Abstract

IP networks have evolved into a global and commercial communication infrastructure so that traffic requiring quality of service (QoS) is introduced in addition to best effort traffic. Consequently, network providers need to manage their network resource based on service level agreement (SLA). Conventional distributed routing is not suitable for such SLA based resource management. We propose a QoS control architecture, which provides optimal resource assignment to SLA based traffic applying centralized resource management. We also propose an algorithm to determine QoS control based on resource requests.
