Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method and apparatus. Background Art

[0002] Two communication devices can use a wired transmission medium to achieve data transmission. A wired transmission medium refers to a transmission medium with a physical entity that connects two communication devices, such as twisted pair, coaxial cable, optical fiber, etc. A wired transmission medium can include multiple transmission channels for transmitting data. For example, a twisted pair can include 4 transmission channels (lanes) for transmitting data. In the case where some of the transmission channels included in the transmission medium fail, it may cause the data received by the data receiving party to be inconsistent with the data sent by the data sending party. In this case, a speed reduction method can be adopted to reduce the amount of data transmitted on the transmission channel to ensure that the data received by the data receiving party is the same as the data sent by the data sending party.

[0003] In the above process, speed reduction is used to ensure that the data received by the data receiving party is consistent with the data sent by the data sending party, and the bandwidth utilization rate of the transmission medium is relatively low. Summary of the Invention

[0004] This application provides a communication method and apparatus, which solves the problem of low bandwidth utilization rate of the transmission medium caused by using speed reduction to ensure that the data received by the data receiving party is consistent with the data sent by the data sending party.

[0005] In a first aspect, this application provides a communication method. This communication method is executed by a communication device, and the communication device is connected to a transmission medium. This communication method includes: The communication device detects the working state of each of the M transmission channels included in the transmission medium, and uses the transmission channels with normal working states as a first set of transmission channels and the transmission channels with abnormal working states as a second set of transmission channels. Among them, the first set of transmission channels includes N transmission channels, the second set of transmission channels includes M - N transmission channels, M and N are both positive integers, M≥2, and N≥1. The communication device generates a first type of data stream carrying valid data and a second type of data stream not carrying valid data. The communication device sends the first type of data stream to N transmission channels and sends the second type of data stream to M - N transmission channels.

[0006] The communication device transmits a first type of data stream carrying valid data to the transmission channels with normal working states and transmits a second type of data stream not carrying valid data to the transmission channels with abnormal working states according to the detected working states of the respective transmission channels included in the transmission medium. In this way, in the case where some of the transmission channels included in the transmission medium have abnormal working states, all the transmission channels included in the transmission medium are still all used for data transmission, realizing full throughput transmission of the transmission medium and improving the bandwidth utilization rate of the transmission medium.

[0007] In a possible implementation, when the number of transmission channels with abnormal working states is less than the failure transmission channel threshold number, the communication device obtains a second rate according to M, N, and a first rate. The first rate is used to indicate the maximum data volume that the transmission medium can support for transmission per unit time when the working states of all transmission channels in the transmission medium are normal. The second rate is used to indicate the maximum data volume that the transmission medium can support for transmission per unit time when M - N transmission channels in the transmission medium have abnormal working states. The communication device sends a first type of data stream to N transmission channels and a second type of data stream to M - N transmission channels at the second rate. In this way, it is ensured that when the number of failed transmission channels is less than the failure channel threshold number, full-throughput data transmission is still maintained.

[0008] In another possible implementation, the communication device calculates the ratio of M to N to obtain a first value, and the communication device obtains a second rate according to the product of the first rate and the first value. In this way, the communication device adjusts the maximum data volume that can be supported for transmission per unit time according to the actual working state of the transmission channels, so that the data volume to be transmitted matches the actual working state of the transmission channels.

[0009] In another possible implementation, when the number of transmission channels with abnormal working states is greater than or equal to the failure transmission channel threshold number, the communication device obtains a second quantity according to M, N, and a first quantity. The first quantity is used to indicate the number of data streams sent by the communication device per unit time when the working states of all transmission channels included in the transmission medium are normal. The second quantity is used to indicate the number of data streams sent by the communication device per unit time when M - N transmission channels included in the transmission medium have abnormal working states. The communication device sends a first type of data stream to N transmission channels and a second type of data stream to M - N transmission channels at the second quantity. In this way, it is ensured that when the number of failed transmission channels is greater than or equal to the failure channel threshold number, full-throughput data transmission is still maintained.

[0010] In another possible implementation, the communication device calculates the ratio of N to M to obtain a second value, and the communication device obtains a second quantity according to the second value and the first quantity. In this way, the communication device adjusts the number of data streams sent per unit time according to the actual working state of the transmission channels, so that the number of data streams sent per unit time matches the actual working state of the transmission channels.

[0011] In another possible implementation, the communication device obtains N symbols carrying valid data according to the number of transmission channels included in the first transmission channel set, and obtains M - N symbols not carrying valid data according to the number of transmission channels included in the second transmission channel set. And the communication device generates a first type of data stream using the N symbols carrying valid data, and generates a second type of data stream using the M - N symbols not carrying valid data. In this way, it is ensured that when the number of faulty transmission channels is greater than or equal to the faulty channel number threshold, full-throughput data transmission is still maintained.

