It resembles the AG, where all the nodews "join" a specific multicast
group. There are Venue Servers that, as the AG venue server also does,
tells the client which multicast group is associated with the selected
Venue.<br>

<pre wrap="">AG Tech, Bob, and Cindy,
How does Conference XP initiate, maintain, and teardown the connection
between sites/nodes? Is it a SIP/H.323 ITU like IP dialing protocol or does
it resemble the AccessGrid/VRVS virtual venue HTTPS certificate server
model.
Thank you,
John

Subject: Re: [AG-TECH] Conference XP vs AG
Here are my observations (overlooking the Windows-only thing):
1. ConfXP is more "user-friendly" - you don't need a node operator, unix
expert, a magic wand, or need to wave a dead chicken & chant to make it
work.
2. The video is much better - ConfXP takes advantage of the Windows Media
API's and does a very nice job rendering the video & audio - lipsynch has
not been a problem for me in my test sessions with folks in Europe.
3. A "bridge" is provided for multicast-challenged users and to use it, the
user simply uses a pull-down menu item on their ConfXP.
4. the integration of the client with the TabletPC is compelling (at least
to me). It allows the instructor/presenter to face the "audience"
instead of pointing at a screen and allows interactive mark-ups on the
presentation.
5. you can specify point-to-point connections for two sites, and it seems to
work well for the bandwidth challenged locations.
Thats my $.02

<pre wrap="">Hi everyone,
I was just wondering if anyone has had a chance to test Microsoft
Conference XP? What are the major differences between AG and
Conference XP? (aside from the fact that Conference XP only runs on a
windows macine) I was looking at their documentation, and they use the
exact terminology that AG does, almost the same equipment list, and
seem to have the same results.....but I just wanted to hear from folks
who have actually used it....
We are going to do a collaborative education project with a remote
site who is leaning toward Conference XP and they want to know what
the differences are and what the compelling arguments are for either....
Thanks
Cindy
