Goal: Improve bandwidth delivered to a set of multicast receivers
Motivation
Bullet
Research Directions
· State of the art
· Construct an overlay tree
· Probe for acceptable bandwidth to parent
· E.g., Overcast, Narada
· Challenges
· Bandwidth monotonically decreasing down the tree
· Should be TCP-friendly
· Bandwidth probing incurs high network overhead
· Probing interferes with data dissemination

° Compare to "overlay network bottleneck tree"
° Adapt the protocol for multimedia streaming
