Embodiment Construction
[0033] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.
[0034] figure 1 Insert schematic diagram for flexible Ethernet overhead in prior art.
[0035] According to the flexible Ethernet in the prior art, such as figure 1 As shown, for a Flexible Ethernet (FlexE) signal sequence, an overhead code block is inserted every 1023*20 66B blocks, and 8 overhead code blocks form an overhead frame. Overhead frame structure such as figure 1 As shown, among the 8 overhead code blocks, the 6th to 8th overhead code blocks are used for the end-to-end management information between the two Ethernet cushion layers.

The invention provides a transmission message transmission method, a receiving method and a processing device, and relates to the field of communication. The transmission message transmission method comprises the following steps: a first network device obtains a management control message corresponding to a first application layer and a physical layer transmission block corresponding to a physicalcoding sublayer PCS through a first newly built physical sublayer, and writes the management control message into the physical layer transmission block to obtain a new transmission block; Wherein thefirst newly built physical sub-layer is located between the first flexible Ethernet FlexE cushion layer of the sub-layer of the first PCS and the first PCS bottom layer; And the first network devicesends the new transmission block to the second network device through the first newly built physical sub-layer. a plurality of management control messages can be written into specified positions in the corresponding physical layer transmission blocks at the same time, and a plurality of new transmission blocks are obtained to be used for transmitting the management messages, so that the bandwidthof a management channel can be improved, and the sending and receiving of the management control messages can be completed on the basis of not occupying the bandwidth corresponding to the service datamessages.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a transmission message transmission method, a receiving method and a processing device. Background technique [0002] In a series of Ethernet technical standards, data packets are used for the connection of various devices in the network and the exchange of data. Data packets include management packets and service packets. Since the management packets and service packets occupy the actual bandwidth of the Ethernet during transmission, the bandwidth of the Ethernet port occupied by the management packets carried by the Ethernet reduces the bandwidth of the service packets and affects the transmission rate of the service packets. . [0003] In the existing Flexible Ethernet (FlexE) technology, an overhead code block is added to the transmission channel as a management channel, which is used as a dedicated channel for the transmission of management messages, thus avoiding the ch...
