The method for determining the normal Ethernet message and the abnormal Ethernet message in the original customer service flow by the sending end comprises the following steps: a sending end judges whether all information blocks in each Ethernet message are formed by sequentially arranging 1 data packet head S block, N continuous data packet D blocks and 1 data packet tail T block in an original client service flow, wherein N is an integer greater than or equal to 3; if all information blocks in the Ethernet message are not formed by sequentially arranging 1 data packet head S block, N continuous data packet D blocks and 1 data packet tail T block, the sending end determines that the Ethernet message is an abnormal Ethernet message; if all the information blocks in the Ethernet message are formed by sequentially arranging 1 data packet head S block, N continuous data packet D blocks and 1 data packet tail T block, the sending end determines that the Ethernet message is a normal Ethernet message.

And step 403, the sending end sends the service flow of the bearing client to the receiving end according to the Flexe protocol.

The sending end sends the bearing client service flow to the receiving end according to the Flexe protocol, and the receiving end receives the bearing client service flow sent by the sending end according to the Flexe protocol.

Specifically, a sending end encodes a 64-bit information block carrying a client service stream into a 66-bit information block according to a FlexE protocol to obtain an encoded client service stream; wherein, the 66-bit information block comprises a 66-bit data block and a 66-bit overhead block; the continuous 8 overhead blocks with 66 bits form an overhead frame, and OAM information is carried in the overhead frame; and then, the sending end sends the encoded bearing client service flow to the receiving end.

The receiving end firstly receives the encoded bearing client service flow sent by the sending end; then, the receiving end decodes the 66-bit information block of the encoded bearing client service flow into a 64-bit information block according to a Flexe protocol to obtain the bearing client service flow; wherein, the 66-bit information block comprises a 66-bit data block and a 66-bit overhead block; and the continuous 8 overhead blocks with 66 bits form an overhead frame, and the OAM information is carried in the overhead frame.

Step 404, the receiving end extracts the OAM information in the customer service flow.

The receiving end extracts OAM information in the customer service flow according to the characteristic pattern format of the OAM information determined by the sending end; wherein, the OAM information includes: first customer characteristic information, an insertion timestamp value, fault state information, automatic protection information, sender flag information, and the like; the first client characteristic information is obtained by the sending end calculating the characteristic information of the target client service flow according to the preset algorithm.

Here, further, the receiving end has a determination step before extracting the OAM information, and determines a normal ethernet packet and an abnormal ethernet packet in the received service flow of the bearer client.

The receiving end extracts the OAM information in the customer service flow according to the characteristic pattern format of the OAM information determined by the sending end, and the method comprises the following steps: the receiving end extracts OAM information carried in abnormal Ethernet messages in the service flow of the load client according to the characteristic pattern format of the load OAM information determined by the sending end; the characteristic pattern format is determined by the sending end according to the arrangement sequence of all the information blocks in the abnormal Ethernet message.

The receiving end determines normal Ethernet messages and abnormal Ethernet messages in the customer service flow, and the method comprises the following steps: a receiving end judges whether all information blocks in each Ethernet message are formed by sequentially arranging 1 data packet head S block, N continuous data packet D blocks and 1 data packet tail T block in a customer service flow, wherein N is an integer greater than or equal to 3; if all information blocks in the Ethernet message are not formed by sequentially arranging 1 data packet head S block, N continuous data packet D blocks and 1 data packet tail T block, the receiving end determines that the Ethernet message is an abnormal Ethernet message; if all the information blocks in the Ethernet message are formed by sequentially arranging 1 data packet head S block, N continuous data packet D blocks and 1 data packet tail T block, the receiving end determines that the Ethernet message is a normal Ethernet message.

After step 404, the receiving end processes the extracted OAM information to obtain a detection result of the bearer channel, and specifically, the receiving end may perform steps 405a to 405f for detecting the quality status of the bearer channel and obtaining the detection result; the receiving end can execute steps 406a to 406b for the detection of the propagation delay time of the bearer channel and obtaining the detection result; the receiving end can execute steps 407a to 407b for detecting whether the bearer channel is interrupted and obtaining a detection result; the three detection tasks may be executed respectively and simultaneously after step 404, or may be executed respectively in sequence, and the specific execution mode may be set according to actual requirements, which is not limited herein.

Step 405a, the receiving end determines whether the target customer service flow for calculating the second customer characteristic information is the same as the target customer service flow for calculating the first customer characteristic information at the sending end.

