A multilayer solution for path provisioning in new-generation optical/MPLS networks

Abstract: This paper proposes an offline solution for global path provisioning in new-generation optical networks based on the generalized multiprotocol label switching (GMPLS) paradigm. This solution is based on a multilayer approach, which involves both the optical and the electrical layers and optimizes the network configuration and traffic routing. The proposed global provisioning solution can be easily combined with dynamic routing solutions, providing the network with the possibility of reacting promptly to traffi… Show more

“…RWA is an optimization process to be carried out in stochastic environments considering multiple goals and constraints. A number of approaches to solve RWA including several scenarios have been related and some of them can be found in [1,10,[16][17][18][19]. Among several efficient approaches, the genetic algorithm (GA) has been successfully used to solve multi-constrained and NP-complete problems [20], as RWA is [1,17].…”

“…In this work we detailed the policies and their modelling. Most of the recent works [5,2] have dealt with heuristics for offline routing, multilayer networks and multihop traffic grooming. They have not considered the use of policies to accommodate new on-line (dynamic) requests in the overlay model taking into account QoS and the overhead to remove and reroute packet-based LSPs.…”
