Description
Technical field
The present invention relates to the thin AP upgrade technical field, particularly the method for AP rapid batch upgrading in a kind of thin AP architecture wlan network.
Background technology
Traditional wlan network mainly is to set up for enterprise or household internal mobile subscriber's access.Only based on this demand, often need minority AP just can satisfy.Usually we call fat AP to the AP of setting up in view of the situation.The design feature of fat AP be with the physical layer of WLAN, ciphering user data, user authenticate, the function of QoS, network management, roaming technology and other application layers rolls into one, so its complete function but complex structure.Along with the development of wireless network, need the place of a large amount of AP of deployment more and more, the drawback of fat AP is also more and more obvious.Therefore, new trend has appearred in WLAN under application developments such as enterprise, and the framework of thin (FIT) AP+AC arises at the historic moment.
Wireless controller AC is responsible for access control, forwarding and the statistics of network in the thin AP+AC framework, the configuration monitoring of AP, roaming management, the OAMAgent of AP and security control etc., the functions such as statistics that encryption and decryption, radio physical layer PHY function, the RF of responsible 802.11 messages of thin AP eats dishes without rice or wine.The advantage of thin AP+AC framework networking mode has: download the suitable device configuration information from AC automatically when 1) thin AP starts, need not to be configured manually when configuration information change or renewal.2) thin AP can obtain the IP address automatically, the AC that automatic discovery can insert, and insensitive to the network topology between AC and the thin AP.3) AC supports Configuration Agent and the inquiry proxy of thin AP, the user can be communicated to the thin AP equipment of appointment smoothly to the configuration of thin AP, state and the statistical information that can check thin AP simultaneously.4) AC supports to issue latest edition software to thin AP, the thin AP of auto-update.Under the situation of large-scale network-estabilishing application deployment, thin AP+AC framework has convenient centralized management, three layers of roaming, issues advantage such as authority based on the user than fat AP framework, and therefore, thin AP+AC is more suitable for the WLAN development trend.
Under thin AP+AC framework, wireless access point AP can not work independently, and need be used with wireless controller AC, so it is interconnected to need have supporting communication protocol can allow them carry out between AP and AC.The earliest, Cisco has formulated tunnel communication agreement---the LWAPP between the first AP-AC, and then, IETF set up CAPWAP working group with the tunnel protocol between standardized A P and AC in order to solve the incompatibility problem of tunnel protocol between each vendor A P-AC in 2005.
Existing C APWAP upgrading scheme can occur in two stages, first be the CAPWAP state machine in the Image Data stage, second is that manual mode allows AP upgrade to new version after the CAPWAP state machine RUN.But they are the same the upgrading stage alternately:
1, AP sends Image Data Request message according to the image file information that gets access to AC, wherein carries Image Identifier element and Initiate Download element, and is identical in the former value and the Join Response message.If Join Response message does not carry Image Identifier element, after directly sending Configure State Request message, AP enters the Configure process, and just escalation process is controlled by AC.
2, AC is after receiving Image Data Request message, filename according to appointment in the Image Identifier element wherein, affix path prefix (each manufacturer freely realizes), find this document, and response Image Data Response message, wherein carry Image Information element, size field in this element is the length of image file, and the hash field value be 0(here the hash field be that 0 main cause is to consider efficiency, it is whole that to read version file speed slower, efficient is lower when a plurality of files are downloaded concurrent carrying out, and therefore optimizes, and in the end carries HASH in a slice).If do not find corresponding image file, then respond failed download, and finish downloading process.
3, AC initiatively sends Image Data Request message to AP, wherein carries Image Data element, and the data field of this element is filled in the data of image file.The length of the image file data that each message carries is 1024 bytes, except last a slice, and can be less than 1024 bytes.AP receives Image Data Request message at every turn, preserves the image file data, and responds Image Data Response message to AC, confirms to receive successfully.Repeatedly message interaction by between AC and the AP sends to AP with the image file data gradually, sends last Image Data Request message to AP until AC.
