Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The rapid increase of user network information flow promotes the rapid development of communication network information transmission broadband, the interface bandwidth speed of communication equipment is gradually increased from 10M to 100M, and further increased to 1G and 10G, and the interface bandwidth of the current communication network is increased to 100G and gradually popularized in the market. Although 400G optical modules have been developed, the price of the optical modules is high, even exceeds the price of 4 100G optical modules, and in practical application, the 4 100G optical modules are often bundled to form a large-speed transmission channel to replace the expensive 400G optical modules. Fig. 1 is an exemplary diagram of 400G channel generation in the prior art, and referring to fig. 1, in the embodiment of the present application, a large-speed transmission is formed by bundling 4 100G optical modules through a FlexE protocol to form a 400G transmission channel.

Currently, the FlexE protocol is defined according to the physical layer 100G rate, and in the optical module, before a data packet of 100G is sent, a data packet may be subjected to 64//66 coding, that is, a 64-bit data block is expanded into a 66-bit information block, 2-bit data is added before the 64-bit data block as a start flag of the 66-bit information block, and then the 66-bit information block is sent from an optical port of the optical module. Upon receiving a message, the optical interface distinguishes a 66-bit information block from the received data stream and then recovers the original 64-bit data block from the 66-bit block. The FlexE protocol is located in a 64-bit block to 66-bit block conversion layer, and before sending a 66-bit data block, the 66-bit information block is sorted and planned, fig. 2 is an exemplary diagram of arrangement and planning of the 66-bit information block provided in an embodiment of the present application, referring to fig. 2, for a 100G service, every 20 66-bit data blocks may be divided into one data block group, and each group may have 20 data blocks in total, which represent 20 time slots, and each time slot may identify a service speed of 5G bandwidth. When transmitting a 66-bit information block, a common FlexE overhead block is inserted every 1023 data block groups (1023 20 data blocks) are transmitted, and after inserting the overhead block, the data block is continuously transmitted, and when transmitting 1023 data block groups and inserting the common overhead block, it can be understood that the interval between two adjacent overhead blocks is 1023 20 data blocks.

When physical components of 4 paths 100G are bundled into a logical service bandwidth of 400G, fig. 3 is a schematic diagram of data block allocation on multiple physical channels according to an embodiment of the present application, referring to fig. 3, each physical layer forms a data block group according to 20 data blocks, an overhead block is inserted every 1023 data block groups, and in shim layer of FlexE, 4 paths 20 data blocks are assembled into a data block group consisting of 80 data blocks, where there are 80 time slots in the block group. Customer traffic may be delivered in 80 slots, each slot having a bandwidth of 5G, resulting in a total of 400G of traffic delivery bandwidth.

The FlexE overhead block may be a 66-bit overhead block, and when the service data stream is sent, an overhead block is inserted into every 1023 × 20 data blocks, and the overhead block may perform a positioning function in the entire service stream, and may quickly find the position of the first data block group of the service and the position of the subsequent data block groups through the overhead block. Fig. 4 is a schematic structural diagram of an overhead block data frame according to an embodiment of the present invention, and referring to fig. 4, 8 consecutive overhead blocks constitute an overhead frame. An overhead block consists of a 2-bit block flag and 64-bit block content. The block flags are in the first 2 columns, the last 64 columns are block contents, the block flag for the first overhead block is 10, and the block flags for the last 7 overhead blocks are 01 or SS (SS indicates content uncertainty). The contents of the first overhead block are: 0x4B (8 bits, 4B in hexadecimal), C bit (1 bit, indicating adjustment control), OMF bit (1 bit, indicating an overhead frame multiframe indication), RPF bit (1 bit, indicating a far-end defect indication), RES bit (1 bit, reserved bit), FlexE group number (20 bits, indicating the number of a bundle group), 0x5(4 bits, 5 in hexadecimal), 000000(28 bits, all of which are 0). Where 0x4B and 0x5 are the flags of the first overhead block, when an overhead block is received and the corresponding positions in the overhead block are found to be 0x4B and 0x5, it means that the overhead block is the first overhead block in the overhead frame, and the next consecutive 7 overhead blocks form an overhead frame. In the overhead frame, the reserved part is reserved content, which is not defined yet, see fig. 4, black block. In the FlexE protocol, 8 overhead blocks are defined to form a frame, where the first overhead block is identified by two fields, 4B (16, identified as 0x4B) and 05(16, identified as 0x 5). When the corresponding positions in the overhead block are detected to be 4B and 05 contents, it indicates that the overhead block is the first overhead block, and the following 7 overhead blocks constitute one frame.

