Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing and according to embodiment, technical scheme of the present invention is described in detail.
The application provides a kind of technical scheme of AP firmware upgrade, is applied in wlan network.AC in this wlan network need divide upgrading group in advance, unifies firmware upgrade to the AP in same upgrading group.
AC, when dividing upgrading group, by can communicate in same website, and uses the AP of same firmware to be divided into a upgrading group.In the embodiment of the present application, same website represents an internal network, situation about being connected by wide area network (as internet) is there is not in this internal network, as there are general headquarters and 2 branched structures in certain enterprise, the network includes three stations point of this enterprise so can be thought.
For the AP that the AP that can communicate in same website is in same VLAN; Or, for can AP in the VLAN of UNICOM, namely a kind of division methods is only by the AP of double layer intercommunication in same website, and use the AP of same firmware to be divided into a upgrading group, another division methods is in same website, the not only AP of double layer intercommunication, if the AP that there are three layer intercommunications, and uses the AP of same firmware to be also divided in a upgrading group.
In the application's specific implementation example by reference to the accompanying drawings, the process that AC divides upgrading group is described in detail:
It is the wlan network schematic diagram comprising a website see Fig. 1, Fig. 1.Comprise two VLAN at the wlan network of this website in Fig. 1, be respectively VLAN1 and VLAN2.Suppose AP1, AP2, AP3 and the AP4 in VLAN1, and AP5 and AP6 in VLAN2 uses same firmware; AP7 and AP8 in VLAN2 uses same firmware.
If use the first upgrading partition method, the AP of same firmware is used to be divided into one group in same website in same VLAN, then in Fig. 1, AC can divide three upgrading groups, first upgrading group comprises AP1, AP2, AP3 and AP4, second upgrading group comprises AP5 and AP6, and the 3rd upgrading group comprises AP7 and AP8.
If use the second upgrading partition method, use the AP of same firmware to be divided into upgrading group in the VLAN that can be communicated with in same website, be specially:
When VLAN1 with VLAN2 is communicated with, when the AP in AP with VLAN2 namely in VLAN1 can communicate, be divided into two upgrading groups, first upgrading group comprises AP1, AP2, AP3, AP4, AP5 and AP6; Second upgrading group comprises AP7 and AP8.
When can not be communicated with between VLAN1 and VLAN2, namely when the AP in AP with VLAN2 in VLAN1 can not communicate, be divided into three upgrading groups, first upgrading group comprises AP1, AP2, AP3 and AP4, second upgrading group comprises AP5 and AP6, and the 3rd upgrading group comprises AP7 and AP8.
The AP managed under supposing an AC is distributed in 100 VLAN of a website, and sequence number is from 1 ~ 100.So AC needs the connectivity between these VLAN of background test.The VLAN that can reach mutually is combined, therefrom gets the identical AP of firmware and merge into a upgrading group.AC from VLAN1, can test with other VLAN one by one, finally by all VLAN loop tests one time, can know the connectivity between VLAN with this.
The method of the connectedness that AC determines between two VLAN is specially:
A respectively optional AP in two VLAN of this AC in same website, an AP issues the self-defining order of manufacturer wherein, makes this AP PING another one AP, if success, determines that described two VLAN can UNICOM; Otherwise, determine that described two VLAN can not UNICOM.
Because the test of the connectivity between two VLAN is undertaken by AP, so can concurrent testing, the disposable test that can issue a large amount of VLAN of AC, to improve speed.
Divide the process of upgrading group in the same website of above-detailed, when the AP describing AC management in detail below in conjunction with accompanying drawing is in the different website, divide the process of upgrading group:
It is the wlan network schematic diagram comprising multiple website see Fig. 2, Fig. 2.In Fig. 2, AC is in website 1, and website 2 comprises VLAN1 and VLAN2, wherein, AP1 and AP2 in VLAN1, and and AP3 and AP4 in VLAN2 uses same firmware; Website 3 AP5, AP6, AP7 and AP8 comprised in VLAN1, a VLAN1 uses same firmware, and each AP in each AP in website 3 in VLAN1 and the VLAN1 in website 2 uses same firmware.
When using the first upgrading partition method, the AP that AC is associated is divided into three upgrading groups, is respectively: first upgrading group comprises AP1 and AP2 in website 2, and second upgrading group comprises AP3 and AP4 in website 2; 3rd upgrading group comprises AP5 to the AP8 in website 3.