The receiving end judges whether the target customer service flow for calculating the second customer characteristic information is the same as the target customer service flow for calculating the first customer characteristic information at the sending end, if the target customer service flow for calculating the second customer characteristic information is not the same as the target customer service flow for calculating the first customer characteristic information at the sending end, step 405b is executed; if the target client traffic flow for calculating the second client characteristic information is the same as the target client traffic flow for calculating the first client characteristic information at the transmitting end, step 405c is executed.

And step 405b, finishing the task of detecting the quality condition of the bearing channel.

And the receiving end finishes the detection task aiming at the quality condition of the bearing channel.

And 405c, the receiving end calculates the characteristic information of the target client service flow by adopting a CRC algorithm to obtain second client characteristic information.

And the receiving end calculates the characteristic information of the target client service flow by adopting the same CRC algorithm used by the sending end to obtain second client characteristic information.

Step 405d, the receiving end compares whether the second client characteristic information is consistent with the first client characteristic information.

The receiving end compares whether the second client characteristic information is consistent with the first client characteristic information, if so, the step 405e is executed; if the second customer characteristic information is not consistent with the first customer characteristic information, step 405f is performed.

And 405e, the receiving end determines that the error code does not occur in the bearer channel to obtain a detection result of the quality condition of the bearer channel.

For example, when the receiving end compares that the second client characteristic information is consistent with the first client characteristic information, it is determined that no error code occurs in the bearer channel, and the detection result of the quality status of the bearer channel can be obtained as excellent.

And 405f, the receiving end determines that the error code occurs in the bearer channel to obtain a detection result of the quality condition of the bearer channel.

For example, when the receiving end compares that the second client characteristic information is inconsistent with the first client characteristic information, it is determined that an error code occurs in the bearer channel, and it can be obtained that the detection result of the quality status of the bearer channel is bad.

Step 406a, the receiving end obtains the extraction time value of the OAM information.

And the receiving end acquires the extraction time value of the OAM information to obtain the time value when the OAM information is extracted.

And step 406b, the receiving end obtains a detection result of the transmission delay time of the bearer channel according to the extraction time value and the insertion timestamp value of the OAM information.

And the receiving terminal obtains the detection result of the transmission delay time of the bearing channel according to the difference value between the extraction time value of the extracted OAM information and the inserted timestamp value in the OAM information.

Step 407a, the receiving end acquires a receiving time interval of the OAM information.

The receiving time interval for the receiving end to acquire the OAM information is, for example, 30 seconds, where the OAM information is received once, that is, the receiving time interval for the receiving end to acquire the OAM information is 30 seconds.

Step 407b, the receiving end obtains the detection result whether the bearer channel is interrupted according to the receiving time interval of the OAM information.

The receiving end obtains the detection result whether the bearing channel is interrupted or not according to the receiving time interval of the OAM information; the receiving end compares the size of the receiving time interval with the size of a preset interval to obtain a detection result of whether the bearing channel is interrupted; for example, the receiving end determines that the receiving time interval is greater than the preset interval of 20 seconds by 30 seconds, so that it can be determined that the bearer channel is interrupted, and a detection result that the bearer channel is interrupted is obtained.

It should be noted that, in the embodiment of the present invention, the detection result of the bearer channel is specifically obtained only by using the first client characteristic information and the insertion timestamp value in the OAM information by the receiving end, and for other characteristic information contents in the OAM information, such as various types of characteristic information, such as failure state information, automatic protection information, and sending end flag information, the receiving end may obtain the detection result of the corresponding bearer channel through processing.

The method for processing OAM information of a bearer channel provided by the embodiment of the invention generates OAM information of a client service through a sending end; the sending end inserts OAM information of the customer service into the original customer service flow to obtain a load-bearing customer service flow; the sending end sends the bearing client service flow to the receiving end according to the Flexe protocol, and meanwhile, the receiving end receives the bearing client service flow sent by the sending end according to the Flexe protocol; the receiving end extracts OAM information in the customer service flow; the receiving end respectively carries out different processing on different characteristic information in the OAM information to obtain detection results of the bearing channels corresponding to the different characteristic information; according to the scheme of the invention, under a Flexe protocol, a sending end generates OAM information of client services containing different characteristic information and sends the OAM information to a receiving end through a client service stream, and the receiving end obtains detection results of respective bearing channels corresponding to the different characteristic information by extracting the OAM information in the client service stream and analyzing the OAM information, so that the OAM function of the bearing channels of the client services is realized, a monitoring means aiming at the bearing channels is added, and the service quality of the bearing channels can be monitored in real time.

To further illustrate the object of the present invention, the above embodiments are specifically illustrated by way of example.