Fig. 5 is a schematic diagram of a channel-carried client service provided in an embodiment of the present application, and for the client service, 64/66 encoding is performed first, a client data stream is cut into 64-bit (8-byte) long block information, and then the 64-bit information is encoded to become a 66-bit information block. The traffic stream becomes a 66 bit length information block stream after 64/66 encoding. These information blocks are divided into two types: a data block (the first two bits are 01 indicating that the block is a data block) and a control block (the first two bits are 10 indicating that the block is a data block), the two information blocks being distinguished by the first two bits in the information block. The control information block may be divided into various control information blocks (e.g., idle information blocks) and distinguished by the first byte in the control information block. After 64/66 encoding of the client information, rate adjustment is achieved by adding or deleting free information blocks, and then 66-bit information blocks are placed in corresponding positions in a FlexE protocol-defined time slot planning table (calendar) according to the time slot configuration situation. The FlexE protocol provides a flexible transmission channel for client services, and the size of the transmission channel can be flexibly adjusted according to the bandwidth requirement of a client. The FlexE protocol only provides a pipeline for a client, and does not provide an Operation, Administration and Maintenance (OAM) capability of the quality of service of the pipeline, so that the quality of service of the pipeline cannot be monitored in real time, and a reference signal for service protection switching cannot be provided. An OAM information function is added in the current proposal to realize the monitoring function of the service quality of the customer service flow. As shown in fig. 6, after the client service is encoded with 64/66 bits, the first block of a client message is an S block (first block), then a D block (data block), and finally a T block (last block). There may be several I blocks (idle blocks), O blocks (failure information blocks), etc. between code blocks of two previous and next packets, and an OAM information block may be added between two packets. Fig. 7 is a schematic diagram of the positions of free blocks in a client service code block in an embodiment of the present application, and referring to fig. 7, OAM information is transmitted together with client data message information, the OAM information and the client data message transmission path are completely consistent, and the service quality of a FlexE client pipeline can be monitored in real time. OAM blocks typically occur at a frequency of 16K (i.e., 16384) code blocks per interval in the customer stream. There are two ways to add OAM information blocks between message code block streams: alternative and break-in modes. The alternative mode is to replace the I-block (idle block) between messages with an OAM information block, as shown in fig. 7, which can only perform the replacement operation if the I-block is encountered. Fig. 8 is an exemplary diagram of forcibly inserting an OAM code block into a customer service code block in the embodiment of the present application, and referring to fig. 8, the forcible insertion mode is to directly insert an OAM information block between messages, and perform operations regardless of whether there is a free block, perform insertion of an OAM code first, and then delete a corresponding number of free blocks when a free block is encountered.

When adding OAM information blocks in a client service flow, the speed of the information flow can be ensured to be unchanged only by deleting a corresponding number of IDLE blocks. The average interval between messages in the Ethernet standard definition is at least 12 bytes, and the interval IDLE positions between messages become IDLE blocks during encoding. When the message length is longer, the ratio of the average 12-byte number of the message intervals to the total message bytes is reduced. It is common for current ethernet devices to support messages of 9600 bytes in length, so that 12 bytes of idle bytes occur for every 9600 bytes of messages. The 9600 byte length messages are programmed into 1200 code blocks when encoded at 64/66, and there are approximately 13.6 9600 messages out of 16384 code block lengths. There are 12 IDLE interval bytes between each 9600 packet, and there are a total of 13.6 × 12 ═ 163.8 IDLE byte code blocks in 13.6 packet intervals of 9600 packets, and these IDLE bytes can be programmed into 20.5 IDLE blocks. Since the 9600 message length is an integral multiple of 8, after encoding, each message tail will be added with a message end block T0, each T0 needs to occupy one idle block, and 13.6 messages need to occupy 14 idle blocks, so that only 7.5 idle blocks remain in the 16384 code block stream period. The Ethernet service has the problem of clock frequency deviation, IDLE addition and deletion are needed to be carried out on plus or minus 100PPM (namely, the maximum deviation is 200PPM, PPM is a unit of one millionth), 3.3 IDLE blocks are needed to carry out speed adjustment on 16384 code block flow period, and 3.3 IDLE blocks are needed to be occupied. Similarly, the AM block and the FlexE overhead block each occupy approximately one free block, so that the number of the remaining free blocks is only 7.5-3.3-1-2.5, that is, only 2 free blocks in a 16K period are left to be used by the OAM block. The number of OAM information blocks is large, and it may require 10 code blocks to be transmitted instantaneously, but in practice only 2, 3 OAM code blocks may be allowed to be transferred, and the problem of multiple OAM burst transfers needs to be solved.

