[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] The following, in conjunction with the accompanying drawings, describes in detail the service transmission method, electronic device and storage medium provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0022] Figure 1 A service transmission method provided by an embodiment of the present invention is shown. The method can be executed by an electronic device, and the electronic device may include: a server and / or a terminal device. In other words, the method can be executed by software or hardware installed in the electronic device, and the method includes the following steps:

[0023] Step 102: Map the customer service to multiple time slots of the service layer.

[0024] In an embodiment of the present application, the customer service can be mapped to the service layer for transmission. Specifically, the customer service can be carried in a fine grain Optical Transport Network (fgOTN) container, and then the fgOTN carrying the customer service can be mapped to multiple time slots of the service layer to achieve mapping the customer service to multiple time slots of the service layer. The service layer can be an optical payload unit (Optical Payload Unit, OPU). fgOTN is a technology used to carry small-grain services in the optical transport network. Low-speed customer services such as E1, Fast Ethernet (Fast Ethernet, FE), Synchronous Transfer Module (Synchronous Transfer Module-1, STM-1), etc. are efficiently carried through fgOTN containers.

[0025] Step 104: Carry the mapping overhead information in the overhead area of ​​the service layer.

[0026] In an embodiment of the present application, it is necessary to carry the mapping overhead information representing the customer service to the service layer in the overhead area of ​​the service layer, wherein the mapping overhead information needs to be carried in multiple time slot overheads of the service layer, and the above-mentioned multiple time slot overheads are in the overhead area of ​​the service layer.

[0027] In one implementation, the time slot used to carry customer services and the time slot overhead used to carry mapping overhead information correspond one to one, that is, in the service layer, after the customer service is mapped to the time slot, the mapping overhead information needs to be carried in the time slot overhead corresponding to the time slot.

[0028] In the service layer, a multi-frame method can be used to carry customer services, that is, the service layer can be divided into multiple service layer frames, and the number of service layer frames is positively correlated with the number of time slots in the service layer.

[0029] In one implementation, each service layer frame carries a second number of time slot overheads, and the second number is greater than 1. That is, each service layer frame may include multiple time slot overheads, for example Figure 2 As shown, the service layer frame OPU includes an OPU payload area and an OPU overhead area, the OPU payload area includes multiple time slots (TS), the OPU overhead area includes 4 time slot overheads (TS OH), and also includes PSI (Payload Structure Indication) overhead, and the time slot overhead for carrying mapping overhead information can be located in multiple service layer frames. By carrying the second number of time slot overheads in the service layer frame, the number of service layer frames used to carry mapping overhead information is reduced, and the transmission period of the mapping overhead is shortened.

[0030] Step 106: Transmit the customer service and mapping overhead information through the service layer.

[0031] Specifically, after mapping the customer service to multiple time slots in the service layer and carrying the mapping overhead information in the multiple time slot overheads, the customer service and the mapping overhead information can be transmitted through the service layer.

[0032] The service transmission method provided by the embodiment of the present invention maps the customer service to multiple time slots of the service layer; carries the mapping overhead information of the customer service to the service layer in the overhead area of ​​the service layer, wherein the mapping overhead information is carried in the multiple time slot overheads of the service layer, and the time slot overhead is in the overhead area of ​​the service layer; transmits the customer service and the mapping overhead information through the service layer, maps the mapping overhead information in multiple time slot overheads, so that each time slot overhead can bear part of the mapping overhead information, so that each time slot overhead can transmit the mapping overhead information with less overhead, thereby reducing the transmission pressure of each time slot overhead and improving the transmission efficiency of the customer service and the mapping overhead.

[0033] In one implementation, the mapping overhead information includes a first number of bits, where the first number is related to the number of time slots occupied by the client traffic in the service layer.

[0034] Specifically, the above-mentioned mapping overhead information consists of a first number of bits, and the first number is related to the number of time slots occupied by the customer service in the service layer.

[0035] In one implementation, the mapping overhead information includes:

[0036] The number of padding blocks in the service layer; or the deviation between the number of data blocks used by the service layer to carry customer services and the preset benchmark number of data blocks.

