Bullet: High Bandwidth Data Dissemination Using an Overlay Mesh
 

Summary: Bullet: High Bandwidth Data Dissemination
Using an Overlay Mesh
Dejan Kosti, Adolfo Rodriguez, Jeannie Albrecht, and Amin Vahdat
Duke University, http://issg.cs.duke.edu
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
Disseminate Disjoint DataDisseminate Disjoint Data
Compare to "overlay network bottleneck tree"
Adapt the protocol for multimedia streaming
