Just to clarify Mike's comments. When using our bridge (unicast), you are reliant on multicast from our server (in Chicago) to the other multicast sites. If other sites are bridging using another bridge (an NCSA AG2 venue for instance), then the multicast would need to be stable between the two bridge locations. We are launching an inSORS server on an Internet2 site (through the Internet2 Commons Hosted Environment Project) which will improve multicast reliability from our bridge. More on this when we finalize testing of the new server.
If everyone uses the same bridge, then it is unicast to everyone. This puts heavy bandwidth and processing at the server site but is the most reliable. AG2 Toolkit sites cannot use an inSORS bridge unfortunately (for now at least). inSORS site can connect an AG2 bridge through Manual Bridge option if you know the ip and ports for the particular venue. -----Original Message----- From: owner-ag-t...@mcs.anl.gov [mailto:owner-ag-t...@mcs.anl.gov]On Behalf Of Michael A Gideon Sent: Tuesday, April 19, 2005 12:25 PM To: Joe Barron; ag-t...@mcs.anl.gov Subject: RE: [AG-TECH] Multicast Issues Hi Joe, I was having similar issues a month or so ago. inSORS told me their multicast was not stable, and to use unicast instead. I tried it and the problems went away. I don't know if it was their software or some network issues.

We connected just fine in a conference yesterday in the Walkabout venue. This morning, we can get and transmit audio but we are not getting and no one is receiving video. Another site in Texas has reported similar issues. Is anyone aware of any larger I2 issues currently? Regards Joe Barron Texas A&M University
