Embodiment
The present invention need solve that auto AP can not divide into groups automatically and the problem of packet configuration, has therefore proposed in the AP that divides into groups, to select main AP (MasterAP) to carry out grouping management, and the technical scheme through the AP equipment in the AC unified management network.
The present invention proposes the group management method of a kind of AP, be applied to comprise in the network system of an AC and its a plurality of AP that control, numerous auto AP is joined in corresponding group automatically, realize the group administrative mechanism of AP.
As shown in Figure 3, the schematic flow sheet of the group management method of a kind of AP that proposes for the present invention specifically may further comprise the steps:
Step S301, a plurality of AP are divided into groups; There is a main AP in each AP group; This main AP has fixed configurations in this AC, AC is provided with the configuration information and the descriptor of each AP group, and notifies main AP in residing AP group, to broadcast descriptor according to preset rule.
Need to prove that said fixed configurations refers to that specifically an AP has set sequence number (Serial-ID) in AC here, the AP name, information such as AP-group information, and can not change because rolling off the production line operation on this AP.
Wherein, AC divides into groups a plurality of AP, is specially:
Each AP that is in the identical AP group that AC distributed belongs in the identical virtual LAN VLAN.
It is to be noted; Above-mentioned preset rule can be adjusted according to concrete scene needs; This main AP of moment indication that in self residing AP group, carries out descriptor broadcasting at the main AP of needs carries out the broadcasting of descriptor; Such moment comprises that the AP creation is need be for each AP among this AP unified when carrying out being provided with of descriptor and configuration information after accomplishing, and also comprise as the AC discovery AP that do not divide into groups, and this AP that do not divide into groups is when meeting some requirements; Specify as follow-up shown in Figure 4, no longer be repeated in this description at this.
Step S302, AC send the configuration information and the descriptor of corresponding AP group according to the download request of main AP to main AP.
Each AP that step S303, AC receive in the network system sends the LWAPP control messages that comprises descriptor, and judges the transmission types of LWAPP control messages.
When AC judges that the transmission types of LWAPP control messages is broadcasting, execution in step S304;
When AC judges that the transmission types of LWAPP control messages is clean culture, execution in step S305.
Step S304, AC abandon the LWAPP control messages.
Step S305, AC mate the descriptor of the descriptor that is comprised in the LWAPP control messages and each AP group, and will mates the configuration information that consistent AP organizes and send to the pairing AP of LWAPP control messages.
Further, in concrete application scenarios, based on above-mentioned technical scheme; AC among the present invention also has the measuring ability that AP divides into groups, and is based on this, as shown in Figure 4; A kind of handling process that detects behind the AP that do not divide into groups for the present invention proposes specifically may further comprise the steps:
Step S401, AC detect in the network system whether have ungrouped AP in preset sense cycle.
When AC finds to have at least one ungrouped AP in the network system in preset sense cycle, execution in step S402;
When AC does not find that in preset sense cycle at least one ungrouped AP of existence is anti-in the network system, circulation execution in step S401.
Step S402, AC judge whether ungrouped AP identifies and do not add grouping.
When AC judges that ungrouped AP does not have sign not add grouping, execution in step S403;
When AC judges that ungrouped AP sign does not add grouping, execution in step S405.
Step S403, AC judge whether the AP quantity of having reached the standard grade in the current network system surpasses the preset AP amount threshold of reaching the standard grade.
When AC judges that the AP quantity of having reached the standard grade in the current network system not have to surpass the AP that presets and reaches the standard grade amount threshold, execution in step S404;
When AC judges that the AP quantity of having reached the standard grade in the current network system is reached the standard grade amount threshold above preset AP, execution in step S405.
Step S404, AC send the LWAPP message of clean culture to main AP, make main AP interval according to the preset airtime, and the LWAPP control messages of the descriptor that comprises corresponding AP group is sent in broadcasting in self residing VLAN.
In concrete application scenarios, main AP broadcasting in self residing VLAN is sent after the LWAPP control messages of the descriptor that comprises corresponding AP group, and this method also comprises:
The AP that receives the LWAPP control messages judges self whether there is descriptor that AC issues or through the accessed descriptor of other LWAPP control messages;
Self there is descriptor that AC issues or, then abandons the LWAPP control messages if AP judges through the accessed descriptor of other LWAPP control messages;
Self there is not descriptor that AC issues or, then preserves the descriptor that is comprised in the LWAPP control messages if AP judges through the accessed descriptor of other LWAPP control messages.
Further, after AP preserved the descriptor that is comprised in the LWAPP control messages, method also comprised:
When AP judged the configuration information self do not have corresponding AP group, AP sent the LWAPP control messages of the descriptor that comprises self pairing AP group to the AC clean culture;
AP receives the configuration information of the corresponding AP group that AC returns, and carries out the configuration of self according to configuration information.
Step S405, AC abandon ungrouped AP is handled.
Need further be pointed out that, in the technical scheme that the present invention proposes, also further comprise the backup flow process, i.e. disaster tolerance strategy specifically comprises:
To be main AP select one to be equipped with AP according to preset selective rule in corresponding AP group to AC, when main AP breaks down, launches fully AP as the main AP of corresponding AP group, and when being equipped with AP and being upgraded to main AP, select the next AP of being equipped with.
Compared with prior art, the present invention has the following advantages:
Through using technical scheme of the present invention, can realize AP is joined in the respective packets automatically, simplified the process of network configuration, and, realized the grouping of AP is managed automatically, make the AP management simpler, efficient.
In order further to set forth technological thought of the present invention, combine concrete application scenarios at present, technical scheme of the present invention is described.
