[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on January 2, 2024, with application number 202410011631.7 and invention name “64B / 66B coding block transmission method, electronic device and readable storage medium”. The entire contents of the application are incorporated by reference into this application. Technical Field

[0003] The embodiments of the present application relate to the field of communication technology, and in particular to a transmission method, electronic device, and readable storage medium for a 64B / 66B coding block. Background Art

[0004] The 64B / 66B encoding block is the most common encoding scheme in the Ethernet Physical Coding Sublayer (PCS). It is used to convert high-speed Media Access Control (MAC) frames into fixed-rate bit blocks while also adding necessary control information. The information transmitted by the 64B / 66B encoding block includes both data and control information. The data information primarily corresponds to the data in the MAC frame, while the control information includes special functions required for transmitting the MAC frame, such as indicating special states during MAC frame transmission. Special states include sending idle control information, local fault status (Local Fault) or remote fault status, and MAC frame header and trailer flags. When the rate of 64B / 66B code blocks is high, they are generally not transmitted directly. Instead, they are first transcoded into 256B / 257B code blocks, and then forward error correction (FEC) encoding information is added to the 256B / 257B code blocks before they are finally transmitted. Accordingly, after receiving this information, FEC decoding and error correction are first performed using the FEC algorithm to obtain 256B / 257B code blocks, which are then transcoded again to recover 64B / 66B code blocks.

[0005] In existing 64B / 66B coding blocks, the 64B / 66B coding blocks starting with the synchronization header 10 include 4 bits of redundant information in the type field. This allows the 64B / 66B coding blocks to be converted to 512B / 513B coding blocks at most, but cannot be converted to coding blocks with higher coding efficiency. Summary of the Invention

The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application.

[0015] Table 1.

[0016] FIG1 shows a flow chart of a method for transmitting a 64B / 66B coding block provided by an exemplary embodiment of the present application. Referring to FIG1 , the method may include the following steps.

[0017] Step 102: Obtain a 64B / 66B coded block to be transmitted. The 64B / 66B coded block includes a 2-bit synchronization header, the value of which is used to indicate whether the 64B / 66B coded block is a data 64B / 66B coded block or a first control 64B / 66B coded block. The first control 64B / 66B coded block also includes an 8-bit type field and a 56-bit information field. The value of the 8-bit type field is used to distinguish 11 different coding types.

[0018] The 64B / 66B coding block to be transmitted in the embodiment of the present application is used for the Ethernet physical coding sublayer (PCS) with a rate greater than or equal to 40G. The value of the 2-bit synchronization header of the 64B / 66B coding block can include 01 and 10. If the synchronization header is 01, the 64B / 66B coding block is a data 64B / 66B coding block. If the synchronization header is 10, the 64B / 66B coding block is a first control 64B / 66B coding block. The first control 64B / 66B coding block includes data information, control information and a type field. The content of the data information and control message can be determined by the type field.

[0019] Optionally, the control information may be multiple control characters, each containing 7 bits of information. Alternatively, the control information may be an ordered set control block (ORCS), each containing 28 bits of information. Control characters are used to represent relatively simple control information, while ORCS are used to represent relatively complex control information.

[0020] Step 104: Divide the first control 64B / 66B coding blocks of the 11 different coding types into coding blocks of the first group of coding types and coding blocks of the second group of coding types, convert the 8-bit type field in the coding blocks of the first group of coding types into an 8-bit first group of coding type field, and keep the 56-bit information field unchanged; convert the 8-bit type field in the coding blocks of the second group of coding types into a 9-bit second group of coding type field, and convert the 56-bit information field into a 55-bit information field.

[0021] The control information and data information of the first control 64B / 66B coding block are determined by the coding type of the first control 64B / 66B coding block. The coding type of the first control 64B / 66B coding block can be identified by an identifier represented by some bits in the 8-bit first group coding type field or the 9-bit second group coding type field.

[0022] Step 106: The 2-bit synchronization header, the 8-bit first group coding type field, and the 56-bit information field are combined into 66 bits of a second control 64B / 66B coding block; the 2-bit synchronization header, the 9-bit second group coding type field, and the 55-bit information field are combined into 66 bits of a third control 64B / 66B coding block.

