ABSTRACT:
Data communications neworks may be composed of many different physical devices linked together in various layers and using various protocols for communication. The multiple physical elements that make up such communication networks or links are often supplied by diverse vendors. As a result, isolation and diagnosis of communication failures becomes an extremely difficult and cumbersome process. The present system and method simplify the process greatly by premitting a system control operator or control application program to issue generic, non-device-specific problem isolation, control or diagnostic commands to the communication neetwork by identifying the link and target node for which problem isolation and diagnosis is required. The non-device-specific commands are received first at an intermediate translation facility which retrieves communication link physical configuration data and identifies the physical components and characteristics thereof that make up that communication link to the identified target node. The translation facility then issues one or more device-specific problem determination commands on the communication link directed toward said node. It receives one or more device-specific responses from one or more physcial devices in the communication link and, responsive thereto, either issues further device-specific commands on the communication link to complete the diagnosis or issues generic, non-device-specific problem identification results as responses to the requesting control nodes' initial request.
