Dean, Just limiting my reply to one point: >That relegates RSVP to the enterprise Lan, where it usually isn't needed. >Remember, RSVP is only useful if you have a congestion problem and need to >choose which packets to discard. If you have no congestion problem, then >you have no need of RSVP. However, having a congestion problem also opens >the question of the nature of the congestion and what is the best way to >deal that problem. I was involved in a study done by Genuity and Cisco in >which the congestion problem was found to most often involve the tail >circuit--the link between the customer and the ISP. The best solution for >this problem was found to be low latency queuing, not RSVP. Adding VOIP to an enterprise LAN can often add to congestion. Some on-path signaling can help here - not to mention NAT & FW traversal issues. RSVP doesn't solve these, but NSIS is looking into these issues.
