MλT: a multicast protocol with QoS support
J. Ignacio Alvarez-Hamelin, Pierre Fraigniaud · 2004
This paper describes the new multicast protocol M/spl lambda/T, supporting QoS requirements. M/spl lambda/T is dedicated to any QoS parameter /spl lambda/ that is either additive (e.g., delay), or convex (e.g., available bandwidth). M/spl lambda/T constructs a multicast tree connecting a group of users such that, for any user x, the QoS /spl lambda/ 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 M/spl lambda/T performs in average significantly better than QoSMIC, RSP strategies (e.g., CBT and PIM-SM), and greedy strategies.
