Abstract
The paper proposes a new QoS framework, called on-demand QoS path (ODP), which provides end-to-end QoS guarantees to individual flows with minimal overhead, while keeping the scalability characteristic of DiffServ. ODP exercises per-flow admission control and end-to-end bandwidth reservation at the edge of the network and only differentiates service types in the core of the network. In addition, to be adaptive to traffic load, ODP monitors the bandwidth utilization status of the network and performs dynamic bandwidth reconfiguration in the core based on the network status. Through extensive simulations, the performance of the proposed architecture is investigated and compared with that of IntServ and DiffServ architectures. The simulation results clearly show that ODP could provide end-to-end QoS guarantees to individual flows with. much less overhead than IntServ. © 2003 IEEE.
