Research in Multicast Networking

The recent success of multicast applications such as Internet teleconferencing, distributed interactive simulation, and data dissemination applications illustrate the tremendous potential of applications built upon wide-area multicast communication services. Our ongoing research is focussed in two crucial areas of multicast networks: reliable multicast protocols and call admission in multicast networks.

Reliable Multicast Protocols

While some multicast applications (such as video and voice) do not require reliable data transfer, others (such as shared whiteboards and data dissemination) do. The requirement of reliable data transfer for this last set of applications poses a difficult challenge to network designers - how to design and implement a reliable multicast protocol that can handle 100s or 1000s of participants. We are currently pursuing several related efforts in the area of reliable multicast protocols: In addition to these research efforts, we also have ongoing work in the areas of multicast flow control, and the development and analysis of an approachs towards relaible multicast that use multiple multicast groups for error recovery purposes

Call Admission in Multicast Networks

(This part still under construction).
