Actually:

3) The best way to manage this situation is to use the Class of Service per-VC queuing feature. This will create a separate queue for each PVC, and will insure that offending PVCs don't affect other PVCs on the same interface. What it will also do is link

Layer 2 traffic engineering (ATM traffic shaping) to

Layer 3 flow control by using WRED to throttle TCP flows on PVCs which are exceeding their ATM PVC limits. As the TCP windows close, the packet flows will be reduced until they fit within the shaped PVC's limits.

Only one VC queue on the OC12 ATM interfaces on the GSR series. So, is it queuing delay or cell loss slowing it down? end __________________________________________________ Do You Yahoo!? Send online invitations with Yahoo! Invites. http://invites.yahoo.com
