Detailed Description
To facilitate the description of the claimed embodiments, some concepts related to the present application will be described below.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a diagram of a connection relationship of an intelligent gateway and a server according to some embodiments. As shown in fig. 1, when an intelligent gateway is installed in a region, the intelligent gateway is directly connected to a server, an MAC address of the intelligent gateway is stored in a storage region of the server, and the server sends an upgrade file to the intelligent gateway, so that the intelligent gateway can be upgraded according to the upgrade file. When other intelligent gateways are installed in the same region, a CDN network is connected between the server and the intelligent gateways, namely the server and the CDN network are in communication connection, the CDN network is in communication connection with each intelligent gateway, and MAC addresses of all the intelligent gateways installed in the region are stored in the CDN network. Therefore, when the intelligent gateway sends an upgrading request to the server, the server transmits the configuration file to the CDN, the intelligent gateway sends the upgrading request to the CDN, and the upgrading file is downloaded in the CDN. In some embodiments, the intelligent gateway includes a router, and the upgrade control method of the intelligent gateway may be described by taking router upgrade as an example.
When The existing intelligent gateway is upgraded, The upgrading mode mainly comprises CDN upgrading and centralized control upgrading, in The OTA (Over The Air, depending on Over The Air) scheme of The conventional intelligent gateway based on CDN technology, The MAC addresses of The intelligent gateway in a packing box are continuous, and The intelligent gateways distributed to various cities are transported based on The packing box, so that The upgrading of a designated area can be completed by using a limited number of MAC address sections. Namely, the MAC address field of a region is segmented continuously, for example, the MAC address of a region is segmented, 40 intelligent gateways are taken as one segment, the MAC addresses of the 40 intelligent gateways are 1-9, 11-19, 21-29, 30-39 and the like, when the intelligent gateways in the region are upgraded, the intelligent gateways are upgraded in a segmented mode, namely, 40 intelligent gateways are upgraded, and after the upgrade is completed, the next 40 intelligent gateways are upgraded. However, the CDN upgrade method is not accurate enough in regional locking, and in an actual use scenario, the intelligent gateway is often installed disorderly due to some errors in management, and the MAC address cannot be used to control the address in the real space.
When the centralized control upgrading is adopted, the centralized control usually means that a terminal periodically initiates an upgrading request to establish a session with a server, the upgrading request comprises terminal information, the server extracts the terminal information and compares the terminal information with the information of a server database to judge whether the intelligent gateway needs upgrading or not and upgrade the version used, namely, whether the intelligent gateway needs upgrading or not and the version used for upgrading are all carried out at the server. However, the centralized control upgrading mode includes a large amount of transportation and system I/O in the server, and the upgrading packet of the upgrading mode cannot be stored by using the CDN, so that in the millions of upgrading processes, the network speed of the computing center may become a bottleneck, causing other services of the computing center to be forced to be suspended, and in order to ensure that the services of the computing center are normal, the server has to adopt a flow control algorithm, which increases the computational overhead of the server side, and reduces the real-time performance of terminal upgrading.
In order to solve the problems, the distributed algorithm is applied to an access network terminal (intelligent gateway), the area identification calculation is distributed to the cloud side without depending on a network topology structure or a centralized server, and the calculation power and the flow of the server are saved.
Fig. 2 is a connection relationship diagram of an intelligent gateway and a content distribution network provided in the embodiment of the present application. As shown in fig. 2, the intelligent gateway includes an interface and a CPU, and the intelligent gateway is in communication connection with the CDN network through the interface, and if the intelligent gateway performs upgrade, the intelligent gateway sends an upgrade request to the CDN network through the interface, and after the CDN network receives the upgrade request, the CDN network downloads the configuration file into the intelligent gateway through the interface.
The MAC version stored in the current database of the intelligent gateway and the version of the configuration file downloaded through the interface may be the same or different, and if the MAC version is the same, the MAC version in the current database is the latest version and does not need to be updated; if not, the MAC version in the current database is not the latest version, and a new version needs to be downloaded.
To facilitate identifying the version of the configuration file, the configuration file is in the format:
{
"img":
{
"product_ID":"VS002",
"hw_version":"V1.0.0",
"sw_src_ver":"V1.0.1.120",
"sw_dst_ver":"V1.1.5.138b",
"mac_limits":"B84DEE000000-B84DEEFFFFFF",
"target_URI":"http://ota.hbmtservice.com/VS007/img115138b.tar",
"target_MD5":"92332638aaa2bd84cd3a1d51f62cd716",
"cycle_time":90000
}
}
the product _ ID, the hw _ version, the sw _ src _ ver and the sw _ dst _ ver represent version information, and whether the MAC version stored in the current database of the intelligent gateway is the same as the version of the configuration file downloaded through the interface can be detected according to the version information.
