Performance modeling of the Transport Control Protocol (TCP) has received a lot of attention over the past few years. The most commonly quoted results are approximate formulas for TCP throughput and document download times which are used for dimensioning of IP networks. However, the existing modeling approaches unanimously assume that packet loss only occurs for data packets (i.e. for packets from the server to the client), whereas in reality the packets in the direction from the client to the server (e.g., ACKs) may also be dropped. The simulations with ns-2 show that this bi-directional packet loss may have a strong impact on TCP performance.
