Impact of services on network capacity: tool for seamless integration of service and network modeling

Abstract

This demo will present both real and mocked-up usecases of a software application that enables accurate probabilistic modeling of new IP based services and their impact on network resources. The demonstration should be of general interest to Network Service Providers (NSP), device manufacturers, and application developers. Network planning and service analysis is a very important issue for today's NSP's; new communications devices and services emerge quickly (e.g., VoIP, Peer-to-peer filesharing, etc.) and end-users demand network resources that are up to the task. For the analyst, our tool leverages familiar UML style views, used to capture prototypical service "sessions". It then allows annotation of the service model with a rich grammar, model conversion into semi-Markov form, and algorithm execution for network resource usage estimation.Ultimately, analysts gain insight into the impact of new consumer devices and services on their networks.
