Summary:We consider the problem of multimedia synchronization in a Web
environment. The workload generated by the multimedia server during a
Web session exhibits variations that are quite different from the
traffic fluctuation offered by a single media stream, e.g., a variable
bit rate (VBR) video. We propose a set of parameters that can be used to
characterize the workload generated by the multimedia server in a
Web-type browsing environment. The workload characterization scheme is
subsequently used in designing a server-based synchronization scheme.
The problem of scheduling multimedia information to ensure media
synchronization in a Web environment is identified as a multicriteria
scheduling problem, which is NP-hard. The ability of fuzzy control to
deal with multivariables makes it a good alternative for the
multicriteria scheduling problem considered. Consequently, we propose a
neuro-fuzzy scheduler (NFS) that makes an intelligent compromise among
multicriteria by properly combining some scheduling heuristics.
Performance of the NFS is compared with several known heuristics and a
branch and bound algorithm. The results show that the proposed NFS ran
dynamically adjust to the varying workload quite well
