Session Abstract

A fundamental problem in providing end-to-end performance guarantees to applications in distributed environments, such as the Internet and Computational Grids, is to characterize the application traffic in terms of both network-level and application-level parameters. An application may be composed of multiple streams, and can be anycast. Further, the underlying service platforms are increasingly built on a combination of fixed line, satellite and wireless networks. Such heterogeneity introduces additional complexity of network parameters such as available bandwidth, delay, jitter and packet loss. In this talk, we present a general framework for statistical characterization of networked applications across multiple protocol layers that can identify the most important parameters affecting the end-to-end performance of the application and the underlying network, as well as provide mapping functions of their interactions. Access to such models will enable applications to respond to changing network conditions, especially in mobile and wireless environments where such adaptive behavior is crucial to maintaining user-perceived QoS levels. Such characterization methods can also help network providers design, tune, and provision their networks to accommodate different classes of applications more efficiently. We demonstrate the viability of the statistical characterization approach on an experiment testbed and show the validity of the overall approach.