[0012] In a second aspect, the present application provides a communication method. This communication method is executed by a communication device, and the communication device is connected to a transmission medium. The communication method includes: The communication device detects the working state of each of the M transmission channels included in the transmission medium, and uses the transmission channels with normal working states as the first transmission channel set, and uses the transmission channels with abnormal working states as the second transmission channel set. Among them, the first transmission channel set includes N transmission channels, the second transmission channel set includes M - N transmission channels, both M and N are positive integers, M ≥ 2, and N ≥ 1. The communication device receives a first type of data stream sent by N transmission channels, and receives a second type of data stream sent by M - N transmission channels. Among them, the first type of data stream carries valid data, and the second type of data stream does not carry valid data. The communication device parses the first type of data stream to obtain the valid data carried by the first type of data stream.

[0013] In a possible implementation, when the number of transmission channels with abnormal working states is less than the faulty transmission channel threshold number, the communication device obtains a second rate according to M, N, and a first rate. Wherein, the first rate is used to indicate: when the working states of all transmission channels in the transmission medium are normal, the maximum amount of data that the transmission medium supports to transmit per unit time. The second rate is used to indicate: when the working states of M - N transmission channels in the transmission medium are abnormal, the maximum amount of data that the transmission medium supports to transmit per unit time. The communication device receives the first type of data stream sent by N transmission channels at the second rate, and receives the second type of data stream sent by M - N transmission channels.

[0014] In another possible implementation, the communication device calculates the ratio of M to N to obtain a first value, and the communication device obtains a second rate according to the product of the first rate multiplied by the first value.

[0015] In another possible implementation, when the number of transmission channels with abnormal working states is greater than or equal to the failure transmission channel threshold number, the communication device obtains a second quantity according to M, N, and a first quantity. The first quantity is used to indicate the number of data streams received by the communication device per unit time when the working states of all the transmission channels included in the transmission medium are normal. The second quantity is used to indicate the number of data streams received by the communication device per unit time when the working states of M - N transmission channels included in the transmission medium are abnormal. The communication device receives the first type of data streams sent by N transmission channels and receives the second type of data streams sent by M - N transmission channels by using the second quantity.

[0016] In another possible implementation, the communication device calculates the ratio of N to M to obtain a second value, and the communication device obtains a second quantity according to the second value and the first quantity.

[0017] In a third aspect, the present application provides a communication method. The communication method is executed by a communication system, and the communication system includes: a first communication device and a second communication device, and the first communication device and the second communication device are connected by a transmission medium. The communication method includes: the first communication device and the second communication device respectively detect the working state of each of the M transmission channels included in the transmission medium, and use the transmission channels with normal working states as a first transmission channel set and use the transmission channels with abnormal working states as a second transmission channel set. The first transmission channel set includes N transmission channels, and the second transmission channel set includes M - N transmission channels, where M and N are both positive integers, M ≥ 2, and N ≥ 1. The first communication device generates a first type of data stream carrying valid data and a second type of data stream not carrying valid data. The first communication device sends the first type of data stream to N transmission channels and sends the second type of data stream to M - N transmission channels. The second communication device receives the first type of data stream sent by N transmission channels and receives the second type of data stream sent by M - N transmission channels. The first type of data stream carries valid data, and the second type of data stream does not carry valid data. The second communication device analyzes the first type of data stream to obtain the valid data carried by the first type of data stream.

[0042] For the sake of clear and concise description of the following embodiments, a brief introduction to the related technologies is given first.

[0043] Figure 1 Schematic diagram of the architecture of a data transmission system provided for this application, as Figure 1 shown, the data transmission system 100 includes a source end 110 and a destination end 130, and a communication system 120 for providing communication services to the source end 110 and the destination end 130.

[0044] The source end 110 may refer to an electronic device that sends data. For example, if the source end 110 is an application server or a storage device storing data, etc., the source end 110 can use the communication system 120 to send data to other devices (such as Figure 1The destination end 130) shown sends data. The data stored at the source end 110 may include, but is not limited to: audio, video, text, or other types of data. When the data sent by the source end 110 is a video, audio, or other multimedia file, the source end 110 may use a streaming transmission method to transmit this data, such as a media stream. Before playing, the destination end 130 does not download the entire streaming media file of the media stream to reduce the latency of playing the streaming media corresponding to the media stream by the destination end 130 and improve the quality of experience (QoE) of the user end.

