摘要
随着IPRAN(IP无线接入网)的测试和应用,对于双节点跨环进行环间保护并且使用MS-PW(多段伪线)和DNI(双归属)保护的全二层PWE3(端到端的伪线仿真)或者L2VPN(二层虚拟专网)转L3VPN(三层虚拟专网)业务的复杂应用场景,采用常规配置方式过程非常复杂。文章介绍了IPRAN在上述场景中复杂的配置步骤,提出用业务场景模板方法进行关键节点映射替换,将业务需要的隧道、PW、PW冗余和DNI保护等都纳入业务配置过程中,一次性快速完成,从而解决这种场景中端到端静态业务配置的效率问题。
With the tests and applications of IP Radio Access Networks （IPRAN）,there emerge many complex application scenes,e.g.full layer2 PWE3 for inter-ring protection of double node cross-ring service and using MS-PW and DNI protection or L2VPN transferred to L3VPN service.For these scenes,the conventional configurations are very complicated in modes and process.This paper introduces the complicated configuration steps of IPRAN in the above-mentioned scenes and presents the mapping substitution of the key nodes with a service scene template,incorporating all the tunnel,PW,PW redundancy and DNI that are required by the services rapidly once for all and thus improving the efficiency of E2E static service assignment in such scenes.
