Yang, If different entry points to a diffserv domain apply different admission control rules then traffic entering at those points will get different shares of the bandwidth at the entry point, but once the traffic gets mixed up in the core of the domain, all traffic sources will be getting the same treatment. In other words any CIR differentiation at the entry points will vanish in the core. (That's assuming an IP network of course... MPLS is a different story).