[0045] The communication system 120 may include multiple communication devices that communicate with each other, such as Figure 1 the communication devices 1 to communication device n shown, where n is a positive integer greater than or equal to 1. The communication devices 1 to communication device n may be connected by a transmission medium. The communication devices may include, but are not limited to: devices with data forwarding functions such as routers and switches. The transmission medium may include, but is not limited to: media with data transmission functions such as twisted pairs, coaxial cables, and optical fibers. For more content about the communication system 120, please refer to the relevant description below Figure 2 and will not be elaborated here.

[0046] The destination end 130 may refer to an electronic device that requests data. For example, if the destination end 130 refers to a terminal, the terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver functions, a personal communicationservice (PCS) phone, a desktop computer, a personal digital assistant (PDA), a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and so on.

[0047] It should be noted that the above source end 110 and destination end 130 are only examples provided in this embodiment and should not be construed as a limitation on this application. This application does not limit the specific forms and quantities of the source end 110 and destination end 130 in the data transmission system 100.

[0048] As described above in conjunction with Figure 1 the data transmission system provided by the present application, the communication system will be further described below in conjunction with Figure 2 Figure Figure 2 FIG. Figure 2 is a schematic structural diagram of a communication system provided by the present application. As shown, the communication system includes communication devices 1 to communication devices n. The communication devices 1 to communication devices n can be connected by transmission media such as twisted pair, coaxial cable, and optical fiber. Hereinafter, taking the connection between communication devices 1 to communication devices n using a twisted pair including 4 pairs of cables as an example, the communication system will be described.

[0049] Each communication device included in the communication system can communicate at rates such as 10 Gigabits Per Second (Gbps / G), 5G, 2.5G, 1G, 100 megabits per second (Mbps / M), 10M, etc. If each communication device included in the communication system is to maintain a communication rate of 1G or higher, all 4 pairs of cables included in the twisted pair need to work properly. In some possible examples, one pair of cables of the twisted pair can also be referred to as a transmission channel of the twisted pair.

[0050] In some possible situations, some transmission channels included in the twisted pair may malfunction and cannot maintain a normal working state (i.e., the working state is abnormal). Figure 3 FIG. Figure 3 is a schematic diagram of an abnormal working state. As shown in (a) of Figure 3 FIG., the twisted pair includes: cable pair one (also known as pairA), cable pair two (also known as pairB), cable pair three (also known as pairC), and cable pair four (also known as pairD). Figure 3 In (a) of Figure 3 FIG., it shows that pairA has a malfunction, and this malfunction can be Figure 3 the impedance being severely discontinuous, open circuit, short circuit, etc. shown in (a) of Figure 3 FIG., or other malfunctions that cause abnormal communication not shown in (a) of Figure 4 FIG. Figure 4As shown in (a), each communication device included in the communication system first communicates at a high rate (such as 10G). In the case of communicating at this rate, it is detected whether the receiving party can successfully receive the data transmitted by the sending party. In the case where the receiving party cannot successfully receive the data transmitted by the sending party, each communication device included in the communication system communicates at a lower rate (such as 5G), and the above steps are repeated until the data transmitted by the sending party is successfully received. The flowchart of the above process can be summarized as Figure 4 the process shown in (b). Figure 4 The method shown determines the communication rate that matches the communication state of the transmission channels included in the twisted pair by gradually reducing the communication rate.

[0051] Although the communication system can adopt Figure 4 the rate reduction method shown to maintain communication in the case where the working state of the twisted pair is abnormal, the rate between each communication device included in the communication system is relatively low, generally 100M or 10M. In the case where a certain transmission channel included in the twisted pair (such as the transmission channel for realizing communication rate negotiation) fails, the communication system cannot maintain communication (link down).

[0052] For the above reasons, the present application provides a communication method. In this method: the first communication device sends a first type of data stream carrying valid data on the transmission channels with normal working states, and sends a second type of data stream not carrying valid data on the transmission channels with abnormal working states. In this way, in the case where some of the transmission channels included in the transmission medium have abnormal working states, all the transmission channels included in the transmission medium are still all used for data transmission, realizing full throughput transmission of the transmission medium and improving the utilization rate of the bandwidth of the transmission medium.

[0053] Figure 5 is a schematic flowchart of a communication method provided by the present application. This method can be implemented by Figure 1 the described communication system. This communication system includes a first communication device and a second communication device, and the first communication device and the second communication device are connected by a transmission medium. Below, taking the transmission medium as a twisted pair as an example, the communication method provided by the present application is described. This communication method includes the following S510 to S550.

[0054] S510, the first communication device detects the working state of each of the M transmission channels included in the transmission medium, and uses the transmission channels with normal working states as the first transmission channel set and the transmission channels with abnormal working states as the second transmission channel set.