The roughly operating mechanism of this programme is following: in the AC+FITAP network environment, will join automatically with a plurality of AP that the auto ap mode is reached the standard grade in the respective packets, and then just can be according to grouping management AP.
As shown in Figure 5, the AP at first AC configuration is hoped to add mutually on the same group must be in identical VLAN, with the direct-connected switch of AP on divide VLAN or use switch physically to separate, on the same group AP not separately.
Simultaneously on AC, set up a plurality of AP and divide into groups according to actual networking demand, i.e. AP-group, each divides into groups own description information is all arranged, with this foundation as the AP grouping.
In order to organize interior management, AC has selected a Master AP in each divides into groups, and Master AP is except being fixedly not have other requirements the AP, and first is in the AP with fixed configurations of running status in also can thinking to organize.About the explanation of fixed configurations as previously mentioned, in this no longer repeat specification.
After the MasterAP successful operation,, will in VLAN, broadcast the description information that obtains from AC with particular message if receive the broadcast announcement that AC sends; Other AP that reach the standard grade with the auto pattern are mutual with specific message format with AC after this description being saved in this locality; Tell AC with the description information of oneself preserving, AC puts it in the corresponding grouping through the description information of each AP.And then the configuration distributing in will organizing is to the AP in all groups.
Based on above setting, as shown in Figure 6, technical scheme proposed by the invention specifically may further comprise the steps:
Step S601, AC divide into groups to each AP in the network, and are definite configuration information of each AP group and descriptor.
On AC, set up the good AP grouping AP-group that needs, in each divides into groups, can independently dispose corresponding information as required, like RRM information, radio type etc.
In addition, need the descriptor of configuration groups, i.e. description information, as the foundation of dividing into groups, the description of each group needs difference.
All must have a main AP in each divides into groups, this AP can not select the auto pattern, must adopt fixedly ap mode, promptly in AC, has configured sequence number (Serial-ID), AP name, AP-group information.
The main AP in each AP divides into groups, remaining AP can reach the standard grade through the auto pattern.
Can be after step S602, the Master AP successful operation from AC download group configuration information and description information, Master AP downloads and preserves description.
After receiving the particular message of AC, if receive the notification message that AC sends, then can adopt specific LWAPP control messages form (LWAPP-des) in VLAN, to broadcast this description information, message format is as shown in Figure 7.
Wherein T is the self-defined message type, has preserved the description information that Master AP downloads from AC in the E.
This message adopts the broadcasting packet form to send, if AC receives this message, finds that MessageType is T, and is broadcast, then abandons.
If the AP in the same VLAN receives this message; Find that Message Type is T, at first confirm whether oneself to exist description information, if existence and this description information do not obtain through LWAPP-des; But AC issues; Perhaps exist and obtain, but description is consistent, then abandons this message through LWAPP-des; Otherwise take out the description information among the E, be saved in this locality.
In the application scenarios of reality, this message does not need AP to reply.
No matter be the AP that the auto mode is reached the standard grade, or the AP of manual configuration, if obtained description information from AC, then can not handle the description information of LWAPP-des message again in the back of reaching the standard grade.
The AP that step S603, other employings auto pattern are reached the standard grade if find self not have group information, will send clean culture LWAPP-des message to AC after employing LWAPP-des mode obtains descriptor.
After AC received this message, inspection Message Type was T, and is unicast messages; Then take out the description information in the message, the description with each group that has configured compares then, if consistent; Then this AP is joined in the respective sets, and group information is responded to AP.
Simultaneously, AC is with the configuration information in this group, and like rrm information, radio-frequency information etc. are handed down to AP according to normal LWAPP form form.
In the application scenarios of reality, possible other auto AP causes adding in the respective sets because the busy or other reasons of network is not received the broadcasting LWAPP-des message of Master AP, and this problem is controlled solution by AC.
AC is (sense cycle in a period of time; Be designated as time1) find to also have part A P not add any group and these AP not identify them and do not add grouping; The auto AP number＜=N of while download version (N is the threshold value of the AP of while download version); Then send clean culture LWAPP-des message, tell that Master AP needs the adding group in addition, still but the AP of not adding group exists to all Master AP.The Message Type of this LWAPP-des is T0.
Need be pointed out that further that in technical scheme of the present invention, AC can also have other controlled function, whether open the function that AP adds grouping automatically as controlling, acquiescence is opened, and all joins in the AP-group1.AC can be that this AP increases by two signs after AP reached the standard grade: the one, and description information, the 2nd, grouping information, for example, group character is that 0 this AP of expression will not be added into any grouping.
Master AP responds replying of this message of AC after receiving that Message Type is the LWAPP-des message of T0.To in a period of time, (airtime is interval, is designated as time2) in VLAN, broadcast LWAPP-des message simultaneously according to above-mentioned mode shown in Figure 7.
If AC is the (upper limit time threshold of sense cycle in a period of time; Be designated as time3); There is not adding group of auto AP in discovery; And these AP do not identify them and do not add grouping, but simultaneously this AP during this period of time the number of times of Up/Down surpassed restriction thresholding M, then can not notify MasterAP to carry out corresponding actions.
It is to be noted; In order to realize the disaster tolerance protection of system; After in auto AP adding group in whole group except Master AP; Can also exist at least one the backup AP (Backup AP), under the situation that Master AP breaks down by Backup AP as Master AP, take over the work of Master AP; Select simultaneously the Backup AP that makes new advances again, guarantee the operate as normal of whole group with this.The foundation of selecting can be the mac address of AP, and minimum is elected, when having Master AP, has the AP of littler mac to add grouping, then can not reselect.
In the operation of reality, handle MAC Address, other can realize that the mode that backs up the AP selection also should belong to protection scope of the present invention.
