Abstract

This paper studies to which extent variable delays in mobile networks affect TCP performance. Our main contribution is a simple analytical model that determines the TCP timeout duration from given network parameters. Based on the model, we quantify the risk of spurious timeouts and their impact on TCP goodput. Our results show that TCP is quite insensitive to variable delays.
