A ROUTING POLICY DESCRIPTION LANGUAGE FOR THE INTER-DOMAIN ROUTING PROTOCOL

The inter-domain routing protocol (IDRP) is a strategic routing contro l protocol designed for wide use in OSI and the Internet. In IDRP, it is possible to impose fine route control reflecting local policies reg arding the operation and management of networks; however, the configur ation becomes extremely complicated with an increased number of polici es. In this paper, a language is designed to describe routing control policies and various necessary knowledge configurations. A tool is ins talled for proper configuration from the policies and knowledge descri bed by the design language. All knowledge necessary for the configurat ion is described by the ''is-a'' relation, and an inference engine is established based on the transitive law and succession relation. In ad dition, descriptions of framepolicies are made possible by using the ' 'if-then'' rule. (C) 1998 Scripta Technica.
