This paper presents a new non-greedy routing and admission control algorithm for the dynamic routing of bandwidth-guaranteed tunnels. The algorithm operates online that is handling requests which arrive one at a time without prior knowledge of the traf®c pattern. It combines the key concepts in the minimum interference routing algorithm and the algorithms developed based on theoretic competitive analysis to provide ef®cient routing. Using extensive simulations, we show that our algorithm out-performs several previously proposed algorithms on several metrics such as the acceptance rate of the tunnel set-up requests, fairness and the capability of providing priorities to tunnel requests of certain source±destination pairs in the network. q