[0023] Among them, according to the synchronization header, the first group of coding type fields or the second group of coding type fields, the 56-bit information field or the 55-bit information field, the 66 bits of the second control 64B / 66B coding block or the third control 64B / 66B coding block are composed, so that the coding type fields in the reconstructed second control 64B / 66B coding block and the third control 64B / 66B coding block can contain more bits of redundant bits, so that the reconstructed second control 64B / 66B coding block and the third control 64B / 66B coding block can be converted into coding blocks with higher coding efficiency, such as 1024B / 1025B coding blocks.

[0024] Step 108: Transmit the data 64B / 66B coded block, the second control 64B / 66B coded block, and the third control 64B / 66B coded block.

[0025] In an embodiment of the present application, for a 64B / 66B coded block to be transmitted, the value of the 2-bit synchronization header is used to determine whether the current 64B / 66B coded block is a data 64B / 66B coded block or a control 64B / 66B coded block. For example, 01 indicates that the 64B / 66B coded block is a data 64B / 66B coded block, and 10 indicates that the 64B / 66B coded block is a first control 64B / 66B coded block. For a data 64B / 66B coded block, the data 64B / 66B coded block includes 8 numeric characters, and 1 numeric character includes 8 bits of information. The data 64B / 66B coded block is not changed. For the first control 64B / 66B coding block, the first control 64B / 66B coding block includes an 8-bit type field and a 56-bit information field. The value of the 8-bit type field can be used to distinguish 11 different coding types, and then the first control 64B / 66B coding blocks of 11 different coding types can be divided into coding blocks of the first group of coding types and coding blocks of the second group of coding types. The 8-bit type field in the coding block of the first group of coding types is converted into an 8-bit first group of coding type fields, the 56-bit information field remains unchanged, and the 8-bit type field in the coding block of the second group of coding types is converted into a 9-bit The second group coding type field, in which the 56-bit information field is converted to a 55-bit information field, results in more redundant bits in the coding type field of the second control 64B / 66B coding block, which is composed of a 2-bit synchronization header, the 8-bit first group coding type field, and the 56-bit information field, and in the third control 64B / 66B coding block, which is composed of a 2-bit synchronization header, the 9-bit second group coding type field, and the 55-bit information field. These redundant bits can be deleted to free up bit space when the second and third control 64B / 66B coding blocks are converted to coding blocks with higher coding efficiency. This allows the data 64B / 66B coding blocks, the second control 64B / 66B coding blocks, and the third control 64B / 66B coding blocks to be converted to coding blocks with higher coding efficiency, such as 1024B / 1025B coding blocks, thereby improving transmission efficiency and leaving more rate for FEC coding information.

[0026] In one implementation, in the 64B / 66B coding block to be transmitted, the value of the 2-bit synchronization header is 01, indicating that the 64B / 66B coding block is the data 64B / 66B coding block; the value of the 2-bit synchronization header is 10, indicating that the 64B / 66B coding block is the first control 64B / 66B coding block; the 56-bit information field includes data characters, control characters, fixed information and information field redundant bits.

[0027] In an embodiment of the present application, the first control 64B / 66B coding block includes 66 bits of information, the first two bits of which are synchronization headers. A synchronization header of 01 indicates that the 64B / 66B coding block is the data 64B / 66B coding block, and a synchronization header of 10 indicates that the 64B / 66B coding block is the first control 64B / 66B coding block. The last 64 bits include an 8-bit type field for distinguishing 11 different coding types. The 11 different coding types can be divided into coding blocks of the first group of coding types and coding blocks of the second group of coding types. The remaining 56-bit information field may include data characters, control characters, fixed information, and information field redundancy bits.

[0028] In one implementation, in the first control 64B / 66B coding block, the 56-bit information field includes the data characters, the control characters, the fixed information and the information field redundant bits, wherein the data characters are 8 bits long and are represented by Dn, where n is a number from 1 to 8 and represents the order in which the data characters appear in the 56-bit information field; the control characters include two types, one of which is 7 bits long and is represented by Cm, where m is a number from 1 to 8 and represents the order in which the control characters appear in the 56-bit information field; the other type of control characters is 28 bits long and includes a 4-bit Q0 and three data characters D1, D2 and D3; the fixed information includes 28 bits of 0; and the information field redundant bits are bits in the 56-bit information field other than the data characters, the control characters and the fixed information.

