Deployment Considerations for the TCP Vegas Congestion Control Algorithm
Sonia Fahmy, Mridul Sharma · Purdue e-Pubs (Purdue University System) · 2003
TCP congestion control has been the subject of significant research for more than two decades.Various algorithms including TCP Tahoe, TCP Reno.TCP NewReno.SACK.FACK.and their variations have been proposed to overcome the problem of network congestion and increase network utilizmion.The TCP Vegas algorithm has been extensively debated in recent years.TCP Vegas' behavior in the presence of competing TCP Reno connections has been the main barrier to its deployment.This paper studies TCP Vegas and investigates why it is less aggressive than TCP Reno in mixed configurations.Simularion experiments have been carried out to demonstrate the problems with the deployment ofTCP Vegas in the operational Internet.