When using the second upgrading division methods, if be not communicated with between VLAN1 and VLAN2 in website, then the AP associated with it is divided into three upgrading groups by AC, is respectively: first upgrading group comprises AP1 and AP2 in website 2, and second upgrading group comprises AP3 and AP4 in website 2; 3rd upgrading group comprises AP5 to the AP8 in website 3.
If be communicated with between VLAN1 and VLAN2 in website, then the AP associated with it is divided into two upgrading groups by AC, is respectively: first upgrading group comprises AP1, AP2, AP3 and AP4, and second upgrading group comprises AP5, AP6, AP7 and AP8.
Seen from the above description, in the application's specific embodiment, AC is when dividing upgrading group, AP in different website, namely allow to communication and use the AP of same firmware also can not be divided in same upgrading group, can to communicate in same website, and use in the AP of same firmware and belong to being divided in a upgrading group of same VLAN, belong to different VLAN can determine whether to be divided in same upgrading group according to practical application configuration.
Above-mentioned citing is only the upgrading partition method provided in the application's specific embodiment, when carrying out the division of upgrading group according to above-mentioned rule in actual applications, if when the AP data in certain upgrading group are excessive, also according to practical application, this upgrading group can be further subdivided into two or more upgrading group.
Below in conjunction with accompanying drawing, describe the process of in the application's specific embodiment, the AP in certain upgrading group being carried out to firmware upgrade in detail:
Be that in the application's specific embodiment, AC carries out the schematic flow sheet of firmware upgrade to AP in a upgrading group see Fig. 3, Fig. 3.Concrete steps are:
Step 301, AC selects an AP in upgrading group, and carries out firmware upgrade to this AP.
Step 302, the AP that this AC notice does not carry out firmware upgrade is the AP carrying out firmware upgrade that it is specified, the AP carrying out firmware upgrade this AP not carrying out firmware upgrade being associated with specify carries out firmware upgrade, after firmware upgrade terminates, restarts and is associated with this AC.
For an AP in this upgrading group, if this AP is the AP not carrying out firmware upgrade, receive AC notice for this AP specify carry out the AP of firmware upgrade time, be associated with the described AP carrying out firmware upgrade specified and carry out firmware upgrade; Carrying out after firmware upgrade terminates, when receiving the reset command that the described AP carrying out firmware upgrade specified sends, carrying out restarting and be associated with described AC.
If if this AP has carried out the AP of firmware upgrade, when other AP associate this AP, for other AP described upgrade; At the end of other AP firmware upgrades described, send reset command to other AP described, make other AP described carry out restarting and being associated with AC.
When specific implementation, the AP that AC does not respectively carry out firmware upgrade by the form notice sending AC list is the AP carrying out firmware upgrade that it is specified, and in AC list, the priority of carrying out the AP of firmware upgrade of specifying is set to the superlative degree, specific as follows:
First AC determines whether the priority of this AC is highest, if so, is set to second advanced by the priority of this AC; Otherwise the priority maintaining AC is constant.
This AC is that the AP not carrying out firmware upgrade specifies the AP having carried out firmware upgrade, and is not carried out the AP of firmware upgrade by AC list notification, carry the IP address of carrying out the AP of firmware upgrade and priority of specifying, and priority is set to the superlative degree in this AC list.
Do not carry out the AP of firmware upgrade when receiving the AC list that AC sends, upgrade local AC list, due to the AP carrying out firmware upgrade for specifying that current AC list medium priority is the highest, therefore, associate with the AP carrying out firmware upgrade that this is specified, and carry out firmware upgrade in association process.
Carry out the AP of firmware upgrade when receiving the association of other AP (not carrying out the AP of firmware upgrade), allow the association of other AP described, and firmware upgrade is carried out to other AP described, it is similar that firmware upgrade process and AC are that AP carries out firmware upgrade process.At the end of other AP firmware upgrades described, this AP having carried out firmware upgrade sends reset command to other AP described, makes other ap reboots described and is associated with on AC.
Do not carry out the AP of firmware upgrade at the end of firmware upgrade, when receiving the reset command into the AP transmission of its upgrading, carry out restarting and being connected on AC.
Step 303, this AC determines whether there is the AP not carrying out firmware upgrade in this AP group, if so, performs step 302; Otherwise, perform step 304.
Step 304, process ends.
AC determines that in this upgrading group, all AP carry out firmware upgrade all, when namely there is not the AP not carrying out firmware upgrade in this upgrading group, if this AC AP in this upgrading group carries out being set to second advanced by the priority of this AC in escalation process, then reverts to the superlative degree; Otherwise the priority maintaining this AC is constant.