[0029] In an embodiment of the present application, Table 2 shows a 64B / 66B coding block provided by an embodiment of the present application. Referring to Table 2, the block payload of a data 64B / 66B coding block with a synchronization header of 01 includes 8 data characters, where each data character includes 8 bits of information. A first control 64B / 66B coding block with a synchronization header of 10 includes 11 different coding types. The 11 different coding types can be divided into two groups, namely, a first coding type group and a second coding type group. The first coding type group includes 4 different coding types, and the second coding type group includes 7 different coding types. In the coding block of the first coding type group, the 4 different coding types are distinguished by an 8-bit first coding type field. In the coding block of the second coding type group, the 7 different coding types are distinguished by a 9-bit second coding type field. The 4 different coding types of the first coding type group are named a second control 64B / 66B coding block, and the 7 different coding types of the second coding type group are named a third control 64B / 66B coding block.

[0030] Table 2.

[0031] Table 2 shows the encoding information of a 64B / 66B coding block, including a 64B / 66B data coding block with a synchronization header of 01. The block payload of this 64B / 66B data coding block includes 8 numeric characters, each of which contains 8 bits of information, specifically "D0D1D2D3D4D5D6D7." Table 2 also includes a second control 64B / 66B coding block with a synchronization header of 10, including four different coding types. The block payload of this second control 64B / 66B coding block consists of an 8-bit first group coding type field and a 56-bit information field. The first bit of the 8-bit first group coding type field is 0, and the last two bits of the first three bits have different values, allowing the identification of four different coding types. The last five bits are redundant and can be deleted when converting to a more efficient coding block. The values ​​of the 8-bit first group coding type field are "0x1E", "0x78", "0x4B" and "0x2d", respectively. The first 3 bits are "000b", "011b", "010b" and "001b", respectively. The corresponding information fields are "C0C1C2C3C4C5C6C7", "S0D1D2D3D4D5D6D7", "Q0D1D2D3Z4Z5Z6Z7" and "D0D1D2D3D4D5D6T7", respectively. Among them, the 56-bit information field of the four different coding types in the first group of coding types does not contain information field redundancy bits.

[0032] Table 2 also includes a third control 64B / 66B coding block with a synchronization header of 10, including 7 different coding types. The block payload of the third control 64B / 66B coding block consists of a 9-bit group 2 coding type field and a 55-bit information field, wherein the first bit of the 9-bit group 2 coding type field is 1, and the last 3 bits of the first 4 bits have different values, which can be used to identify 7 different coding types. The last 5 bits can be deleted as redundant bits when it is necessary to convert to a more efficient coding block. The values ​​of the 9-bit second group code type field are "0x187", "0x133", "0x1AA", "0x155", "0x1CC", "0x166" and "0x1FF", respectively. The first 4 bits are "1100b", "1001b", "1101b", "1010b", "1110b", "1011b" and "1111b", respectively. The corresponding information fields are "T0C1C2C3C4C5C6C7" and "D0T1C2C3C4C5C6C7". , "D0D1T2C3C4C5C6C7", "D0D1D2T3C4C5C6C7", "D0D1D2D3T4C5C6C7", "D0D1D2D3D4T5C6C7" and "D0D1D2D3D4D5T6C7", where D represents a data character, C represents a control character with a length of 7 bits, Z represents 7 bits of 0, S represents the start of a coding block, T represents the end of a coding block, and Q0D1D2D3 together represent a control character with a length of 28 bits - an ordered set control block.

