A data transmission method, communication device and storage medium

Abstract

The embodiment of the present application provides a data transmission method, communication equipment and storage medium, which are used to reduce the number of cross-connections of intermediate nodes in the network. In the embodiment of the present application, the obtained Q first code block streams are multiplexed into a second code The code block stream is transmitted, and the encoding type of the first code block stream is M1 / N1 bit encoding, the encoding type of the second code block stream is M2 / N2 bit encoding, and the corresponding bits of the code blocks in the first code block stream of Q pieces are carried In the payload area of ​​the code block in the second code block stream, that is to say, the solution provided by the embodiment of the present application multiplexes and demultiplexes the code block stream at the granularity of the code block, so that the second code block The stream passes through at least one intermediate node to reach the communication device on the demultiplexing side, and the intermediate node does not demultiplex the second code block stream, thereby reducing the number of cross-connections of intermediate nodes in the network.

Description

technical field [0001] The present application relates to the communication field, and in particular to a data transmission method, communication equipment and storage medium. Background technique [0002] The Optical Internet Forum (OIF) released Flexible Ethernet (FlexibleEthernet, FlexE), which is a general technology supporting multiple Ethernet MAC layer rates. By binding multiple 100GE (Physical, PHYs) ports and dividing each 100GE port into 20 time slots in the time domain with 5G as the granularity, FlexE can support the following functions: bonding, multiple Ethernet ports Bundled as a link group to support Medium Access Control (MAC) services with a rate greater than that of a single Ethernet port; sub-rates, by assigning time slots to services to support rates lower than the link group bandwidth or lower than a single Ethernet port Broadband MAC services; channelization, by allocating time slots for services to support the simultaneous transmission of multiple MA...

Problems solved by technology

image 3 It exemplarily shows a communication schematic diagram of end-to-end networking where X-Ethernet flat networking technology is applied to metropolitan area and backbone network. There are tens of thousands of dedicated line services between multiple cities that need to be dispatched, and the aggregation node (like image 3 Aggregation shown) and backbone nodes (such as image 3 The backbone shown) has to manage hundreds of thousands or millions of end-to-end cross-connections, and there are difficulties in management and operation and maintenance. Each core node (such as the aggregation node and backbone node) handles huge cross-connections on the data plane Quantities, difficulties and stress