The AP firmware upgrade method provided in the application's specific embodiment, makes AP firmware upgrade speed fast.Because the quantity of carrying out the AP of firmware upgrade is that multiple increases, there is a large amount of AP firmware updating at the same time the same time.If there are 2048 AP in a upgrading group, when starting to carry out firmware upgrade, AC selects an AP to carry out firmware upgrade, carries out firmware upgrade be designated as the 1st upgrading round to this AP; Afterwards, there is the AP that 2 are carried out firmware upgrade, then upgrade to two AP not carrying out firmware upgrade in this upgrading group with these two AP carrying out firmware upgrade in this upgrading group, this escalation process is designated as the 2nd upgrading round; After upgrading terminates, the AP that 4 are carried out firmware upgrade is there is in this upgrading group, by that analogy, the AP carrying out firmware upgrade in upgrading group is that Geometric Sequence increases, the wheel number of times carrying out upgrading is the number 12 of Geometric Sequence, is specially: 1,2,4,8,16,32,64,128,256,512,1024,2048.
Every AP update time is 3 minutes, needs 12 round upgradings altogether, accumulative needs 12 × 3=36 minute; And if employing tradition is from the method for AC serial upgrading, then need totally 2048 rounds upgradings, accumulative needs 2048 × 3=102 hour.
If if when considering that multiple upgrading group needs to upgrade again simultaneously, then, compared with mode of upgrading with serial, more can save a large amount of AP firmware upgrade time.
Whole net AP firmware upgrade is born by the AP carrying out firmware upgrade of substantial amounts substantially, and the processing pressure of AC is reduced greatly;
Intermediate line link on the transmission primaries of firmware between AC-AP of AP, greatly reduces the bandwidth consumption between AP and AC, cost saving, improves speed.
Below can intercommunication with VLAN1 and VLAN2 in Fig. 1, and during AC use second way division upgrading group, the upgrading group divided, if each AP firmware upgrade in the first upgrading group (AP1, AP2, AP3, AP4, AP5 and AP6) is example, describe AP firmware upgrade process in the application's specific embodiment in detail.
The first step, AC selects AP1 in the first upgrading group, and carries out firmware upgrade for AP1.
In this step, AC selects AP1 also to upgrade to AP1, and in actual applications, AC can arbitrary AP in Stochastic choice first upgrading group carry out firmware upgrade to it.
It is as follows that AC is that AP1 carries out the process of firmware upgrade:
1, AP1 sends to AC and joins request (Join Request), and carries the firmware version number of AP1;
2, AC sends to AP1 and adds response (Join Response), and adds in response the firmware version number of carrying AC this locality at this;
3, AP1 sends mirror image data request (Image Data Request) to AC, and carries its firmware identifier expected;
If 4, AC determines this AP of upgrading, mirror image data response (Image DataResponse) will be sent to AP, carry some information of AP firmware, comprise byte-sized, HASH completeness check code and SUCCESS reason code;
5, AP1 asks firmware file by Image Data Request message cycle to AC;
6, AC is by the segmentation of AP firmware file, and feeds back to AP1 by Image Data Response one by one;
7, AC can send Reset Request message remote reboot AP (optional) to AP1.
Second step, after AP1 upgrading terminates, determines whether the priority of this AC is highest, if so, is then set to second advanced by the priority of this AC; Otherwise, do not process.
When the priority of AC is for highest (priority value is 1), can be set to second advanced (priority value is 2), also can being set to other priority values outside the superlative degree, in order to ensure that AP firmware upgrade is connected on this AC after restarting, can being set to second advanced.
When the priority of AC is not highest, its priority can be kept constant.
3rd step, AC selects an AP do not upgraded (AP2), and the address of AP1 and priority are notified AP2 with the form of AC list.
Wherein, the priority of AP1 is set to the superlative degree.
AC is after terminating for AP1 upgrading, and Stochastic choice AP in the AP do not upgraded in the first upgrading group, as AP2.
4th step, when AP2 receives the AC list of AC notice, by this AC list update in local AC list, when determining the highest equipment variations of AC list medium priority, sending to the AP1 that priority is the highest and joining request.
AC list is the AC table that the IP address of multiple AC and priority groups are woven in internal memory by AP.AP can make reference according to the priority of each AC in this table, loading condition, capacity, connects from main separation AC.
