- the term "and/or” describes the association relationship of the associated objects, indicating that three relationships may exist.
- a and/or B may represent: A exists alone, A and B exist at the same time, and B exists alone.

- fgMTN adds a fgMTN layer to the structure of the MTNP layer, and the code stream is composed of the fgMTN unit structure and the OAM code blocks and IDLE between the unit structures.
- the code stream is composed of the fgMTN unit structure and the OAM code blocks and IDLE between the unit structures.
- the fgMTN unit structure is composed of 66B code blocks, but the customer information does not directly constitute the fgMTN unit, but is placed in the data byte part of the fgMTN unit code block. Therefore, the error code block identification mechanism needs to take into account the processing of the outer fgMTN unit code block and the inner customer signal code block, as well as the linkage relationship between the two.
- an embodiment of the present application provides a code block processing method to propose a processing method for error identification and a processing mechanism for abnormal situations, thereby ensuring the reliability of the MTN network and the uniformity of abnormal situation processing.
- FIG. 1 is a flow chart of a code block processing method provided in an embodiment of the present application, which is applied to an MTN node, and includes the following steps as shown in FIG. 1 :
- 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 Error code block.
- the client code blocks of one or more fgMTN channels carried in the MTN channel code block are replaced with error code blocks. That is, a code block of the MTN channel layer may correspond to and carry one or more client code blocks of fgMTN channels, and the client code blocks of the one or more fgMTN channels are all replaced with error code blocks (E code blocks).
- E code blocks error code blocks
- the fgMTN channel code block is the code block corresponding to the fgMTN channel.
- the code block is incorrectly marked, which means that the problematic code block is incorrectly marked at the MTN section layer (MTN Section), such as changing the synchronization header to 11.
- the code block contains an invalid synchronization header, which means that according to the IEEE 802.3 code block format, the first 2 bits of the synchronization header of the 66-bit code block (66B code block) should be 01 or 10. If it is other values (such as 11 or 00), the synchronization header is an invalid synchronization header.
- the control code block with an invalid type field means that for the control code block (such as T1 to T7 code blocks), the type field (block type field) after the 2-bit synchronization header does not conform to the IEEE 802.3 code block format, which is an invalid type field.
- the error code block refers to the E code block in the 66B code block type specified by IEEE 802.3.
- the client signal (or information) in the fgMTN unit occupies the 64-bit portion of the 66B code block of the fgMTN unit except for the 2-bit synchronization header, and a client 66B code block carried by it is 66 bits in length (greater than the 64-bit length that the 66B code block of the fgMTN unit can occupy). Therefore, a client 66B code block needs to occupy the fillable bits of two code blocks of the fgMTN unit.
- the fillable portion of a 66B code block of the fgMTN unit cannot correspond one-to-one to a 66B code block of the client, resulting in that the 64 bits within the 66B code block of the same fgMTN unit may be associated with the client code blocks of one or two fgMTN channels (for example, the 64 The bits may be filled with 2 bits in the previous fgMTN channel client code block and 62 bits in the next fgMTN channel client code block. The remaining 4 bits of the next fgMTN channel client code block need to be filled in the next 66B code block of the fgMTN unit).
- the corresponding one or more fgMTN channel client code blocks carried inside it need to be replaced with E code blocks (for example, 64 bits of an fgMTN unit code block fill 2 bits in the previous fgMTN channel client code block and 62 bits in the next fgMTN channel client code block.
- E code blocks for example, 64 bits of an fgMTN unit code block fill 2 bits in the previous fgMTN channel client code block and 62 bits in the next fgMTN channel client code block.
- the fgMTN unit refers to the fgMTN multiplexing unit frame (Fine-grain Multiplex Unit, FGMU) carried in the MTN channel (MTNP). Since the fgMTN unit is directly carried in the MTN channel (MTNP), the fgMTN unit code block belongs to the MTNP code block.
- FGMU fgMTN multiplexing unit frame
- a method for processing error identification of fgMTN channel code blocks is proposed, thereby effectively ensuring the reliability of fgMTN technology and network.
- the E code block is placed into the data code block (D code block) or the end code block (T code block) used to carry the client code block to obtain the first target fgMTN unit. That is, the 66B code block of the fgMTN unit will use the 64 bits of the normal data code block or the end code block to place the E code block of the client signal, that is, the 66B code block of the regenerated fgMTN unit will be a normal data code block or end code block, not an E code block. Afterwards, optionally, the MTN node can send the first target fgMTN unit.
- the error code block is placed in the 64-bit position of the data code block or the end code block used to carry the client code block at the sending end, so that the sending fgMTN unit does not need to perceive the error code block carried internally when processing at the subsequent intermediate node, and can process the code block normally, and only parses the client code block when processing at the destination node receiving end to perceive the error code block.
- Figure 3 is a schematic diagram of the frame code block structure at the detection end (Detect end) and the transmission end (Transmit end) of the MTN node.
- Detect end detection end
- Transmit end transmission end
- Figure 3 at the detection end, it is detected that the client code block carried has an error code block, and the detected error code block is replaced with a data code block at the transmission end.
