On Improving Data Dissemination Throughput in Application-Layer
 Overlay Networks

 Baochun Li


 In this talk, we investigate various approaches to increase the
 throughput of a particular data dissemination session by the
 construction of higher-quality topologies used for such dissemination.
 We propose distributed algorithms that seek to significantly improve
 end-to-end session throughput in typical dissemination sessions.  

 This objective may be achieved by taking advantage of the capability of
 overlay nodes to perform simple linear coding.  To this end, we seek to
 construct multiple data paths towards the receivers of the dissemination
 session, and utilize network coding to resolve interfering data paths in
 the generated topologies.  This is feasible since the overlay topologies
 are entirely malleable for the sake of improved performance.  We present
 simulation-based experimental results to demonstrate the validity of our
 proposed algorithms.
