Embodiment Construction

[0018] The basic principle of the scheme of the present invention: the problem existing in multiple portal servers at present: when the terminal accesses any AP1, the redirection address is returned, such as cwp.gwn.cloud, the terminal is redirected to cwp.gwn.cloud, after the dns request is initiated , hijack to AP1, return the address of AP1, after requesting to complete the portal page, connect the terminal to other AP2 (not in the same subnet as AP1), the terminal may not send a dns packet, causing the terminal to be on AP2, thinking that cwp.gwn .cloud corresponds to the address of AP1, and the portal push cannot be completed. At this time, the address of cwp.gwn.cloud is uniformly resolved to 1.1.1.1, and a rule is set on all APs to redirect the destination address of 1.1.1.1 to itself. The present invention configures a plurality of network access devices in the network access network, and the resources and configurations of these devices can be synchronized, so that th...

Abstract

The present invention discloses a distributed Portal access method, the method mainly comprises following operations: step a: After a client accesses an AP device in a network access device group, determining whether the client has a network access permission, and if the client has network access permission, allowing the client to access an external network, if the client has no network permission, then the client sends an http request to the external network; step b: redirecting to a portal server, returning a redirect message by the portal server, accessing the portal server by the client according to the redirected message and obtaining a portal page for client authentication; step c: after passing client authentication, sending information of the client authentication to other AP devices in the network access device group through broadcast format. The method has the portal server and an authentication server function embedded in the AP device, namely, the portal push and authentication can be completed in the network access device, thereby greatly reducing concurrent pressure of the server and improving network access efficiency.

Description

technical field [0001] The invention relates to the field of network security access, in particular to network communication technology for access. Background technique [0002] With the development of broadband wireless access technology and the popularization of mobile terminals, the security control and operation management of network resources have become the focus of attention, and Captive Portal came into being. In the existing centralized wireless coverage solution, there is a risk that the Captive Portal cannot be used due to a controller failure, and in a high-concurrency authentication scenario, the portal server and the authentication server are under heavy pressure. For these problems, there is currently no comparison Perfect feasible solution. For example: in public places, airports, shopping malls and other areas, WIFI service providers provide free services to individual users to realize the accumulation of traffic and data, and realize it in the form of load...
