摘要:

数字化、智能化承载网络成为网络建设与运营的主要目标,承载协议作为实现网络互联与业务承载的关键技术,直接决定了网络规模部署能力与业务承载效率。面向一致性体验与差异化融合承载需求,IPv6段路由(IPv6-based segment routing,SRv6)作为IPv6演进的关键技术,成为未来网络承载协议的发展方向。基于SRv6技术原理,剖析了SRv6头压缩需求,并结合业界典型的SRv6头压缩方案分析了各方案的优劣,为SRv6技术规模部署提供指引。

关键词: SRv6, 头压缩, 承载协议

Abstract:

Digital and intelligent carrier network have become the priorities of network construction and operation.As a key technology to realize network interconnection and service carrying, carrier protocol critically decides the network scale and traffic efficiency.Facing the service consistent experience requirements, SRv6 as the most competitive technology of IPv6 evolution, has become the development direction in the future.Combined with the principle of SRv6 technology, the requirements of SRv6 compression were analyzed.Based on the main SRv6 compression schemes in the industry, the advantages and disadvantages of each scheme were analyzed, so as to provide guidance for the large scale deployment of SRv6 technology.

Key words: SRv6, header compression, carrier protocol
