According to an aspect of an embodiment of the present application, a new frame for carrying service data is defined in an OTN system. For small bandwidth services (e.g., services with a data transmission rate in the range of 10 Megabits per second (Mbps) to 10 Gigabits per second (Gbps)), the overhead frequency in the frame structure is increased by increasing the frame overhead or shortening the frame length. Since the overhead frequency in the frame structure is related to the protection switching time in the OTN system, the protection switching time in the OTN system can be shortened, and as a result, the processing efficiency of service data can be improved, i.e., the transmission efficiency of service data can be improved.

[0048] In addition, according to a data processing method, an apparatus, an associated device, and a storage medium according to embodiments of the present application, a transmitting device maps a fourth service into a fourth frame, and the overhead of the fourth frame includes first information, the first information being for one-way delay measurement, and the first information includes at least a first timestamp, which indicates the time when the first information is arranged in the fourth frame.

[0051] The present application will be described in further detail below in conjunction with the drawings and examples.

[0052] In the related art, a conventional OTN network (i.e., an OTN system) introduces an optical service unit (OSU) mechanism to carry small granularity (i.e., small bandwidth) of 10 Mbps to 10 Gbps, and this mechanism may also be referred to as a Sub-1G or fgOTN (fine grain OTN) mechanism. In this case, the mapping mechanism of the OTN system is as shown in FIG. 1. After a service (i.e., service data) is transmitted to an OTN device supporting the OSU mechanism, the OTN device first maps the service into an OSU frame (or a Sub-1G frame, or a fine grain ODU (fgODU) frame, or a fine grain ODU flexible (fgODUflex) frame), encapsulates the OSU frame (or an fgODUflex frame, or an fgODU frame) into an optical payload unit (OPU) frame, encapsulates the OPU frame into an optical channel data unit (ODU) frame, and then encapsulates the ODU frame into an optical transform unit (OTU) frame. Among them, when an OTN device encapsulates an OSU frame (or an fgODUflex frame, or an fgODU frame) into an OPU frame, it may first map the OSU frame (or an fgODUflex frame, or an fgODU frame) into an Optical Service Tributary Unit (OSTU) frame (or a fine grain Optical Data Tributary Unit, fgODTU) frame, and then multiplex the OSTU frame (or an fgODTU frame) into the OPU frame.

[0053] However, if the OSU frame (i.e., Sub-1G frame) adopts the conventional OTN frame structure of 4*3824 as shown in FIG. 2, the following problems may occur. Problem 1 is that only columns 1 to 16 are overhead of the OSU frame, and the frequency of occurrence of the overhead (which can be understood as the repetition frequency of the overhead) does not meet the protection switching time performance in the OTN system. In other words, the performance of the protection switching time is insufficient due to the insufficient frequency of occurrence of the overhead in the OSU frame. Problem 2 is that there is only one FAS included in the overhead of the OSU frame, and the number of FASs cannot meet the alignment needs of the OSU frame. In other words, the OSU frame alignment is slow due to the insufficient number of FASs. Problem 3 is that there is only one MFAS included in the overhead of the OSU frame, and the number of MFAS cannot meet the multi-frame alignment needs of the OSU frame. Problem 4: The overhead of the OSU frame only has one bit for the delay measurement (DM) function. When measuring delay, the source side (i.e., the sending side) inverts this DM bit from 0 to 1 and then sends it to the sink side (i.e., the receiving side). The sink side then returns this DM information (i.e., the DM bit) to the source side. After the source side receives the DM information, it calculates the number of frame periods between the sending and receiving of this DM information and multiplies it by the frame frequency to obtain the round-trip delay result (i.e., the delay measurement result). However, because the transmission time of each frame changes dynamically, the accuracy of this delay measurement method is limited.

[0054] As can be seen from the above description, the OTN frame structure in the related art may not be able to meet the data processing needs of low-bandwidth services. In other words, due to the performance needs of the OSU mechanism (i.e., Sub-1G), the OSU frame (i.e., Sub-1G frame) requires a new frame structure and / or frame overhead.

[0055] Based on this, in order to address the above problem 1, the embodiments of the present application define a new OSU frame (i.e., Sub-1G frame) for carrying service data in the OTN system. For small bandwidth services (e.g., services with a data transmission rate in the range of 10 Mbps to 10 Gbps), the overhead frequency in the frame structure of the OSU frame is increased or the frame length is shortened. Since the overhead frequency in the frame structure is related to the protection switching time of the OTN system, the protection switching time of the OTN system can be shortened, and as a result, the processing efficiency of service data can be improved, i.e., the transmission efficiency of service data can be improved.