When 4, AC transmits last Image Data Request message to AP, should carry Image Information element again, the size field in this element is the length of image file, and the hash field value is the hash value of whole image file.The Data the type field of Image Data element is set to the EOF type in the Image Data Request message.
5, when AP receives the Image Data Request message that has EOF sign, just think that AC has sent to finish.AP reconsolidates all image file data that receive and is image file, and according to size field and hash field in the Image Information element that carries in last Image Data Request message, check whether the image file that receives is legal.If legal, then respond the Response message, show correctly to receive; Otherwise respond the Response message, show corresponding type of error.
From practical application, hundreds of even thousands of s' AP in common load of wireless controller.As mentioned above, if at synchronization many AP are carried out batch upgrade, bigger to the load of wireless controller, the situation that packet loss or message can't in time be handled appears easily, therefore, in order to improve the efficient of upgrading, be necessary to the improvement of the batch upgrade of thin AP.
Summary of the invention
The object of the present invention is to provide the method for the upgrading of AP rapid batch in a kind of thin AP architecture wlan network, this method can not by external resource, do not influence under the situation of original protocol-compliant, improve AP upgrading efficient, reduce AC performance pressure.

Embodiment
The invention provides the method for AP rapid batch upgrading in a kind of thin AP architecture wlan network, when many wireless access point AP send upgrade request to access controller AC, access controller AC is a upgrading group with n platform wireless access point AP, the value of n is not more than the sum of wireless access point AP, upgrade data is divided into n block data and is distributed to each wireless access point AP in the group, each wireless access point AP is transmitted this wireless access point AP block data and is collected other wireless access point AP block data to interior other wireless access point AP of group respectively, and the realignment escalation data are finished upgrading.
This method further may further comprise the steps:
(1) many wireless access point AP send the upgrade request message to access controller AC, and described upgrade request message carries downloading mode information, has namely defined the self-defined message field of a downloading mode, to select the upgrading mode.
(2) access controller AC sends response message and starts timer to wireless access point AP after receiving article one upgrade request message, waits for the upgrade request message of other n-1 platform wireless access point AP.
(3) behind the upgrade request message of the neat n platform of access controller AC collection wireless access point AP, described n platform wireless access point AP is made as a upgrading group, and upgrade data is divided into n block data, send the upgrade data message respectively to the interior n platform wireless access point AP of group then, described upgrade data message carries block data, the IP information of other n-1 platform wireless access point AP in residing index information of this wireless access point AP block data and the group, two self-defined message fields have namely been defined, one is residing index of this wireless access point AP block data, and another is the IP of other n-1 platform wireless access point AP in the upgrading group.
If the stand-by period is above behind the described timer setting-up time, access controller AC only collects the upgrade request message of neat m platform wireless access point AP, m＜n, and fail to collect the upgrade request message of neat n platform wireless access point AP, then be judged as wait timeout, access controller AC is made as a upgrading group with the m platform wireless access point AP of receiving the upgrade request message, and be not that unit arranges the upgrading group with n, and upgrade data is divided into m block data, send the upgrade data message respectively to described m platform AP then.The value of n, timer setting-up time can arrange at access controller AC.
(4) after each wireless access point AP was received the upgrade data message, the IP information according to other n-1 platform wireless access point AP in the group was transmitted to other n-1 platform wireless access point AP in the group with this wireless access point AP block data.
(5) each wireless access point AP collects n block data and after other n-1 platform wireless access point AP transmitted this wireless access point AP block data in the group, piece index information realignment escalation data according to each block data are finished upgrading, send the successful message of upgrading to access controller AC.
The present invention is described in further detail below in conjunction with accompanying drawing.
In network topology shown in Figure 1, suppose that the x value is 1000, if these 1000 AP upgrade to the AC request simultaneously, AC sends response messages for simultaneously this 1000 AP, will bring great performance pressure to AC, and be difficult to guarantee that the request of all AP can meet with a response.
