Abstract：Current centralized restoration schemes are bad match for the increasing of the scale and complexity of networks. A novel distributed network partition scheme is 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.