[0056] With respect to problem 2 above, in each embodiment of the present application, at least one FAS is included in each row in the frame structure of an OSU frame (i.e., a Sub-1G frame), thereby realizing an increase in the number of FASs in the OSU frame structure, and as a result, the alignment speed of the OSU frame can be improved.

[0057] To address problem 3 above, in each embodiment of the present application, at least one MFAS is included in each row in the frame structure of an OSU frame (i.e., a Sub-1G frame), thereby increasing the number of MFASs in the OSU frame structure and thereby improving the multi-frame alignment speed of the OSU frame.

[0058] To address problem 4 above, in the embodiments of the present application, new DM information including a timestamp is defined for one-way delay measurement (1DM) in an OTN system, so that one-way delay measurement can be subsequently realized based on the timestamp, thereby improving the accuracy of one-way delay measurement.

[0059] To address problem 4 above, in the embodiments of the present application, new DM information including a timestamp is defined for two-way delay measurement (2DM) in an OTN system, so that two-way delay measurement can be subsequently realized based on the timestamp, thereby improving the accuracy of the two-way delay measurement.

[0060] It should be noted that in each embodiment of the present application, the services (first service, second service, third service, fourth service, and fifth service) may be the same service or different services. These services may include small bandwidth services, for example, services with data transmission rates in the range of 10 Mbps to 10 Gbps. These service types may include constant bit rate (CBR) services, for example, synchronous transmission mode (STM)-N services, and the STM-N services may include STM-1, STM-4, STM-16, STM-64, and the like. Alternatively, these service types may include variable bit rate (VBR) services, for example, packet services. Furthermore, the processing related to these services may be understood as processing related to service data.

[0061] In each embodiment of the present application, the frames (first frame, second frame, third frame, fourth frame, fifth frame, and sixth frame) carrying service data may be the same frame or different frames. These frames may be understood as containers for carrying service data, and these frames may be called containers, OSU frames, OSU containers, Sub-1G frames, Sub-1G containers, etc. However, the embodiments of the present application are not limited to the names of these frames as long as their functions are realized.

[0062] In the embodiments of the present application, when the transmitting device and the receiving device transmit each frame (first frame, second frame, third frame, fourth frame, fifth frame, sixth frame), they may first encapsulate these frames into an OSTU frame via a predetermined intermediate step, then encapsulate the OSTU frame into an OPU frame and / or an ODU frame, and then transmit the OPU frame and / or the ODU frame, where the OPU frame may include an OPUflex frame, an OPU0 frame, an OPU1 frame, an OPU2 frame, an OPU3 frame, an OPU4 frame, etc.

[0063] In each embodiment of the present application, the transmitting device may include optical communication equipment, specifically OTN equipment, etc. Correspondingly, the receiving device may also include optical communication equipment, specifically OTN equipment, etc. The specific types of the transmitting device and receiving device can be set according to needs, and the embodiments of the present application do not limit this. Furthermore, the transmitting device may be referred to as a source device, a source node (which may be expressed as Source Node in English), etc., and the receiving device may be referred to as a sink device, a sink node (which may be expressed as Sink Node in English), etc. However, the embodiments of the present application do not limit the names of the transmitting device and receiving device, as long as their functions are realized.

[0066] In practical application, the receiving device may receive the first frame sent from the sending device, analyze the first frame, and obtain the first service, i.e., obtain the data of the first service. In this way, the above conditions 1, 2, 3, and 4 can increase the overhead in the frame structure, and the above condition 5 can shorten the frame length. Thus, the appearance frequency of the overhead in the frame structure of the first frame can be increased, which can shorten the protection switching time of the OTN system, and as a result, the processing efficiency of service data can be improved, i.e., the transmission efficiency of service data can be improved.

[0069] In practical application, the number of FASs included in each row in the frame structure of the second frame can be set according to needs, and the number of FASs included in each row can be the same or different. For example, as shown in Figure 6, the first row in the frame structure of the second frame may include two FASs, and the second, third, and fourth rows may each include one FAS.

[0070] In practical application, the receiving device may receive the second frame sent from the sending device, analyze the second frame, and obtain the second service, i.e., obtain the data of the second service, thereby increasing the number of FASs in the second frame and improving the alignment speed of the second frame.

