Patent ID: 7167450

Claim:
A network management method performed in a communication network system comprising a plurality of nodes and a network management system, the method comprising steps of: generating software including a control program that commands a first node to transfer at least one first packet from the first node to a second node and to collect at least one first network control item of the first node, and commands the second node to transfer at least one second packet from the second node to the network management system and to collect at least one second network control item of the second node at the network management system; transferring at least one third packet appending the software including the control program from the network management system to the first node; receiving the third packet from the network management system at the first node; generating the software including the control program from the third packet; storing the first network control item of the first node based on executing the software; transferring the first packet appending the software and the first network control item from the first node to the second node; receiving the first packet from the first node at the second node, generating the software including the control program from the first packet, storing the second network control item of the second node based on executing the software, transferring the second packet appending the software, the first network control item and the second network control item from the second node to the network management system, receiving the second packet from the second node at the network management system, and managing the first node and the second node based on the first network control item and the second network control item, wherein the first network control item and the second network control item detect the packet received from the second node.