Fig. 9 is a flowchart of an OAM information sending method provided in this embodiment, where an implementation of this application is applicable to a case where OAM information is transmitted in a 400G high-speed channel, and this method may be executed by an OAM information sending apparatus in this embodiment, where this apparatus may be implemented in a software and/or hardware manner, referring to fig. 9, where the method in this embodiment specifically includes the following steps:

step 101, caching at least one type of OAM code block to be sent.

The OAM code block to be sent may be an information data block that needs to be sent through a high-speed channel, and the OAM code block to be sent may store operation information data, management information data, maintenance information data, and the like, and may be used to detect a service quality state of the channel, for example, may be used to detect functions of the channel, such as an error rate, a delay time, and a service discard.

Specifically, because the number of the OAM information blocks is large, the OAM information blocks cannot be sent instantly, the OAM code blocks to be sent that need to be sent can be cached, and the caching can be performed according to different types of the OAM code blocks to be sent. It can be understood that, due to the difference of the information carried by the OAM code block to be sent, the types of the OAM code block to be sent may be different.

Further, on the basis of the embodiment of the above application, the type of the OAM code block to be sent at least includes at least one of a basic OAM information block, an APS information block, a 1DM code block, a 2DMR code block, a CV code block, and a CS code block.

And 102, outputting each OAM code block to be sent according to a preset scheduling mode.

In this embodiment of the application, the preset scheduling mode may be a mode of scheduling the output of the to-be-sent OAM code blocks of each cache, for example, the to-be-sent OAM code blocks may be sequentially output according to the type of the to-be-sent OAM code blocks or sequentially output according to the cache time of the to-be-sent OAM code blocks.

And 103, controlling the total output number of the OAM code blocks to be sent in a preset period.

The preset period may be a transmission period for outputting an OAM code block to be transmitted, and each preset period may be a control period for outputting the OAM code block to be transmitted.

Specifically, when the OAM code blocks to be sent are output, the total output number of the OAM code blocks to be sent output in each preset period may be controlled, for example, the preset period of the OAM code blocks to be sent is 16384 code blocks, each preset period may allow 2 OAM code blocks to be sent, a preset period T ═ 16384 and a total output number sum ═ 2 may be set to control the output of OAM code blocks to be sent, and if the number of the OAM code blocks to be sent exceeds two, the remaining OAM code blocks to be sent need to wait for the next preset period to be sent. By controlling the total output number of the OAM code blocks to be sent in the preset period, the limitation of the number of IDLE blocks to the output of the OAM code blocks to be sent can be solved, and the output number and the real-time performance of the OAM code blocks are improved.

According to the embodiment of the application, different types of OAM code blocks to be sent are cached, the OAM code blocks to be sent are output according to a preset scheduling mode, the total output quantity of the OAM code blocks to be sent is controlled in a preset period, the OAM code block output under a binding channel is realized, the service functions of the channel are enriched, the limit of the IDLE block quantity on the output OAM code blocks is reduced, the output quantity of the OAM code blocks to be sent is increased, and the real-time performance of the channel on control response can be enhanced.

Further, on the basis of the embodiment of the foregoing application, the caching at least one type of OAM code block to be sent includes: and caching each OAM code block to be sent according to the priority corresponding to the type.

In this embodiment of the present application, when the OAM to be sent is cached according to the type, a priority may be preset for the type of the OAM to be sent, and the OAM code blocks to be sent may be cached sequentially according to the order of the type priorities, for example, the order of the priority is arranged from high to low, the basic OAM information block may have the highest priority, and then the APS code block triggered by the event may be used, and the priorities of the remaining periodic APS code blocks may be the same as the priorities of the code blocks such as the 1DM code block, the 2DMM, the 2DMR, the CV code block, and the CS code block.