[0033] Optionally, for a 66-bit coding block, its first and second bits are defined as synchronization headers. On the premise that the synchronization header is 10 and it is determined to be the second control 64B / 66B coding block or the third control 64B / 66B coding block, it can be further determined whether it is the second control 64B / 66B coding block or the third control 64B / 66B coding block based on whether the third bit in the 66 bits is 0 or 1. If the third bit in the 66 bits is 0, then the 66-bit coding block is the second control 64B / 66B coding block. In this case, the coding type field length is 8 bits, corresponding to the third to tenth bits in the 66 bits. The first three bits in the 8-bit coding type field are valid bits and can be used to identify four different coding types. The last five bits are redundant bits in the type field and can be deleted when conversion to a more efficient coding block is required. If the 3rd bit in the 66 bits is 1, this 66-bit coding block is the third control 64B / 66B coding block. At this time, the coding type field length is 9 bits, corresponding to the 3rd to 11th bits in the 66 bits. The first 4 bits in the 9-bit coding type field are valid bits and can be used to identify 7 different coding types. The last 5 bits are redundant bits of the type field and can be deleted when conversion to a more efficient coding block is required.

[0034] In one implementation, all coding types in the coding blocks of the first group of coding types do not have the information field redundancy bits in the 56-bit information field; and all coding types in the coding blocks of the second group of coding types have the information field redundancy bits in the 56-bit information field.

[0035] In this embodiment of the present application, the 56-bit information field in the coding block of the first coding type does not include information field redundancy bits, which include data characters, control characters, and fixed information. When forming the second control 64B / 66B coding block, the 8-bit type field is converted into an 8-bit first group coding type field, and the 56-bit information field remains unchanged. The 8-bit type field is used to identify 11 different coding types and actually includes 4 bits of type field redundancy bits. The 8-bit first group coding type field obtained after conversion is used to identify 4 different coding types and actually includes 5 bits of type field redundancy bits. The 56-bit information field in the coding block of the second group of coding types includes data characters, control characters, fixed information and information field redundant bits. For the information field redundant bits, the preset bits of information field redundant bits are deleted when forming the third control 64B / 66B coding block, and the type field redundant bits are added to convert the original 8-bit type field and 56-bit information field into a 9-bit second group of coding type field and a 55-bit information field, so that the 8-bit first group of coding type fields and the 9-bit second group of coding type fields in the second control 64B / 66B coding block and the third control 64B / 66B coding block both contain 5 bits of type field redundant bits. Compared with the 4-bit type field redundant bits contained in the 8-bit type field in the first control 64B / 66B coding block, the coding type fields of the second control 64B / 66B coding block and the third control 64B / 66B coding block have 1 more bit of type field redundant bits.

[0036] In one implementation, the 8-bit first group coding type field includes a 3-bit control type identifier and a 5-bit type field redundant bit, wherein the 3-bit control type identifier is used to identify a coding blocks of different coding types in the coding blocks of the first group coding type, and a is a positive integer less than 7; the 9-bit second group coding type field includes a 4-bit control type identifier and the 5-bit type field redundant bit, wherein the 4-bit control type identifier is used to identify b coding blocks of different coding types in the coding blocks of the second group coding type, b=11-a.

[0037] In an embodiment of the present application, the 8-bit first group coding type field in the coding block of the converted first group coding type specifically includes a 3-bit control type identifier and a 5-bit type field redundant bit, and the 9-bit second group coding type field in the coding block of the converted second group coding type specifically includes a 4-bit control type identifier and a 5-bit type field redundant bit. There are 11 coding types in total. The first group coding type includes a, and the second group coding type includes (11-a). Both the first group coding type and the second group coding type identify different coding types through the control type identifier.

[0038] In one implementation, the value of the 3-bit control type identifier is a 3-bit value in a first value group, the first value group includes the a different 3-bit values, and the a different 3-bit values ​​are obtained by selecting from c different 3-bit values. Among them, the Indicates the Performing rounding. The value of the 4-bit control type identifier is a 4-bit value in a second value group, the second value group includes the b different 4-bit values, removing the a different 3-bit values ​​corresponding to the first value group from the c different 3-bit values ​​to obtain (ca) different 3-bit values, adding 1 bit to the (ca) different 3-bit values ​​to obtain 2*(ca) different 4-bit values, and selecting the b different 4-bit values ​​from the 2*(ca) different 4-bit values ​​as the second value group.

