Problems solved by technology

The uSID scheme uses a 16-bit common prefix and a 16-bit compression identifier. However, this scheme only discusses SRH compression, and does not explain how to realize the network programming function. function, its length is not enough, if it is increased to 32bit, a certain programming ability can be obtained (for example, 20bit is divided into locator in 32bit, and 12bit is function), but its programming ability is still relatively weak, and the compression efficiency is reduced
Another SRH compression scheme is a common compressed SID (C-SID) scheme (draft-li-spring-compressed-srv6-np-00), although it can provide flexible programmability while implementing SRH compression, However, its programmable capability is only provided at the tail node of the forwarding path, and cannot be provided at the intermediate node

Abstract

The invention provides a segment routing header compression method, which comprises the following steps: configuring a common compression segment identifier for each node on a segment routing path, and additionally configuring an extended compression segment identifier for at least part of nodes on the segment routing path, the extended compression segment identifier at least comprising a function field; generating a segment list comprising the common compression segment identifiers and the extended compression segment identifiers, wherein in the segment list, the extended compression segment identifier is adjacent to and located behind the common compression segment identifier of the node to which the extended compression segment identifier belongs; and carrying the segment list in a segment routing header of a service message. According to the embodiment of the invention, the extended compression segment identifier comprising the function field is used, the network programming capability of the node can be improved while the compression characteristic of the segment identifier is maintained, the node service function expansion is realized, and the wide applicability and flexibility of service processing are improved. The invention further provides a service processing method, a segment routing header compression device, a service processing device, computer equipment and a computer readable medium.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a segment routing header compression method, service processing method, device, computer equipment, and computer-readable medium. Background technique [0002] Segment routing (Segment Routing) is a technology to implement source routing. RFC8402 defines SR-MPLS based on MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) forwarding plane and IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) SRv6 on the forwarding plane Two standard SR mechanisms. With the exhaustion of IPv4 (Internet Protocol version 4, Internet Protocol version 4) addresses and the rapid development of the Internet of Things, more and more networks have deployed IPv6. SRv6 can be implemented directly based on the IPv6 extended routing header without adding additional encapsulation, realizing the unification of IP (Internet Protocol, Internet Interconn...
