Paper Abstract

Constraint-based routing algorithms are a key component to meet various requirements subjects to a set of constraints for bandwidth requests in the GMPLS-based optical networks. The purpose of GMPLS control plane is to provide an intelligent automatic end-to-end label switched path provisioning/signaling framework to support arbitrary bandwidth traffic. We developed a detailed simulation platform for an IP-over-MPLS-over-WDM network, so that extensive simulations are carried out to evaluate the network performance of various routing algorithms and routing strategies with RSVP-TE or CR-LDP signaling protocol in GMPLS-based IP/MPLS optical networks in terms of blocking probability. The simulation results show that the signaling protocol improves the network performance more significantly than multi-fiber configuration and CR-LDP signaling mechanism outperforms RSVP-TE in all cases. Furthermore, the LCF routing strategy also has better performance than LCL strategy.
