DUPLICATION APPARATUS AND METHOD OF TELECOMMUNICATION MANAGEMENT NETWORK

摘要

PURPOSE: A duplication apparatus is provided to be capable of serving without interruption by updating a routing table using link state information periodically supplied from a telecommunication management network(TMN) agent and communicating with reference to the updated routing table. CONSTITUTION: A link state testing part(10) is prepared in each TMN agent and checks a link state of a corresponding TMN agent. The link state testing part(10) reports link state information to a path managing part(20) when link state information is required from the path managing part(20) provided in a TMN manager. The path managing part(20) periodically requires the link state information of the TMN manager to the link state testing part(10) and updates a routing table(30) using periodically reported link state information. An open systems interconnection(OSI) protocol processing part(40) receives the updating of the routing table(30) from the path manager(40) to communicate with reference to the updated routing table(30). The OSI protocol processing part(40) reports referring of the updated routing table(30) to the path managing part(20).
