Problems solved by technology

[0004] Research and practice have found that the existing technology is mainly aimed at the scenario of a single source to multiple receiving points, but in the actual network there are more scenarios of multiple sources to multiple receiving points, which makes the existing technology unable to meet the requirements of the actual network. Application needs, and the existing technology adopts the mechanism of split coding, which greatly increases the data processing load of network nodes

Abstract

Disclosed in the embodiment of the present invention are a method for coding thereof related device and communication system. In the embodiment of the present invention, DNCP(DNCP: Doublesource Network Coding Protocol) is provided for supporting coding and decoding between two signal sources, wherein, the coding device performs random linear coding to two IP packages whose arrival interval are smaller than the setting duration and the destination addresses are same, through this ,it is useful for partly eliminating the influence of mismatch of transmitting rate and transfer delay in the actual network; at the same time, the header of DNCP package carries two source IDs, two IP package IDs and coding coefficient vector information which is related to the coding coefficient vector, which lays the foundation for the coding device continuously to code multi times or for the decoding device to decode rapidly, and benefits improving the generality of network coding in the actual network; and as the present invention is carried out based on network coding technology, therefore it can make full use of network resource and increase the network throughout rate obviously and achieve higher transmission efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a codec method, related equipment and a communication system. Background technique [0002] Network Coding (NC, Network Coding), which was born in 2000, proposed how to achieve the network communication capacity determined by the "maximum flow minimum cut theorem" when a single source or multiple sources multicast or broadcast to multiple receiving points in a communication network An idea of ​​the limit. [0003] Routing switches on traditional communication network nodes only complete the "store-and-forward" function, and regard information as "goods", so they believe that information cannot be superimposed. And this cognitive limitation makes it difficult for the network to achieve maximum flow transmission. NC pointed out that if the routing switch is allowed to encode multiple incoming information streams before sending them, the network communication can ach...