[0039] In an embodiment of the present application, different coding types are identified by different values ​​of bits in the control type identifier. From the c different 3-bit values, the a different 3-bit values ​​are selected as the first value group of the 3-bit control type identifier, which is used to identify the a different coding types in the coding blocks of the first group of coding types. From the c different 3-bit values, the a different 3-bit values ​​corresponding to the first value group are removed to obtain (ca) different 3-bit values, and 1 bit is added to the (ca) different 3-bit values ​​to obtain 2*(ca) different 4-bit values. From the 2*(ca) different 4-bit values, the b different 4-bit values ​​are selected as the second value group for identifying the b different coding types in the coding blocks of the second group of coding types.

[0040] In one implementation, the above-mentioned step 104 converts the 8-bit type field in the coding block of the first group coding type into an 8-bit first group coding type field, which may include the following steps.

[0041] Step 1041: Determine the specific type of the encoding type based on the value of the 8-bit type field.

[0042] Among them, the 8-bit type field has 11 different values, corresponding to 11 different encoding types. The 11 different values ​​of the 8-bit type field can be found in the type field-8 bits in Table 1, and the encoding formats of the 11 different encoding types can be found in the first control 64B / 66B encoding block format in Table 1.

[0043] Step 1042: Determine the value of the 3-bit control type identifier according to the specific type of the determined coding type.

[0044] Step 1043: Obtain the 8-bit first group coding type field according to the value of the 3-bit control type identifier and the 5-bit type field redundant bits.

[0045] Among them, the value of the 5-bit type field redundant bit can be all 0, or a specific value, so that the specific 8 bits of the a values ​​of the 8-bit first group of coding type fields and the b values ​​of the 9-bit second group of coding type fields have a Hamming distance greater than or equal to n, where n is an integer greater than or equal to 2.

[0046] In the embodiment of the present application, the first control 64B / 66B coding block includes 11 different coding types, which can be distinguished by coding formats. The specific coding formats of the 11 coding types can be found in the first control 64B / 66B coding block format in Table 1. The first group of coding types includes the a of the 11 different coding types, and the 56-bit information fields of the a coding types do not contain information field redundancy bits. For the first control 64B / 66B coding block, the specific coding type corresponding to the value can be determined according to the value of its 8-bit type field. If the determined coding type belongs to one of the a coding types in the first group of coding types, then this first control 64B / 66B coding block belongs to the coding block of the first group of coding types. Then, the value of the 3-bit control type identifier in the 8-bit first group of coding type field can be determined according to the determined coding type, and the 5-bit type field redundant bit is added to obtain a total of 8 bits. The 8 bits are used as the value of the 8-bit first group of coding type field, so that the second control 64B / 66B coding block can be obtained from the 8-bit first group of coding type field and the 56-bit information field.

[0047] In one implementation, the above-mentioned step 104 converts the 8-bit type field in the coding block of the second group coding type into a 9-bit second group coding type field, and converts the 56-bit information field into a 55-bit information field, which may include the following steps.

[0048] Step 1044: Determine the specific type of the encoding type based on the value of the 8-bit type field.

[0049] Among them, the 8-bit type field has 11 different values, corresponding to 11 different encoding types. The 11 different values ​​of the 8-bit type field can be found in the type field-8 bits in Table 1, and the encoding formats of the 11 different encoding types can be found in the first control 64B / 66B encoding block format in Table 1.

[0050] Step 1045: Determine the value of the 4-bit control type identifier according to the specific type of the determined coding type.

[0051] Step 1046: Obtain the 9-bit second group coding type field based on the value of the 4-bit control type identifier and the 5-bit type field redundant bits.

[0052] Among them, the value of the 5-bit type field redundant bit can be all 0, or a specific value, so that the specific 8 bits of the a values ​​of the 8-bit first group of coding type fields and the b values ​​of the 9-bit second group of coding type fields have a Hamming distance greater than or equal to n, where n is an integer greater than or equal to 2.

[0053] Step 1047: Delete 1 bit of the information field redundancy bit in the 56-bit information field to obtain the 55-bit information field.

[0054] The specific position of the deleted 1-bit information field redundant bit can use multiple rules. The rule can be the first appearing information field redundant bit, or the rule can also be to determine the specific position of the deleted 1-bit information field redundant bit for different coding types.

