In this paper, we model and analyze an admission control scheme to be used by inelastic flows in coexistence with elastic flows running fair congestion control (TCP). The admission control can be implemented with different level of aggressiveness (relative to the elastic traffic). A totally aggressive version of the admission control would admit an inelastic flow even if this means elastic flows' fair bandwidth share is reduced to close to zero. In the other extreme, a TCP-friendly version of

We show that the performance of inelastic flows is insensitive to their aggressiveness; whereas the performance of elastic flows is at the mercy of the aggressiveness of the inelastic flows. This makes a strong case for adopting TCPfriendly admission control in a heterogeneous network.
