Modeling Mpls Routers By Petri's Networks

Abstract

Translate Article

MPLS addresses large networks; it is difficult to achieve a realistic model in the short term. This is why we plan to simulate different approaches. Our study is thus concretized by the development of models able to bring solutions to the problems of evaluation of the performances and improvement of the quality of the services of the networks MPLS. This paper presents the modeling of MPLS routers by colored Petri nets. Petri networks represent a mathematical tool, health in the field of modeling and verification systems; in addition to their analytical strength it provides a simple graphical representation which helps the modeling of complex systems.
