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.
Claims17
A hierarchical network management system, comprising:
- a plurality of agents, connected to a communication network, for managing and controlling information, respectively, of a plurality of resources;
- a sub-manager, having a predetermined agent group under management, for managing and controlling a portion of management objects of said communication network through said predetermined agent group;
- and
- an integration manager for managing and controlling all management objects of said hierarchical communication network through said sub-manager,
- said hierarchical network management system using an SNMP as a communication protocol between said agents and said sub-manager and between said sub-manager and said integration manager, respectively, and
- said hierarchical network management system having periodic collecting means for periodically collecting within said sub-manager management objects of a management range of said sub-manager through said predetermined agent group, and for posting collected information to said integration manager at a reference request of said integration manager.

A hierarchical network management system, comprising:
- a plurality of agents connected to a first communication network;
- a sub-manager connected to said first communication network and having a predetermined agent group within said plurality of agents under management;
- an integration manager connected to a second communication network and having said sub-manager under management;
- and
- a communication path for combining said first and second communication networks,
- wherein each of said agents manages and controls management objects relating to structure information and status information of each of a plurality of resources,
- said sub-manager manages and controls management objects of said first communication network through said predetermined agent group,
- said integration manager accesses said sub-manager through said communication path to thereby manage and control a hierarchical communication network structures by said first and second communication networks through said sub-manager, and
- said sub-manager includes means for functioning as an agent to said integration manager and for functioning as a manger to said agents, so that a Simple Network Management Protocol (SNMP) can be employed as a communication protocol between each of said plurality of agents and said sub-manager and between said sub-manager and said integration manager through said communication path.
6 more elements
A hierarchical network management system, comprising:
- a plurality of lower communication networks;
- a plurality of agents connected to each of said lower communication networks;
- a plurality of sub-managers connected to respective ones of said lower communication networks, each of said plurality of sub-managers having under management a predetermined agent group, within the plurality of agents connected to a respective one of said lower communication networks;
- an integration manager connected to a higher communication network and having said plurality of sub-managers under management of said integration manager;
- and
- a communication path for connecting said plurality of lower communication networks and said higher communication network,
- wherein each of said agents manages and controls management objects relating to structure information and status information of each of a plurality of resources,
- each of said sub-managers manages and controls management objects of a respective one of said lower communication networks through the agent group under management of said sub-manager,
- said integration manager accesses said sub-managers through said communication path to thereby manage and control management objects of a hierarchical communication network structured by said higher communication network through said plurality of sub-managers, and
- said each of said sub-managers includes means for functioning as an agent to said integration manager and for functioning as a manager to said agents, so that a Simple Network Management Protocol (SNMP) can be employed as a communication protocol between each of said sub-managers and said integration manager through said communication path.
7 more elements
A system for hierarchically managing a communications network, comprising:
- a plurality of resources;
- a plurality of agents, connected to the communications network, for managing management objects of respective ones of said plurality of resources;
- a sub-manager for managing, through management of a predetermined group of agents within said plurality of agents, a portion of the management objects of said plurality of resources, said sub-manager communicating with said plurality of agents using a simple network management protocol;
- an integration manager for managing, through said sub-manager, all of said management objects of said plurality of resources;
- a communications path connecting said integration manager to said sub-manager, said integration manager communicating with said sub-manager along said path using a simple network manager protocol;
- and
- collecting means for periodically collecting within said sub-manager, through said predetermined group of agents, management objects lying in a management range defined for said sub-manager, and for posting to said integration manager information including said collected management objects in response to a reference request issued from said integration manager.
4 more elements
A hierarchical network management system, comprising:
- a first communications network;
- a plurality of agents connected to said first communications network;
- a plurality of groups of resources, each of said plurality of agents managing management objects of a respective group of said plurality of groups of resources;
- a sub-manager, connected to said first communications network, for managing, through management of a predetermined group of agents within said plurality of agents, management objects of resources being managed by said predetermined group of agents, said sub-manager communicating at least with said predetermined group of agents through a simple network management protocol;
- a second communications network;
- a communications path for connecting said first and second communications networks;
- an integration manager, connected to said second communications network, for managing said sub-manager, said integration manager communicating with said sub-manager through said communications path using a simple network management protocol and cooperating with said sub-manager to manage a hierarchical communications network which includes said first and second communications networks;
- and
- means, within said sub-manager, for functioning as an agent to said integration manager and for functioning as a manger to said predetermined group of agents.
6 more elements
A hierarchical network management system, comprising:
- a plurality of lower-level communications networks;
- a plurality of sets of agents, each set of agents connected to a respective one of said plurality of lower-level communications networks, with the agents in each set of agents managing management objects of respective ones of a plurality of resources;
- a plurality of sub-managers connected to respective ones of said lower-level communications networks, each of said sub-managers managing, through management of a predetermined group of agents within the set of agents connected to the lower-level communication network to which said each sub-manager is connected, management objects being managed by said predetermined group of agents, each sub-manager communicating with at least the predetermined group of agents being managed by said each sub-managers using a simple network management protocol;
- a higher-level communications network;
- a communications path for connecting said higher-level communications network to said plurality of lower-level communications networks;
