Survivable Design of Reconfigurable MPLS VPN Networks
MPLS has become an increasingly common technology for guaranteed transport services for carrying customer traffic. The authors consider the survivable design problem from the perspective of an MPLS VPN network provider where the data rate required is dynamically configurable based on customers' traffic demands. Network optimization formulations for global design and end-to-end fast reroute design are presented. For the global design model, the authors present two variations: global sequential redesign and selective sequential redesign.
