Performance evaluation of different versions of 2D Torus network

Interconnection networks have been emerged as an efficient communication infrastructure to fulfill the heavy communication requirements of several applications. Torus is the most efficient interconnection network for current and future supercomputer systems. The packet delay and throughput are the major performance metrics for evaluating the network topologies in designing a network. This paper, evaluates the performance of different versions of torus interconnection networks viz. classical Torus, XTorus, and CCTorus under two different traffic applications i.e. CBR and FTP, in two different scenarios i.e. at varying simulation time, and varying network size, using dynamic routing. Here the main emphasis is given on the average delay and average throughput performance metrics. NS2 tool is used for designing and simulating the performance of the network. By this analysis we can design a better structure that will give better performance in terms of bandwidth and delay.
