Problems solved by technology

In this SLAAC address allocation and formation mechanism, even under the premise of the longest network address prefix (that is, 64), due to the change of the interface ID of the user host, it is still possible to allow 2 64 A legitimate host accesses the network, which poses new problems for network access control.
At present, there is no public solution in the industry, which can control the number of accesses of IPv6 hosts assigned with network address prefixes

Embodiment Construction

[0037] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0038] A control method for IPv6 user access provided by the present invention, such as figure 2 As shown, it mainly includes the following steps:

[0039] In step 201, the AN generates a user-based IPv6 address prefix list by monitoring or recording prefix allocation messages, or the network device generates a user-based IPv6 address prefix list by obtaining the corresponding IPv6 address prefix of the user.

[0040] It should be noted that, for a network device directly assigning an IPv6 address prefix to a host computer of an IPv6 user through a Router Advertisement (RA, Router Advertisement) message of the SLAAC protocol, the AN can monitor the network device using the downlink RA message of the SLLAAC protocol, To generate a user-based IPv6 address prefix list;

[0041] When a network device assigns an IPv6 a...

Abstract

The invention discloses a control method for IPv6 (internet protocol version 6) user access. The control method disclosed by the invention comprises: an AN (Access Node) generates an IPv6 address prefix list based on users by monitoring or recording prefix distribution messages, or network equipment generates the IPv6 address prefix list based on the users by obtaining IPv6 address prefixes corresponding to the users; and the AN or the network equipment controls the host access amount of IPv6 users according to the IPv6 address prefix list and the corresponding maximum host access amount through a mode of monitoring ascending user data messages. The invention also discloses a control device for IPv6 user access. By utilizing the method and device disclosed by the invention, the control on the access amount of an IPv6 host for determining and distributing network address prefixes is realized.

Description

technical field [0001] The invention relates to data communication technology, in particular to a control method and device for IPv6 user access. Background technique [0002] With the vigorous development of the Internet, the global unicast addresses of Internet Protocol version 4 (IPv4, Internet Protocol version 4) currently used by Internet users around the world will gradually be exhausted in the foreseeable near future; The concept of Ubiquitous Network (Ubiquitous Network) and the rise of Internet of Things (Internet of Things) construction requirements, Internet Protocol version 6 (IPv6, Internet Protocol version 6) as the mainstream network layer of Next Generation Internet (NGI, Next Generation Internet) Technology is stepping into the role. [0003] Due to the introduction of the Stateless Address Auto-Configuration (SLAAC, Stateless Address Auto-Configuration) mechanism in IPv6, its address structure, address planning and corresponding allocation mechanism are qu...