[0071] For the above problem 3, the embodiment of the present application further provides a data processing method applied to a sending device, and as shown in FIG. 7, the method includes the following step 701: Step 701 is to map a third service into a third frame, i.e., to carry, encapsulate or place data of the third service into the third frame, and each row in the frame structure of the third frame includes at least one MFAS.

[0072] Wherein, in one embodiment, as shown in FIG. 7, the method may further include the following step 702: Step 702 is to transmit the third frame, ie, to the receiving device.

[0073] In practical application, the number of MFASs included in each row in the frame structure of the third frame can be set according to needs, and the number of MFASs included in each row may be the same or different. For example, as shown in Figure 8, each row in the frame structure of the third frame may include one MFAS.

[0074] In practical application, the receiving device may receive the third frame transmitted from the transmitting device, analyze the third frame, and obtain the third service, i.e., obtain the data of the third service, thereby increasing the number of MFASs in the third frame and improving the multi-frame alignment speed of the third frame.

[0075] For the above problem 4, the embodiment of the present application further provides a data processing method applied to a sending device, as shown in FIG. 9, the method includes the following step 901: Step 901 is to map a fourth service into a fourth frame, i.e., to carry, encapsulate or place data of the fourth service into the fourth frame, wherein the overhead of the fourth frame includes first information, the first information being for one-way delay measurement, and the first information includes at least a first timestamp, which indicates the time when the first information is placed (which may be understood as insertion) into the fourth frame.

[0076] Wherein, in one embodiment, as shown in FIG. 9, the method may further include the following step 901: Step 901 is to transmit the fourth frame, that is, to transmit the fourth frame to a receiving device.

[0077] In actual application, the first information may be referred to as DM information, 1DM information, 1DM message, etc., but the embodiments of the present application do not limit the name of the first information as long as its function is realized.

[0078] In practical applications, the length of the first information can be set according to needs. For example, the length of the first information may be a multiple of 8, such as 8 bytes, 16 bytes, 32 bytes, etc.

[0079] In practical application, the first information may be placed in the overhead of the fourth frame, specifically, in an overhead position corresponding to TCM or PM, in other words, the first information may be placed in a TCM field or a PM field.

[0080] In practical application, the time when the first information is placed in the fourth frame, represented by the first timestamp, may be understood as the time when the fourth frame is generated, the time when the first timestamp is generated and placed in the fourth frame, or the time when the fourth service is mapped into the fourth frame by the sending device, i.e., the time when the data of the fourth service is carried, encapsulated, or placed in the fourth frame by the sending device. Also, the first timestamp may represent the time when the fourth frame is emitted, i.e., the time when the fourth frame is transmitted from the sending device to the receiving device. In other words, although there is a time difference between the time when the fourth frame is generated and the time when the fourth frame is emitted, this time difference may be ignored.

[0081] In practical application, the format of the first timestamp can be set according to needs. For example, as shown in Figure 10, the first timestamp may include a 32-bit nanosecond part (which may be expressed as Nanoseconds in English) and a 32-bit second part (which may be expressed as Seconds in English).

[0082] In practical application, the receiving device may receive the fourth frame sent from the sending device, analyze the fourth frame, and obtain the fourth service, i.e., obtain the data of the fourth service.

[0083] In practical application, after receiving the fourth frame, the receiving device may perform a one-way delay measurement. Specifically, the receiving device may calculate the difference between a sixth timestamp and the first timestamp to obtain the one-way delay measurement result. The sixth timestamp represents the time when the fourth frame is received by the receiving device, and the format of the sixth timestamp may be the same as that of the first timestamp. For example, as shown in FIG. 11 , a source node (i.e., the transmitting device) may send an 8-byte 1DM message (i.e., the first information) to a sink node (i.e., the receiving device), where bytes 1 to 8 in the 1DM message may be a timestamp (i.e., the first timestamp) at which an OSU frame (i.e., the fourth frame) was generated. Specifically, when generating an OSU frame, the source node may place the timestamp of when the OSU frame was generated in the overhead area of ​​the OSU frame. When receiving the OSU frame, the sink node may calculate the difference between the time when the OSU frame was received (i.e., the sixth timestamp) and the timestamp included in the OSU frame to obtain a one-way delay measurement result. In this way, one-way delay measurement based on timestamps (i.e., the first timestamp and the sixth timestamp) is realized, thereby improving the accuracy of one-way delay measurement.

