多域光网络中应用混合拓扑聚合的分段保护算法
Segment-shared protection algorithm based on hybrid topology aggregation for multi-domain optical mesh networks
摘要
Abstract
In order to deal with the survivability problem in multi-domain optical mesh networks,this paper proposed a new hybrid topology aggregation scheme at first. This scheme combined the advantages of the full mesh model and spanning tree model to tradeoff between accuracy in preserving the original topological features and compactness in representation to achieve scaling. Then it proposed an improved segment-shared protection approach called HTASP. Simulation evaluation shows that the proposed scheme is effective in multi-domain path protection with lower blocking probabilities and less inter-domain link update messages.关键词
