4.1 junction point device management function
The junction point device management is the WLC important component, the system may provide to functions and so on AP parameter establishment, condition examination, system upgrade, load stabilization, AP survey.
The system may act according to AP each establishment, establishes the same page, to AP which uses carries on the global administration on WLC.
The system provides the AP status messages function carries on the classified examination including the single AP status messages’ examination as well as the basis different condition to AP. In the AP tabulation selects AP, the system will demonstrate this AP including the current condition basic information. In the condition tabulation chooses a condition, the system will be under this condition AP to demonstrate completely.
The AP system upgrade’s function is in issued when new AP edition, may place the AP promotion package on the local management system management system, carries on the unification promotion through the promotion function to or many AP.
The AP load stabilization is for in the identical ESS different AP operating duty. When the user receives on some AP through the wireless note company, the system the information which will deliver through AP will increase all AP load information which or the renewal system will manage, when the user will request will register, the system will possess simultaneously may connect AP the load information transmission for the subscriber’s premises. Chooses AP by the user to carry on the connection, achieves the good band width and the speed. AP load stabilization’s process as shown in Figure 2.
The AP survey function is refers to may use some AP to carry on the scanning, surveys nearby all AP, then gives the system these AP information transmission, the system the information which manages these information and AP itself carries on the analysis, by determined that which don’t have management AP, then option processing. AP survey process as shown in Figure 3.
4.2 user management function
Sets up the wireless local area network’s primary purpose is to cause the user convenient, the free access network resources, therefore a user’s management foot wireless local area network management system management system essential important component. The wireless local area network management system management system has provided the nimble user management function. The manager may increase the different user group, increases the user in the different user group, realizes the user group’s management and user’s tube jade.
To some user group, the manager may assign the different jurisdiction for the user group, limits in the group the user to visit Intranet or to visit Internet or both may visit, simultaneously may also establish the more concrete access rule, for example may limit in the group the user to be possible to visit or cannot visit certain websites. The system has provided many kinds of user authentication way, may assign the user for the user group the authentication way.
Regarding user’s management, when founds a new user, may assign the user group for it, may also not assign, namely a user may belong to a user group, may also not belong to any user group. If the user does not belong to any group, may assign for it to visit Intranet and the Internet jurisdiction, establishes the more concrete access rule, assigns the authentication way. If the user belongs to some group, this user will follow the respective group the access authority, the access rule as well as the authentication way, but may increase the more concrete access rules for this user. Saves in the user management, the system also provides the freeze user the function. If discovered that some user carries the virus or has the legal act, the manager may this user freeze. In freeze period, this user will not be able to carry on any network visit. The manager may act according to the special details to assign the freezing time during freeze, or does not assign, does not have when the question until the confirmation manual restores this user again the jurisdiction.
4.3 monitor functions
In order to guarantee that the wireless local area network’s normalcy and the stability, must understand the entire wireless local area network system’s movement condition, so that the stitch in time appears question. The wireless local area network management system management system has provided the comprehensive monitor function, can real-time understand AP the condition, the online user’s condition as well as the entire management system management system movement condition. In the AP tabulation, the system marks AP with the different icon the different condition, the manager may act according to the icon to understand that very easily AP the condition, regarding has warning AP, the manager may examine the system record diary information according to the AP information, thus understood appears question and stitch in time. To the online user’s condition, the system provides the following information the track: The user name, the IP address, the MAC address, the user use AP SSID, the network current capacity.
