Control unit, for the judged result according to described judging unit, if the sum of consumption of natural resource on the resource that described application traffic consumes and described AP is greater than the resources project recommended value of described AP, resource restriction is carried out to all Wifi terminals of access on described AP, makes the sum of consumption of natural resource on the resource consumption needs of described application traffic and described AP be not more than the resources project recommended value of described AP.
10. system according to claim 9, it is characterized in that, when all Wifi terminals of described control unit to access on described AP carry out resource restriction, specifically the bandwidth of all users accessed current on described AP and/or session number resource quantity are reduced according to predetermined manner.
11. systems according to claim 6 to 10 any one, is characterized in that, also comprise:
Described Wifi terminal, for after being assigned with IP address, initiate the request of focus access authentication to portal server, the request of described focus access authentication comprises user account number and password; And after AC carries out resource restriction to all Wifi terminals that described AP accesses, to carry out the speed access application after resource restriction renewal;
Portal server, for receiving the focus access authentication request of described Wifi terminal transmission and being transmitted to certificate server;
Certificate server, for prestoring user account number and the password of validated user, carries out certification based on the user account number in focus access authentication request described in the user account number prestored and codon pair and password, and sends authentication result to described AC;
Described AC, also for according to described authentication result, passes through certification in response to the user account number in the request of described focus access authentication and password, allows described Wifi terminal accessing Internet.
