Abstract


Survivability is a key technology of intelligent optical networks , multi-domain , multi - layer optical network coordination mechanism between the layer , multi- domain topology and routing information not visible constraints , making more complex multi-domain multilayer optical network survivability . Papers critical technology for multi-domain the multilayer optical network survivability , theoretical analysis and simulation methods . The paper first outlines the the light network survivability principles and technology , focused on multi-domain key technology of multi - layer optical network survivability . For the multilayer survivability issues , analysis and discussion of the multilayer independent and integrated recovery strategy . Survivability issues for multi-domain , multi-domain optical network logic polymerization and precomputed dynamic protection mechanism and M : 1 static protection mechanism for intra-and inter-domain . The paper presents the minimum cost of a domain Traffic Engineering (MC TE) routing algorithm , the algorithm can select the shortest on the basis of both the network load , thereby enhancing the network load balancing . The paper also proposes a dynamic protection mechanisms to improve resource utilization , through numerical simulation method to verify the performance of the algorithm .
