A Dynamic clustering scheme based on coordination of management and control is proposed to reduce network congestion
rate and improve the blocking performance of hierarchical routing in Multi-layer and Multi-region intelligent optical
network. Its implement relies on mobile agent (MA) technology, which has the advantages of efficiency, flexibility,
functional and scalability. The paper's major contribution is to adjust dynamically domain when the performance of
working network isn't in ideal status. And the incorporation of centralized NMS and distributed MA control technology
migrate computing process to control plane node which releases the burden of NMS and improves process efficiently.
Experiments are conducted on Multi-layer and multi-region Simulation Platform for Optical Network (MSPON) to assess
the performance of the scheme.
We study the impact of light path routing on network survivability and present a Single-Node Failure Algorithm based
on current IP over WDM static topology mapping methods. The goal of the algorithm is to map the IP topology links
into light paths in WDM topology to ensure IP topology remains connected after the failure of a single node in WDM
