Receiver-based path capacity estimation for TCP

Abstract

This paper presents a new TCP-based packet pair measurement approach for network path capacity estimation. It addresses some drawbacks other approaches still bear. In contrast to these, our approach uses an unmodified TCP sender and utilizes techniques to identify probing packets that were less influenced by cross traffic. These techniques are applied at the receiver side only. The concept is verified by simulation and an outline of the applicability for real-life measurements in the Internet is presented.
