Performance Analysis of TCP Variants


Abhishek Sawarkar, Himanshu Saraswat


Vol. 16  No. 4  pp. 102-106


The widely used TCP protocol was developed to provide reliable end-to-end delivery of packets under varying degrees of congestion in the network. This paper presents with in-depth study of performance characteristics of different TCP variants viz. Tahoe, Reno, New Reno and Vegas under congestion. We carry out simulations in NS-2 environment on these TCP variants and analyze the results with respect to throughput, packet drop rate and latency to determine if there is an overall efficient TCP variant. We also study the performance of Reno and SACK for different queuing algorithms viz. Droptail and RED.
