Progress Report on XMSF Modeling and Simulation Framework Activities (August 2003)

This report outlines the activities and significant accomplishments of the XMSF (Extensible Modeling and Simulation Framework) during March to August 2003. Key highlights include the investigation of Overlay Multicast for the framework, the creation of a pre-prototype, the initial deployment of a distributed testbed, and a demonstration of Selectively Reliable Multicast. Additionally, a course on Networking Virtual Environments was delivered over the Internet, showcasing advancements in community development and collaboration with multiple organizations such as SISO and OGC.

  6. XMSF Overlay Multicaster (XOM) • August ‘02 Monterey workshop identified many-to-many multicasting with Quality of Service as a significant technology gap for Web-enabled M&S • and overlay multicast as a solution • approach emerging at CMU, MIT, elsewhere • Funding not available for prototype in 2003 • did a study instead (published in DS-RT’03 paper) • but we have been able to create a pre-prototype as GMU/NPS student project • potential: multicast with QoS-priority Internet-wide! • also compatible with reliable multicast development XMSF Activities
