  abstract = {Service providers such as an Autonomous System (AS) are controlled by a network overlaid on top of the underlying network which aims to optimize a certain metric value, reduce cost, and increase the performance or efficiency of network traffic flow. Normally, the service gateways are placed on the boundaries of an AS for all inter-domain traffic to pass through to extra domain networks. In cases where the time constraint is crucial as in interactive traffic flow transmissions, the service gateways have more impact on the performance. So that end-to-end paths have to pass, at least, one of the service gateway locations to carry the traffic flows from source to the destination. Traffic Engineering requires efficient tools to optimize network performance and traffic delivery. This paper covers the canalization of performance problems found in IP networks, to maximize the admitted traffic flow transmission without delay violations. The solution approach can be divided into two sub-problems. The first applies the placement algorithms to determine the gateway locations; the second applies the selection algorithms to dynamically route flows via one of the pre-determined gateways in real-time. The results indicate that the placement locations will perform best when the path length to the gateway and the current residual bandwidth are both taken into consideration which has higher priority to the first one.},
