摘要

SRv6作为新一代IP网络核心技术，逐步成为5G和云时代的网络演进方向。如何解决头部开销过大、承载效率低、现网升级难的问题，使SRv6可实际商用部署，已经成为业界关注的焦点。基于这一技术难题，首先提出头压缩设计需求，包括：兼容标准SRv6头部封装，继承标准SRv6和IPv6优势，兼容当前网络地址规划，达成压缩效率与处理性能的有效平衡，与现有网络互联互通；其次，提出基于公共前缀拼接的G-SID头压缩方案，定义G-SID Container、COC Flavor、SI的关键技术能力，并提出压缩和非压缩网络混合部署的网络编排方式；最后，介绍G-SID方案在业界国际标准的进展，通过多厂商设备互通验证可行，并计划现网试点部署，推进SRv6全网快速落地。

Abstract

As the key technology of the new generation IP network

SRv6 has gradually become the direction of network evolution in the 5G and cloud networks.The problems how to solve the problems of excessive head overhead

low payload efficiency

and difficult upgrading from the existing network has become the focus of the industry.Based on this technical problem

header compression design principles were proposed firstly

including mechanism compatible with standard SRv6 header encapsulation

inheriting the advantages of standard SRv6 and IPv6

compatible with existing network address plan

achieving an effective balance of compression efficiency and processing performance

and interconnecting with existing networks.Secondly

a G-SID header compression solution was proposed based on common prefix stitching

the key technical capabilities of G-SID container

COC flavor

and SID index were defined

and a network orchestration solution for mixed deployment of compressed and uncompressed networks was proposed.Finally

the progress of the G-SID solution in the industry’s international standards was introduced

and has been verified by the interoperability of multi-vendor equipment

and the pilot deployment on the existing network was planned to promote the rapid deployment of SRv6 on the entire network.