At present, a FlexE protocol is defined according to a physical layer 100G rate, in a sending end, before a data packet of a client service stream of 100G is sent, 64/66-bit encoding is performed on the data packet according to an 64/66-bit encoding table in the FlexE protocol, a 64-bit data block is expanded into a 66-bit data block, an added 2 bit is located in front of the 66-bit block and serves as a start mark of the 66-bit data block, and then the data packet is sent out from a sending port of the sending end in a 66-bit data block manner; when the receiving end receives the data message, the receiving port distinguishes 66-bit blocks from the received client service stream, and then recovers the original 64-bit data blocks from the 66-bit data blocks according to the 64/66 coding table in the FlexE protocol, and reassembles the data message of the client service stream.

Fig. 5 is a schematic structural diagram of a 66-bit data block and a 66-bit overhead block in an embodiment of the method for processing OAM information of a bearer channel according to the present invention; the FlexE protocol is in a conversion layer from 64 bits to 66 bits, and before sending a 66-bit data block, the 66-bit data block is sorted and planned, as shown in fig. 5, for 100G service, every 20 66-bit data blocks are divided into a data block group, 20 data blocks in each group represent 20 time slots, and each time slot represents a service speed of 5G bandwidth; when a 66-bit data block is sent, after 1023 data block groups (1023 × 20 data blocks) are sent, a 66-bit FlexE overhead block is inserted, as shown by a black block in fig. 2, after the FlexE overhead block is inserted, the data block is continuously sent, after the second 1023 × 20 data blocks are sent, the FlexE overhead block is inserted, and so on, so that the FlexE overhead blocks are periodically inserted in the process of sending the data block, the interval between two adjacent FlexE overhead blocks is 1023 × 20 data blocks, and finally a 66-bit information block is formed, wherein the 66-bit information block comprises the 66-bit data block and the 66-bit FlexE overhead block.

Fig. 6 is a schematic diagram of a time slot planning table of a FlexE protocol according to an embodiment of the method for processing OAM information of a bearer channel of the present invention; when the physical layers (100G PHY) of the 4-way 100G are bundled into a logical service bandwidth of 400G, as shown in fig. 6, each physical layer still forms a data block group according to 20 data blocks, and a FlexE overhead block is inserted into each 1023 data block groups; in shim layer of FlexE, 4 paths of 20 data blocks are assembled into a data block group consisting of 80 data blocks, the group has 80 time slots, customer service is transmitted in the 80 time slots, the bandwidth of each time slot is 5G, and the total service transmission bandwidth is 400G.

The FlexE overhead block has a positioning function in the whole client service flow, and the receiving end finds the FlexE overhead block, so that the position of the first data block group and the position of the subsequent data block group in the client service flow can be known.

Fig. 7 is a schematic structural diagram of a FlexE overhead frame in an embodiment of the method for processing OAM information of a bearer channel according to the present invention; as shown in fig. 7, 8 consecutive FlexE overhead blocks constitute one FlexE overhead frame; one FlexE overhead block is composed of a block flag of 2 bits and a block content of 64 bits, the block flag is located in the first 2 columns, the following 64 columns are block contents, the block flag of the first FlexE overhead block is 10, and the block flags of the following 7 FlexE overhead blocks are 01 or SS (SS indicates that the contents are uncertain); the contents of the first FlexE overhead block are: 0x4B (8 bits, 4B in hexadecimal), C bit (1 bit, indicating adjustment control), OMF bit (1 bit, indicating overhead frame multiframe indication), RPF bit (1 bit, indicating far-end defect indication), RES bit (1 bit, reserved bit), Flexe group number (20 bits, indicating number of bundle group), 0x5(4 bits, 5 in hexadecimal), 000000(28 bits, all of which are 0); wherein 0x4B and 0x5 are the flags of the first FlexE overhead block, when a corresponding position in a FlexE overhead block is found to be 0x4B and 0x5 at the time of receiving, it means that the FlexE overhead block is the first FlexE overhead block in a FlexE overhead frame, and 7 FlexE overhead blocks received consecutively a FlexE overhead frame is composed into a FlexE overhead frame; in the FlexE overhead frame, the reserved portion is reserved content, which is not yet defined, as shown in the gray block portion of fig. 7; in the FlexE protocol, 8 FlexE overhead blocks are defined to form one FlexE overhead frame, wherein the first FlexE overhead block is identified by two fields of 4B (16 m, identified as 0x4B) and 05(16 m, identified as 0x 5); when the corresponding positions in the FlexE overhead block are detected to be 4B and 05 content, it indicates that the FlexE overhead block is the first FlexE overhead block, and the following 7 FlexE overhead blocks constitute a FlexE overhead frame.

