光网络中的路由信息交换

Routing Information Exchange in Optical Networks

分析了IP路由路和核心光网络之间 ,光子网内部以及光子网之间的路由信息交换。这种路由信息交换在自动建立穿越多个光子网的端到端光通道的过程中是非常重要的。UNI路由信息交换 ,分为三种类型 ,并对部分对等模型和完全对等模型做了详细分析 ,此外 ,对NNI路由信息交换以及端到端的光通道动态供给模型也做了粗略分析。

In this paper,routing information exchange between IP clients and core optical networks,and between optical sub-networks is analyzed in detail.Such information exchange will play a vital role in the establishment of end-to-end paths in an optical network comprising of multiple sub-networks.The UNI routing information exchange is divided into three types,and partial peer model as well as full peer model are discussed in detail.Furthermore,NNI routing information exchange and end-to-end path provisining model are also analyzed.
