自动交换光网络控制平面管理方案的分析和设计

自动交换光网络(ASON)作为智能光网络的典型代表,集中体现了下一代光网络向着智能化、大容量发展的方向。ASON网络中由于控制平面的引入,在为其带来了快速连接建立、自动资源发现等诸多特色功能的同时,也对这种新型网络的管理提出了新的挑战。如何通过对核心控制层面的管理保证网络的正常运行成为人们目前迫切希望得到解决的问题之一。我们首先讨论了控制平面的管理需求,并相应提出了针对控制平面的管理功能。最后,在此基础上,我们建立了具有层次清晰、功能明确等特点的控制平面网络和网元管理信息模型,从而形成了一种新的针对ASON控制平面的管理方案。

Analysis and Design of Management Scheme for Automatically Switched Optical Network

ASON, asa typical presentation of intelligent optical network , is walking toward the intelligent and larger-capacity tendency of the next generation optical network. The introduction of control plane (CP) brin gs not only many remarkable functions, such as fast establishment of connection and automatically resource discovery, but also some new chal lenges for network management. How to manage the control plane becomes an ur gent problem for people. In thispaper, we firstly analyze the requirements of CP management, then present the management functions required. In t he following, we set up the network level and network element level ma nagement information models, which have the characteristics of level-distin ct and function-oriented. Thusa kind of new management sche-me of control pla ne isformed.
