Network Survivability Management System Design for Broadband Networks

In order to improve the network management ability, an important issue is to design a network survivability management system as an independent function. This paper proposes new structure to preplan and download different response procedures for every network element at different layers, according to overall information of the network. Cooperation among different restoration techniques in different layers is performed by a hybrid escalation mechanism, which is based on the sequential activation of different restoration techniques. General rules and timing issues are also discussed in detail. The design is based on multi-agent framework and describes the cooperation methods for multi-agent system considering the characteristics of network management function
