QoS - Diffserv vs. RSVP

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:

Thanks,

We use diffserv across our network.  RSVP, to my knowledge, is not often used for QoS anymore, but rather been hijacked by MPLS for LSP establishment.

I've read several papers regarding type of service and DiffServ Code Point, and I'm still trying to figure out how to explain this to managment without getting wrapped around the axle. Is there a third vernacular for this? Management is looking at this as if it is a service of type ftp, http, udp, tcp, etc. What exactly is Netflow Traffic Analyzer trying to tell me here? And if I edit the Type of Service name, what would I be using as a guideline to unput this edit? Any input regarding this would be most appreciated, Thank you.
