Re: Admission Control In DiffServ

Hi Liat,
In diffserv Bandwidth Brokers(BB) are responsible for admission control
and related issues. Every diffserv domain will have a BB and these BBs
talk to each other in order to support the inter-domain traffic. BBs are
responsible for admission control, resource allocation and provisioning
etc. BBs are centralized agents and requests are forwarded to BBs to let
it decide whether resources are available to support the request.
Hope this helps.
