Abstract
A network is defined to be a congested networkif the load on the network exceeds the capacity of the network. The traditional congestion control technique of slow-start and AIMD was adopted when the aim was more on the stability of the Internet. But as more and more time critical applications such as multimedia applications are being used, we need alternate technique that reduces the drastic fluctuations of window size present in the existing technique. Thispaper proposes a techniquefor fast delivery of packet for a time critical application. It reduces the packet overhead and time compared to existing slow-start and AIMD technique. The proposed technique uses information or intelligence from the unexpected packet received. It is a fine modification of the existing slow-start and AIMD technique by adapting them for time critical applications. We propose modification at both thesender and the receiver hosts without modifying anything in the intermediate hosts of the network. Extensivesimulation show that proposed technique reduces congestion in the network by reducing both packet overhead and time compared to the traditional slow-start and AIMD technique and delivers the packets in timely manner than the existing techniques.
