Many real-time applications use Internet as a media to transmit their data and need guarantee for correct data transmission and limited transmission delay. It requires efficient network traffic protocols to avoid or limit the level of congestion. In this paper we propose, design and analyze a Robust Delay Based Controller (RDBC) for traffic management on transmission control protocol (TCP). This controller is based on an output feedback controller for decreasing effect of delay and disturbance on performance of network. Linear Matrix Inequality (LMI) is used for optimize design objectives. The simulation results illustrate that the queue length in router reaches to desired value quickly with proposed RDBC. We use network simulator (NS2) to compare performance of RDBC with other AQM mechanisms Like RED, PI and PID. Queue length average and variance, bandwidth utilization, throughput and end-to-end delay are performance metrics that used for comparison.
