Abstract
To obtain a trade-off between veracity and complexity when simulating TCP traffic, a hybrid simulating framework is proposed based on the packet-level simulation and aggregated control. The aggregated TCP traffic of access network in the gateway is proposed as simulated object, instead of the traffic generated at individual host or session level. The framework is divided into four parts: Traffic Generator, Transmission Controller, Traffic Sink and Network. The traffic with self-similarity or multi-fractal property at application level is generated by Traffic Generator. The Transmission Controller sends packets to Traffic Sink based on aggregated control. The Transmission Controller also sends control information to Traffic Generator according to the status of Network, and the Traffic Generator decides how to change the generating mode of traffic. The simulation results of non-congestion case and congestion case show the validity of the framework. The time cost shows our simulating framework possesses better performance.
