Abstract/Summary: | |
Scope and method of study. VOIP traffic is being exchanged by carriers for termination. This traffic has unique characteristics that depart from traditional exponential models. This VOIP gateway traffic is modeled and applied to an optical burst switch assembly algorithm to characterize the output traffic. As part of the research a discrete event simulator is used and custom modules are built to simulate assembled optical burst switched traffic.;Findings and conclusions. An important finding is that VOIP traffic from network gateway switches does not follow the traditional models assumed. The traffic distribution indicates that buffering of calls occurs in the gateway which changes the expected random distribution of calls. Call interarrival times from the packet network were found to best match a Weibull distribution, instead of an exponential distribution. The Optical Burst Switch assembly process was shown to not change the self-similarity characteristics of VOIP traffic. |