[0037] Specifically, the above-mentioned mapping overhead information includes the number of padding blocks in the service layer, or includes the deviation between the number of data blocks used by the service layer to carry customer services and the preset number of benchmark data blocks. Among them, the padding block can also be called a 16-byte padding block, and the data block can also be called a 16-byte data block. The padding block and the data block have a fixed length. The padding block is used to carry padding data of a fixed pattern. The padding block can be all 0s, and the data block is used to carry customer services. The number of padding blocks in the service layer or the deviation between the number of data blocks used by the service layer to carry customer services and the preset number of benchmark data blocks can be obtained by mapping the overhead information.

[0038] In one implementation, the mapping overhead information is carried in a third number of time slot overheads, where the third number is related to the number of time slots occupied by the client service in the service layer.

[0039] Specifically, in the service layer, the mapping overhead information is carried in a third number of time slot overheads, and the third number is related to the number of time slots occupied by customer services in the service layer. For example, if the number of time slots occupied by customer services in the service layer is α, then the third number of time slot overheads is also α.

[0040] In one implementation, each row in the slot overhead carries the same mapping overhead information.

[0041] Specifically, the overhead area of ​​each service layer frame includes multiple rows and columns. For example, the overhead area in each service layer frame includes 3 rows and 2 columns, each column is 1 byte, and the total is 6 bytes. In this way, each time slot overhead can carry multiple rows of mapping overhead information. For example, the overhead area in each service layer frame includes 3 rows and 2 columns, then each row of the time slot overhead can carry mapping overhead information, so that a time slot overhead can carry three rows of mapping overhead information. It is ensured that the mapping overhead information will not be lost. And in the same time slot overhead, the mapping overhead information carried by each row is the same.

[0042] In one implementation, the mapping overhead information is carried in an overhead area of ​​the service layer, including:

[0043] The first N bits of the mapping overhead information are carried in the time slot overhead corresponding to the time slot with the smallest number, and the second N bits of the mapping overhead information are carried in the time slot overhead corresponding to the time slot with the second smallest number, until the third number N bits of the mapping overhead information are carried in the time slot overhead corresponding to the time slot with the largest number; wherein the mapping overhead information is composed of a third number N bits, N is a positive integer, wherein the leftmost bit is the most significant bit, and the rightmost bit is the least significant bit, and N is the number of bits of each time slot overhead used to carry the mapping overhead information.

[0044] Specifically, the number of time slots occupied by the fgOTN container in the service layer OPU may be a third number, and the mapping overhead information of the customer service is represented by the third number * N bits, where N is a positive integer and N is the number of bits of each time slot overhead used to carry the mapping overhead information. The third number of time slots occupied by the customer service is determined by the rate of the fgOTN container, and the third number is an integer greater than or equal to 1. fgOTN containers of different rates have mapping overhead information of different lengths, and the mapping overhead information is carried in multiple time slot overheads corresponding to multiple time slots.

[0045] When the number of time slots occupied by the fgOTN container in the service layer OPU (the third number) is 1, the mapping overhead length of the fgOTN container is N bits, and in one time slot overhead of the service layer OPU frame overhead area corresponding to the time slot, one mapping overhead information is transmitted in each line.

[0046] When the number of time slots occupied by the fgOTN container in the service layer OPU (the third number) is greater than 1, the length of the mapping overhead of the fgOTN container is the third number * N bits, and in one time slot overhead of the service layer OPU frame overhead area corresponding to each time slot, each row transmits N bits of the mapping overhead information, and multiple time slot overheads complete the transmission of multiple mapping overhead information. Each time slot has a number in the service layer OPU, and the method of carrying the mapping overhead information in multiple time slot overheads is to carry the first N bits of the mapping overhead information in the time slot overhead of the service layer OPU frame overhead area corresponding to the time slot with the smallest number, and to carry the second N bits of the mapping overhead information in the time slot overhead of the service layer OPU frame overhead area corresponding to the time slot with the second smallest number, and so on, until the Mth N bits of the mapping overhead information are carried in the time slot overhead of the service layer OPU frame overhead area corresponding to the time slot with the largest number, indicating that in the third number * N bits of the mapping overhead information, the leftmost bit is the most significant bit, and the rightmost bit is the least significant bit.

[0047] In one implementation, the overhead area further includes a reserved overhead, and the reserved overhead includes an overhead that carries a timeslot status, where the timeslot status includes: used, unused, or marked.

[0048] Specifically, the overhead area in the service layer includes not only the time slot overhead but also the reserved overhead. The reserved overhead may also carry the time slot status overhead. The time slot status includes but is not limited to: used, unused, flag, etc.

