AAA based security architecture for multicast content distribution

Abstract

In this paper, we present a new multicast content distribution framework supporting content access control and accounting. MCDA2 (multicast content distribution architecture with accounting support) is based on the standard protocols Diameter and MLD (multicast listener discovery). It allows the generation and storage of individual and group accounting information of heterogeneous multicast members. This architecture offers easy integration and good scalability which could allow further multicast deployment
