Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a code block processing method, apparatus, device and readable storage medium. Background Technology

[0002] With the development of 5G and the increase in users in vertical industries, the demand for network slicing is increasing. The industry has conducted many beneficial explorations in Ethernet-based slicing isolation technology, and Metro Transport Network (MTN) is a new transport network technology system defined for the needs of new services such as 5G.

[0003] MTN consists of a metropolitan area network (MAN) segment layer and a MAN path layer. At the segment layer, MTN technology supports channel partitioning and slicing with a minimum granularity of 5Gbps. MTN reuses the frame format of Flexible Ethernet (FlexE) at the segment layer. The basic data unit frame format at the segment layer consists of a 64B / 66B code block with one overhead plus a 64B / 66B code block with 20460 payloads.

[0004] Currently, above the MTN channel layer, a finer-grained MTN (fgMTN) slice channel is provided, offering even smaller bandwidth granularity. fgMTN adds an fgMTN layer to the MTN path (MTNP) layer structure, and its bitstream consists of fgMTN cell structures and operation, administration, and maintenance (OAM) code blocks and idle blocks between these cell structures. Error handling methods need to be considered during fgMTN processing. Summary of the Invention

[0098] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0099] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0100] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0101] As described in the background section, fgMTN adds an fgMTN layer to the MTNP layer structure, and the bitstream is composed of fgMTN unit structures and OAM code blocks and IDLE blocks between the unit structures. During fgMTN processing, it is necessary to consider how to handle code block errors received by the node. Unlike existing transmission technology systems, the fgMTN unit structure consists of 66-byte code blocks, but customer information is not directly incorporated into the fgMTN unit; instead, it is placed in the data byte portion of the fgMTN unit code block. Therefore, the error code block identification mechanism needs to consider both the processing of outer fgMTN unit code blocks and inner customer signal code blocks, as well as the interaction between the two.

[0102] Therefore, this application provides a code block processing method to propose a processing method for error identifiers and a handling mechanism for abnormal situations, thereby ensuring the reliability of the MTN network and the uniformity of abnormal situation handling.

[0103] See Figure 1 , Figure 1 This is a flowchart of the code block processing method provided in the embodiments of this application, applied to MTN nodes, such as... Figure 1 As shown, it includes the following steps:

[0104] Step 101: If the MTN channel code block carrying the fgMTN channel is incorrectly marked, or the code block contains an invalid synchronization header, or the code block is a control code block with an invalid type field, or the code block is an error code block, replace the fgMTN channel code block carried in the MTN channel code block with the error code block.

[0105] Specifically, in this step, one or more client code blocks of the fgMTN channel carried within the MTN channel code block are replaced with error code blocks. That is, a code block in the MTN channel layer may correspond to and carry one or more client code blocks of the fgMTN channel, and these one or more client code blocks of the fgMTN channel are all replaced with error code blocks (E code blocks). Here, the fgMTN channel code block is the code block corresponding to the fgMTN channel.

[0106] In this context, "code block mismarking" refers to incorrectly marking a problematic code block at the MTN section level, such as changing the synchronization header to 11. "Code block containing an invalid synchronization header" means that, according to the IEEE 802.3 code block format, the first two synchronization bits of a 66-bit code block (66B code block) should be 01 or 10. If they are other values ​​(e.g., 11 or 00), the synchronization header is invalid. "Control code block with an invalid type field" refers to a control code block (e.g., T1 to T7 code blocks) where the type field after the two synchronization bits does not conform to the IEEE 802.3 code block format; therefore, the type field is invalid. "Error code block" refers to an E code block in the 66B code block type specified by IEEE 802.3.

[0107] like Figure 2 As shown, taking the fgMTN unit as an example, the client signal (or information) in the fgMTN unit occupies 64 bits of the 66B code block of the fgMTN unit, excluding the 2-bit synchronization header. A client 66B code block carries a length of 66 bits (greater than the 64-bit length that can be occupied by a 66B code block in the fgMTN unit). Therefore, a client 66B code block needs to occupy the fillable bits of two code blocks in the fgMTN unit. The fillable portion of a 66B code block in the fgMTN unit cannot be one-to-one with a client 66B code block. This results in the 64 bits within a 66B code block of the same fgMTN unit potentially being associated with one or two client code blocks of the fgMTN channel (e.g., the 64 bits). It's possible that the filler consists of 2 bits from the preceding fgMTN channel client code block and 62 bits from the following fgMTN channel client code block, with the remaining 4 bits of the following fgMTN channel client code block needing to be filled in the next 66B code block of the fgMTN unit. In this case, one or more corresponding fgMTN channel client code blocks carried within it need to be replaced with E code blocks (for example, if 64 bits of an fgMTN unit code block are filled with 2 bits from the preceding fgMTN channel client code block and 62 bits from the following fgMTN channel client code block, then during error handling, both the preceding and following fgMTN channel client code blocks need to be replaced with E code blocks). Here, fgMTN unit refers to the fgMTN multiplexing unit frame (Fine-grain MultiplexUnit, FGMU) carried in the MTN channel (MTNP). Since fgMTN units are directly carried in the MTN channel (MTNP), fgMTN unit code blocks belong to MTNP code blocks.

