Abstract

The main problem complicating multicast video transport is variation in network bandwidth constraints. This paper presents a novel credit-based multicast flow control approach, which allows for potentially full utilization of all branches in a multicast tree at the expense of low priority packets losses. It uses hop-by-hop flow control as well as explicit rate congestion feedback from the destinations. The responsiveness, bandwidth utilization, video quality and fairness of the mechanism are evaluated through simulations. Results suggest that the proposed mechanism is capable of providing a high quality video service in the presence of varying bandwidth constraints.
