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 Qo. S-priority Internet-wide! § also compatible with reliable multicast development XMSF Activities DMSO Review 25 June 2003 6
