Abstract

The invention discloses a message transmission method, a proxy node and a storage medium, and belongs to the technical field of communication. In the message transmission method, a new SID with a bypassing function is expanded for an End.AD.SID, when a local agent node receives a message carrying the End.AD.SID, the new SID is utilized to transmit the SRH of the message to an agent node at an opposite end in a bypassing manner, so that the agent node at the opposite end can further obtain the SRH of the message, and the SRH of the message can be stored in the agent node at the opposite end; and the synchronization of the SRH of the message can be realized between the two proxy nodes which are accessed to the same SF node in a dual-homing manner, so that the SRH of the message obtains redundant backup.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a message transmission method, a proxy node and a storage medium. Background technique [0002] Segment routing (English: segment routing, referred to as: SR) is a technology based on the concept of source routing to forward packets. SRv6) is a technology that combines the SR technology with the IPv6 protocol. Specifically, the SRv6 message will carry a segment routing header (English: segment routing header, SRH for short) on the basis of carrying an IPv6 header (English: IPv6 header). The SRH includes segment identification (English: segment ID, abbreviated: SID, also called segment) list (English: SID list, also called segment list) and the number of remaining segments (English: segment left, abbreviated: SL) and other information. The segment list contains one or more sequentially arranged SIDs, each SID is a 128-bit IPv6 address in form, and each SID ca...
