Topik: Optimal Flow Control; Multirate Multicast Networks Fulltext: AC021407.PDF (163.17KB) Isi artikel In this paper, we consider the optimal flow control problem in multirate multicast networks where the receivers of a multicast group can receive service at different rates with different QoS. The objective is to achieve the fairness transmission rates that maximize the total receiver utility under the capacity constraint of links. We first propose a necessary and sufficient condition for the optimal solution of the problem, then derive a new optimal flow control strategy using Lagrangian multiplier method. Like the unicast case, The basic algorithm consists of a link algorithm to update the link price, and a receiver algorithm to adapt the transmission rate according to the link prices along its path. Specially, if some groups contain only one receiver and become unicast, the algorithm coincides with our previously proposed unicast algorithm.
