A model for real-time simulation of large-scale networks based on network processor

Real-time network simulation refers to simulating computer networks in real time so that the virtual network can interact with real implementations of network protocols, network services, and distributed applications. This paper proposes a new model for real-time simulation of large-scale networks based on powerful network processor. The scheme takes advantage of discrete event system simulation model to simulating large-scale network. This paper describes the implementation of network simulation technology based on Intel IXP2400 platform. Experiment results show that the model can simulate large-scale network, learn routing entries automatically and forward packets at wire-speed.
