Enabling Scientific Collaboration using Application-Level Multicast

Scientific collaboration applications such as large-scale reliable transfer of data to multiple sites, web-service notification, and video conferencing (e.g. Access Grid) require the ability to efficiently disseminate high-bandwidth content to a large number of geographically dispersed receivers. The limited deployment of IP Multicast has led researchers to investigate an alternate architecture called application-level multicast to support these applications. The goal of this project is to leverage recent advances in application-level multicast, and develop middleware for high-bandwidth multi-point content distribution which can serve as a fundamental building block for a wide range of scientific applications. We analyze current application-level multicast approaches, and argue that none of the existing approaches simultaneously meet all requirements of scientific collaboration applications. We will investigate issues in construction of data dissemination topologies for reliable data delivery, and integrating these techniques with GridFTP, and the Globus toolkit.