[0049] In one implementation, the overhead area further includes a reserved overhead, and the reserved overhead includes an overhead of bandwidth adjustment, and the bandwidth adjustment includes: a request, a response, or a rollback command.

[0050] Specifically, in addition to carrying time slot overhead, the overhead area in the service layer can also carry bandwidth adjustment overhead, and the bandwidth adjustment includes but is not limited to commands such as request, response, and fallback.

[0051] The following is a specific example of the service transmission method provided in the embodiment of the present application.

[0052] Embodiment 1: The service layer frame OPU0 is divided into 119 10.411Mbps time slots, and a 10.4Mbps fgOTN container is mapped to OPU0. Each OPU0 frame overhead area supports the time slot overhead transmission of 4 time slots. 32 OPU0 multiframes are used to complete the transmission of 119 time slot overheads. The first frame of the OPU032 multiframe carries the time slot overhead of time slots 1 to 4, and the second frame of the OPU0 32 multiframe carries the time slot overhead of time slots 5 to 8, and so on. Figure 3 shown.

[0053] Step 1: The 10.4 Mbps fgOTN container occupies only one 10.411 Mbps time slot in the service layer OPU0. Assume that the time slot numbered 6 is allocated to the fgOTN container.

[0054] Step 2: Use the number of 16-byte padding blocks in the service layer OPU0 to represent the mapping overhead information. There are a total of 256 16-byte blocks in the service layer OPU0 that carries the 10.4Mbps fgOTN container. It should be noted that the service layer that carries fgOTN is fgODTU, and fgODTU consists of a time slot of the service layer OPU0 frame, that is, fgODTU is part of the service layer OPU0. For the convenience of description, the service layer OPU0 is used for description, and the two have equivalent functions.

[0055] Step 3: According to the rate information of the fgOTN container and the rate information of the time slot and the related rate information deviation (±20ppm), the maximum number of 16-byte padding blocks Cm,max and the minimum number of 16-byte padding blocks Cm,min occupied by the fgOTN container in the service layer OPU0 can be calculated. The minimum number of 16-byte padding blocks is calculated using 256-Cm,max, and the maximum number of 16-byte padding blocks is calculated using 256-Cm,min, which is the mapping overhead information. The value of the calculated mapping overhead information is 0 or 1, and the specific value is determined according to the actual rate of the fgOTN container and time slot.

[0056] Step 4: The mapping overhead information uses 2 bits. When the mapping overhead information is 00, it indicates that the number of 16-byte filling blocks is 0. When the mapping overhead information is 01, it indicates that the number of 16-byte filling blocks is 1.

[0057] Step 5: The overhead area of ​​the service layer OPU0 frame allocates 2 bits per line as time slot overhead. Since the overhead area of ​​an OPU0 frame carries the overhead of 4 time slots, one byte of overhead is also reserved. The reserved one byte of overhead is used to indicate the status information of the time slot. Each status information is allocated 2 bits per line, that is, each time slot overhead includes two parts: time slot mapping overhead and time slot status overhead, such as Figure 4 shown.

[0058] Step 6: On the sending side, the fgOTN container is carried in the service layer OPU0, and the mapping overhead information is carried in the time slot overhead corresponding to time slot 6. Each row carries one mapping overhead information, and three rows carry a total of 3, and each mapping information has the same value.

[0059] Step 7: On the receiving side, extract the mapping overhead information from the overhead of the service layer OPU0 frame corresponding to time slot 6. A total of 3 are extracted. The mapping overhead information is determined according to the principle of majority decision. The number of 16-byte blocks of the fgOTN container carried in the service layer OPU0 is obtained by subtracting the mapping overhead information from 256, and the fgOTN container is extracted from the service layer OPU0.

[0060] Embodiment 2: OPU1 is divided into 238 10.411Mbps time slots, and a 5*10.4Mbps fgOTN container is mapped to OPU1. Each OPU1 frame overhead area supports the time slot overhead transmission of 4 time slots. 64 OPU1 multiframes are used to complete the transmission of 238 time slot overheads. The first frame of OPU1 64 multiframes carries the time slot overheads of time slots 1 to 4, and the second frame of OPU1 64 multiframes carries the time slot overheads of time slots 5 to 8, and so on. Figure 5 shown.

