Background
In a series of ethernet standards, data packets are used for communication between various devices in a network, data exchange, and the like. The data messages include management messages and service messages. Because the management packet and the service packet occupy the actual bandwidth of the ethernet during the transmission process, the ethernet carrying the management packet occupies the bandwidth of the ethernet port, which reduces the bandwidth of the service packet and affects the transmission rate of the service packet.
In the existing flexible ethernet (FlexE) technology, overhead code blocks are added in a transmission channel, which is used as a management channel and a dedicated channel for managing message transmission, thereby avoiding the situation that a management message contends for a channel with a service message.
At present, although the FlexE overhead code blocks can be used to carry management packets separately, the number of overhead code blocks dedicated to the management channel is limited, so that the bandwidth of the management channel is only 1.222 Mbps.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
Fig. 1 is a diagram illustrating flexible ethernet overhead insertion in the prior art.
According to the flexible ethernet in the prior art, as shown in fig. 1, for a flexible ethernet (FlexE) signal sequence, one overhead code block is inserted every 1023 × 20 blocks of 66B, and 8 overhead code blocks form one overhead frame. Overhead frame structure as shown in fig. 1, of the 8 overhead code blocks, 3 overhead code blocks from 6 th to 8 th are used for end-to-end management information between 2 ethernet underlayers.
Wherein, the 6 th overhead code block is used for carrying synchronization information in addition to carrying management information. Thus, only the 7 th and 8 th overhead code blocks dedicated to the management channel. Thus, the management channel from shim to shim is only about 1.222 Mbps. The network and the transmission network of the data of the operator basically adopt an intelligent management and control system, the intelligent management and control system needs to collect a large amount of data from the network equipment at the bottom layer for analysis and statistics, and sends a management control message to the underlying network equipment according to an analysis result to correspondingly control the underlying network equipment. Therefore, a large amount of management bandwidth is needed to transmit the management control messages between the underlying network devices. The bandwidth for transmitting these management control messages is much greater than 1.222 Mbps. In ethernet, to meet the actual networking and application requirements, the bandwidth of the management channel needs to be expanded.
In order to solve the above problem, in the present application, a newly-built physical sublayer is inserted between sublayers inside a flexible ethernet PCS layer, which is dedicated to processing management control packets, and can process multiple management control packets simultaneously, so as to expand the bandwidth of a management channel.

The newly created physical sublayer 102 is disposed between the FlexE underlayer 101 and the PCS underlayer 103.

Fig. 4B adds a newly-built physical sub-layer 102 as a management channel sub-layer (MCS) on the basis of fig. 1, and the newly-built physical sub-layer is arranged between the FlexE cushion layer and the PCS bottom layer and is used for processing a physical layer transport block transmitted by the FlexE cushion layer. The first network device writes the management control packet into the physical layer transmission block through the newly-built physical sublayer 102 to obtain a new transmission block, and transmits the second network device.
The PCS bottom layer may also transmit the physical layer transport block to the newly created physical sublayer 102, and after forming a new transport block, send the new transport block to the FlexE underlayer.
The second network device extracts the management control packet carried in the new transport block through the newly-built physical sub-layer 102, and sends the extracted management control packet to the application layer. The newly-built physical sublayer 102 is also used for recovering the new transport blocks into physical layer transport blocks, and transmitting the physical layer transport blocks to the PCS bottom layer or the FlexE underlayer.