If AP is in running, find that the AC list of oneself has renewal, and the priority of certain AC is 1 (the highest), so it will be abandoned current AC and connects, then connect the highest AC of this priority, namely the present embodiment AP2 finds that the priority of AP1 in list is the highest, then can connect AP1.
5th step, when AP1 receives joining request of AP2, carries out adding response, and carries out firmware upgrade for AP2.
AP1 is that AP2 carries out the process of firmware upgrade and AC to be that AP1 carries out the process of firmware upgrade similar, specific as follows:
1, AP2 sends to AP1 and joins request (Join Request), and carries the firmware version number of AP2;
2, AP1 sends to AP2 and adds response (Join Response), and adds in response the firmware version number of carrying AP1 this locality at this;
3, AP2 sends view data request (Image Data Request) to AP1, and carries its firmware identifier expected;
4, AP1 sends view data response (Image Data Response) to AP2, carries some information of AP firmware, comprises byte-sized, HASH completeness check code and SUCCESS reason code;
5, AP2 asks firmware file by Image Data Request message cycle to AP1;
6, AP1 is by the segmentation of AP firmware file, and sends to AP2 by Image Data Response one by one.
6th step is after AP2 firmware upgrade terminates at AP1, sends reset command to AP2.
7th step, AP2 is restarted, and is rediscovered AC, be associated with the AC that AC list medium priority is the highest after receiving the reset command of AP1 transmission.
AP1 is that AP2 carries out after firmware upgrade terminates, and the current AP carrying out firmware upgrade has two, then continue to use the AP having carried out firmware upgrade to be that the AP not carrying out firmware upgrade carries out firmware upgrade.
8th step, AC selects an AP (AP3) in the AP not carrying out firmware upgrade, and specifies an AP (AP1) of having carried out in the AP of firmware upgrade to carry out firmware upgrade for it; And specify an AP (AP2) of having carried out in the AP of firmware upgrade to be that the AP (AP4) not carrying out firmware upgrade carries out firmware upgrade.
9th step, the IP address of AP1 and priority are informed to AP3 with the form of AC list by AC, and the IP address of AP2 and priority are informed to AP4 with the form of AC list.
Wherein, the priority of AP1 and the priority of AP2 are all set to the highest.
Tenth step, when AP3 receives the AC list of AC notice, upgrades local AC list, and is associated with on AP1 and carries out firmware upgrade; When AP4 receives the AC list of AC notice, upgrade local AC list, and be associated with on AP2 and carry out firmware upgrade.
AP1 is that AP3 carries out firmware upgrade, and AP2 is the process that AP4 carries out firmware upgrade is that AP2 carries out firmware upgrade process with AP1, describes no longer one by one here.
First carry out firmware upgrade terminate if AP1 is AP3, then AC continues to use AP1 and AP3 to be that the AP (AP5 and AP6) that not the carrying out in the first upgrading group is upgraded carries out firmware upgrade; Only have an AP not carrying out firmware upgrade if current, then in AP1 and AP3, select an AP to be that the AP not carrying out firmware upgrade carries out firmware upgrade.
First carry out firmware upgrade terminate if AP2 is AP4, then AC continues to use AP2 and AP4 to be that the AP (AP5 and AP6) that not the carrying out in the first upgrading group is upgraded carries out firmware upgrade.
AC receives the AP that firmware upgrade terminates again, as the association of AP3, then determines that AP1 is that AP3 carries out firmware upgrade and terminates.
11 step, AC specifies an AP (AP1) of having carried out in the AP of firmware upgrade to be that an AP (AP5) of not carrying out firmware upgrade carries out firmware upgrade; And specify an AP (AP3) of having carried out in the AP of firmware upgrade to be that the AP (AP6) not carrying out firmware upgrade carries out firmware upgrade.
12 step, the IP address of AP1 and priority are sent to AP5 with the form of AC list by AC, make AP5 be associated with AP1 and carry out firmware upgrade; The IP address of AP3 and priority are sent to AP6 with the form of AP list, makes AP6 be associated with AP3 and carry out firmware upgrade.
Wherein, the priority of AP1 and AP3 is all set to the superlative degree.
AP1 is that AP5 carries out firmware upgrade, and AP3 is the process that AP6 carries out firmware upgrade is the process that AP2 carries out firmware upgrade with AP1, describes no longer one by one here.
13 step, when AC determines that all AP in the first upgrading group have carried out firmware upgrade, determines whether the priority of this AC carried out amendment, if so, recovers the priority of this AC for highest.
