We discuss call routing strategies for a multi-class hop-by-hop routing network like an MPLS (multi protocol label switching) network. The routing strategies are examined in view of two different objectives, load balancing and protecting service levels for calls of high bandwidths. We propose a call routing policy based on state-dependent link metrics, utilizations of the links, that extends traditional load balancing and load packing policies for path oriented call routing like call routing for virtual paths in an ATM(asynchronous transfer mode) network. We examine performance of the proposed routing policy with conventional ones.
