In this paper, we proposed a new QoS framework with Distributed Adaptive Resource Management(DARM). DARM provides end-to-end QoS guarantees to individual flows with minimal overhead, while keeping the scalability characteristic of DiffServ. In DARM, per-flow admission control and resource reservation, in conjunction with a novel IPv6 flow label mechanism, can be processed instantaneously in a fully distributed and independent manner at edge of network without hop-by-hop signaling. In addition, DARM is capable of reconfiguring network resource adaptively according to dynamically changing of traffic load. Through extensive simulations, the results clearly exhibit that DARM has a better overall performance comparing to the IntServ and DiffServ.