[0055] Corresponding to S510, the second communication device executes S510A, specifically: the second communication device detects the working state of each of the M transmission channels included in the transmission medium, and uses the transmission channels with normal working states as the first transmission channel set and the transmission channels with abnormal working states as the second transmission channel set.

[0056] Among them, the first transmission channel set includes N transmission channels, the second transmission channel set includes M - N transmission channels, both M and N are positive integers, M≥2, and N≥1.

[0057] Exemplarily, the first communication device can use a fault diagnosis module to detect the working state of the transmission channels included in the twisted pair. Specifically: the first communication device uses the fault diagnosis module to send test signals to pairA, pairB, pairC, and pairD included in the twisted pair respectively, and detects the test signals on each transmission channel to obtain the working state of each transmission channel, and based on the working state of each transmission channel, obtains the first transmission channel set and the second transmission channel set. The fault diagnosis module can be built into the first communication device, such as the module for fault diagnosis included in the Physical Layer (phy) of the first communication device, or it can be provided by other devices or assembled on the first communication device and can implement fault diagnosis.

[0058] The first transmission channel set and the second transmission channel set can include different numbers of transmission channels. Taking a twisted pair including 4 pairs of cables, namely pairA, pairB, pairC, and pairD, as an example, where pairA corresponds to the A transmission channel (also known as A), pairB corresponds to the B transmission channel (also known as B), pairC corresponds to the C transmission channel (also known as C), and pairD corresponds to the D transmission channel (also known as D).

[0059] Example A, the first transmission channel set can include any three of A, B, C, and D, and the second transmission channel set includes the other one transmission channel of the twisted pair. For example, the first transmission channel set can include A, B, and C, and the second transmission channel set includes D.

[0060] Example B, the first transmission channel set can include any two of A, B, C, and D, and the second transmission channel set includes the other two transmission channels of the twisted pair. For example, the first transmission channel set can include A and B, and the second transmission channel set includes C and D.

[0061] Example C, the first transmission channel set can include any one of A, B, C, and D, and the second transmission channel set includes the other three transmission channels of the twisted pair. For example, the first transmission channel set can include A, and the second transmission channel set includes B, C, and D.

[0062] In a possible scenario, the first communication device may use a combination of 1s and 0s to represent the working states of the respective transmission channels included in the twisted pair cable. For example, the first communication device may use 1 to represent that the working state of the transmission channel is normal, and 0 to represent that the working state of the transmission channel is abnormal. The first communication device may store the working states of the respective transmission channels included in the twisted pair cable at the physical layer. Depending on the number of transmission channels included in the first transmission channel set and the second transmission channel set, the working states of the transmission channels included in the twisted pair cable stored by the first communication device are also different, which will be described separately in the following cases.

[0063] Case 1: The situation where one transmission channel is damaged as described in Example A.

[0064] In this case, the first communication device may store the working states of the respective channels included in the twisted pair cable in the representation shown in Table 1. Among them, "normal" in Table 1 represents that the working state is normal, "abnormal" represents that the working state is abnormal, and "other" represents other transmission channels.

[0065] Table 1

[0066]

[0067] Case 2: The situation where two transmission channels are damaged as described in Example B.

[0068] In this case, the first communication device may store the working states of the respective channels included in the twisted pair cable in the representation shown in Table 2.

[0069] Table 2

[0070]

[0071] Case 3: The situation where three transmission channels are damaged as described in Example C.

[0072] In this case, the first communication device may store the working states of the respective channels in the manner shown in Table 3.

[0073] Table 3

[0074]

[0075] As mentioned above, 1 is used to represent that the working state of the transmission channel is normal. In some possible examples, the first communication device may also use 0 to represent that the working state of the transmission channel is normal, and 1 to represent that the working state of the transmission channel is abnormal. This application does not limit the representation method of the working state. According to the actual application needs, other methods can also be used for representation.

[0076] S520, the first communication device generates a first type of data stream carrying valid data and a second type of data stream not carrying valid data.

[0077] The first communication device can generate the first type of data stream and the second type of data stream in different ways. Two possible implementation manners are given below.

[0078] Manner 1

[0079] The first communication device can use an Adaptive Symbol Distribution Module (ASDM) to generate the first type of data stream and the second type of data stream. Figure 6 This is a schematic diagram of the location of an ASDM provided by this application. As Figure 6 shown, the ASDM can be located within the physical coding sublayer (PCS) of the first communication device, such as between the media-dependent coding (such as PAM16) and the symbol distribution module. The ASDM can include a data buffer, a PAD generation module, and a control module. Among them, the data buffer is used to cache data, and the PAD generation module is used to generate pad symbols. The first communication device can use a corresponding identifier in the message to indicate the use of the ASDM. Figure 7 This is a schematic diagram of identifier carrying provided by this application. As Figure 7 shown, the reserved field (i.e., rsvd) located in the least significant bit is used to indicate the use of the ASDM.

