This paper describes two new approaches that are capable of ensuring delivery guarantees to multicast sessions on IP-based networks, according to the diff-serv model. We present the CDSAMA and DVMA2 quality-of-service (QoS)-sensitive multicast routing algorithms that may be used to implement a centralized bandwidth broker and support multiple QoS constraints, namely, bandwidth, delay and fair delay. We describe an end-to-end call admission multicast protocol that operates as a distributed bandwidth broker and adopts an approach which is simple, scalable, operates on a per-call basis and supports the group membership dynamics. We discuss some performance evaluations obtained by implementing the proposed solutions in a simulation environment.
