A Note on the Fairness of Tcp Vegas
نویسندگان
چکیده
This paper shows that TCP Vegas’ fairness critically requires an accurate estimation of propagation delay. We also show that, in practice, this may be difficult to achieve and we discuss how to choose the parameters and that control the window sizes’ update.

Analysis and Improvement of Fairness between TCP Reno and Vegas for Deployment of TCP Vegas to the Internet
According to the past researches, a TCP Vegas version is able to achieve higher throughput than TCP Tahoe and Reno versions, which are widely used in the current Internet. However, we need to consider a migration path for TCP Vegas to be deployed in the Internet. By focusing on the situation where TCP Reno and Vegas connections share the bottleneck link, we investigate the fairness between two ...

Tbmugbput fairness is an important d e r i a for evaluating TCP pe fomance. Fairness is especial! important for best effort service, which is still the dominant gpe o f service in the Internet and, predictab!, in the years to come. However, the TCP pmtocols prevailing in the Internet, including TCP Tahoe and TCP Reno, are known to be unfair, especial! to connections with larger mund-tnp delays....

TCP Vegas version is expected to achieve higher throughput than TCP Tahoe and Reno versions, which are currently used in the Internet. However, we need to consider a migration path of TCP Vegas when it is deployed in the Internet. In this paper, we focus on the situation where multiple TCP Reno and Vegas connections coexist at the bottleneck router, by which the fairness property is investigate...
متن کاملTCP Reno and Vegas co-existence
Several studies have been made comparing performance and fairness of different congestion control algorithms including TCP Reno and TCP Vegas. Those studies primarily focused on showing the advantages of TCP Vegas over TCP Reno in terms of performance, efficiency and fairness, and they show that Reno dominates Vegas in shared network environments. This work presents detailed analysis of the per...
متن کاملA note on the Fairness of TCP
We study the fairness of TCP Vegas. The latter is an alternative to the commonly used TCP Reno, and uses measures of the round trip time as feedback on congestion. We consider two cases that depend on the value of the two parameters and controlling the window sizes' update. Our main conclusion is that TCP Vegas is unfair in several points. First, when = , if the propagation delays are correctly...
