METHOD AND COMMUNICATION SYSTEM FOR PROCESSING STATE INFORMATION IN A MANAGEMENT NETWORK HAVING DIFFERENT MANAGEMENT LEVELS

摘要

According to the invention, state information is transmitted between an agen t (AG) of a management level (B, C) and at least one manager (MA1, MA2) of a next higher management level (A, B). A request message (staAS) is sent by th e manager (MA1, MA2) to the agent (AG) for executing information matching. Sta te information regarding deviations from a normal state are checked by the agen t (AG) and changes in state information are sent to the manager (MA1, MA2) in one or several successive messages (staCN). Information matching is conducte d only when changes in state information exist so that deviations from normal state are informed to the manager. Consequently, all state information regardless of whether said information has changed or not is not automatical ly transmitted to the manager. This results in reduced information flow between the agent and the manager and represents a considerable gain for the manager especially in the case of a plurality of managed objects.
