect whether the data stream is in synchronization error in combination with the values recorded by the at least one of the code word group number counter, the code word number counter and the symbol number counter, and the values recorded by the R counters respectively.

[0220] As can be seen from the foregoing description, the embodiments of the present application provide a new data counting method, and the receiving end device can use the R counters to record the number of code word groups with different number of corrected bits or symbols in the at least one code word group respectively. Optionally, the values recorded by the R counters can be analyzed subsequently to determine the communication quality provided by the transmission channel (for example, to detect burst error or to calculate error rate). Alternatively, the values recorded by the R counters can be analyzed subsequently to determine whether the data processing operation (for example, data stream synchronization operation) of the receiving end device is abnormal.

[0221] In one example, for the receiving end device, at least one of the R counters of the foregoing P counters can be provided, and optionally, at least one of the code word group number counter, the code word number counter and the bit number counter can also be provided. Correspondingly, the receiving end device can use the values recorded by the counters provided by itself to perform one or more of the following operations: detecting burst error, calculating error rate, and detecting whether the data stream is in synchronization error.
