IP address distributing management method for wideband access equipment

Abstract

The user IP address distributing management method for wideband access equipment includes configuring multi-web section IP address for one or more Super Vlan of wideband access equipment; the wideband access equipment responding the IP address request of the Super Vlan user; applying one idle address from the configured multi-web section IP address and returning the applied address to the user; or refusing the user's request in case of being incapable of obtaining idle address form the multi-web section IP address; and releasing the user's off-line address as the idle address. The IP address distributing method is transparent to the user and the routing configuation under wideband construction and has extremely raised IP address utilization. The method can simplify the expansion of capacity in wideband construction, is favorable to backup of the new service, and may be used widely in wideband communication.

Description

Technical field: [0001] The invention relates to the field of broadband network access equipment, in particular to a method for allocating and managing user IP addresses of broadband network access equipment. Background technique: [0002] In the planning of broadband network construction, the allocation and management of IP (Internet Protocol) addresses is a very critical issue. Generally, broadband access devices use DHCP relay (Dynamic Host Configuration Protocol relay), DHCP client-proxy (Dynamic Host Configuration Protocol client proxy) or local address pool methods to allocate IP addresses to access hosts to achieve IP address centralized management. In order to realize the isolation of communication between access users, vlan (virtual local area network) technology is used to divide each user into a separate broadcast domain, so that users cannot communicate with each other; at the same time, super vlan (super virtual local area network) is adopted ) technology to c...

AI Technical Summary

Problems solved by technology

During the peak period of surfing the Internet, the maximum number of simultaneous access users in Super vlan1 is 61, and the 62nd user will not be allowed to access because the IP address cannot be allocated; while Super vlan2 may have just allocated a number, there are fewer users, and there are still There are a large number of free IP addresses, but due to the current address allocation method, it is impossible for users of Super vlan1 to be allocated to addresses in Super vlan2, which leads to insufficient utilization of the precious IP address resources of access devices, and also limits The maximum number of concurrent users accessing the system at the same time

[0006] 2. Not conducive to supporting emerging businesses

In this application of allocating IP addresses according to business, address allocation based on Super vlan can no longer meet the requirements, and it cannot quickly and effectively support specific services

[0008] 3. Complex network planning and IP address management

[0009] Since each expansion needs to consider the address allocation and range and how to meet the maximum number of concurrent access users in the Super vlan, the planning of the broadband network becomes very complicated, and multiple IP address divisions lead to a large number of IP addresses. There is no way to use address fragments, and the dynamic IP address allocation of the system should be transparent to users. Access users do not care about the IP address and network segment they use when accessing, and can quickly access and access network resources. is the greatest demand of users
