Method and apparatus for diagnosing problems in data communication networks

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