Traffic engineering (TE) is a method of managing and controlling IP networks efficiently. This paper proposes a dynamic TE architecture that provides a QoS (Quality of Service) guaranteed service in addition to an existing best-effort service in a content delivery network (CDN). This architecture selects the optimum route and server for a user request based on the load of the network and content server. It aims to guarantee the QoS and effectively use network resources by dynamic load balancing. Also in this paper, we present the results of a simulation of the effects of our proposed method.
