Problems solved by technology

However, most of the existing header compression schemes are to extract the common prefix. When this compression method is used in the same domain, the compression efficiency is very high, but when it involves cross-domain or across multiple domains, this method of extracting the common prefix The compression scheme, its compression efficiency is greatly reduced

Abstract

The invention provides a message forwarding method and system and a storage medium. The method comprises the following steps: adding information of all forwarding domains passed by a message forwarding path and first routing forwarding information reaching a next forwarding domain into a Segment List at a source node; and when the forwarding domain head node receives the message, the forwarding domain head node adding the second routing forwarding information to the segment List, and deleting the forwarding domain information of the forwarding domain where the forwarding domain head node is located and the routing forwarding information of the previous forwarding domain from the segment List. According to the method, the system and the storage medium disclosed by the invention, the forwarding path can be segmented and compressed under the cross-multi-domain long forwarding path, the SRH length in cross-multi-domain transmission is reduced, message simplification can be realized, and the message bearing efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message forwarding method, system and storage medium. Background technique [0002] SR (Segment Routing, segment routing) v6 technology realizes flexible and programmable network by inserting SRH (Segment Routing Header, segment routing header) in the IPv6 packet header. But at the same time, as the number of SID (Segment Identifier, segment identifier) ​​layers in the SRH increases, the carrying efficiency of the message will decrease, and the network burden will increase. In order to solve this problem, the industry has proposed header compression schemes such as G-SRv6 and uSID, which have greatly improved the compression efficiency. However, most of the existing header compression schemes are to extract the common prefix. When this compression method is used in the same domain, the compression efficiency is very high, but when it involves cross-domain or mul...
