I'm curious to see how many of you are utilizing diffserv vs. RSVP in your QoS implementations. Personally, I've found diffserv to be more flexible and generally easier to implement but I wouldn't necessarily count myself as an expert on RSVP. Are there any RSVP users out there?

Not sure how many of you are doing it, but you can use the Orion NetFlow application to monitor traffic levels via QoS. This feature is new as of the last couple of months, but has been helpful in some of the testing I'm doing.

Also, since I've been doing some research on QoS lately I thought I'd share a couple of interesting sites I found:
