Implementation of software router embedded PID AQM algorithm in the communication test network

At present, most studies on the communication are based on simulation, but any theory needs to stand the test of the physical environment. This paper implements the embedding of PID AQM algorithm in software router-IPCop in the communication test network. And the comparison of results from NS2 simulation and the communication test network proved that the embedding method was correct. The method of embedding the new algorithm in software router has been proposed in this paper, which means the AQM algorithm is applied to the real network environment.
