Abstract :
We study optimal flow control in multiservice networks, in which users (controllers) optimize their performance objectives in a decentralized manner. We adopt a model that differs from previously considered ones in that a user´s strategy (viz., flow or average rate) is constrained between two numbers: those are specified by the user´s quality of service (QoS) requirements or by the user´s technology. Adopting the generalized power as the performance measure, we prove existence and uniqueness of the Nash equilibrium point (NEP) and suggest a simple algorithm to determine this NEP.