[0080] Taking 10G-BASE-T PHY as an example below, the process of the first communication device using the ASDM to generate the first type of data stream and the second type of data stream is described.

[0081] Figure 8 This is the first schematic diagram of data generation provided by this application. As Figure 8As shown in the figure, the link layer (Medium Access Control, MAC) of the first communication device uses an XGMII interface (Xgmii interface) to send link layer packets to the PCS of the first communication device. The PCS receives the link layer packets sent by the link layer, combines two XGMII data (the single data volume is: 32 bits) into data with a data volume of 64 bits, and adds 1 bit of data or control indication to the 64-bit data to obtain the concatenated data with a data volume of 65 bits. The concatenated data with a data volume of 65 bits forms a data block (block) with a size of 65 bits after scrambling. The PCS uses 25 blocks, 97 zeros (zero), and 1 auxiliary bit to obtain 1723-bit data, and forms a 2048-bit code block using forward error correction (FEC) (such as LDPC(1723, 2048)). The 2048-bit code block forms 512 symbols after medium-dependent encoding (such as PAM16). The symbols generated by the first communication device using valid data are the first type of data stream, otherwise the generated symbols are the second type of data stream. In this application, the symbols included in the first type of data stream are called data symbols, and the symbols included in the second type of data stream are also called pad symbols.

[0082] Method 2

[0083] Figure 9A This is a schematic diagram of the position of an RS provided by this application, as Figure 9A shown, the reconciliation sublayer (RS) is located in the link layer (Medium Access Control, MAC) of the first communication device. Figure 9B This is a schematic diagram of the generation of the second type of data provided by this application, as Figure 9B shown, the first communication device uses the reconciliation sublayer to adjust the effective data bandwidth transmitted to the PCS so that the data symbols to be transmitted on the transmission channel match the normally operating transmission channel. Taking the state of each transmission channel included in the transmission medium as 1100 as an example, when sending data, the RS of the first communication device copies the data block to be sent, and the RS pulls down the MII enable signal at the position of the repeated data block, so that the data to be transmitted on each transmission channel is in the form as Figure 9B shown (D0D1D0D1...). In this case, keeping the main frequency of the PCS unchanged, the effective bandwidth between the RS and the PCS becomes the bandwidth that the physical link can actually transmit, so as to realize the full use of the existing physical bandwidth. When receiving data, the second communication device receives the data block in the same way as the RS of the first communication device, which will not be elaborated here.

[0084] S530, the first communication device sends the first type of data stream to N transmission channels and sends the second type of data stream to M - N transmission channels.

[0085] Corresponding to S530, the second communication device executes S540, specifically: the second communication device receives the first type of data stream sent by N transmission channels and the second type of data stream sent by M - N transmission channels.

[0086] According to the different numbers of transmission channels with abnormal working states, the ways for the first communication device to send data to each transmission channel included in the transmission medium are also different, which are described in different cases below.

[0087] Case 1: The number of transmission channels with abnormal working states is less than the failure transmission channel threshold number.

[0088] In a possible case, the first communication device obtains a second rate according to M, N, and a first rate, and the first communication device uses the second rate to send the first type of data stream to N transmission channels and send the second type of data stream to M - N transmission channels. Among them, the first rate is used to indicate: when the working states of all transmission channels in the transmission medium are normal, the maximum amount of data that the transmission medium can support for transmission per unit time. The second rate is used to indicate: when the working states of M - N transmission channels in the transmission medium are abnormal, the maximum amount of data that the transmission medium can support for transmission per unit time.

[0089] The first communication device can obtain the second rate in the following way, specifically: the first communication device calculates the ratio of M to N to obtain a first value, and obtains the second rate according to the product of the first rate multiplied by the first value. The first communication device can obtain the second rate in various ways, and several possible examples are given below.

[0090] Example 11, the first communication device can obtain the second rate using formula (1).

[0091]

[0092] Among them, v1 is the data transmission rate of each transmission channel when the working states of all M transmission channels are normal, v2 is the data transmission rate of each transmission channel when the working states of N transmission channels are normal, M is the total number of all transmission channels included in the transmission medium, and N is the number of transmission channels with normal working states included in the transmission medium.

[0097]

[0098] Among them, v1 is the data transmission rate of each transmission channel when the working states of all M transmission channels are normal, v2 is the data transmission rate of each transmission channel when the working states of N transmission channels are normal, M is the total number of all transmission channels included in the transmission medium, N is the number of transmission channels with normal working states included in the transmission medium, and a is a constant.

