Social Welfare Maximization Oriented Admissions Control over Delay-Sensitive Media Streams
Jun Liu · 2012
The performance of most real-time streaming media applications is sensitive to transmission delays. This paper describes a distributed admissions control method to ensure the required sending rates for the real-time media streams. A utility function is first developed to model the satisfaction of delay-sensitive media streams. Then, the optimal admissions control on streams are formulated into a social optimum oriented network utility maximization (NUM) problem. A distributed admissions control method can be developed based on the dual decomposition of the primal problem. The construction of this distributed admissions control method follows the DiffServ approach.