[0108] This application proposes a method for handling error identification of fgMTN channel code blocks, thereby effectively ensuring the reliability of fgMTN technology and network.

[0109] Optionally, after the client code block replaces the E code block, when the MTN node regenerates the fgMTN unit at the transmitting end, it replaces the erroneous code block used to carry the client code block with a data code block (D code block) or an end code block (T code block) to obtain the first target fgMTN unit. That is, the 66B code block of the fgMTN unit will use 64 bits of a normal data code block or an end code block to store the client signal's E code block. In other words, the 66B code block of the regenerated fgMTN unit will be a normal data code block or an end code block, not an E code block. Optionally, the MTN node can then transmit this first target fgMTN unit.

[0110] like Figure 3 The diagram shows the frame code block structure at the detection and transmission ends of an MTN node. For example, in... Figure 3 In the process, at the detection end, if an erroneous code block is detected that is used to carry the client code block, it is replaced with a data code block at the sending end.

[0111] If the MTN node has FEC functionality, in the event of an anomaly in the FEC codeword length detection, the 66B code block within the FEC codeword length range will be replaced with an erroneous code block. When processing the fgMTN unit subsequently, if an FEC error is identified as an E code block, the node can proceed according to the aforementioned step 101 and the MTN node's method of regenerating the fgMTN unit at the transmitting end.

[0112] In this embodiment, the fgMTN unit includes a start code block (S code block), a data code block (D code block), and an end code block (T code block). Furthermore, this embodiment also provides a method for handling errors or anomalies occurring in these code blocks.

[0113] See Figure 4 , Figure 4 This is a flowchart of the code block processing method provided in the embodiments of this application, applied to MTN nodes, such as... Figure 4 As shown, it includes the following steps:

[0114] Step 401: Receive the second target fgMTN unit.

[0115] The second target fgMTN unit can refer to any fgMTN unit.

[0116] Step 402: If the target code block of the second target fgMTN unit is abnormal, the target code block is processed.

[0117] The target code block includes one or more of a start code block, a data code block, and an end code block. For example... Figure 5 As shown, 501 represents the structure of a data block, 502 represents the structure of the start block, and 503 represents the structure of the end block, all including a 2-bit sync header. By judging the sync header or the block type field, the type of error that has occurred in the target block can be determined. For example, if the sync header or the block type field is marked as erroneous, then a corresponding error can be considered to have occurred.

[0118] Optionally, when the target code block includes different code blocks, there are different processing methods.

[0119] 1. The target code block includes the start code block.

[0120] In the event of a start block synchronization header error, the start block and the second target fgMTN unit are discarded; or, in the event of a start block synchronization header error, if the target block is determined to be a start block (e.g., inferred from other information, such as a data block immediately following the target block), the second target fgMTN unit is read, that is, the second target fgMTN unit is not discarded, and the content following the fgMTN unit (such as overhead, client blocks, etc.) is still used.

[0121] In the event of a start block block type field error, the start block and the second target fgMTN unit are discarded; alternatively, in the event of a start block block type field error, if the target block is determined to be a start block (e.g., inferred from other information, such as a data block immediately following the target block), the second target fgMTN unit is read. That is, the second target fgMTN unit is not discarded, and the content following the fgMTN unit (such as overhead, client blocks, etc.) is still used.

[0122] 2. The target code block includes a data code block.

[0123] In the event of a data block synchronization header error:

[0124] If the data code block carries fgMTN channel customer information, replace one or more fgMTN channel customer code blocks carried in the 64 bits of the data code block with an error code block; or, if the data code block carries overhead information, discard the overhead information.

[0125] 3. The target code block includes the end code block.

[0126] In the event of an end-of-block synchronization header error or a block type field error:

[0127] If the end code block carries fgMTN channel client information, replace the 64 bits of the end code block carrying an fgMTN channel client code block with an error code block; or, if the end code block carries overhead information, discard the overhead information.

[0128] The above embodiments propose an anomaly handling scheme for different types of code blocks in fgMTN units, thereby ensuring the uniformity of anomaly handling and ensuring the reliability of the MTN network.

[0129] in, Figure 4 The methods shown can be implemented individually or in combination. Figure 1 The illustrated embodiment is implemented.
