基于ASON的智能光网络及其控制平面

ASON-based Intelligent Optical Network and Its Control Plane

IP业务的爆炸性增长,对传送网络提出了更高的要求。智能自动交换光网络的出现是传送网概念的重大历史性突破。首先阐述了自动交换光网络的基本概念,然后对其控制平面的特点及功能要求、功能结构进行了详细讨论,最后介绍了自动交换光网络的信令机制和接口类型。

The explosive increase of IP service raised higher requirements for transport network.The emergence of intelligent Automatic Switched Optical Network(ASON)is an important his-torical breakthrough in the concepts of transport network.The basic concept of ASON is described firstly.Then fea-tures,functional requirements and func-tional structure of ASON control plane are discussed in detail.Finally,signaling mechanism and interface type of ASON are introduced.
