Simulation of Traffic Engineering in IP-Based Networks

Abstract

A practical function of traffic engineering in IP-based networks is the mapping of traffic onto the network infrastructure to achieve specific performance objectives in respect of traffic-oriented and/or resource-oriented. The simulation of such traffic engineering function is necessary needed while planning and optimizing the network resources. This paper describes an new model for analytical simulation of the traffic mapping in IP-based networks in respect of both real-time and best-effort traffic. We mainly conceptualize the simulation as an behavioral modeling of network dynamics. We then mathematical formulate this behavioral modeling as two sub-optimization tasks corresponding to both real-time and the best-effort traffic delivering. As an example of our algorithm implementations, an genetic algorithm for real-time traffic mapping is presented. The article also gives some numerical results from practical examples.
