GMPLS - simulation tools

Abstract

The GMPLS is known as one of the most important technologies for solving many problems over the Internet. Recently, significant work has been completed on the recovering and protection mechanisms of data and the control plane of GMPLS network. Still, new enhancements should be proposed to improve the efficiency of traffic engineering. Therefore the simulation tool supporting GMPLS network is desirable. The available network simulators are analyzed and as a result NS-2 and OPNET are proposed on research in this area. An example of separation data and control plane of MPLS in NS-2 simulator is presented. Further extensions of NS-2 are necessary to the complete support of GMPLS simulation.
