Research Activities
The research of the project has focussed on the systems issues of
deploying audio and video services over networks of switches with
differing characteristics.
Measurements of real traffic associated with the video services deployed
within Monash University, has shown different traffic patterns for
interactive usage of video in an educational context compared to the
traffic patterns of video traditionally measured for pay TV entertainment
applications. This has implications for the allocation of buffers in the
network switches, video servers, and end-user personal computers.
Research on the performance of ATM networks that provide an Available Bit
Rate (ABR) bearer service have highlighted the need to consider the
transient performance of the network resulting from sudden changes in
network traffic load that may result form the transfer of video traffic.
Research has also been conducted on new public network architectures that
result from a consideration of the changing costs structures of
transmission and switching equipment. The above research has been well
accepted internationally with presentations of the work at the
prestigious IEEE International Conference on Communications. Other work
includes studies of more efficient techniques for re-routing virtual
circuits in an ATM network in the presence of link failure, and the
performance of various techniques for transferring audio over
heterogeneous networks.
