Embodiment Construction
[0053] The core idea of the present invention is to extend the existing LLDP protocol so that it can carry the IP address identifying the network resource, either IPv4 address or IPv6 address. By expanding the spread of LLDP packets throughout the network, each LLDP-enabled network device can save the IP address information of its neighbors in the MIB; the network management system selects a network device as the seed network device , by reading the IP information in the MIB of the seed network device, the IP address of the network device connected to the seed network device can be obtained, and then the device adjacent to the seed device can be searched step by step, and finally obtained in the network Multiple network device resources, and then draw a complete network topology map.
[0054] The present invention provides a method for discovering network resources and topology, which is applied to a system including an IPv6 network or an IPv6 / IPv4 dual-stack network. The sy...