In order to make the MAC version in the current database of the intelligent gateway the latest version, the configuration file downloaded by the intelligent gateway through the interface includes a URL identifying the configuration file MAC _ CFG and a version number identifying the configuration file MAC _ CFG, and the version number corresponds to the URL. That is, the configuration file is changed, a MAC _ config field is added to the configuration file, for example, the URL of the configuration file MAC _ CFG is recorded in the MAC _ config _ URL field, and a new configuration file MAC _ CFG can be downloaded from the CDN network according to the URL of the configuration file MAC _ CFG; the MAC _ config _ ver field is added to record the version number of the configuration file MAC _ CFG to confirm whether the version number is downloaded in the intelligent gateway or not through the version number.
In some embodiments, the configuration file is changed, adding the mac _ config field:
{
"img":
{
"product_ID":"VS002",
"hw_version":"V1.0.0",
"sw_src_ver":"V1.0.1.120",
"sw_dst_ver":"V1.1.5.138b",
"mac_limits":
{
"mac_config_enable":"1",
"mac_config_ver":"1235",
"mac_config_url":"http://ota.hbmtservice.com/VS007/mac_config.cfg",
}
"target_URI":"http://ota.hbmtservice.com/VS007/img115138b.tar",
"target_MD5":"92332638aaa2bd84cd3a1d51f62cd716",
"cycle_time":90000
}
}
wherein, product _ ID, hw _ version, sw _ src _ ver and sw _ dst _ ver in the configuration file represent version information of the configuration file, mac _ config _ ver represents the version number of the configuration file, and mac _ config _ URL represents the download address URL of the configuration file.
After receiving the downloaded configuration file through the interface, the intelligent gateway analyzes the configuration file to obtain the version number recorded by the configuration file, compares the version number with the current MAC version number of the intelligent gateway (the MAC version number stored in the intelligent gateway database), and judges whether the version number obtained by analysis is consistent with the current MAC version number of the intelligent gateway or not so as to confirm whether the intelligent gateway needs to be upgraded or not.
If the version number obtained by analysis is consistent with the current MAC version number of the intelligent gateway, the current MAC version number of the intelligent gateway is the latest version number, and the intelligent gateway does not need to be upgraded.
If the version number obtained by analysis is not consistent with the current MAC version number of the intelligent gateway, the server updates the version number of the intelligent gateway in the installation area, the intelligent gateway needs to be upgraded, and the MAC version number in the database of the intelligent gateway is updated according to the version number obtained by analysis.
And when the version number obtained by analysis is inconsistent with the current MAC version number of the intelligent gateway, the intelligent gateway downloads a new configuration file MAC _ CFG according to the URL of the MAC _ config _ URL identification configuration file MAC _ CFG in the configuration file so as to upgrade the intelligent gateway through the new configuration file MAC _ CFG.
After the MAC version number of the intelligent gateway is successfully matched, the address information needs to be matched, namely whether the MAC of the intelligent gateway is contained in an MAC address library in the configuration file is judged. When the MAC of the intelligent gateway is contained in the MAC address library of the configuration file, the intelligent gateway is indicated to be successfully matched with the address information.
In some embodiments, the CDN network may periodically send the configuration file to each installation area, and after the intelligent gateway receives the downloaded configuration file, the MAC address included in the configuration file received by the intelligent gateway may be an intelligent gateway MAC address library of another installation area, that is, the MAC address of the intelligent gateway and the MAC address library included in the received configuration file belong to different installation areas, so that the installation area needs to be confirmed according to the MAC address of the intelligent gateway and the MAC address library included in the configuration file.
In order to identify the installation area of the intelligent gateway, the configuration file downloaded by the intelligent gateway through the interface further comprises a config file, the config file comprises a MAC address base of the intelligent gateway in the area and an upgrade file downloading address corresponding to the MAC address, and the MAC address in the MAC address base is discontinuous. That is, a configuration file is sequentially downloaded from the CDN network, and a MAC _ config file is added to the configuration file, and MAC address libraries of all intelligent gateways in the installation area are added to the MAC _ config file, MAC addresses in the MAC address libraries are sorted by small and large, and the MAC addresses are separated by a fixed separator, such as 08674E00001234, 08674E0005678, 08674E0000ABCD, 08674E000 BCDE.
