An overview of performance comparison of different TCP variants in IP and MPLS networks

Abstract

Researchers have shown considerable interest in TCP variants and their behavior under different traffic conditions by conducting research on congestion management of TCP in IP supporting networks. TCP provides a trustworthy end-to-end data transfer under changeable wired networks. To overcome the problem of unreliability of IP network, TCP is used. Many service providers are now moving to MPLS over Inter- net to transfer data, preferring it over traditional transferring strategies. Different variants of TCP show varying behavior in best effort Internet Protocol networks. This paper presents an extensive investigational study of TCP variants under IP and MPLS networks by focusing Tahoe, Reno, New Reno, Sack and Vegas under File Transfer Protocol (FTP). © 2011 Springer-Verlag.
