You're either implementing IntServ (hard) or DiffServ (soft) QoS.

The problem is IntServ isn't really practical or scalable unless you have a very small network; it also isn't very resource conservative.

If using DiffServ aware TE then you're going to have to setup queueing policies on all of your interfaces in the network.  RSVP will do the admission control, but you'll still need to have your service policies on all the interfaces the LSP's traverse.