Fig. 10 is a flowchart of an OAM information sending method provided in this embodiment of the present application, which is embodied based on the foregoing embodiment of the present application, and determines priorities of time APS code blocks and period APS code blocks in OAM code blocks to be sent when caching, referring to fig. 10, a method according to this embodiment of the present application may include the following steps:

and step 111, the APS information blocks in the OAM code blocks to be sent at least include event APS code blocks and periodic APS code blocks, and the event APS code blocks and/or the periodic APS code blocks are cached according to the same high priority.

Specifically, the APS information block may be triggered to transmit in two ways, for example, when an emergency failure event occurs, the APS information block is output 3 times, each transmission interval may be 3.3 milliseconds, and belongs to the emergency notification transmission, and then the APS information block may be repeatedly transmitted once per second, and the APS may be divided into an event APS code block triggered by the emergency event and a periodic APS code block periodically transmitted according to a trigger scenario.

Due to two generation modes of APS information blocks, the transmission priority requirements are different, but the original APS information generation time sequence is still kept in the transmission sequence, if the priority of the periodic APS code block is lower, the event APS code block is generated to be transmitted in the process of waiting for transmission, and the event APS code block has high priority, but if the prior periodic APS code block with low priority is not transmitted, the event APS code block with high priority cannot be transmitted, the event APS code block with high priority can be transmitted only after the prior APS code block with low priority is transmitted, or the prior APS code block with low priority is discarded, and then the APS code block with high priority is transmitted. In the embodiment of the application, the same high priority can be set for the period APS code block and the event APS code block, and other types of OAM code blocks to be sent can be lower than the period APS code block and the event APS code block.

And step 112, outputting each OAM code block to be sent according to a preset scheduling mode.

Specifically, the scheduled output may be performed according to the priority of the type of each OAM code block to be sent, and since the event APS code block and the period APS code block have the same high priority, the event APS code block or the period APS code block may not be distinguished when the OAM code block is output, and the event APS code block and the period APS code block are output as the same APS information block. It is also possible to distinguish between event APS code blocks and periodic APS code blocks, but event APS code blocks and periodic APS code blocks have the same priority and are output only in time order among event APS code blocks and periodic APS code blocks at the time of output.

And 113, controlling the total output number of the OAM code blocks to be sent in a preset period.

Specifically, when the OAM code blocks to be sent are output, the total output number of the OAM code blocks to be sent output in each preset period may be controlled.

In the embodiment of the application, the event APS code blocks and the periodic APS code blocks are set to have the same high priority, and the event APS code blocks and the periodic APS code blocks are scheduled in the same preset mode when output, so that timely response of fault information is realized, and the reliability of channel transmission can be improved.

Fig. 11 is a flowchart of an OAM information sending method provided in this embodiment of the present application, which is embodied based on the foregoing embodiment of the present application, and determines priorities of time APS code blocks and period APS code blocks in OAM code blocks to be sent when caching, referring to fig. 11, a method according to this embodiment of the present application may include the following steps:

step 121, the APS information block in the OAM code block to be sent at least includes an event APS code block and a period APS code block, the event APS code block and/or the period APS code block are cached according to the same high priority, and the cached period APS code block is removed when the event APS code block is cached.

In the embodiment of the application, due to the fact that the timeliness requirements of the event APS code block and the information carried by the periodic APS code block are different, the information carried by the periodic APS code block can be invalid when the channel sends the event APS code block, and in order to improve the output efficiency of the OAM code block to be sent, the periodic APS code block which exists in the buffer but is not sent can be removed when the event APS code block is cached.

Specifically, the same high priority can be set for event APS code blocks and period APS code blocks in the OAM code blocks, and the corresponding types of OAM code blocks to be sent are cached according to the priority.

And step 122, outputting each OAM code block to be sent according to a preset scheduling mode.

And 123, controlling the total output number of the OAM code blocks to be sent in a preset period.

According to the method and the device, the same high priority is set for the event APS code blocks and the periodic APS code blocks, the same preset scheduling mode is adopted for the event APS code blocks and the periodic APS code blocks during output, timely response of fault information is achieved when the event APS code blocks are cached, and reliability of channel transmission can be improved.

Fig. 12 is a flowchart of an OAM information sending method provided in this embodiment, which is embodied based on the foregoing embodiment, and in this embodiment, an OAM code block to be sent is output in a two-level scheduling manner, and is output by polling scheduling in the same priority, and then output by priority scheduling according to different priorities, referring to fig. 12, the method in this embodiment may include the following steps:

step 201, caching at least one type of OAM code blocks to be sent.

