6. DMSO Review 25 June 2003 XMSF Activities 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
