Abstract
This article presents the comparison of different transport level congestion control schemes, including variants of the TCP (Postel, 1981). The protocol mechanisms, implemented in various protocols are hard to investigate in a uniform manner (Hosszú, 2005); therefore, the simulator SimCast (Simulator for multicast) is developed for traffic analysis of the unicast (one-to-one communication) and multicast (one-to-many communication) streams. In this article, the TCP and other transport protocol mechanisms will be compared using the SimCast simulator (Orosz & Tegze, 2001). The simulated results are presented through examples.
