摘要
为适应网络扁平化发展趋势的需求,运营商明确提出吉比特无缘光网络(GPON)光线路终端(OLT)要向汇聚型OLT发展,使其同时具有汇聚交换机和边缘设备的接入功能。针对此需求,对GPON系统及路由信息协议(RIP)进行深入研究,提出一种在GPON OLT上实现RIP协议的方法,该方法实现了GPON OLT的三层路由功能,使OLT工作在网络层,精简了宽带网络层次,增强了网络可靠性。
As networks tend to be flattened,a direction has been pointed out by telecommunication operators that Optical Line Terminals(OLTs) of Gigabit-Capable Passive Optical Network(GPON) should become aggregation OLTs,which enables them to work as both aggregation switches and edge-access-devices.According to this requiment,a solution that realizes Routing Information Protocol(RIP) on OLTs of GPON is issued after deep analyses of GPON system and RIP.As a result,the IP routing on OLTs of GPON is realized,which allows OLTs to work on the network layer.Addtionally,the broadband network levels are simplified,and the reliability of the network is increased.
