摘　　要：江苏作为国内较早发展IPTV的省份,其用户规模位于全国前列。自2017年IPTV业务平台与CDN解耦,采用一套统一EPG平台对接多个CDN。全省用户均在一套平台承载,这对平台的稳定性、健壮性提出极大挑战。为提升平台高可用性,我省持续对IPTV平台进行架构优化方案研究,从双中心主备,到双中心双活,再到多中心多活,历经多个架构方案及现网实践,逐步形成多中心多活架构,实现了灵活高可用。本文介绍了IPTV平台多中心架构的目标、实现方案、关键技术与实施效果。As one of the earliest provinces in China to develop IPTV,China telecom Jiangsu Branch has a leading user scale nationwide.Since 2017,when the IPTV platform was decoupled from CDN,a unified EPG platform was connected to multiple CDNs,and all users in the province were carried on a single platform,which poses great challenges to the stability,robustness.To enhance the high availability of the platform,we have been continuously researching on the architecture optimization plan.From dual-center primary and backup to dual-center dual-active,and then to multi-center multi-active,after going through multiple architecture solutions and current network practices,a multi-center multi-active architecture was gradually formed,achievingflexible high availability.This paper introduces the goals,implementation plans,key technologies and implementation effects of the multi-center architecture of the IPTV platform.
