Although TCP behavior is one of the most studied aspects of Internet traffic, little is known about TCP performance within modern enterprise networks. In this paper, the authors analyze aspects of TCP performance observed in packet traces taken over four months from a medium-sized enterprise. They assess the prevalence of broken TCP transactions, applications used, throughput of TCP connections, and phenomena that influence performance, such as retransmissions, out-of-order delivery, and packet corruption. While much remains to explore, this paper represents a first step towards understanding TCP performance in the under-studied environment.
