摘 要: 智能光网络与传统光网的根本区别就在于明确的提出了控制平面的概念。其中网络拓扑(节点和连接)及其可用资源是网络操作的基础。理想状态下,网络拓扑和资源应该是自动发现的,这就要求邻居发现以及在整个网络进行信息发布的机制。此外,智能光网络的边缘节点应该具有业务发现能力,从而在以UNI接口模型实现的网络互联中,UNI-C指示客户设备能力且从UNI-N获取跟传送网络业务能力有关的信息。 The main difference between the intelligence optical networks and the traditional optical networks is the introduction of the concept of control plane. Network topology made up of nodes and links as well as usable resources is the background of network operation. Ideally, network topology and resources should be discovered automatically, which requires automatic neighbor discovery and message advertisement mechanisms in the entire network. Furthermore, the edge nodes of the intelligence networks are bound to have the capability of service discovery. At the boundary of the networks that realize connection based on UNI model, UNI-C indicates the capability of client equipment to UNI-N and gets information about service capability of transport network from UNI-N as well.