For a 66-bit data block, the data block has two types of information blocks: a data information block (the first two bits are 01, indicating that the block is a data information block) and a control information block (the first two bits are 10, indicating that the block is a control information block), the two information blocks being distinguished by the first two bits in the respective blocks; the control information block can be divided into various control information blocks (such as free information blocks), the control information blocks are distinguished by the first byte in the control information block, after 64/66-bit encoding is carried out on the client service stream, rate adjustment is realized by adding or deleting the free information block, and then 66-bit data blocks are placed in corresponding positions in a time slot planning table (calendar) of a Flexe protocol according to the time slot configuration situation. The structure of the slot planning table is shown in fig. 6, each member in the FlexE protocol is divided into 20 slots (each slot is a 66-bit data block, and each slot represents 5G service bandwidth), and if there are 4 members, the slot planning table has 80 slots in total; by configuration, it is determined that each client service selects those timeslots for carrying, the timeslot planning table groups all timeslots, each group of 20 timeslots is sent to each member defined by the FlexE protocol, and each member adds a FlexE overhead block (the FlexE overhead block is also a 66-bit block, and one FlexE overhead block is inserted into every 20 × 1023 timeslot blocks, as shown in fig. 5); each member in the time slot planning table is a modified time slot planning table (sub-capacity) and is carried on a physical layer (PHY); after the FlexE overhead block is inserted, each PHY scrambles (scrambles) the carried customer service stream, and transmits the scrambled customer service stream through a transmit-receive Port (PMA) of the transmitting end.

At a receiving end, a PMA receives a signal, and a 66-bit information block is recovered through descrambling (descramble); in a 66-bit information block, each PHY searches a Flexe overhead block defined by a Flexe protocol, and extracts all time slots by taking the Flexe overhead block as a position reference point to obtain a sub-calendar; time slots of all members are arranged in sequence, and a calendar structure is restored; according to the configuration information, the client service stream is taken out from the corresponding time slot in the calendar, the free information block is deleted, and then 66/64 bit decoding is carried out to recover the original client service.

When the client service is subjected to blocking and 64/66 bit encoding according to an 64/66 bit encoding table in a Flexe protocol, because the length of a data packet is uncertain, when the client service is cut according to 64 bits, the length of a packet tail can be less than 64 bits, and therefore, the types of the packet tail blocks are various; the S block indicates that the block is the first block of a packet. In the S block, the first byte content is 0x78, which indicates that the block is an S block, and the next 7 bytes of content are packet information; the T block represents the last block of a packet, with 8 different cases: 1. the representation is the last block of the data packet, but the block does not have any data packet content, and the last byte content of the data packet is in the last data block; 2. the representation is the last block of the data packet, and the last byte content in the data packet is only carried in the block; 3. the representation is the last block of the data packet, and the block only carries the content of the last 2 bytes in the data packet; 4. the representation is the last block of the data packet, and the block only carries the content of the last 3 bytes in the data packet; 5. the representation is the last block of the data packet, and the block only carries the content of the last 4 bytes in the data packet; 6. the representation is the last block of the data packet, and the block only carries the content of the last 5 bytes in the data packet; 7. the representation is the last block of the data packet, and the block only carries the content of the last 6 bytes in the data packet; 8. the representation is the last block of the data packet, and the last 7 bytes of contents in the data packet are carried in the block; if all of the data in a data packet is data, it is data block D. When there is no data information, an Idle block is directly inserted, indicating a free block (I block).

By 64/66 bit encoding, a data packet is converted into a series of sequential 66 bit block streams, the first 66 bit block of the packet being an S block, the last 66 bit block being a T block, and between the S and T blocks being D blocks. Two data packets may be immediately adjacent, i.e. the T block (last block) of the previous packet is followed by the S block (first block) of the next packet; the two previous and next messages may not be adjacent, i.e. after T of the previous message and before S block of the next message, one or more I blocks are inserted between the two messages.

When a sending end carries out 64/66 bit encoding on client service, inserting OAM information (OAM information in the above embodiment) between client service flows of front and back two data packets (original client service flows in the above embodiment) to obtain a new client service flow (carrying client service flow in the above embodiment), then sending the new client service flow to a receiving end by the sending end, and carrying out subsequent processing by the receiving end according to the new client service flow, so that the OAM information and the client service message information are transmitted together, the transmission paths of the OAM information and the client service information are completely consistent, and the receiving end can monitor the service quality of a Flexe carrying channel in real time.

