Hello all The room name is "Sapphire" in Hilton Anatole. It is located 1st floor of the Tower. We will put a poster on the message board.
For tele-conf. We prepare our bridge and polycom for remote a participants. Mail <ug at xcast.jp_NOSPAM> & <yoneda.takahiro at jp.panasonic.com_NOSPAM> for bridge information. -- ug Aaron Falk wrote: > === Call for participants === > > Unofficial Meeting of Scalable Small Group Multicast(SSGM) for IRTF > http://www.net.itc.nagoya-u.ac.jp/SSGM/ > >Date : March 19, 2006 (20:00--23:00) >Place: Room <TBD> , Hilton Anatole (Same hotel of IETF 65th), Dallas >TX, USA > http://www.ietf.org/meetings/IETF-65.html > Room will be announced on the MLs and the message board. > >IP Multicast has proved useful in transmitting information such as >voice and video to large groups.
