自动交换光网络网管系统的设计与分析

自动交换光网络（ASON）在光传输网络之上引入控制平面，可以支持动态波长连接的建立，动态地分配网络资源，因此一出现就引起了广泛的关注。ITU－T等组织定义了大量关于控制信令方面的规范，但是没有给出任何与网络管理方面相关的内容。本文针对ASON网络的特点，提出了适合ASON网络的基于CORBA技术实现的域间网络管理方案，然后对ASON的基本管理功能需求进行了分析，其中着重分析了ASON引入的控制平面的管理需求，为控制平面管理功能的实现做出了理论指导。最后，对如何应用CORBA技术实现网管系统进行了分析。

The Architecture Design and Analysis for ASON Network Management System

The automatic switched optical networks (ASON) introduces a control plane above the optical transport networks, which could create the optical network connection and allocate the network resources dynamically. Many organizations such as ITU-T have given a lot of criterions about control signaling, none of them are about the management system. An architecture for ASON network management system was proposed in this paper, which using CORBA to realize an inter-domain management. Then the management requirement for ASON was analyzed, especially for the control plane which was introduced by ASON. At last, this paper provides a function diagram for inter-domain network management system, and analyses the implement of using CORBA in ASON network management system.
