Analysis of the impact of Duplicated ACK on the performances of TCP

The need for evolution, change and constant communication are the forces that drive the advancement of the modern telecommunications. All IP networks with centralized management are reality. TCP is the most important and most used protocol in the todays wired and wireless communication. If we want to improve the throughput of the network then we have to improve the transport protocol, to optimize it and predetermine its behaviour in variety of environments. In this paper we conduct detailed analysis of the impact of the Duplicated ACK parameter on different performance parameters such as throughput, congestion window, slow start threshold, in bottleneck scenario with incorporated loss models under network load with different versions of TCP traffic.