When the receiving end recovers the customer service, the receiving end determines and extracts which of the 66-bit information blocks are data information blocks and which are OAM information blocks according to a configuration rule determined in advance with the sending end, if the information blocks are the OAM information blocks, the receiving end extracts characteristic information in the OAM information blocks for analysis, and the quality condition of a bearing channel can be monitored; for example, 1, if the receiving end does not receive the OAM information within a certain time, it is determined that the bearer channel is interrupted; 2. the receiving end can calculate the transmission time of the bearing channel according to the time value of the OAM information when the OAM information is sent and the time value of the OAM information when the OAM information is received; 3. the receiving end calculates the characteristic information of the target client service flow between the two sections of OAM information (the characteristic information of the target client service flow is the result of performing operation on the target client service flow according to a set of algorithm, for example, performing CRC8 algorithm operation on the target client service flow by using CRC8 algorithm to obtain an operation result, or performing XOR operation on the target client service flow by bit by using XOR budget algorithm to obtain an operation result); and then comparing the information with the characteristic information carried in the OAM information, so that whether the error code occurs in the information in the bearing channel can be diagnosed, and the service quality condition of the channel can be given.

Fig. 8 is a schematic structural diagram of an OAM information block according to an embodiment of the method for processing OAM information of a bearer channel of the present invention, as shown in fig. 8, which is data information blocks and which is OAM information blocks need to be distinguished by some special marks;

the OAM information block is an information block of a group of characteristic pattern formats, the minimum length of a normal Ethernet data message is 64 bytes, and one information block can only carry 8 bytes (64 bits) at most, so that after 64/66 bits are coded on one Ethernet message, a plurality of information blocks are arranged according to a certain sequence, the information block format is formed by an S block (a first data packet block) + N continuous D blocks (data packet data blocks) + a T block (data packet tail blocks), and the information blocks of three types are formed according to the sequence, wherein the N continuous D blocks are at least 3, namely N is an integer greater than or equal to 3; if the information block flow does not conform to the arrangement sequence, the information block flow is not a normal Ethernet message, so that the sequence which does not conform to the information code of the Ethernet message is defined as a characteristic pattern format of the OAM information; for example, in fig. 9a, which will be described later, the S block + T block format is defined as a characteristic pattern format of OAM information, and an OAM information stream segment is formed; when the characteristic pattern format of the S block + T block is detected in the information block stream, the S block and the T block are judged to be OAM information blocks instead of the S block and the T block of the data message.

The OAM information block carries monitoring information, and an S block (the content of a first byte is 78, which represents the S block) carries a Client number (Client _ no), a multiframe sequence number, monitoring information (PM1 to PM3) and CRC information; the client number can be designed to monitor a specific client service flow, the multiframe number is used for expanding PM1 to PM3 bytes, a plurality of monitoring bytes are formed by PM1 to PM3 bytes in a plurality of continuous frames, functions of error code monitoring and the like are provided, and the CRC information provides correctness detection of an OAM information block; in the T block (the content of the first byte is 87, which means that it is the T block), there are Automatic Protection Switching (APS) information and Delay time stamp (DT); as described above for the example of the OAM information carried by the S block and the T block, how to carry the OAM information may be set in a user-defined manner, for example, the OAM information may be all placed in the S block, the OAM information may be all placed in the T block, and part of the OAM information may be placed in the S block and part in the T block; the specific setting can be carried out according to actual requirements, and is not limited herein.

When a sending end inserts an OAM information block into a customer service flow, the OAM information block needs to be inserted between two data messages after the former section of data message and before the latter section of data message, namely between a T block and an S block in the customer service flow; sometimes, the client service flow is not at full rate, the two messages are not continuous, and an idle information block (I block) is inserted between the two messages, so that the OAM information block is inserted between the I blocks.

After inserting an OAM information block into a client service stream by a sending end and sending the OAM information and the client service stream to a receiving end, the receiving end needs to be capable of correctly identifying which of the client service stream are data information blocks and which are OAM information blocks; because the length of the data message has a certain limit, for example, the minimum length of the Ethernet message is 64 bytes, after 64/66-bit encoding, 10 66-bit blocks (1S block carrying 7 bytes of data; 7 data blocks (D block) carrying 56 bytes of data; 1T block carrying 1 byte of data) are provided; for normal Ethernet messages, when a plurality of data blocks (D blocks) exist between the S block and the T block; when there is no D block between the S block and the T block, or there is few D blocks, or there is an I block between the S block and the T block, the client traffic flow is an abnormal data flow, and can be defined as carrying the contents of the OAM information block.

Therefore, when the sending end inserts the OAM information or before the OAM information is inserted, the sending end and the receiving end need to be in advance commented and well adopt a characteristic pattern format for bearing the OAM information; there are various characteristic pattern formats for carrying OAM information, which are specifically shown below.