[0055] In the embodiment of the present application, the first control 64B / 66B coding block includes 11 different coding types, which can be distinguished by coding formats. The specific coding formats of the 11 coding types can be found in the first control 64B / 66B coding block format in Table 1. The second group of coding types includes the b of the 11 different coding types, and the 56-bit information fields of the b coding types contain at least one information field redundancy bit. For the first control 64B / 66B coding block, the specific coding type corresponding to the value can be determined according to the value of its 8-bit type field. If the determined coding type belongs to one of the b coding types in the second group of coding types, then this first control 64B / 66B coding block belongs to the coding block of the second group of coding types. Then, the value of the 4-bit control type identifier in the 9-bit second group of coding type field can be determined according to the determined coding type, and the 5-bit type field redundant bit is added to obtain a total of 9 bits. This 9 bit is used as the value of the bit second group of coding type field, and the 1-bit information field redundant bit in the 56-bit information field is deleted to obtain a 55-bit information field, so that the third control 64B / 66B coding block can be obtained from the 9-bit second group of coding type field and the 55-bit information field.

[0056] In one implementation, the above-mentioned step 108 of transmitting the data 64B / 66B coded block, the second control 64B / 66B coded block and the third control 64B / 66B coded block may include the following steps.

[0057] Step 1: Delete the 5-bit type field redundant bits in the second control 64B / 66B coding block and the third control 64B / 66B coding block.

[0058] Among them, the 5-bit type field redundancy bits in the second control 64B / 66B coding block and the third control 64B / 66B coding block are used to be deleted to release bit space when the 64B / 66B coding block needs to be converted into a coding block with higher coding efficiency.

[0059] Step 2: Convert 16 consecutive data 64B / 66B coding blocks, the second control 64B / 66B coding block, and the third control 64B / 66B coding block into one 1024B / 1025B coding block.

[0060] Step 3: Transmit the 1024B / 1025B coding block.

[0061] An embodiment of the above step 2 is as follows: In a 1024B / 1025B coding block, the first bit is 0, indicating that the next 1024 bits correspond to 16 data 64B / 66B coding blocks, and the first bit is 1, indicating that the 16 64B / 66B coding blocks corresponding to the next 1024 bits include at least one second control 64B / 66B coding block or a third control 64B / 66B coding block, wherein the first bit is 1 and the second bit is 0, indicating that 16 64B / 66B coding blocks corresponding to the next 1024 bits include at least one second control 64B / 66B coding block or a third control 64B / 66B coding block. There is only one second control 64B / 66B coding block or third control 64B / 66B coding block in the B coding block, and its position is determined by the values ​​of bits 3 to 6; if bit 1, bit 2, and bit 3 are 0, it means that there are two second control 64B / 66B coding blocks or third control 64B / 66B coding blocks in the 16 64B / 66B coding blocks, and the values ​​of bits 4 to 7 indicate the first second control 64B / 66B coding block. The position of the code block or the third control 64B / 66B code block, the values ​​of the 8th to 11th bits indicate the position of a second control 64B / 66B code block or the third control 64B / 66B code block at a later position; if the 1st bit is 1, the 2nd bit is 1, the 3rd bit is 1, and the 4th bit is 0, it means that there are 3 second control 64B / 66B code blocks or the third control 64B / 66B code blocks among the 16 64B / 66B code blocks, the values ​​of the 5th to 8th bits indicate the position of a second control 64B / 66B code block or the third control 64B / 66B code block at a earlier position, the values ​​of the 9th to 12th bits indicate the position of a second control 64B / 66B code block or the third control 64B / 66B code block at a second earlier position, and the values ​​of the 13th to 16th bits indicate the position of a second control 64B / 66B code block or the third control 64B / 66B code block at a third earlier position;The first bit is 1, the second bit is 1, the third bit is 1, and the fourth bit is 1, indicating that the 16 64B / 66B coding blocks have at least 4 second control 64B / 66B coding blocks or third control 64B / 66B coding blocks. Among the 16 bits from the 5th bit to the 20th bit, the 5th bit indicates the type of the first 64B / 66B coding block in the 16 64B / 66B coding blocks. If it is 0, it indicates that the first 64B / 66B coding block is a data 64B / 66B coding block. If it is 1, it indicates that the first 64B / 66B coding block is a second control 64B / 66B coding block or a third control 64B / 66B coding block. The 6th bit indicates the type of the first 64B / 66B coding block in the 16 64B / 66B coding blocks. The type of the second 64B / 66B coding block: 0 indicates that the second 64B / 66B coding block is a data 64B / 66B coding block; 1 indicates that the second 64B / 66B coding block is the second control 64B / 66B coding block or the third control 64B / 66B coding block; and so on. The 20th bit indicates the type of the 16th 64B / 66B coding block among the 16 64B / 66B coding blocks: 0 indicates that the 16th 64B / 66B coding block is a data 64B / 66B coding block; 1 indicates that the 16th 64B / 66B coding block is the second control 64B / 66B coding block or the third control 64B / 66B coding block. The 21st bit is fixed to 0. Based on the above bit definitions, 16 consecutive 64B / 66B code blocks can be represented by 1025 bits. Each 64B / 66B code block may be a data 64B / 66B code block, a second control 64B / 66B code block, or a third control 64B / 66B code block.

