In this paper we propose a DiffServa rchitecture for the support of real time traffic (e.g., video) with QoS constraints (e.g., bandwidth and delay) over an IP domain. The main goal of the paper is to identify solutions which provide QoS guarantees without requiring per flow processing in the core routers (as is commonly done in IntServs olutions) and which are thus scalable. We propose, and evaluate through simulation, different approaches for call admission control (CAC) and resource allocation. These approaches are all consistent with the DiffServmo del, but place different processing and signaling loads on edge and core routers. Paths are computed by means of a QoS routing algorithm, Q-OSPF, and MPLS is used to handle explicit routing and class separation.
