Detailed Description
In the Mesh network, different types of APs providing the Mesh service have different version upgrading processes, and taking the Mesh network structure of fig. 1 as an example, the version upgrading process of the AP providing the Mesh service is described as follows:
the version upgrading process of the MPP comprises the following steps: the MPP establishes CAPWAP connection with the AC through a wire, and finishes version upgrading through a wire link according to a standard firmware upgrading method;
the version upgrading process of the MP comprises the following steps: the MP establishes a temporary Mesh link with the MPP first, and downloads relevant configuration information from the AC; thirdly, establishing a formal Mesh link with the MPP again through negotiation, and then downloading the latest version file by establishing CAPWAP connection with the AC to finish version upgrading;
and (3) version upgrading process of MAP: MAP establishes a temporary Mesh link with MP first, and downloads relevant configuration information from AC; and then, negotiating with the MP again to establish a formal Mesh link, and then establishing CAPWAP connection with the AC to download the latest version file so as to finish version upgrading.
At present, in the process of upgrading the version of the AP providing the Mesh service in the Mesh network, each AP providing the Mesh service needs to download the latest version file through the AC, so that the AP providing the Mesh service will inevitably have a certain impact on the AC when upgrading the version; in addition, when the MP and the MAP are upgraded, the version file needs to be transmitted through the Mesh link, and particularly during the MAP upgrading process, the version file needs to be transmitted both on the Mesh link between the MP and the MPP and on the Mesh link between the MP and the MAP. When the bandwidth of one of the Mesh links is relatively low, the flow for downloading the version file may impact the Mesh link, thereby causing the situations that the downloading time of the version file is too long or the Mesh link is broken by the flow impact, and the like.
In order to solve the problems in the prior art, the invention provides a method and a device for version upgrading, which can enable an AP providing Mesh service to judge whether the source AP needs version upgrading or not through monitoring version information of a source AP of an adding request message carried by the adding request message after upgrading is finished and the acquired preset version information of the source AP; if the updating is needed, the agent AC replies an access response message to the source AP so as to enable the source AP to send a file request of the latest version; when the AP receives the latest version file request sent by the source AP, the latest version file may be sent to the source AP according to the latest version file request. Because the AP (MPP or MP) providing Mesh service can judge whether the source AP sending the joining request message needs version upgrading by the proxy AC and send the latest version file to the source AP by the proxy AC, the invention can avoid the source AP from requesting the version file from the AC and reduce the burden of the AC; and because the AP providing the Mesh service and the source AP are only separated by one hop of Mesh link, compared with the prior art that the source AP downloads the latest version file from the AC, the AP providing the Mesh service sends the latest version file to the source AP, and the impact of the flow transmitted by the version file on the Mesh link can be relieved.
Referring to fig. 2, a flowchart of a version upgrade method according to an exemplary embodiment of the present invention is applied to an AP providing a Mesh service in a Mesh network, where the AP providing the Mesh service is an MP or an MPP. The method comprises the following steps:
in this embodiment, when the AP providing the Mesh service is upgraded, the AP may serve as a proxy AC to monitor an add request packet sent to the AC by an AP downstream from the AP providing the Mesh service, where the downstream AP is a source AP of the add request packet. When the AP providing the Mesh service is specifically the MPP, the monitored source AP is the MP; when the AP providing the Mesh service is specifically an MP, the source AP monitored by the AP is a MAP.
It should be noted that, in a multi-hop Mesh networking, if a plurality of upstream APs exist in a downstream AP, and each upstream AP finishes upgrading and starts a monitoring function of the downstream AP; when the downstream AP sends the join request message, an optimal link may be selected according to bandwidth or link loss calculation to send the join request message to the AC, and the upstream AP on the optimal link may monitor the join request message of the downstream AP. Other upstream APs will not receive the join request message of the downstream AP.
When the AP providing the Mesh service monitors an addition request packet, it may determine whether the source AP needs version upgrade according to version information of a source AP of the addition request packet carried by the addition request packet and acquired predetermined version information of the source AP. Specifically, the AP providing the Mesh service may obtain predetermined version information of the source AP; then judging whether the version information of the source AP is the same as the preset version information of the source AP or not, and if not, determining that the source AP needs version upgrading; if the source AP does not need version upgrading, the joining request message of the source AP can be transmitted to the AC through the source AP, and the source AP is enabled to be on-line formally on the AC.
It should be noted that the version information of the source AP is different from the predetermined version information of the source AP, and specifically may include: the version information of the source AP is higher than the predetermined version information, and the version information of the source AP is lower than the predetermined version information.
As an embodiment, the predetermined version information of the source AP may be obtained specifically by: because the discovery message and the join request message sent by the source AP both carry the device model of the source AP, the device model of the source AP can be obtained in the discovery message of the source AP, and the device model of the source AP can also be obtained in the join request message of the source AP, but when the discovery message of the source AP is received, if the device model is determined to be not supported on the AP providing Mesh service according to the device model of the source AP in the discovery message, the message of the source AP is refused to be processed, so that the unsupported device model can be filtered, and the version upgrading efficiency is improved; in addition, the device model of the source AP carried in the join request message may also be obtained.
The AP providing the Mesh service can compare whether the own equipment model is the same as the equipment model of the source AP or not; if the version information of the AP providing the Mesh service is the same as the version information of the source AP, the version information of the AP providing the Mesh service is determined to be the preset version information of the source AP; if the difference is different, the AP which needs to provide the Mesh service further sends the device model and the version information carried in the join request message to the AC, the AC searches the latest version information corresponding to the source AP according to the received device model and version information, and returns the latest version information corresponding to the source AP, and the AP which provides the Mesh service can determine the received latest version information as the predetermined version information of the source AP.
in this embodiment, when it is determined that the source AP needs version upgrade, the AP providing the Mesh service may reply an addition response packet to the source AP by using the proxy AC, so that the source AP sends a file request of the latest version when receiving the addition response packet.
