Based on said system framework, the schematic flow sheet of the data processing method that the embodiment of the present invention provides can be as shown in Figure 4.
As shown in Figure 4, the schematic flow sheet of a kind of data processing method providing for the embodiment of the present invention, can comprise the following steps:
Step 401, data center monitor AC.
Concrete, in embodiments of the present invention, data center can by with AC between heartbeat is connected each AC in system is monitored, comprise that whether AC load is over threshold value, the AC machine etc. of whether delaying.
When step 402, the load that monitors AC when data center surpass threshold value, one or more loads that the part AP that the indication AC of this data center connects it is switched in other AC do not surpass the AC of threshold value.
Concrete, when the load that monitors certain AC when data center surpasses threshold value, in order to realize load balancing, data center can send and switch message to AC, and the part AP that indication AC connects it is switched to one or more loads and does not surpass other AC of threshold value.
Wherein, in the switching message that data center issues to AC, can carry the AP that need to switch, and the information of the target AC that switches of this AP (first switches message), also can only carry the information (second switches message) of the target AC that AP switches.
When AC receives the first switching message, can first switch message and determine the AP that need to switch according to this, and each AP target AC that need to be switched to, thereby corresponding AP is switched to corresponding target AC.Meanwhile, data center can be issued to corresponding target AC by the AP switching and user corresponding to this AP information.
For example, data center monitors AC_1 load and surpasses threshold value, data center can issue the first switching message to AC_1, and the AP1 that indication AC_1 connects it is switched to AC_2, and the load that the AP2 that it is connected is switched to AC_3(AC_2 and AC_3 does not all surpass threshold value); AC_1 receives after the first switching message, can connect according to this first switching message indication AP1 and AC_2, and AP2 and AC_3 connect; Meanwhile, data center also needs user's that AP_1 and AP_1 are connected information to be issued to AC_2, and the user's that AP_2 and AP_2 are connected information is issued to AC_3.
When AC receives the second switching message, can determine the target AC that AP switches according to this second switching message, and select part AP the AP connecting from self, switch to corresponding target AC.After AC has determined the AP switching, need to send feedback message to data center, in this feedback message, carry the AP switching, and the information of the target AC that switches of this AP, and according to this feedback information, the AP switching and user corresponding to this AP information is issued to corresponding target AC.
For example, data center monitors AC_1 load and surpasses threshold value, and data center can issue the second switching message to AC_1, and the load that indication AC_1 can be switched to part AP AC_2 and AC_3(AC_2 and AC_3 does not all surpass threshold value); AC_1 receives after the first switching message, selects part AP, and switch to corresponding target AC the AP that can connect from self, and as AP3 is switched to AC_2, AP4 is switched to AC_3.AC_1 has determined after the AP that switches and corresponding target AC thereof, to data center, send feedback message, so that data center is issued to AC_2 by self AP3 of storage and user corresponding to AP information, the user's that AP4 and AP4 are corresponding information is issued to AC_3.
Step 403, data center upgrade the AP of the AC connection of self storing and user's information.
Concrete, the indication AC of data center carries out after AP switching, also needs to upgrade the AP of the AC connection of self storing and user's information.For example, the user of AP1 and connection thereof, by being connected with AC_1, being updated to AC_2 and being connected.
In embodiments of the present invention, in the AP that the AC of data center's storage and this AC connect and user's information, can comprise the information of the backup AC that AP is corresponding, between AP and its backup AC, set up and have backup link.
In this case, when data center monitors certain AC and delays machine, the AP that the AC that data center can store according to self and this AC connect and user's information, the AP that the AC of the machine of delaying is connected and user's information are handed down to corresponding backup AC, thereby realize the machine backup of delaying.
The AP that the AC of machine of delaying connects, can by will and backup AC between backup link activate, be connected under corresponding backup AC.
For example, AP1 is connected with AC_2 with AC_1 respectively, and wherein the link between AP_1 and AC_1 is primary link, and the link between AP1 and AC_2 is backup link (the backup AC that AC_2 is AP1).When AC_1 delays machine, AP1 can, by the backup link between activation and AC_2, be connected under AC_2.When data center monitors AC_1 and delays machine, can, according to the AC of self storage and AP that this AC connects and user's letter, AP1 and corresponding user profile be issued to AC_2.
Complete after above-mentioned processing, data center can upgrade the AP of the AC connection of self storing and user's information.
Further, in embodiments of the present invention, when the link between connected certain AP of AC breaks down (as interrupted), AC can send for noticing the message of the link occurs fault between the connected AP of AC to data center, carries the information of this AC and this AP in this message.
Data center receives after this message, can be according to AC and this AC AP that connect and user's the information of the information of the AP carrying in this message, self storage, and this AP and user corresponding to this AP information is issued to backup AC, thereby realizes link backup.
Should and AC between the AP that breaks down of link (master) can activate by and backing up backup link between AC, be connected under corresponding backup AC.
For example, AP1 is connected with AC_2 with AC_1 respectively, and wherein the link between AP_1 and AC_1 is primary link, and the link between AP1 and AC_2 is backup link (the backup AC that AC_2 is AP1).When link down between AP1 and AC_1, AP1 can by activate and AC_2 between backup link, be connected under AC_2.AC_1 can send for noticing the message of the link occurs fault between the connected AP of AC to data center, so that the AP that the AC that data center stores according to self and this AC connect and user's letter are issued to AC_2 by AP1 and corresponding user profile.
It should be noted that, in embodiments of the present invention, when having new AC need to join in system, this AC only needs to set up heartbeat with data center, by the information of self, and the AP self connecting and user's information is synchronized to data center, and with system at least one AC set up transmission (being connected to form route by two layers or three-layer network can reach), realized backup and expanded.Preferably, AC can set up transmission with two AC in system, thereby forms routine cycling, completes backup expansion.
