This paper is concerned with the approximate performance analysis of TCP Reno connections coexisting with flows that are not TCP-friendly (i.e. flows that use more bandwidth than would any conformant TCP implementation in the same circumstances). The network model is based on two earlier models. The first model enables one to calculate the TCP send rate which is the amount of data sent by the sender in unit time. This model has been presented in [6] and captures the behavior of both the fast retransmit and time-out mechanisms. The send rate for a given TCP connection can be calculated assuming that the round trip time, the time-out and the loss probability are known for this connection. These quantities can be determined using the second model – the queueing network model that represents an IP network and has been introduced in [13]. It enables one to include the Random Early Detection (RED) queue based active queue management (AQM) scheme that can be met in today’s routers.
