Comparative Analysis of Transport Layer Congestion Control Algorithms

Internet applications are increasing network traffic exponentially these days due to remarkable growth of the Internet. To handle the huge traffic on Transport Layer one provides the most trusted, Connection oriented and end-to-end packet delivery protocol which is Transmission Control Protocol (TCP). There are many problems available in congestion control algorithms i.e. transfer size of the packet, initialization of Congestion Window, cross traffic, congestion along the path, size of the router buffer, intra protocol and inter protocol fairness. There are many variants of the protocol available to control the congestion. This paper presents a comparative analysis of commonly used TCP flavors. We present analysis of TCP protocol named, TCP Reno, CUBIC-TCP, FAST-FIT, TCP New Reno and followed by experiment results.
