Service routing across different MPLS and access networks domains is a critical issue in next generation networks. In spite of being a de facto inter domain routing standard, BGP can not fulfill the inter domain traffic engineering needs and it does not take into account service metrics, which results in the low routing efficiency of BGP. We set up a system model by decomposing the problem. Based on the model, we set up a service network reduction algorithm. At the initial stage we use a grid service instance to map service paths of different MPLS domains, then we construct service network graph, and set up index for service routing based on ontology. At the last stage, we get a single service metric to set up service routing by applying the service ontology metric function.
