Signaling Protocol for Session-Aware Popularity-based Resource Allocation

Authors

Abstract

The Differentiated Services model maps traffic into services with different quality levels. However, flows are treated unfairly inside each service, since the Differentiated Services model lacks a policy to distribute bandwidth between flows that form the same service aggregate traffic. Therefore, we present a signaling protocol that fairly distributes the bandwidth assigned to each service, among scalable multimedia sessions in a multicast environment. Fairness is achieved allocating bandwidth based upon the audience size of each session. We evaluate the efficiency of the proposed protocol using theoretical analysis and simulation.
