Abstract:Although the Differentiated Services architecture supports scalable packet forwarding based on aggregate flows, the detailed procedure of Quality of Service (QoS) flow setup within this architecture has not been well established. In this paper we explore the possibility of a scalable QoS flow setup using a sink-tree paradigm. The paradigm constructs a sink tree at each egress edge router using network topology and bandwidth information provided by a QoS extended version of Open Shortest Path First (OSPF). Simu… Show more
