MλT: a multicast protocol with QoS support

This paper describes the new multicast protocol MλT, supporting QoS requirements. MλT is dedicated to any QoS parameter λ that is either additive (e.g., delay), or convex (e.g., available bandwidth). MλT constructs a multicast tree connecting a group of users such that, for any user x, the QoS λ supported by the path from the root of the tree to x is optimized under some constraints of bounded control traffic. Simulations on the UUNET network topology, as well as simulations on network topologies obtained by INET-3.0, show that MλT performs in average significantly better than QoSMIC, RSP strategies (e.g., CBT and PIM-SM), and greedy strategies.
