自动交换光网络的分布式连接管理技术

The Distributed Call and Connection Management in Automatically Switched Optical Network

自动交换光网络已经成为下一代光网络的发展方向,而其控制平面的分布式连接管理功能则是实现光网络智能性的关键。介绍了自动交换光网络的功能结构,在此基础上系统论述了分布式连接管理的功能要求,详细分析了分布式的呼叫和连接处理的实现过程,并给出了具体的参考流程和状态转移模型。

Automatic al ly Switched Optical Network (ASON) is regarded as the model of the next generati on optical network , and the distributed call and connection management (DCM) o f control plane in ASON is the key to the intelligent optical network . This pa per introduces the architecture of ASON and focuses on the mechanism of DCM , s hows the procedure of DCM in detail and also provides the reference model of state transfer and flows.
