基于GPON的多业务承载系统研究

随着IPTV、手机电视等IP以太网基础上的多业务的需求越来越大,电信运营商面临各自的接入网在＂三网融合＂形势下的新挑战和新机遇。目前的基于铜缆宽带接入网虽然能够提供基于互联网的视频,但距离真正大规模三网融合业务的运营仍存在较大差距。通过对GPON光网络架构分析,给出了多业务承载网络的QoS功能的实现,并实现端到端QoS质量的保证,通过测试验证了方案的可行性,最后针对国内某省电信运营商GPON试点局建网分析和研究,探索出一套满足电信运营商的三网融合方案。

Study of multi-service bearing system based on GPON access network

With IPTV,SMMB and other IP Ethernet based on the bump up for multi-service,the telecom operation is facing the integration of Access network,NGB network and mobile access network to increase the AIP.But it is difficulty for the operator to maintenance the multi-service on the copper access network,especially to achieve the copper system on video business expansion,thus affecting the whole business of access.It is critical point for how to setup and improve the GPON access network of a new research direction.This paper presents an solution of GPON technology,giving the overview of network,the multi-services like data services,voice,video data is loaded with different programs,ensuring the QoS from end to end.By such solution,it could be the golden model for the domestic operators to expand their services to the end-users.