[0084] In practical application, the time at which the fourth frame is received by the receiving device, represented by the sixth timestamp, may be understood as the time at which the fourth frame is received by the receiving device and the sixth timestamp is generated; in other words, the sixth timestamp is generated at the same time as the fourth frame is received by the receiving device.

[0085] For the above problem 4, the embodiment of the present application further provides a data processing method applied to a sending device, and as shown in FIG. 12, the method includes the following step 1201: Step 1201 is to map a fifth service into a fifth frame, i.e., to carry, encapsulate or place data of the fifth service into the fifth frame, wherein the overhead of the fifth frame includes second information, the second information being for two-way delay measurement, and the second information includes at least a second timestamp, the second timestamp representing the time when the second information is placed into the fifth frame.

[0086] Wherein, in one embodiment, as shown in FIG. 12, the method may further include the following step 1202: Step 1202 is to transmit the fifth frame, that is, to transmit the fifth frame to the receiving device.

[0087] In actual application, the second information may be referred to as DM information, 2DM information, 2DM message, etc., but the embodiments of the present application do not limit the name of the second information as long as its function is realized.

[0088] In practical applications, the length of the second information can be set according to needs. For example, the length of the second information may be a multiple of 8, such as 8 bytes, 16 bytes, 32 bytes, etc.

[0089] In practical application, the second information may be arranged in the overhead of the fifth frame, specifically, in the TCM field or PM field.

[0090] In practical application, the time when the second information is placed in the fifth frame, represented by the second timestamp, may be understood as the time when the fifth frame is generated, the time when the second timestamp is generated and placed in the fifth frame, or the time when the fifth service is mapped into the fifth frame by the sending device, i.e., the time when the data of the fifth service is carried, encapsulated, or placed in the fifth frame by the sending device. Also, the second timestamp may represent the time when the fifth frame is emitted, i.e., the time when the fifth frame is transmitted from the sending device to the receiving device. In other words, although there is a time difference between the time when the fifth frame is generated and the time when the fifth frame is emitted, this time difference may be ignored.

[0091] In practical application, the format of the second timestamp may be the same as or different from the format of the first timestamp, but the embodiments of the present application are not limited thereto.

[0092] In practical application, the receiving device may receive the fifth frame sent from the sending device, analyze the fifth frame, and obtain the fifth service, i.e., obtain the data of the fifth service.

[0093] In practical application, in order to enable the transmitting device to perform two-way delay measurement, the receiving device may send a sixth frame to the transmitting device after receiving the fifth frame, and the overhead of the sixth frame includes third information, which is for two-way delay measurement, and the third information includes at least the second timestamp, third timestamp, and fourth timestamp, where the third timestamp represents the time when the fifth frame was received by the receiving device, and the fourth timestamp represents the time when the third information was placed in the sixth frame.

[0094] Based on this, in one embodiment, the method comprises: The method may further include receiving a sixth frame, i.e., receiving the sixth frame transmitted from the receiving device, wherein the overhead of the sixth frame includes third information, the third information being for two-way delay measurement, and the third information including at least the second timestamp, third timestamp, and fourth timestamp, the third timestamp representing the time when the fifth frame was received by the receiving device, and the fourth timestamp representing the time when the third information was placed in the sixth frame.

[0095] In practical applications, the third information may be referred to as DM information, 2DM information, 2DM message, or two-way delay measurement response (2DMR, 2DM Response) message, etc., but the embodiments of the present application are not limited to the name of the third information, as long as its function is realized.

[0096] In practical applications, the length of the third information can be set according to needs. For example, the length of the third information may be a multiple of 8, such as 8 bytes, 16 bytes, 32 bytes, etc.

[0097] In practical application, the third information may be arranged in the overhead of the sixth frame, specifically, in the TCM field or PM field.

[0098] In practical applications, the third timestamp and the first timestamp may have the same or different formats, and the fourth timestamp and the first timestamp may have the same or different formats, but the embodiments of the present application are not limited thereto.

[0099] In practical application, the time at which the fifth frame is received by the receiving device, represented by the third timestamp, may be understood as the time at which the fifth frame is received by the receiving device and the third timestamp is generated; in other words, the third timestamp is generated by the receiving device at the same time as the fifth frame is received.

[0100] In practical application, the time when the third information is placed in the sixth frame, represented by the fourth timestamp, may be understood as the time when the sixth frame is generated or the time when the fourth timestamp is generated and placed in the sixth frame. Also, the fourth timestamp may represent the time when the sixth frame is emitted, i.e., the time when the sixth frame is transmitted from the receiving device to the transmitting device. In other words, although there is a time difference between the time when the sixth frame is generated and the time when the sixth frame is emitted, this time difference may be ignored.