[0099] Example 14, the first communication device can obtain the second rate by using formula (4).

[0100]

[0101] Among them, v1 is the data transmission rate of each transmission channel when the working states of all M transmission channels are normal, v2 is the data transmission rate of each transmission channel when the working states of N transmission channels are normal, M is the total number of all transmission channels included in the transmission medium, N is the number of transmission channels with normal working states included in the transmission medium, and a and c are constants.

[0102] Taking the first communication device obtaining the second rate by using Example 11, the number of faulty transmission channel thresholds being 2, and 1 transmission channel being faulty as an example, the process of the first communication device transmitting the first type of data stream and the second type of data stream is described.

[0103] The first communication device compares the number of faulty transmission channels (i.e., 1) with the number of faulty transmission channel thresholds (i.e., 2), and obtains that the number of faulty transmission channels is less than the number of faulty transmission channel thresholds. In this case, Figure 10 This is the first data transmission schematic diagram provided by this application, as Figure 10As shown, based on the operating status of each transmission channel (such as 1101) obtained by the ASDM of the first communication device, data symbols are sent to the 3 transmission channels (i.e., transmission channel A, transmission channel B, and transmission channel D) included in the first transmission channel set at a rate of (4 / 3)*v1, and pad symbols are sent to 1 transmission channel (i.e., transmission channel C). The ASDM uses a data buffer and control logic to add pad symbols. The ASDM writes data symbols (the first type of data stream) into the data buffer at the in-channel clock frequency (frequency, F), and the ASDM reads the data symbols in the data buffer at a second frequency (4 / 3*F). When the counter counts to 1, 2, and 4, the read enable transmits data symbols to transmission channel A, transmission channel B, and transmission channel D, and when the counter counts to 3, pad symbols are transmitted to transmission channel C.

[0104] In the above process, in the case where transmission channel C is damaged, the data symbols in the data buffer are read at the second frequency (4 / 3*F), so that the baud rate of the data on transmission channel A, transmission channel B, and transmission channel D is 4 / 3 times the baud rate on each transmission channel when no fault occurs in each transmission channel. In this way, it is ensured that when the number of faulty transmission channels is less than the fault channel number threshold, full-throughput data transmission is still maintained.

[0105] Corresponding to the first communication device sending data symbols on the transmission channels with normal operating status and pad symbols on the transmission channels with abnormal operating status. The second communication device receives data symbols from the transmission channels with normal operating status and discards the pad symbols received on the transmission channels with abnormal operating status. Please continue to refer to Figure 10 , the second communication device can use ASDM to receive data on the transmission medium. The ASDM uses a FIFO and control logic to receive data symbols from transmission channel A, transmission channel B, and transmission channel D when the counter counts to 1, 2, and 4, and discards the pad symbols transmitted by transmission channel C when the counter counts to 3. It is realized that when the number of faulty transmission channels is less than the fault channel number threshold, the throughput remains unchanged.

[0106] Case 2: The number of transmission channels with abnormal operating status is greater than or equal to the fault transmission channel threshold number.

[0107] In this case, according to whether the first communication device adjusts its in-channel clock frequency (i.e., the number of data streams sent per unit time, also known as the first quantity), there are also various different processing methods. Two possible examples are given below.

[0108] Example A: The first communication device adjusts the frequency of the clock on the same channel.

[0109] In the first possible scenario, the first communication device obtains a second quantity based on M, N, and the first quantity, and transmits the first type of data stream to N transmission channels using the second quantity, and transmits the second type of data stream to M - N transmission channels using the second quantity. Here, the first quantity is used to indicate the number of data streams transmitted by the communication device per unit time when all the transmission channels included in the transmission medium are in normal working states. The second quantity is used to indicate the number of data streams transmitted by the communication device per unit time when M - N transmission channels included in the transmission medium are in abnormal working states.

[0110] The first communication device can obtain the second quantity in the following manner. Specifically, the first communication device calculates the ratio of M to N to obtain a second value, and obtains the second quantity based on the product of the first rate and the second value. The first communication device can obtain the second quantity in various ways. Several possible examples are given below.

[0111] Example 21: The first communication device can obtain the second quantity using formula (5).

[0112]

[0113] Here, m1 is the number of data streams transmitted by the communication device per unit time when all M transmission channels are in normal working states. m2 is the number of data streams transmitted by the communication device per unit time when N transmission channels are in normal working states. M is the total number of transmission channels included in the transmission medium, and N is the number of transmission channels with normal working states included in the transmission medium.

[0114] Example 22: The first communication device can obtain the second quantity using formula (6).

