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.

2. The management system according to claim 1, wherein said memory is configured to store updated life cycle data relevant for sustainability, operation, maintenance, surveillance, tracking and/or for recycling of hardware components and/or software components of the network device.

3. The management system according to claim 1, wherein the life cycle data of the network device stored in the memory of the transponder is updated directly and/or indirectly by said network device itself periodically and/or event driven.

4. The management system according to claim 3, wherein an event driven automatic update of the life cycle data of the network device stored in the memory of the transponder is triggered by an event comprising one of:

an interruption of the communication link between the network device and the central network management unit,

a location change of the network device,

an operation mode change of the network device,

a change of the environment of the network device sensed by a sensor,

a power supply interruption of the network device,

an update request received from the central network management unit, and

a component change of a component of the network device.

5. The management system according to claim 1, wherein the transponder comprises an active transponder powered by at least one of a local power source and the network device.

6. The management system according to claim 1, wherein the transponder comprises a passive transponder for receiving energy from the interrogation unit for reading the updated life cycle data stored in the memory.

7. The management system according to claim 1, wherein the interrogation unit is integrated in a handheld scanner device or in a handheld smartphone device.

8. The management system according to claim 1, wherein the central network management unit has access to a central database of the life cycle network management system adapted to store life cycle data of a plurality of the distributed network devices.

9. The management system according to claim 1, wherein the interrogation unit comprises a transceiver adapted to forward automatically the updated life cycle data read from the memory of the transponder to the central network management unit to update a central database accessible by the central network management unit, in response to the communication link between the network device and the central network management unit being unavailable.

10. The management system according to claim 1, wherein the transponder comprises a memory adapted to store a set of historical life cycle data updates performed by the network device including a timestamp indicating a time when a respective update has been performed and/or a detected event having triggered the respective update.

11. 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

said communication link interface comprising a transponder having a data memory, said data memory configured to store life cycle data of the network device updated by said network device, said updated life cycle data of the network device being readable by an interrogation unit of the life cycle network management system of said network,
