Demo abstract: An integrated tool of applying stochastic network calculus for network performance analysis

Abstract

With the recent emergence of online network performance measuring tools, Internet users are now able to measure their received service levels. Such user-initiated network performance measurements push the ISPs to an ever-high standard, requiring them to know the worst-case performance of its admitted flows, whether and where to accommodate a new flow request, without violating the service agreement level (SLA). Stochastic Network Calculus (SNC) has been developed to derive performance bounds of a network system for many years in the research community. However, it has not been practically adopted by ISPs due to the lack of a tool supporting features such as end-to-end analysis or optimal parameter tuning. In this demo, we extended the DISCO Stochastic Network Calculator. We also compare the analytical results obtained from the tool with the simulation results obtained in NS-3 to validate the tightness of the performance bounds.