[0115]

[0116] Here, m1 is the number of data streams transmitted by the communication device per unit time when all M transmission channels are in normal working states. m2 is the number of data streams transmitted by the communication device per unit time when N transmission channels are in normal working states. M is the total number of transmission channels included in the transmission medium, N is the number of transmission channels with normal working states included in the transmission medium, and c is a constant.

[0117] Example 23: The first communication device can obtain the second quantity using formula (7).

[0118]

[0119] Among them, m1 is the number of data streams sent by the communication device per unit time when the working states of all M transmission channels are normal. m2 is the number of data streams sent by the communication device per unit time when the working states of N transmission channels are normal. M is the total number of all transmission channels included in the transmission medium, N is the number of transmission channels with normal working states included in the transmission medium, and a is a constant.

[0120] Example 24, the first communication device can use formula (8) to obtain the second quantity.

[0121]

[0122] Among them, m1 is the number of data streams sent by the communication device per unit time when the working states of all M transmission channels are normal. m2 is the number of data streams sent by the communication device per unit time when the working states of N transmission channels are normal. M is the total number of all transmission channels included in the transmission medium, N is the number of transmission channels with normal working states included in the transmission medium, and a and c are constants.

[0123] Taking the first communication device obtaining the second quantity by using Example 21, the number of faulty transmission channel thresholds being 2, and there being 2 faulty transmission channels as an example, the process of the first communication device transmitting the first type of data stream and the second type of data stream is described.

[0124] The first communication device compares the number of faulty transmission channels (i.e., 2) with the number of faulty transmission channel thresholds (i.e., 2), and obtains that the number of faulty transmission channels is equal to the number of faulty transmission channel thresholds. In this case, the first communication device uses the Adaptive Clock Management Block (ACMB) to adjust the number of data streams sent by the first communication device per unit time (i.e., the first quantity) according to the working states of each transmission channel (such as 1001) obtained by the fault diagnosis module, and obtains the second quantity.

[0125] The process of the first communication device adjusting the first quantity to the second quantity is described as follows: The first communication device can adjust Figure 11 the value of M / N / C in it, change the first quantity to obtain the second quantity that matches the bandwidth of the normally working transmission channels. Figure 11A schematic diagram for adjusting the number of data streams sent per unit time provided by this application. ACMB takes the working status of each transmission channel (i.e., 1001) obtained by the fault diagnosis module as the input to adjust the frequency adjustment coefficient (M / N / C), thereby generating a clock frequency (i.e., the second quantity) that matches the actual bandwidth. For example, in the case of faults in transmission channels B and C, ACMB adjusts the follow - on clock frequency of the first communication device to 2 / 4 of the case where each transmission channel is working properly. In this case, the throughput of the PCS of the first communication device becomes 2 / 4 of the throughput of the PCS when each transmission channel is working properly. Regarding the adjustment process of the value of M / N / C, please refer to the general technology and will not be elaborated here. ACMB can be integrated inside the PHY chip or exist independently. Considering clock SI and chip integration, usually, ACMB is integrated in the PHY chip. As Figure 12 shown, Figure 12 A schematic diagram of the positional relationship between ACMB and ASDM provided by this application.

[0126] Figure 13 The second data transmission schematic diagram provided by this application. As Figure 13 shown, the ASDM of the first communication device sends data symbols to the 2 transmission channels (i.e., transmission channels A and D) included in the first transmission channel set and sends pad symbols to the 2 transmission channels (i.e., transmission channels B and C) according to the working status of each transmission channel (such as 1001) obtained by the fault diagnosis module. ASDM uses a data buffer and control logic to add pad symbols. When the counter counts to 1 and 4, the read enable transmits data symbols to transmission channels A and D, and when the counter counts to 2 and 3, it transmits pad symbols to transmission channels B and C.

[0127] Figure 14 A schematic diagram of data sending and receiving provided by this application. As Figure 14 shown in (a) below, when sending, the ASDM of the first communication device writes data symbols (the first type of data stream) into the data buffer according to the second quantity (2 / 4*F). And ASDM reads the data symbols in the data buffer using the first quantity (F). Specifically, the control module uses a counter with a count of 4 to read the data symbols when the counter counts to 1 or 4 and inserts pad symbols when it counts to 2 or 3. Finally, data in the form of "data symbol - pad symbol - pad symbol - data symbol" is formed, and the distribution module sends this form of data to all transmission channels included in the transmission medium. Corresponding to the data sending process of the first communication device, the second communication device receives data from the transmission channel. AsFigure 14 As shown in (b), during reception, the ASDM of the second communication device discards the pad symbols received from the transmission channels with abnormal working states, and writes the data symbols received from the transmission channels with normal working states into the data buffer. The ASDM reads data symbols from the data buffer using a second quantity (2 / 4*F). Thus, full-throughput transmission of the transmission medium (i.e., "data symbol - pad symbol - pad symbol - data symbol") is achieved in the case of two faulty transmission channels.

