Problems solved by technology

[0005] However, this improved access control method is still unable to achieve full network roaming
A user with a legitimate user identity cannot access the Internet at a location other than the user's local area network indicated by the identity identifier, that is, it is impossible to realize non-local user networking

Abstract

The invention relates to a central access control method and a central access control server for supporting IPv6 / IPv4 dual stack access. The access control method comprises the following steps of: receiving a whole network unique identity identifier of a roaming user requesting networking from a central login server, and an IP address of a client used by the roaming user; determining the IP address belonged region by using the address matching algorithm according to the IP address of the client; and acquiring an available local free account number of the belonged region according to the IP address belonged region, and allocating the acquired available local free account number to the roaming user, wherein the available local free account number is a user resource which is allocated in theIP address belonged region, can be used by the roaming user, and can access the backbone network through a local gateway.

Description

Technical field [0001] The present invention relates to the field of network communication, and more specifically, to an access control method and server supporting (Internet Protocol Version 6 / Internet Protocol Version 4) IPv6 / IPv4 dual-stack access. Background technique [0002] Currently, the IPv6 campus network construction is in full swing. Usually, the construction method of IPv6 network is to upgrade the existing IPv4 network to IPv4 / IPv6 dual-stack network by upgrading the convergence layer and core layer equipment in the existing network. With this construction mode, the original IPv4 client must also be upgraded to an IPv6 / IPv4 dual-stack client. In this case, it is necessary to develop a new authentication system for newly added users and upgrade the original user authentication system so that the client and authentication server can identify a dual-stack user, authenticate it accordingly, and take corresponding measures. Security measures. At the same time, some us...
