In this paper, a new algorithm is introduced that relies on a role-based access control model to reduce the amount of redundant information sent in multicast sessions. The algorithm utilizes the active nodes located in the multicast tree to reduce the amount of bandwidth wasted when the different roles assumed by the receivers in the multicast session have(More)
A new noncumulative layered multicast congestion control algorithm is proposed that can identify the location of congested branch(es) in the multicast tree and intelligently assign a dropping preference for each candidate layer. These preferences are assigned in a way that minimizes the number of affected receivers by dropping the corresponding layer. The(More)
