A Network Partition Scheme for Restoration in Optical Networks
一种用于光网络故障恢复的网络分割策略

Current centralized restoration schemes are networks. A novel distributed network partition scheme is bad match for the increasing of the scale and complexity of proposed in this paper. A large-scale network can be partitioned into several annular sub-networks with nuclear nodes in this scheme. In each sub-network, distributed manage ment and distributed restoration is adopted. The detailed process of partition is provided and the relevant distributed restoration scheme is given. Finally, this scheme has been implemented through computer simulation, and it was tested on practical optical networks. The simulation results show that this scheme is practicable and effectual.
