城域网间异厂家跨域SRv6实践

新一代网络传送技术Segment Routing设计了两种数据平面,其中一种为SRv6,使用IPv6数据平面,它结合了IPv6和SR两者的优势。未来5G和云时代的业务承载需求要求IP网全面具备SRv6的能力。然而现阶段SRv6仍处于标准化制定中,主流厂家实现上有较大差异,导致运营商混合组网的架构难以进行规模部署。为此,广东联通网络运营部积极学习SRv6底层原理,多次开展技术交流,并完成业界首个跨运营商骨干网、跨厂家SRv6互通的L3VPNv4测试,此次测试的成功也标志着中国联通开启了智能承载网SRv6的新时代。

Cross domain srv6 practice of different manufacturers in man

The new generation network transmission technology segment routing has designed two data planes,one of which is srv6.It uses IPv6 data plane,which combines the advantages of IPv6 and Sr.In the future 5G and cloud era,the service bearing requirements require that the IP network has the ability of srv6.However,srv6 is still in the process of standardization at this stage,and there are great differences in the implementation of mainstream manufacturers,which makes it difficult for operators to deploy the scale of mixed networking architecture.For this reason,Guangdong Unicom network operation department actively studied the underlying principle of srv6,carried out technical exchanges for many times,and completed the industry’s first l3vpnv4 test of cross operator backbone network and cross manufacturer srv6 interworking.The success of this test also marks that China Unicom has opened a new era of intelligent bearer network srv6.