[0061] Step 1: A 5*10.4Mbps fgOTN container occupies five 10.411Mbps time slots in the service layer OPU1. Assume that five time slots numbered #1, #48, #95, #142, and #189 are allocated to the fgOTN container.

[0062] Step 2: Use the number of 16-byte padding blocks in the service layer OPU1 to represent the mapping overhead information. There are a total of 256*5 16-byte blocks in the service layer OPU1 that carries the 5*10.4Mbps fgOTN container. It should be noted that the service layer that carries fgOTN is fgODTU, which consists of five time slots of the service layer OPU1 frame, that is, fgODTU is part of the service layer OPU1. For the convenience of description, the service layer OPU1 is used for description, and the two have equivalent functions.

[0063] Step 3: According to the rate information of the fgOTN container and the rate information of the time slot and the related rate information deviation (±20ppm), the maximum number of 16-byte padding blocks Cm,max and the minimum number of 16-byte padding blocks Cm,min occupied by the fgOTN container in the service layer OPU1 can be calculated. The minimum number of 16-byte padding blocks is calculated using 256*5-Cm,max, and the maximum number of 16-byte padding blocks is calculated using 256*5-Cm,min, which is the mapping overhead information. The value of the calculated mapping overhead information is an integer between 0 and 6, and the specific value is determined according to the actual rate of the fgOTN container and the time slot.

[0064] Step 4: Map the overhead information using 10 bits, with the leftmost bit being the most significant bit and the rightmost bit being the least significant bit:

[0065] When the mapping overhead information is 0000000000, it means that the number of 16-byte padding blocks is 0;

[0066] When the mapping overhead information is 0000000001, it means that the number of 16-byte padding blocks is 1;

[0067] When the mapping overhead information is 0000000010, it means that the number of 16-byte padding blocks is 2;

[0068] When the mapping overhead information is 0000000011, it means that the number of 16-byte padding blocks is 3;

[0069] When the mapping overhead information is 0000000100, it means that the number of 16-byte padding blocks is 4;

[0070] When the mapping overhead information is 0000000101, it means that the number of 16-byte padding blocks is 5;

[0071] When the mapping overhead information is 0000000110, it indicates that the number of 16-byte padding blocks is 6.

[0072] Step 5: 2 bits are allocated per row in the overhead area of ​​the service layer OPU1 frame as time slot overhead. A total of 10 bits of time slot overhead for 5 time slots are used to transmit mapping overhead, wherein the first 2 bits of mapping overhead are carried in the time slot overhead corresponding to time slot #1, the second 2 bits of mapping overhead are carried in the time slot overhead corresponding to time slot #48, the third 2 bits of mapping overhead are carried in the time slot overhead corresponding to time slot #95, the fourth 2 bits of mapping overhead are carried in the time slot overhead corresponding to time slot #142, and the fifth 2 bits of mapping overhead are carried in the time slot overhead corresponding to time slot #189, as shown in FIG. Figure 6 shown.

[0073] Step 6: Since the overhead area of ​​an OPU1 frame carries the overhead of 4 time slots, one byte of overhead is reserved. The reserved one byte of overhead is used to represent the bandwidth adjustment overhead of the time slot, which has a total of 6 bits. That is, each time slot overhead includes two parts: time slot mapping overhead and bandwidth adjustment overhead. For example, Figure 7 shown.

[0074] Step 7: On the sending side, the fgOTN container is carried in the service layer OPU1, and the mapping overhead information is carried in the five time slot overheads corresponding to time slots #1, #48, #95, #142, and #189. Each row of each time slot overhead carries a part of the mapping overhead information. One row of the five time slot overheads completes the transmission of the mapping overhead information. The three rows of the five time slot overheads carry a total of three mapping overhead messages, and each mapping information has the same value.

[0075] Step 8: On the receiving side, extract the mapping overhead information from the overhead of the service layer OPU1 frame corresponding to time slots #1, #48, #95, #142, and #189. A total of 3 are extracted. The mapping overhead information is determined based on the principle of majority decision. The number of 16-byte blocks of the fgOTN container carried in the service layer OPU1 is obtained by subtracting the mapping overhead information from 256*5, and the fgOTN container is extracted from the service layer OPU1.

[0076] It should be noted that the execution subject of the service transmission method provided in the embodiment of the present application may be a service transmission device, or a control module in the service transmission device for executing the service transmission method.
