摘要
决定GPON系统的规模、性能、接入能力等因素很多,其中VLAN资源的规划及分配方式潜在地制约着GPON网络的可扩展性以及和数据城域网的连接能力。本文着重阐述GPON网络中VLAN资源的重要性和作用,并讨论在FTTH规模应用中对VLAN资源分配带来的挑战。基于上述讨论,文章提出一种优化的VLAN资源分配方式,该方式能够在原有FTTB模式的基础上平滑过渡至FTTH模式,对支撑FTTH业务开展提供一种应用建议。
Among the main factors affecting PON network scale,performance,access capacity and etc.,VLAN resources potentially limits on the network scalability and connection capacities to metro-Ethernet.This paper focuses on the importance and function of VLAN in PON network,furthermore discusses the challenge of VLAN apportionment in FTTH mode deployment.Finally,an optimized VLAN allocation strategy is suggested,which can realize the smooth conversion of VLAN resources allocation.