- the MTN node has an FEC function
- the 66B code block within the FEC codeword length range is replaced with an error code block.
- the node can process it according to the aforementioned step 101 and the processing method of the MTN node regenerating the fgMTN unit at the sending end.
- 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).
- S code block start code block
- D code block data code block
- T code block end code block
- the embodiment of the present application also provides a processing method when errors and abnormalities occur in the above code blocks.
- FIG. 4 is a flow chart of a code block processing method provided in an embodiment of the present application, which is applied to The MTN node, as shown in FIG4 , includes the following steps:
- Step 401 Receive a second target fgMTN unit.
- the second target fgMTN unit may refer to any fgMTN unit.
- Step 402 When an abnormality occurs in the target code block of the second target fgMTN unit, process the target code block.
- the target code block includes one or more of a start code block, a data code block, and an end code block.
- 501 is the structure of a data code block
- 502 is the structure of a start code block
- 503 is the structure of an end code block, all of which include a 2-bit sync header.
- the target code block includes different code blocks, there are different processing methods.
- the target code block includes a start code block.
- the second target fgMTN unit is discarded; or, in case of a start code block synchronization header error, if the target code block is determined to be a start code block by a judgment method (for example, the target code block is inferred to be a start code block based on other information, such as the target code block is followed by a data code block), the second target fgMTN unit is read, that is, the second target fgMTN unit is not discarded, and the content after the fgMTN unit (such as overhead, client code block, etc.) is still used.
- a judgment method for example, the target code block is inferred to be a start code block based on other information, such as the target code block is followed by a data code block

本申请实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，并不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如背景技术所描述的，fgMTN在MTNP层的结构中增加一层fgMTN层，由fgMTN单元结构和单元结构之间的OAM码块、IDLE组成码流。在fgMTN的处理过程中，需要考虑节点接收的码块错误情况如何处理。与已有传输技术体系特点不同，fgMTN单元结构由66B码块构成，但客户信息并不是直接组成了fgMTN单元，而是放入了fgMTN单元码块的数据字节部分。因此，错误码块标识机制需要兼顾外层fgMTN单元码块和内层客户信号码块处理，以及两者之间的联动关系。
为此，本申请实施例提供了一种码块处理方法，以提出针对错误标识的处理方法以及异常情况的处理机制，从而确保MTN网络的可靠性以及异常情况处理的统一性。
参见图1，图1是本申请实施例提供的码块处理方法的流程图，应用于MTN节点，如图1所示，包括以下步骤：
步骤101、若携带fgMTN通道的MTN通道码块被错误标记，或者所述码块包含无效的同步头，或者所述码块是具有无效类型字段的控制码块，或者所述码块是错误码块，将所述MTN通道码块内携带的fgMTN通道码块替换为
错误码块。
具体的，在此步骤中，将所述MTN通道码块内携带的一个或多个fgMTN通道的客户码块替换为错误码块。也即，MTN通道层的一个码块内可能对应和携带一个或多个fgMTN通道的客户码块，该一个或多个fgMTN通道的客户码块均被替换为错误码块(E码块)。其中，fgMTN通道码块为fgMTN通道对应的码块。
