A Scalable and Efficient Inter-domain QoS Routing Architecture for Diffserv Networks
: With Bandwidth Broker (BB) support in each domain, Differentiated Services (Diffserv) is seen as a key technology for achieving QoS guarantees in a scalable, efficient, and deployable manner in the Internet. In this paper we present a Route Server (RS) architecture that is compatible with the BB model for inter-domain QoS routing. The RS is responsible for determining QoS routes on behalf of all the routers and for exchanging routing information with its neighboring peers. It optimizes network resources by taking the intra-domain resource utilization state into account for selecting a route. It also achieves scalability by pre-computing a limited number of paths for each destination region and mapping all the packets to one of these paths regardless of their sources. Key words: Bandwidth Broker (BB), Inter-domain QoS Routing, Route Server.
