An Optimization Model Algorithm Based on MPLS Network
MPLS has becomed the important technique in NGN'development,contributing for doing an efficient Traffic Engineering(TE) in order to provide the QoS and to optimize resource allocation.For this purpose,it is possible to apply Mixed Integer Mathematical Programming(optimization) techniques to model routing problem minimizing implantation,operation and maintenance network costs.we present an optimization model applied to the MPLS network planning,which assign paths based on capacity and network architecture constraints,considering LSP survivability.The model is consolidated in two case studies, applying them to plan a MPLS network.The main characteristics of the MPLS concerning to the network planning approach are presented.
