Design and implementation of network management system splice/NM based on scripted operations

To provide reliable Internet service, in addition to a computer operating as a server, it is necessary to have a steady running gateway for connection between networks. If a problem arises with this equipment, early and fast recovery service is essential. However, due to fast Internet expansion and increasing complexity of problems, at the current stage problem management is neither fast nor accurate, which contributes to overload of network managers. The SPLICE/NM system described in this article was designed to assist managers by automating the recovery operations. The main point of SPLICE/NM is that managers can use a programming language to describe operations performed at their terminals, and the work automation is achieved by recording scripts generated by managers. In addition to techniques aimed at automation of problem management, the article describes design methods suitable for Internet applications of SPLICE/NM.
