As the OSI protocols come to be widely adopted in various communication systems, the testing of OSI protocol implementations becomes important. In this testing, the interoperability testing is performed to examine the interconnectability which cannot be checked in the conformance testing. In this paper, we propose the Intelligent OSI Protocol Monitor which observes PDUs (Protocol Data Units) exchanged between OSI system and analyzes the protocol behaviors as well as the PDU format according to the protocols of OSI 7 layers. This monitor is effectively used to observe the actual communication for a long period and to detect protocol errors which cannot be detected by the conformance testing. This paper describes the detailed design of the Intelligent OSI Protocol Monitor and shows how it works for actual OSI protocols.