Step 202, the OAM code blocks to be sent belonging to the same priority are output by polling scheduling.

The polling scheduling may be a manner of sequentially outputting OAM code blocks to be transmitted in order.

In this embodiment of the application, the OAM code blocks to be sent with the same priority may be output by polling scheduling first, the output probabilities in the OAM code blocks to be sent with the same priority are the same, and the OAM code blocks to be sent with the same priority may be output fairly, and a cached OAM code block to be sent may be output at the same time. It can be understood that, because the OAM code blocks to be sent may be of multiple priorities, multiple code blocks to be sent may be output after polling scheduling is adopted in the code blocks to be sent of the same priority, and the number of the code blocks to be sent may correspond to the number of the priorities.

And step 203, adopting priority scheduling to output the output OAM code blocks to be sent with different priorities.

Specifically, because the priority levels of the to-be-sent OAM code blocks output in the same priority level are different, a plurality of to-be-sent OAM code blocks can be output according to the number of the priority levels, because only one OAM code block can be output at a time, the to-be-sent OAM code blocks can be scheduled and output according to different priority levels, the high-priority to-be-sent OAM code block is output first, and the low-priority to-be-sent OAM code block is output later.

And 204, controlling the total output quantity of the OAM code blocks to be sent in a preset period.

In this embodiment of the application, the total output number of the to-be-sent OAM code blocks in one preset period may be constant, and by performing polling scheduling output in the same priority and performing priority scheduling output in different priorities, when the number of the to-be-sent OAM code blocks output in the preset period reaches the total output number, the to-be-sent OAM code blocks that are not output yet may wait for the next preset period to be sent.

According to the embodiment of the application, the cached OAM code blocks to be sent are output in a two-stage scheduling mode, the OAM code blocks to be sent with the same priority are output in a polling scheduling mode, the OAM code blocks to be sent with different priorities are output in a scheduling mode according to the priority, balanced output of the OAM code blocks to be sent is achieved, and stability of a large-speed channel is improved.

Fig. 13 is a flowchart of an OAM information sending method provided in this embodiment, which is embodied based on the foregoing embodiment, and the OAM code block to be sent is output in a two-level scheduling manner, and is output by polling scheduling in a low priority interior, and then output by priority scheduling according to different priorities, referring to fig. 13, the method in this embodiment may include the following steps:

step 211, caching at least one type of OAM code block to be sent.

And step 212, outputting the OAM code block to be sent belonging to the low priority by adopting polling scheduling.

In the embodiment of the application, the OAM code blocks to be transmitted may be divided into at least three priority levels according to different types of the OAM code blocks to be transmitted, may at least include a high priority level, a medium priority level, and a low priority level, and may divide an OAM code block to be transmitted, which is more and less important, into a low priority level. For example, the basic OAM information block may be classified into a high priority, the APS information block may be classified into a medium priority, the 1DM code block, the 2DMR code block, the CV code block, the CS code block, and the like may be classified into a low priority.

Specifically, because a large number of basic OAM information blocks with high priority and APS information blocks with medium priority are not simultaneously sent in a burst manner under normal conditions, OAM code blocks with low priority are sent as needed, and there is a possibility of simultaneous activation, when the first-layer output scheduling is performed, the polling scheduling can be performed only in the OAM code blocks to be sent with low priority, so that only one OAM code block to be sent with low priority is output at one moment, and the OAM code blocks are prevented from being output too much to affect the customer service transmitted by the high-speed channel.

And step 213, adopting priority scheduling to output the OAM code blocks to be transmitted with the rest priorities and the OAM code blocks to be transmitted with the low priority output by the polling scheduling.

Specifically, when performing output scheduling of the second layer, priority scheduling output may be performed on the to-be-transmitted OAM code block output by the polling scheduling of the first layer and the to-be-transmitted OAM code blocks of other priorities, and the to-be-transmitted OAM code blocks may be sequentially output according to the priorities.

And step 214, controlling the total output number of the OAM code blocks to be sent in a preset period.

According to the technical scheme, the OAM code blocks to be sent are output in a two-stage scheduling mode, the OAM sending function of a high-speed channel is achieved, the safety of the channel is improved, polling scheduling is only performed in the low-priority OAM code blocks to be sent, the total output quantity is conveniently controlled, and the reliability of the channel is improved.

