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 under the IETF integrated services (IntServ) paradigm. Our architecture offers the attractive feature of in-sequence delivery for all packets, albeit some of which may be out-of-profile. Simulation results show that, once admitted into the network, our architecture and traffic management algorithms provide hard performance guarantees to GS flows under all conditions, consistent (or soft) performance to CL flows under both light load and heavy load conditions, and minimal negative impact to in-profile GS, CL and BE traffic should there be any out-of-profile behavior from some flows.
