Designing Different Models of Robust IP/MPLS Over DWDM Networks

Both IP/MPLS and DWDM layers can provide various resilient schemes to protect traffic from disruptions due to network failures. At the same time, both technologies provide the ability to realize virtual private networks. The aim of this paper, is to identify an optimal solution which provides a compromise between resilience time and network cost for different network models according to the network layer on which the different resilience schemes are implemented and the network layer on which virtual private networks are realised. Extended mathematical models for individual network layers for optimization are proposed to compare the different network models with the ASON network architecture.