Therefore, the present invention adopts method shown in Figure 2, AC waits for the upgrade request that collects n AP, AP is set as a upgrading group with this n platform, then image file is divided into n piece, send to the interior AP1 of group respectively to APn, and simultaneously AP is handed down in the IP address of other AP in the group, make between the AP and can transmit the image file block data mutually.Every AP finally can form image file to the image file block data that other AP in AC and group sends, and finishes upgrading.It is a upgrading group that Fig. 3 has represented with 10 AP, the upgrading sequential of an AP wherein, therefrom the upgrading flow process of every AP as can be seen.
Here suppose that every AP script updating time is 1 minute, and 100 AP are performance boundaries of AC, the CPU usage that just refers to AC reaches the peak, under perfect condition, also can finish in the time upgrading that is close to 1 minute, can't in time obtain handling above the message after this quantity, updating speed is certain to be affected greatly, simultaneously because the socket buffering area is limited, the packet loss phenomenon may take place, and total update time was certain to above 10 minutes.After adopting the inventive method, suppose that n is that 10(is because the handling property of AP is limited, the n value is not to be the bigger the better, suppose 10 in the performance allowed band of AP), so in fact, the quantities of messages that receives for AC and handle 100 AP of upgrading that mediate a settlement are similar, because for 10 AP, the data volume that AC handles is equivalent to 1 original AP, for AP, upgrading mode originally can't have been given play to the performance boundary of AP certainly, the present invention can take full advantage of the performance of AP, if the n value that arranges is in the scope that its performance can be born, so for the forwarding between AP, consumed time also is few, comparing at AC and wait for that answer and packet loss retransmit consumed time, is inappreciable.
The self-defined message format that the present invention is used describes in conjunction with Fig. 3 below.
Step 1, AP in enormous quantities sends upgrade request message Image Data Request to AC, on original message format basis, adds the self-defined message field of downloading mode Download Mode, to select the upgrading mode, be to represent to use upgrading mode of the present invention at 1 o'clock.
Step 2, AC replys response message Image Data Response after receiving article one message, and the information that this message comprises is consistent with original message format, and starts timer, waits for other n-1 upgrade request message.
Step 3, after AC collects n upgrade request message Image Data Request, AC is made as a upgrading group with this n AP, and image file (being upgrade data) is divided into n piece, the upgrade data message that sends is except carrying the image file block data, also can carry two self-defined message fields, one is residing index information of this AP image file block data, and another is the IP information (only just carrying to first upgrade data message that AP sends at AC) of other n-1 platform AP in the upgrading group.
Here have two problems to describe:
1, in the upgrading flow process of standard, AC carries upgrade data by upgrade request message Image Data Request, the upgrade request message Image Data Request that has carried block data that the upgrade data message here just refers to, just for step 1 in upgrade request message Image Data Request differentiate, so that understand, and this definition of special do.In like manner, in step 5, the successful message of upgrading is corresponding in the upgrading flow process of standard to be exactly response message Image Data Response.
2, block data is bigger, and AC must could send to an AP to block data by many upgrade data messages that carry data.Carrying 1k data, block data with a message, the 10M size is arranged is example, and AC can send 10,000 Image Data Request to an AP, and receives 10,000 from the Image Data Response of AP.And only just carry two above-mentioned self-defined message fields at AC to first upgrade data message that AP sends.
Step 4 after AP receives message, is extracted the IP information of other n-1 platform AP, and untouched E-Packeting.IP quantity according to the AP that extracts, can draw the value of n, the HASH table that to create a size be n is deposited the image file block data of receiving on the HASH ID chained list of response according to the piece index of receiving message, adds up the current image file block data size of receiving simultaneously.
Step 5, after collecting all image file block datas, AP reorganization image file is finished upgrading, sends the successful message of upgrading to AC and represents to upgrade successfully.
From as can be seen above-mentioned, the present invention does not change former protocols having, has just increased some self-defined message fields newly, that is to say and does not support that AP of the present invention also can be compatible.But AC and AP will develop at the present invention, to support the self-defined message field.If that initiate upgrade request is the AP that supports the self-defined message field, then can upgrade by batch upgrading method of the present invention, and also be compatible for the AP that does not support this self-defined message field, can use original C APWAP upgrading mode to upgrade.
More than be preferred embodiment of the present invention, all changes of doing according to technical solution of the present invention when the function that produces does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
