Transport Protocols and Performance Analysis

Research Description

Analysis of networks is crucial to gaining insight and understanding of how large systems behave. Our research has focused on the accurate characterization of TCP, congestion control mechanisms, quality of service with TCP/IP, to wide-area traffic characteristics.