Fig. 14 is a flowchart of an OAM information sending method provided in this embodiment, which is embodied based on the foregoing embodiment, and outputs an OAM code block to be sent in a first-level scheduling or multi-level scheduling manner based on a priority of each OAM code block to be sent, referring to fig. 14, where the method in this embodiment may include the following steps:

step 221, caching at least one type of OAM code block to be sent.

Step 222, outputting according to the priority of each sent OAM code block, where each sent OAM code block with different priorities is output by priority scheduling, and each sent OAM code block with the same priority is output by polling scheduling.

In this embodiment of the application, the OAM code blocks to be sent may be divided into at least three priority levels according to different types of the OAM code blocks to be sent, and may at least include a high priority level, a medium priority level, and a low priority level, and the OAM code blocks to be sent, which are more in number and are unimportant, may be divided into the low priority levels. For example, the basic OAM information block may be classified into a high priority, the APS information block may be classified into a medium priority, the 1DM code block, the 2DMR code block, the CV code block, the CS code block, and the like may be classified into a low priority.

Specifically, when the OAM code block to be sent is output according to the priority scheduling, the OAM code block to be sent may be output in a one-level scheduling manner or a multi-level scheduling manner, for example, a two-level scheduling manner may be adopted, polling scheduling output may be performed in the to-be-sent blocks with the same priority, and the to-be-sent OAM code blocks are sequentially output according to the priority scheduling in an order from a high priority to a low priority. Priority scheduling and polling scheduling output can be simultaneously completed in a primary scheduling mode, OAM code blocks to be sent with different priorities are scheduled by adopting priority, and OAM code blocks to be sent with the same priority are scheduled by polling.

And 223, controlling the total output number of the OAM code blocks to be sent in a preset period.

According to the embodiment of the application, the polling scheduling is used at the same priority level, and the priority scheduling is used at different priority levels to realize the output of the cached OAM code block to be sent, so that the functions of a transmission channel are enriched, and the reliability of a customer service channel is improved.

Further, on the basis of the embodiment of the application, the controlling the total output number of the OAM code blocks to be sent in a preset period includes:

and in a preset period, controlling the total output quantity of the OAM code blocks to be sent which are output by adopting priority scheduling.

In this embodiment of the present application, the OAM code blocks to be sent may be output through priority scheduling and/or polling scheduling, and the total number of OAM code blocks to be sent that are output through priority scheduling may be limited by controlling the number of the OAM code blocks to be sent that are output through priority scheduling in a preset period.

Further, on the basis of the above application embodiment, in a preset period, the total output number of the to-be-sent OAM code blocks that are output by polling scheduling is controlled.

In this embodiment of the present application, the OAM code blocks to be sent may be output through priority scheduling and/or polling scheduling, and the total number of OAM code blocks to be sent that are output through polling scheduling may be limited by controlling the number of the OAM code blocks to be sent that are output through polling scheduling in a preset period. For example, when polling scheduling is performed in each same priority, the output number of the to-be-transmitted OAM code blocks of each priority may be controlled, so as to achieve the effect of controlling the total output number. When polling scheduling output is performed only in low priority, the limitation of the total output number of the OAM code blocks to be transmitted can be achieved by limiting the output number of the OAM code blocks of low priority.

Illustratively, the OAM information sending method in this embodiment may be implemented by three modules, which may be a cache module, a scheduling module, and an output control module. Fig. 15 is an exemplary diagram of an OAM information transmitting method provided in an embodiment of the present application; referring to fig. 15, in the embodiment of the present application, the scheduling module may include two stages and three groups of scheduling sub-modules, where the OAM code blocks to be sent with the same priority are scheduled by polling, and the OAM code blocks to be sent with different priorities are scheduled by priority. The priority of the Base code block and the APS code block is high, and the two OAM code blocks can be scheduled first and output the transmitted code blocks. And other low-priority code blocks such as a 1DM code block, a 2DMM code block, a 2DMR code block, a CV code block and a CS code block are uniformly scheduled, and the output of the low-priority group is output. Then, the high-priority output and the low-priority output are unified to carry out scheduling output according to the priority, the high-priority output is output first, and the low-priority output is output later. The scheduling output is controlled by the output control module, and only a fixed number of OAM blocks can be output in one period.

