Abstract(in Japanese) (See Japanese page)
Abstract(in English) A method for scalable QoS guarantee, in which QoS requirements are signaled by using a protocol similar to RSVP or NSLP and are aggregated in backbones, has been developed and prototyped. The requirements are propagated to the policy server by using policy-based routing and a policy outsourcing protocol. The policy server estimates the amount of traffic and controls the bandwidth sharing among the queues (WFQs) of the backbone routers. The effect of core traffic control has been evaluated by using an L3-switch GS4000 and bursty traffic generated by the MMPP model. The results showed that, if there are many conversational video and streaming traffics, the QoS requirements of both types of traffic can be satisfied by relatively increasing the weight of the former than that of the latter in some cases.
