Abstract
A hierarchical communication network management system is structured by a plurality of agents and sub-managers connected to lower communication networks and an integration manager connected to a higher communication network. Each of the sub-managers functions as an agent to the integration manager and functions as a manager to each agent, so that it becomes possible to employ a Simple Network Management Protocol (SNMP) between each agent and its sub-manager and between a sub-manager and the integration manager.
