TCP is the dominant transport protocol used in the Internet and its performance fundamentally governs the performance of Internet applications. It is well-known that packet losses can adversely affect the connection duration of TCP connections-however, what is not fully understood is how well does the TCP design deal with losses. This paper systematically evaluates the impact of design parameters associated with TCP's loss detection/recovery mechanisms on the performance of real-world TCP connections.
