Abstract

Multicast admission control in differentiated services network is an important but shortly researched subject. We propose a parameter-based admission control method. The method rejects new multicast join requests that would otherwise decrease the quality experienced by the existing receivers. DiffServ network edge nodes filter join requests and generate new requests. The proposed method is developed as an extension to the DSMCast protocol but could also be adapted to other protocols. In this paper the parameter-based admission control is compared to earlier created, measurement-based admission control methods, as well to situation when no admission control is used.
