In next generation Internet, there will be more and more applications that require real-time transmission and multicast services. To fulfill these requirements, Integrated Services (IntServ) and Differentiated Services (DiffServ) are thus proposed. The IntServ architecture provides an end-to-end QoS guarantee on a per-flow basis. The DiffServ architecture, on the other hand, provides QoS guarantee to aggregate of flows, and is more scalable for backbone networks. In this paper, we propose an integrated environment in which local access networks provide DiffServ. Issues on how to map service classes between these two types of network and how to provide multicast services are discussed and possible solutions are proposed.