The newly created physical sublayer 102 is disposed between the PCS upper layer 201 and the PCS lower layer 202.
Fig. 5B is a schematic diagram of a physical layer structure of a general ethernet transport packet processing protocol provided in the present application. On the basis of fig. 3 in the prior art, fig. 5B adds a newly-built network layer, and takes fig. 5A as an example, which shows a local physical layer structure in a general ethernet, and includes: a PCS upper layer, a MCS layer and a PCS bottom layer.
Wherein, the PCS upper layer and the PCS bottom layer are sublayers inside the ordinary Ethernet PCS layer. The new physical sublayer is an MCS layer arranged between the upper PCS layer and the bottom PCS layer.
The first network equipment writes the management control message into a physical layer transmission block through an MCS layer to obtain a new transmission block, and transmits the new transmission block to the second network equipment.
And the second network equipment extracts the management control message carried in the new transmission block through the MCS layer and sends the management control message to the application layer. The MCS layer is also used for recovering the new transport block into a physical layer transport block and transmitting the physical layer transport block to the PCS bottom layer or the PCS upper layer.
Based on the above provided local physical layer of the transmission message processing protocol, the following provides a transmission message transmission method, the core improvement of which is: and processing the management control message and the physical layer transmission block by utilizing the characteristic of the local physical layer of the transmission message processing protocol to obtain a new transmission block, wherein the new transmission block carries the management control message and is used for the transmission of the management control message. Fig. 6 is a flowchart illustrating a transmission packet transmission method according to an embodiment of the present application, where an execution main body of the method may be a network device, such as a switch, a router, and other devices, and all devices that need to manage channel bandwidth expansion may be extended by applying the method.
As shown in fig. 6, the transmission packet transmission method includes:
s301, the first network device obtains a management control message corresponding to the first application layer and a physical layer transmission block corresponding to the physical coding sublayer PCS through the first newly-built physical sublayer, and writes the management control message into the physical layer transmission block to obtain a new transmission block.
The first new physical sublayer is positioned between the first flexible Ethernet Flexe cushion layer and the first PCS bottom layer of the first PCS sublayer.
Since the interfaces of the physical coding sublayer PCS are simpler than other physical layer interfaces and involve fewer protocols, it is easier to convert the physical coding sublayer PCS from a physical layer transport block to a new transport block.
The management control messages can be written into the corresponding physical layer transmission blocks to obtain a plurality of new transmission blocks.
S302, the first network device sends the new transmission block to the second network device through the first newly-built physical sublayer.
And transmitting the new transmission block to the second network equipment, wherein the carried management control message can be used for controlling the second network equipment.
In this embodiment, the first network device writes the management control packet into a physical layer transport block transmitted between PCS sublayers to obtain a new transport block, and sends the new transport block to the second network device, and transmits the management control packet to the second network device through the new transport block, thereby completing transmission of the management packet without occupying bandwidth of a service data packet. The method can simultaneously convert a plurality of physical layer transmission blocks into a plurality of new transmission blocks to obtain a plurality of new transmission blocks carrying management control messages, thereby expanding the bandwidth of a management channel and meeting the bandwidth required by the transmission of the management messages.
Optionally, in the normal ethernet or flexible ethernet protocol, the physical layer transport blocks include a start control block and/or a spare block.
It should be noted that, in other protocols or after the current ordinary ethernet or flexible ethernet protocol is upgraded, the physical layer transport block is not limited to the start control block and the idle block, and may include more sub-blocks according to the transport requirement.
Taking the start control block field as an example, the start control block field table shown in table 1 is shown. As shown in table 1, the start control block may be a 66-bit field, where bits 2 to 9 are block type identification fields, the block type of the start control block is 0x78, and the 10 to 65-bit field is a data payload.
TABLE 1
The idle block is similar to the start control block except that the block type is 0x1E and the 10 to 65 fields are all 0.
Optionally, the first new physical sublayer may be an MCS layer. Taking transmission in the flexible ethernet as an example, the first network device obtains the management control packet and the physical layer transmission block corresponding to the physical coding sublayer PCS through the first newly-built physical sublayer, and writes the management control packet into the physical layer transmission block to obtain a new transmission block. The first flexible Ethernet Flexe cushion layer and the first PCS bottom layer are sublayers inside the flexible Ethernet PCS layer. The first new physical sublayer is located between the first flexible ethernet FlexE underlayer and the first PCS underlayer.
In the ordinary Ethernet, the upper PCS layer and the lower PCS layer are sublayers inside the ordinary Ethernet PCS layer. The newly built physical sublayer is positioned between the upper PCS layer and the lower PCS layer.
The first new physical sublayer makes the interface of the first flexible Ethernet Flexe cushion layer and the interface of the first PCS bottom layer completely consistent, acquires the management control message and the physical layer transmission block corresponding to the physical coding sublayer PCS, writes the management control message into the physical layer transmission block, and acquires the new transmission block inside the new physical sublayer, so that the first flexible Ethernet Flexe cushion layer and the first PCS bottom layer cannot sense the operation inside the first new physical sublayer, and the transmission of the physical layer transmission block inside the PCS layer is not influenced.
The first new physical sublayer can write the management control messages into a plurality of initial control blocks and idle blocks at the same time. The greater the number of start control blocks and free blocks used for writing, the greater the bandwidth of the management channel.
Further, the new transport block includes: and the indicating bit is used for indicating that the new transmission block is obtained by writing the initial control block or the idle block into the management control message.
Wherein, according to the indication bit, it can be determined that the new transmission block is obtained by writing the management control message into the initial control block or the idle block. For example, an indication bit of 0001 may indicate that a new transport block is obtained by writing the management control packet into the initial control block, and an indication bit of 0011 may indicate that a new transport block is obtained by writing the management control packet into the idle block.
Writing the management control message into a physical layer transmission block to obtain a new transmission block, wherein the field of the new transmission block is shown in table 2:
TABLE 2
Since the new transport block is from the physical layer transport block write management control packet, the bytes of the new transport block are the same as the bytes of the physical layer transport block. If the new transport block is from the management control packet written in the field of the start control block shown in table 1, the field length of the obtained new transport block is identical to the field length of the start control block shown in table 1, and is a 66-bit field. Wherein, the fields 2 to 9 are block type identifiers, the block type identifiers of the new transmission blocks are unchanged, the fields 10 to 13 are indication bits, the fields 14 to 17 are reserved fields, and the fields 18 to 65 are payload parts of the management control messages.
The new transmission block receives different types of data blocks transmitted by a first Flexe underlayer and/or a first PCS bottom layer of the physical layer transmission block, obtains type identifications of the different types of data blocks, searches the type identification corresponding to the management data block from the obtained type identifications, determines the data block corresponding to the type identification as a physical layer data block, and writes the management control message into the determined physical layer data block.
According to a transmission message transmitting method provided in an embodiment of fig. 6, the present application provides a transmission message receiving method, which is used to receive a message transmitted in the embodiment of fig. 6, fig. 7 is a schematic flow diagram of the transmission message receiving method provided in an embodiment of the present application, an execution main body of the method may be a network device, such as a switch, a router, and other devices, and any device that needs to perform bandwidth extension of a management channel may be extended by applying the method, as shown in fig. 7, the transmission message receiving method includes:

And the second newly-built physical sublayer is positioned between a sublayer of a second PCS of the second network equipment, a second flexible Ethernet Flexe underlayer and a second PCS bottom layer.
And the second network equipment receives the new transmission block sent by the first network equipment.
S402, the second network device extracts the management control message carried in the new transmission block through the second newly-built physical sub-layer and sends the management control message to the second application layer.
And S403, the second network device replaces the new transport block with the physical layer transport block through the second newly-built physical sublayer.
Alternatively, the fields of the new transport block are shown in table 2, the fields of the physical layer transport block are shown in table 1, the new transport block is replaced by the physical layer transport block, and the conversion from the fields shown in table 2 to the fields shown in table 1 is completed.
And S404, the second network device sends the physical layer transmission block to a second flexible Ethernet Flexe cushion layer or a second PCS bottom layer through the second newly-built physical sublayer.
Similarly, when the second network device needs to send the management packet to the first network device, the second network device obtains a new transport block through the second newly-built physical sub-layer, and sends the new transport block to the first network device. And the first network equipment acquires a new transmission block through the first newly-built physical sub-layer and acquires the management control message in the new transmission block.

s403a, according to the indication bit of the new transport block, the second network device replaces the new transport block with the start control block or the idle block through the second new physical sublayer.
For example, the new transport block indication bit is 0001, and the new transport block is restored to the starting control block; the new transport block indicator bit is 0011, and the new transport block is restored to an idle block.
S403b, the second network device sends the start control block or the idle block to the second flexible ethernet FlexE underlayer or the second PCS underlayer through the second newly-built physical sublayer.
Optionally, the replaced initial control block or spare block may be sent to the first network device through the second network device, and used for writing the next management control packet. Or the management control message may be rewritten in the second network device to form a new transport block.
Because the second newly-built physical sublayer makes the interface of the second flexible ethernet FlexE underlayer and the interface of the second PCS bottom layer completely consistent, the first flexible ethernet FlexE underlayer and the first PCS bottom layer cannot sense the operation of acquiring the management control packet in the second newly-built physical sublayer and replacing the new transmission block with the physical layer transmission block, so that the transmission of the physical layer transmission block in the PCS layer is not affected.
