In this paper, an intra-domain, multi-area Quality of Service (QoS) provisioning mechanism, namely the QoS-HBB architecture is proposed to alleviate the scalability problem in the intra-domain bandwidth broker design. By exploiting the inherent hierarchical nature of OSPF and the fact that an OSPF domain can be subdivided into multiple areas, QoS-HBB introduces two levels (i.e. intra-area and inter-area) of QoS provisioning within a domain. The proposed architecture allows the deployment of multiple bandwidth brokers in the backbone area and non-backbone areas.
