A Per-Flow Based Node Architecture for Integrated Services Packet Networks
As the Internet transforms from the traditional best-effort service network into QoS-capable multi-service network, it is essential to have new architectural design and appropriate traffic control algorithms in place. This paper presents a network node architecture and several traffic management mechanisms that are capable of achieving QoS provisioning for the guaranteed service (GS), the controlled-load (CL) service, and the best-effort (BE) service for future integrated services networks. A key feature of our architecture is that it resolves the out-of-sequence problem associated with the traditional design. We also propose two novel packet discarding mechanisms called selective pushout (SP) and selective pushout plus (SP+). Simulation results show that, once admitted into the network, our architecture and traffic management algorithms provide, under all conditions, hard performance guarantees to GS flows and consistent (or soft) performance guarantees to CL flows, respectively;...
