TCP Variants and Network Parameters: A Comprehensive Performance Analysis
Waselul Haque Sadid, M. A Rahman, S. Anam · 2009
Abstract— Transmission Control Protocol (TCP) includes eleven variants-Tahoe, FullTcp, TCP/Asym, Reno, Reno/Asym, Newreno, Newreno/Asym, Sack1, Fack, Vegas and VegasRBP as source and five-TCPSink, TCPSink/Asym, Sack1, DelAck and Sack1/DelAck as destination, implemented in Network Simulator (NS-2). Performance of TCP versions indicates how they respond to various network parameters-propagation delay, bandwidth, TTL (time to live), RTT (round trip time), rate of packet sending and so on. Such analysis is immensely in need to be aware of which TCP is better for a specific criterion, wherefrom an appropriate one will be selected in respective network to optimize traffic goal. But yet no complete summary is available as we've investigated hereby thoroughly. Recently published researches considered Congestion Window, Throughput, and Delay for five variants only. This paper covers all the supported variants to observe their nature regarding to five new perspectives in details. Index Terms— TCP, BSS, RTT, TTL NS-2.
