Abstract
A life cycle network management system for performing life cycle management of distributed network devices, each network device comprising a communication link to a central network management unit and an attached transponder configured to store life cycle data of the network device updated by said network device, wherein if the communication link between the network device and the central network management unit is at least temporarily unavailable the updated life cycle data of the network device stored in the attached transponder is read by an interrogation unit of the life cycle network management system and processed to provide a life cycle management result.
Claims18
A life cycle network management system for performing life cycle and/or maintenance management of distributed network devices of a network,
- each network device comprising a communication link to a central network management unit and an attached transponder configured to store life cycle data of the network device updated by said network device,
- wherein if the communication link between the network device and the central network management unit is at least temporarily unavailable the updated life cycle data of the network device stored in the attached transponder is readable by an interrogation unit of the life cycle network management system and processed to provide a life cycle and/or maintenance management result.
A network device of a network, said network device comprising:
- a communication link interface provided for communication between the network device and a central network management unit of a life cycle network management system of said network via a communication link and comprising
- a transponder having a data memory configured to store life cycle data of the network device updated by said network device and readable by an interrogation unit of the management system of said network.
An interrogation unit of a life cycle network management system, used for performing life cycle management of distributed network devices of a network, said interrogation unit comprising:
- a reader adapted to read life cycle data and/or communication setup data from a data memory of a transponder attached to a network device of the network and
- a transceiver adapted to forward the read life cycle data and/or communication setup data to a central network management unit of the network management system.
A network management unit of a life cycle network management system used for performing life cycle management of distributed network devices of a network, said network management unit comprising:
- a communication link interface used for communication with at least one network device of said network via a communication link and
- a transceiver adapted to receive life cycle data and/or communication setup data of the network device from an interrogation unit of the network management system if the communication link between the network management unit and the network device becomes at least temporarily unavailable.
A method for performing life cycle management of distributed network devices of a network by a life cycle network management system of the network,
- the method comprising the steps of:
- monitoring a communication link between a network device and/or network device module of the network and a central network management unit of the life cycle network management system;
- reading by an interrogation unit of the life cycle network management system life cycle data of the network device and/or communication setup data from a data memory of a transponder of said network device and/or network device module if the communication link between the network device and/or the network device module and the central network management unit of the life cycle network management system becomes at least temporarily unavailable;
- and
- forwarding the read life cycle data and/or communication setup data by the interrogation unit to the central network management unit of the life cycle network management system for evaluation of the received life cycle data and/or for reestablishment of the communication link between the network device and/or the network device module and the network management unit on the basis of the forwarded communication setup data.
