[c-nsp] Web Conferencing

[Cheung, Rick]

	Anyone wrestling with the challenges of managing the bandwidth
consumption of web conferencing/video conferencing in their enterprise? I
realize there is no one-size-fits-all, and the obvious way to go is to
implement QOS, but wanted to confirm there wasn't an intermediate step to
take, aka: appliance.

	The goal is to protect the streaming traffic, and also protecting
against it so other apps wouldn't see a performance hit. The challenge is
where most web conferencing apps do not support multicasting, so the problem
arises when the apps also dont support admission control, where we can limit
one office to 1 session at any given time. The usage patterns show that
instead of congregating in a conference room to conserve on bandwidth, users
prefer to view the sessions from their PCs. 

	We've seen presentations from vendors such as Corvil and Vieo;
anyone have any first hand experience with the products? Corvil's technology
is apparently going to be added to the 12.3T train next year, to be had as a
feature license...
