一种用于光网络故障恢复的网络分割策略
A Network Partition Scheme for Restoration in Optical Networks
-
摘要: 网络规模的增大和复杂程度的提高给现有的集中式故障恢复策略的实施带来了困难。本文提出了一种分布式子网分割策略，这种方法可以将大型光网络分割成若干个具有中心节点的环形子网，进而在每个子网中实施分布式管理和故障恢复。文中给出了具体的网络分割过程，并给出了相应的子网恢复策略。最后通过一个实际的网络对这种网络分割策略进行了测试。实验结果验证了此策略的可行性和实用性。

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. -
