Abstract:
The Telecollaboration (TC) business system, an
important class of emerging applications that is spawning new
challenges to achieving the desired levels of performance. One
important implication in identifying and characterizing the
properties of TC system implementations is that performance
evaluation should no longer be isolated and viewed as a separate
analytic activity. Instead, we require a physical and logical
understanding of the complex quality issues that affect overall
performance of applications, systems and network
infrastructures. As one of the natural artifacts of this practice, a
workload model will be developed to characterize a TC system.
We demonstrate how such an analysis may result in
characterization of workload behavior, and that in turn will lead
to definition of efficient analytical model parameters, network
invariants and use of relevant quality metrics. The study of
underlying issues of Telecollaboration Quality of Service (TQoS)
within the context of TC could have positive impacts on
performance analysis and traffic control, if the analytical
modeling used remains consistent and effective in describing the
Web-based environments.