[0128] Example B: The first communication device does not adjust the frequency of the clock on the line.

[0129] The first communication device obtains N symbols carrying valid data according to the number of transmission channels included in the first set of transmission channels, and obtains M - N symbols not carrying valid data according to the number of transmission channels included in the second set of transmission channels. The first communication device generates a first type of data stream using the N symbols carrying valid data, and generates a second type of data stream using the M - N symbols not carrying valid data.

[0130] Exemplarily, the RS receiving side of the first communication device replicates the data symbols. And the RS sending side of the first communication device, according to the status of each transmission channel obtained by the fault diagnosis module (such as 1100), when corresponding data is transmitted to transmission channel A, transmission channel B, and transmission channel C, enables the MII signal to obtain the data symbols transmitted to transmission channel A, transmission channel B, and transmission channel C, and when corresponding data is transmitted to transmission channel D, pulls down the MII signal to obtain the pad symbols transmitted to transmission channel D. Keeping the main frequency of the PCS unchanged, the data transmitted from the MAC layer of the first communication device to the PHY layer matches the status of each transmission channel, so that the effective bandwidth between the RS and the PCS becomes the bandwidth that the transmission medium can actually transmit (i.e., the transmission channels with normal working states), thus making full use of the existing physical bandwidth.

[0131] After S540, the second communication device can also execute S550, specifically: the second communication device parses the first type of data stream to obtain the valid data carried by the first type of data stream.

[0132] The above uses a twisted pair with 4 cable pairs as the transmission medium and takes the number of faulty transmission channel thresholds as 1 as an example to illustrate the communication method provided in this application. In some possible cases, the transmission medium can also be coaxial cable, optical fiber, etc., and the number of faulty transmission channel thresholds can also be other quantities, which are not limited in this application.

[0133] Figure 15A flowchart provided for this application, as Figure 15 shown, the communication device diagnoses faults in the transmission channel, uses an adaptive symbol distribution module to distribute data to the transmission channel, and detects the accuracy of the data transmitted through the transmission channel. In this way, when some of the transmission channels included in the transmission medium are in an abnormal working state, all the transmission channels included in the transmission medium are still all used for data transmission, achieving full throughput transmission of the transmission medium and improving the utilization rate of the bandwidth of the transmission medium.

[0134] Corresponding to S530, the first communication device detects the working state of each of the M transmission channels included in the transmission medium, determines the first set of transmission channels with normal working states, and the second set of transmission channels with abnormal working states. The second communication device receives the first type of data stream sent by N transmission channels, and receives the second type of data stream sent by M - N transmission channels. Among them, the first type of data stream carries valid data, and the second type of data stream does not carry valid data. The second communication device parses the first type of data stream to obtain the valid data carried by the first type of data stream.

[0135] The above describes the communication method provided by this application by taking the first communication device as an example of sending the first type of data stream carrying valid data to the transmission channels with normal working states and sending the second type of data stream not carrying valid data to the transmission channels with abnormal working states. In some possible examples, the first communication device can also close the transmission channels with abnormal working states and send the first type of data stream carrying valid data to the transmission channels with normal working states. For example, the first communication device can use the Physical Medium Dependent Sublayer (PMA) to implement the function of sending the first type of data stream carrying valid data to the transmission channels with normal working states. In this way, the power consumption of the first communication device can be reduced. In some other possible examples, the second communication device can also close the transmission channels with abnormal working states and receive the first type of data stream carrying valid data transmitted by the transmission channels with normal working states. For example, the second communication device can use the Physical Medium Dependent Sublayer (PMA) to implement the function of receiving the first type of data stream carrying valid data transmitted by the transmission channels with normal working states. In this way, the power consumption of the second communication device can be reduced. According to the actual application needs, only one of the first communication device and the second communication device can close the transmission channels with abnormal working states, or both can close the transmission channels with abnormal working states. This application does not limit this.

[0136] This application also provides a communication device, Figure 16 which is a schematic structural diagram of a communication device provided for this application, and this communication device can implement Figure 5The functions of the first communication device or the second communication device.

The first quantity is used to indicate: the number of data streams sent by the communication device per unit time when the working states of all transmission channels included in the transmission medium are normal.

The transceiver module 1630 is specifically configured to: send the first type of data stream to the N transmission channels at the second quantity, and send the second type of data stream to the M - N transmission channels at the second quantity.