In this embodiment, the AP providing the Mesh service receives a request sent by the source AP to receive the latest version file sent by the source AP, and may send the latest version file to the source AP according to the latest version file request, so that the source AP obtains the latest version file to complete version upgrade.
As an embodiment, when receiving a file request of a latest version sent by a source AP, an AP providing a Mesh service may further check whether a file of the latest version requested by the file request of the latest version exists locally; if not, downloading the latest version file requested by the latest version file request from the AC, and sending the downloaded latest version file to the source AP; if yes, the latest version file requested by the locally-existing latest version file request is sent to the source AP.
As an embodiment, before the AP providing the Mesh service does not complete the upgrade, an add request message may be sent to the AC, and when the AP providing the Mesh service is an MP, an add response message sent by the peer MPP that has completed the upgrade may be received, a latest version file request may be sent to the peer MPP that has completed the upgrade, and the peer MPP that has completed the upgrade may be received to send a latest version file and perform the version upgrade; when the AP providing the Mesh service is the MPP, the AP may receive an add response packet sent by an AC, send a latest version file request to the AC, receive the latest version file sent by the AC, and perform version upgrade.
Compared with the prior art, the invention receives the adding request message of the source AP by the upgraded AP proxy AC providing the Mesh service, and can send the version file to help the source AP to finish the version upgrade by the proxy AC. The AP providing the Mesh service can judge whether the source AP sending the joining request message needs version upgrading or not by the proxy AC and send the latest version file to the source AP by the proxy AC, so that the source AP can be prevented from requesting the version file to the AC, and the burden of the AC is reduced; and because the AP providing the Mesh service and the source AP are only separated by one hop of Mesh link, compared with the prior art that the source AP downloads the latest version file from the AC, the impact of the transmission of the version file on the Mesh link can be relieved by sending the latest version file to the source AP by the AP providing the Mesh service.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following takes the MPP and MP upgrading process in the Mesh network as an example, and the solution of the present invention is further described in detail with reference to fig. 3.
Fig. 3 is a flowchart of a version upgrade process in the embodiment of the present invention, and in the embodiment, an MPP is taken as an example of an agent AC of an MP to assist the MP in performing the version upgrade, which specifically describes a process flow of a Mesh AP version upgrade method provided by the present invention, where the method includes:
301, MPP requests the latest version file from AC through wired connection;
the role of the proxy AC is to listen to Discovery (Discovery) messages and Join Request (Join Request) messages sent by other MPs to the AC and provide version file downloading service for the downstream MPs.
305, monitoring a Discovery message sent by the MP by the MPP, and judging whether the equipment model of the MP is the same as that of the MPP; if yes, go to step 306; if not, go to step 310;
and 307, the MPP transparently transmits the Join Request message of the MP to the AC for processing.
After the MP is upgraded, steps similar to MPP for assisting the MP to finish version upgrading can be executed, and MAP is assisted to finish version upgrading.
311, when the latest version information corresponding to the MP returned by the AC is received, judging whether the latest version information of the MP is the same as the version information of the MP, and if so, turning to 307; if not, go to step 312;
Therefore, in the invention, when the types of the APs in the whole Mesh network are the same, the AC only needs to complete the upgrading of the MPP, and the AC sets itself to be the proxy AC role after the upgrading of the MPP is completed, so that the version upgrading process of the neighbor MP is completed; after MP upgrade is completed, MPP is switched to a normal role, and MP is switched to a proxy AC role, so that MAP upgrade is completed, impact on AC and MESH links can be reduced, and version upgrade efficiency of MP and MAP is improved. If the MPP, the MP and the MAP in the Mesh network only have one AP model, only the MPP downloads the latest version file from the AC, the MPP can be used as an agent AC to help the MP to upgrade the version after upgrading the MPP, and the MPP can be used as the agent AC to help the MAP to complete upgrading after upgrading the MP, so that the MP and the MAP cannot download the latest version file from the AC. In addition, when the MP and the MAP request to download the latest version file, the flow of the downloaded version file only passes through the one-hop Mesh link, and no overlarge impact is generated on a Mesh network, so that the impact of the transmission of the version file on the AC and the Mesh link can be effectively reduced.

In summary, the present invention enables an AP providing a Mesh service to, after completing version upgrade itself, if monitoring an add request message, determine whether the source AP of the add request message needs version upgrade according to version information of the source AP carried by the add request message and acquired predetermined version information, if so, reply an add response message to the source AP to trigger the source AP to send a file request of a latest version; then receiving a latest version file request sent by the source AP, and sending a latest version file to the source AP according to the latest version file request; wherein, when the AP providing the Mesh service is the MP, the source AP is the MAP, and when the AP providing the Mesh service is the MPP, the source AP is the MP. Because the AP (MPP or MP) providing Mesh service can judge whether the source AP sending the joining request message needs version upgrading by the proxy AC and send the latest version file to the source AP by the proxy AC, the invention can avoid the source AP from requesting the version file from the AC and reduce the burden of the AC; and because the AP providing the Mesh service and the source AP are only separated by one hop of Mesh link, compared with the prior art that the source AP downloads the latest version file from the AC, the impact of the flow transmitted by the version file on the Mesh link can be relieved by sending the latest version file to the source AP by the AP providing the Mesh service.