其中，码块被错误标记指的是在MTN段层(MTN Section)对有问题的码块做错误标记，例如改变同步头为11。码块包含无效的同步头指的是，按照IEEE 802.3码块格式，66比特长度的码块(66B码块)的前2个比特同步头应该为01或者10数值，如果为其他数值(例如11或者00)，则该同步头是无效的同步头。具有无效类型字段的控制码块，指的是对于控制码块(例如T1到T7码块)，2个比特同步头之后的类型字段(block type field)填写数值不符合IEEE 802.3码块格式，则是无效的类型字段。错误码块是指IEEE 802.3所规定的66B码块类型中的E码块。
如图2所示，以fgMTN单元为例，fgMTN单元中客户信号(或信息)占用fgMTN单元的66B码块除了2比特同步头之外的64bit部分，而其携带的一个客户66B码块是66比特长度(大于fgMTN单元的66B码块可占用的64比特长度)，因此，一个客户66B码块需要占用fgMTN单元的两个码块的可填充比特位，fgMTN单元的一个66B码块可填充部分与客户的一个66B码块无法做到一一对应，造成同一个fgMTN单元的66B码块内部的64比特可能关联到一个或两个fgMTN通道的客户码块(例如该64比特有可能填充的是前一个fgMTN通道客户码块中的2比特和后一个fgMTN通道客户码块中的62比特，后一个fgMTN通道客户码块剩余4比特需要在fgMTN单元的下一个66B码块填充)，这时它内部携带所对应的一个或多个fgMTN通道客户码块均需要替换成E码块(例如一个fgMTN单元码块的64比特填充前一个fgMTN通道客户码块中的2比特和后一个fgMTN通道客户码块中的62比特，则在错误处理时其所对应的前一个fgMTN通道客户码块和后一个fgMTN通道客户码块这两个码块都需要替换成E码块)。其中，fgMTN单元指的是在MTN通道(MTNP)中承载的fgMTN复用单元帧(Fine-grain Multiplex Unit，FGMU)，
由于fgMTN单元直接承载在MTN通道(MTNP)中，因此，fgMTN单元码块属于MTNP码块。
在本申请实施例中提出了对fgMTN通道码块的错误标识处理方法，从而有效地保证了fgMTN技术和网络的可靠性。
可选的，在客户码块被替换为E码块之后，MTN节点在发送端重新生成fgMTN单元时，将所述E码块，放置入用于承载客户码块的数据码块(D码块)或结束码块(T码块)，得到第一目标fgMTN单元。也即，fgMTN单元的66B码块将采用正常的数据码块或者结束码块的64比特放置客户信号的E码块，也就是说，重新生成fgMTN单元的66B码块将是正常的数据码块或者结束码块，而非E码块。之后，可选的，MTN节点可发送该第一目标fgMTN单元。
在申请实施例中，通过将被错误标记的MTN通道码块内携带的fgMTN通道码块替换为错误码块，具体是在检测端将fgMTN通道的客户码块替换为所述错误码块之后，在发送端再将所述错误码块放置入用于承载客户码块的数据码块或结束码块的64比特位置，能够使得发送的fgMTN单元在后续中间节点处理时不需要感知内部承载的错误码块，对码块正常处理即可，而仅在目的节点接收端处理时解析客户码块从而感知到错误码块。
如图3所示，图3是在MTN节点的检测端(Detect端)和发送端(Transmit端)的帧码块结构示意图。例如，在图3中，在检测端，检测到承载的所述客户码块存在错误码块，在发送端将检测到的错误码块替换为数据码块。
若所述MTN节点具有FEC功能，在FEC码字Codeword长度检测异常的情况下，将FEC codeword长度范围内的66B码块替换为错误码块。该节点在之后进行fgMTN单元的处理时，由于出现了FEC误码标识为E码块的情况，因此，该节点可按照前述步骤101的方式以及MTN节点在发送端重新生成fgMTN单元的处理方式进行处理。
在本申请实施例中，fgMTN单元包括开始码块(S码块)、数据码块(D码块)和结束码块(T码块)。此外，本申请实施例还提供了一种在上述这些码块出现错误异常的情况下的处理方法。
参见图4，图4是本申请实施例提供的码块处理方法的流程图，应用于
MTN节点，如图4所示，包括以下步骤：
步骤401、接收第二目标fgMTN单元。
其中，所述第二目标fgMTN单元可以指的是任意的fgMTN单元。
步骤402、在所述第二目标fgMTN单元的目标码块出现异常的情况下，对所述目标码块进行处理。
其中，所述目标码块包括开始码块、数据码块、结束码块中的一种或多种。如图5所示，501为数据码块的结构，502为开始码块的结构，503为结束码块结构，均包括2比特的sync(同步)头。通过对同步头或者码块类型域(block type field)的判断，即可得出目标码块发生了何种类型的错误。例如，若同步头或者码块类型域(block type field)被错误标记，则可认为出现了相应的错误。
可选的，所述目标码块包括不同的码块时，有不同的处理方式。
一、所述目标码块包括开始码块。
在出现开始码块同步头错误(sync header)的情况下，丢弃所述第二目标fgMTN单元；或者，在出现开始码块同步头错误的情况下，若所述目标码块是通过判断方式被确定为开始码块(例如根据其他信息推断目标码块为开始码块，如目标码块后面紧跟着的是数据码块)，读取所述第二目标fgMTN单元，也即，不丢弃该第二目标fgMTN单元，仍然使用该fgMTN单元后面的内容(如开销、客户码块等)。
在出现开始码块码块类型域(block type field)错误的情况下，丢弃所述第二目标fgMTN单元；或者，在出现开始码块码块类型域错误的情况下，若所述目标码块是通过判断方式被确定为开始码块(例如根据其他信息推断目标码块为开始码块，如目标码块后面紧跟着的是数据码块)，读取所述第二目标fgMTN单元。也即，不丢弃该第二目标fgMTN单元，仍然使用该fgMTN单元后面的内容(如开销、客户码块等)。
二、所述目标码块包括数据码块。
在出现数据码块同步头(sync header)错误的情况下：
若所述数据码块携带fgMTN通道客户信息，将所述数据码块的64比特携带的一个或多个fgMTN通道的客户码块替换为错误码块；或者，若所述数据
码块携带开销信息，丢弃所述开销信息。
三、所述目标码块包括结束码块。
在出现结束码块同步头错误(sync header)或码块类型域(block type field)错误的情况下：
若所述结束码块携带fgMTN通道客户信息，将所述结束码块的64比特携带的一个fgMTN通道的客户码块替换为错误码块；或者，若所述结束码块携带开销信息，丢弃所述开销信息。
通过上述实施例的方案，提出了对fgMTN单元的不同类型的码块的异常处理方案，从而可保证异常情况处理的统一性，确保MTN网络的可靠性。
其中，图4所示的方法可单独实施，也可结合图1所示的实施例实施。
