Problems solved by technology

However, due to the performance limitations of existing equipment, such as figure 1 As shown, community users and group customers need to use different broadband access servers (BRAS, BroadbandRemoteAccessServer). The time is night and day respectively, resulting in the tidal effect of IP address utilization between community users and group customers. , so that the DHCP server does not reclaim the idle address segment in time, which will affect the allocation of the DHCP address segment to the BRAS applying for the address segment, and will also cause a waste of idle IP addresses in the BRAS

Embodiment Construction

[0029] In the embodiment of the present invention, when the BRAS detects an idle IP address, it obtains the idle rate of the address segment where the idle IP address is located, and when it is determined that the idle rate exceeds a first threshold, marks the address segment as ready to be recycled, When receiving an online application from a new client, the idle IP address in the address segment that is not marked as ready to be recycled is allocated to the new client preferentially.

[0030] Here, the IP address may be an IPv4 address or an IPv6 address, etc.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] The embodiment of the present invention realizes a kind of IP address management method, such as figure 2 As shown, the method includes the following steps:

[0033] Step 201: BRAS detects idle IP addresses;

[0034] Specifically, the BRAS detects a DHCP release (Re...

Abstract

The invention discloses an IP address management method. When a BRAS detects an idle IP address, it obtains the idle rate of the address segment where the idle IP address is located, and when it is determined that the idle rate exceeds a first threshold, the address segment Marked as ready to recycle, when receiving an application from a new client to access the Internet, the idle IP address in the address segment that is not marked as ready to recycle is preferentially allocated to the new client; the invention also discloses an IP address management devices and systems.

Description

technical field [0001] The invention relates to computer network technology, in particular to an IP address management method, device and system. Background technique [0002] Today, with the rapid development of science and technology, network technology is also undergoing rapid changes. Nowadays, the network plays an increasingly important role in users' lives, and more and more users are using the convenient network. However, due to the performance limitations of existing equipment, such as figure 1 As shown, community users and group customers need to use different broadband access servers (BRAS, BroadbandRemoteAccessServer). The time is night and day respectively, resulting in the tidal effect of IP address utilization between community users and group customers. , so that the DHCP server does not reclaim the idle address segment in time, which will affect the allocation of the DHCP address segment to the BRAS applying for the address segment, and will also cause a w...