In another embodiment, the OAM information sending method may be implemented by three modules, which may be a cache module, a scheduling module, and an output control module. Fig. 16 is an exemplary diagram of an OAM information sending method provided in this embodiment, and a scheduling module may still use a two-level and three-group scheduling manner, but fig. 16 is different from the method shown in fig. 15, and when an event APS code block occurs when a cache module processes an APS cache, the cache module may delete a period APS code block that has been cached, which may improve the priority of the event APS code block and improve the failure processing efficiency.

In an exemplary real-time manner, the APS code blocks may be divided into event APS code blocks and periodic APS code blocks, and the OAM information transmission method may be implemented by three modules, which may be a cache module, a scheduling module, and an output control module. Fig. 17 is an exemplary diagram of an OAM information sending method provided in this embodiment, and referring to fig. 17, the method shown in fig. 17 is mostly the same as that in fig. 16, except that an APS code block adopts a high-priority and low-priority separate buffer mode, an event APS code block may be queued for sending in high priority, and a periodic APS code block is queued for sending in low priority. When the event APS code block appears, all the periodic APS code blocks in the low-priority queue are deleted, so that the transmission sequence of the high-priority APS code blocks and the low-priority APS code blocks can be kept unchanged.

Illustratively, the OAM information sending method may be implemented by three modules, which may be a cache module, a scheduling module and an output control module, the scheduling module may adopt two-stage and two-group scheduling modes, the former stage has only one scheduling submodule to complete the scheduling of the low-priority OAM block, and the second stage completes the scheduling of the base code block, the APS block and the low-priority code block. Fig. 18 is basically the same as fig. 15 except for the structure of the scheduler. As APS code blocks can have three processing modes, APS processing mode 1: the priority is not distinguished, and the processing is carried out according to the high priority; a scheduling mode; APS processing method 2: scheduling according to high priority, but directly deleting low priority periodic APS code blocks to be sent by event-triggered high priority APS code blocks; APS processing method 3: queuing according to high and low priority levels respectively, but the APS code block with high priority triggered by the event can directly delete the code block in the APS code block queue with low priority period to be sent. The three processing modes, such as fig. 18, fig. 19, and fig. 20, may be generated when the scheduler uses two-stage two-group scheduling modes and different APS code block processing modes are combined. Fig. 18 and 15, fig. 19 and 16, and fig. 20 and 17 are basically the same except for the combination pattern generated by the difference in the internal structure of the scheduler.

Further, on the basis of the above application embodiments, the scheduling module may also use a primary scheduling mode, which is completed by the primary scheduler at the same time, and the primary scheduler completes the priority and polling functions at the same time, where OAM code blocks with different priorities are scheduled by priority first, and OAM code blocks with the same priority are scheduled by polling, as shown in fig. 21. Similarly, since the APS code block may have three different processing manners, the OAM information transmission method may generate the three manners shown in fig. 21, 22, and 23.

In another real-time mode, the OAM information sending method may be implemented by three modules, which may be a cache module, a scheduling module, and an output control module. Fig. 24 is an exemplary diagram of an OAM information transmitting method provided in an embodiment of the present application, and referring to fig. 24, for a high-priority base code block and an APS code block, a large number of base code blocks and APS code blocks are generally not simultaneously burst-transmitted. The low-priority OAM code blocks on demand, such as 1DM code block, 2DMM, 2DMR, CV code block and CS code block, may be simultaneously enabled on demand, and simultaneously need to be transmitted within an instant time segment, resulting in a burst phenomenon, so the essence of the control module is to control the total number of transmissions, the control module may control on the rear scheduler, or may directly control on the low-priority scheduler, as long as the output of the low-priority scheduler is controlled, the total output number is controlled. Since the APS code block may have three processing manners, correspondingly, the scheduling module in the form of two-stage three-group scheduling may have three manners shown in fig. 24, fig. 25, and fig. 26. In the same class, the scheduling module adopting the two-stage two-group method may have three methods shown in fig. 27, 28 and 29.

The above is an exemplary embodiment of the present application, and may be composed of three parts, namely, a cache module, a scheduling module, and a control module, where the APS code block in the cache module has 3 processing modes, the scheduling module has three different structures, and the control module has 2 different positions, which are combined to generate different specific forms, and these different forms are all within the scope of the present application.