[0101] In practical application, after receiving the sixth frame, the transmitting device may perform two-way delay measurement based on the time when the sixth frame was received (hereinafter referred to as the fifth timestamp), as well as the second timestamp, the third timestamp, and the fourth timestamp.

[0102] Based on this, in one embodiment, the method comprises: The method may further include determining a result of a two-way delay measurement based on the second timestamp, the third timestamp, the fourth timestamp, and the fifth timestamp, the fifth timestamp representing the time when the sixth frame was received by the transmitting device.

[0103] The fifth timestamp and the first timestamp may have the same format or different formats, but the embodiment of the present application is not limited thereto.

[0104] In practical application, the time at which the sixth frame is received by the transmitting device, represented by the fifth timestamp, may be understood as the time at which the sixth frame is received by the transmitting device and the fifth timestamp is generated; in other words, the fifth timestamp is generated at the same time as the sixth frame is received by the transmitting device.

[0105] In practical application, the sending device may calculate the difference between the third timestamp and the second timestamp, and the difference between the fifth timestamp and the fourth timestamp, respectively, and use the two obtained differences as the result of the two-way delay measurement; alternatively, the sending device may first calculate the difference between the third timestamp and the second timestamp, and the difference between the fifth timestamp and the fourth timestamp, respectively, and then calculate the average value of the two obtained differences, and use the obtained average value as the result of the two-way delay measurement.

[0106] In practical application, as shown in FIG. 13 , a source node (i.e., the sending device) may send an 8-byte 2DM message (i.e., the second information) to a sink node (i.e., the receiving device), where bytes 1 to 8 in the 2DM message may be a timestamp (i.e., the second timestamp) when the OSU frame (i.e., the fifth frame) is generated by the source node. After receiving the 2DM message, the sink node may generate a 24-byte 2DMR message (i.e., the third information) and send the 2DMR message to the source node. Bytes 1 to 8 in the 2DMR message may be a timestamp (i.e., the second timestamp) when the OSU frame sent from the source node is received by the sink node. Bytes 9 to 16 in the 2DMR message may be a timestamp (i.e., the third timestamp) when the OSU frame sent from the source node is received by the sink node. Bytes 17 to 24 in the 2DMR message may be a timestamp (i.e., the third timestamp) when the OSU frame (i.e., the sixth frame) is generated by the sink node. Specifically, when generating an OSU frame, the source node may place a timestamp of when the OSU frame was generated in the overhead area of ​​the OSU frame. After receiving the OSU frame, the sink node may generate an OSU frame for feedback and feed it back to the source node. When generating the OSU frame for feedback, the sink node may place a timestamp of when the OSU frame was generated by the source node, a timestamp of when the OSU frame transmitted from the source node was received by the sink node, and a timestamp of when the OSU frame was generated by the sink node in the overhead area of ​​the OSU frame. After receiving the OSU frame for feedback, the source node may obtain a bidirectional delay measurement result according to the three timestamps included in the OSU frame and the time when the OSU frame was received (i.e., the fifth timestamp). In this way, bidirectional delay measurement based on timestamps (i.e., the second timestamp, third timestamp, fourth timestamp, and fifth timestamp) is realized, thereby improving the accuracy of the bidirectional delay measurement.

Step 1602 is to analyze the third frame to obtain a third service.

[0110] Accordingly, to address the above problem 4, the embodiment of the present application further provides a data processing method applied to a receiving device, and as shown in FIG. 17, the method includes the following steps 1701 to 1702. Step 1701 is receiving a fourth frame, i.e., receiving the fourth frame transmitted from a transmitting device, wherein the overhead of the fourth frame includes first information, the first information being for one-way delay measurement, and the first information includes at least a first timestamp, which represents the time when the first information is placed in the fourth frame.

According to an aspect of an embodiment of the present application, a new OSU frame (i.e., a Sub-1G frame, i.e., the first frame) for carrying service data is defined in an OTN system. For small bandwidth services (e.g., services with a data transmission rate in the range of 10 Mbps to 10 Gbps), the overhead frequency in the frame structure of the OSU frame is increased by increasing the frame overhead or shortening the frame length. Since the overhead frequency in the frame structure is related to the protection switching time of the OTN system, the protection switching time of the OTN system can be shortened, and as a result, the processing efficiency of service data can be improved, i.e., the transmission efficiency of service data can be improved.
