Today Transmission Control Protocol (TCP) is most widely used transport layer protocol because of its reliability. One of the major problems of TCP is the unequal sharing of bandwidth for a set of TCP sessions sharing the same bottleneck. This unequal use of bandwidth is can be a result of varying Round Trip Time (RTT) or different segment sizes of different TCP sessions. Since TCP is the de-facto standard protocol for reliable data transfer, it seems the users must accept these limitations. Fortunately, that is not the case, and the situation can be improved. This paper analyses the problem TCP faces when multiple TCP session are established each having a different RTT.