[0062] In one implementation, the above-mentioned 64B / 66B code block transmission method can be applied to a transmitting end of an electronic device, and the receiving end of the electronic device can perform the following steps.

[0063] Step 1: Receive 1024B / 1025B coded blocks.

[0064] Among them, for the transmitting end, the 1024B / 1025B coding block converted by the data 64B / 66B coding block, the second control 64B / 66B coding block and the third control 64B / 66B coding block can be transmitted; and for the receiving end, the 1024B / 1025B coding block transmitted by other transmitting ends can be received.

[0065] Step 2: Convert one 1024B / 1025B coding block into 16 data 64B / 66B coding blocks, the second control 64B / 66B coding block and the third control 64B / 66B coding block.

[0066] Step 3: Convert the second control 64B / 66B coding block and the third control 64B / 66B coding block into a first control 64B / 66B coding block.

[0067] In an embodiment of the present application, the receiving end receives a 1024B / 1025B coding block converted from a data 64B / 66B coding block, a second control 64B / 66B coding block, and a third control 64B / 66B coding block, and then converts the 1024B / 1025B coding block into 16 data 64B / 66B coding blocks, a second control 64B / 66B coding block, and a third control 64B / 66B coding block, and then converts the obtained second control 64B / 66B coding block and the third control 64B / 66B coding block into the initial first control 64B / 66B coding block to be transmitted, thereby realizing the conversion of the 64B / 66B coding block into a coding block with higher coding efficiency for transmission.

[0068] It should be noted that existing 10GE and 40GE Ethernet physical layer signals use 64B / 66B code blocks. For Ethernet physical layer signals at rates above 100GE, media access control frames are converted into 64B / 66B code blocks, which are then converted into 256B / 257B code blocks. FEC code blocks are then added to these 256B / 257B code blocks to form FEC code blocks, which are then transmitted at the physical layer. As Ethernet physical layer signal rates increase, such as to 1.6Tbps and above, it is likely that more efficient code blocks, such as 512B / 513B or 1024B / 1025B, will be needed compared to 256B / 257B code blocks. Through the method of the embodiment of the present application, 64B / 66B coding blocks can be converted into 1024B / 1025B coding blocks in a relatively simple manner, promoting the use of 1024B / 1025B coding blocks to replace 256B / 257B coding blocks in the future, thereby further reducing the rate of Ethernet physical layer signals.

[0069] In addition, the present application can also be used in an optical transport network (OTN) or a slicing packet network (SPN) to reduce the rate of 64B / 66B coded signals when transmitting 64B / 66B coded blocks. For example, G.709 stipulates that Fibre Channel-1200 (FC-1200) signals and 40GE signals also need to first convert 64B / 66B coded signals into 512B / 513B coded signals. The method of the present application can be used to convert 64B / 66B coded blocks into 1024B / 1025B coded blocks, thereby further reducing the rate of the converted coded blocks.
