Address resource automatic recovery method, address resource management device and network system

Abstract

The invention discloses an address resource automatic recovery method, an address resource management device and a network system, and relates to the technical field of communications. The method includes: after receiving an address recovery success message sent by a network device, collecting address configuration on the network device information, and routing configuration information on the upstream device of the network device; based on the address configuration information and routing configuration information, determine whether the address resource that needs to be recovered is recovered successfully, if so, set the recovered address resource as an idle address resource, for redistribution. The method, the device and the network system of the present invention can avoid the problem of recovery failure that may be caused by equipment reporting errors, and can ensure that the recovered address resources are idle and can be reassigned, without causing problems such as routing confusion, and increasing the number of addresses The availability of resources is guaranteed, and the possible waste of address resources can be effectively avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for automatically recovering address resources, an address resource management device and a network system. Background technique [0002] With the rapid growth of Internet access users and various terminal devices for IP address resources, the shortage of address resources has become an urgent problem to be solved in the current operator network. In a broadband IP network, edge network devices (such as BRAS devices, firewalls, etc.) are responsible for assigning service IP addresses to end users. At present, each edge network device usually manually configures fixed address blocks and address pool resources by network administrators to meet the Internet access needs of a large number of Internet users, which easily leads to uneven distribution of IP address resources and resource waste. The existing smarter method is triggered by edge network devices, dynamically...

Problems solved by technology

However, if the device feeds back the recovery success message, but in fact the device fails to delete the configuration or revoke the route advertisement, the address resource manager will redistribute the recovered address pool to other devices, which will cause configuration and routing confusion, resulting in terminal users being unable to access the Internet, and , the address resource manager lacks an active verification mechanism for address recycling, and completely depends on the judgment of the device, so the reliability cannot be guaranteed