When the installation area of the intelligent gateway is identified, the intelligent gateway analyzes the downloaded configuration file to obtain a config file in the configuration file, and searches whether an MAC address matched with the MAC of the intelligent gateway exists in an MAC address library in the config file, namely, searches whether the MAC address of the intelligent gateway exists in the MAC address library in the config file, if the MAC address of the intelligent gateway exists in the MAC address library, the intelligent gateway and the intelligent gateway with each MAC address in the config file are positioned in the same installation area; if the MAC address of the intelligent gateway does not exist in the MAC address library, the intelligent gateway and the intelligent gateway of each MAC address in the config file are located in different installation areas, the upgrade is quitted at the moment, the configuration file needs to be downloaded from the CDN again, and the installation areas are identified again.
Since each MAC address in the configuration file is a character string, the field of each MAC character string is fixed, and the MAC address can be represented in a numerical manner. Each MAC character string is in a 16-system form, and each MAC character string can be converted into a numerical value through the 16-system form, namely, each MAC address in a MAC address library contained in a configuration file is converted into a MAC numerical value through the character string.
After each MAC address in the MAC address pool is converted to a MAC value, the converted MAC values are sorted by size and size, and the values corresponding to each MAC address are separated by a fixed separator, e.g., 23653818799924, 2365384518817400, etc.
And after converting each MAC address from a character string into a shaping numerical value, searching by a dichotomy by using a comparative shaping method, if a config file contains 5 MAC addresses, converting the 5 MAC addresses from the character string into the numerical values, sequencing the converted numerical values from small values to large values, and searching the sequenced numerical values by adopting the dichotomy, wherein the sequence is 1, 2, 3, 4 and 5.
If the value of the MAC of the intelligent gateway is converted into 2, firstly, the dichotomy is adopted to search for 3 from the sorted 1, 2, 3, 4 and 5, and then the dichotomy is continuously adopted to search for 2 from the 1, 2 and 3, so that the MAC address matched with the MAC of the intelligent gateway exists in the MAC address library.
When the MAC of the intelligent gateway is converted into the value of 6, the dichotomy is adopted to search for 3 from the sorted 1, 2, 3, 4 and 5, the dichotomy is continuously adopted to search for 2 from the 1, 2 and 3, and then the dichotomy is continuously adopted to search for 1 from the 1 and 2, so that the value 6 corresponding to the MAC of the intelligent gateway is not searched after the sorted value is searched by adopting the dichotomy, and the MAC address matched with the MAC of the intelligent gateway does not exist in the MAC address library.
If the MAC address matched with the MAC of the intelligent gateway is not found from the MAC address library in the config file, the matching of the MAC address is failed, the MA C of the intelligent gateway and the MAC address in the configuration file are in different installation areas, and the upgrading of the intelligent gateway is quitted.
If the MAC address matched with the MAC of the intelligent gateway is found from the MAC address library in the config file, the MAC address is successfully matched, the MAC of the intelligent gateway and the MAC address in the configuration file are in the same installation area, and the intelligent gateway is upgraded through the configuration file.
And when the MAC address is successfully matched, the CPU acquires an upgrading file downloading address IMG _ URL corresponding to the matched MAC address from the analyzed configuration file, acquires an upgrading file IMG _ TAR according to the downloading address IMG _ URL, and carries out version upgrading on the intelligent gateway through the upgrading file IMG _ TAR.
In some embodiments, when the intelligent gateway downloads the upgrade file IMG _ TAR according to the download address IMG _ URL, the configuration file MAC _ CFG may be deleted from the configuration file first because the upgrade file is large and the occupied field is large, and then the upgrade file IMG _ TAR is downloaded according to the download address IMG _ URL.
When the server uploads the intelligent gateway upgrading file to the CDN, the server calculates upgrading data of the upgrading file through an algorithm to obtain an MD5 configuration file, and then uploads the upgrading file and the MD5 configuration file to the CDN together.
In order to verify that the upgrade file IMG _ TAR downloaded by the intelligent gateway is the same as the upgrade data uploaded by the server, after the intelligent gateway downloads the upgrade file IMG _ TAR from the CDN network, the downloaded upgrade file IMG _ TAR and the MD5 configuration file are calculated through the same algorithm, namely, the MD5 configuration file of the upgrade file IMG _ TAR is verified.
If the verification of the MD5 configuration file of the upgrade file IMG _ TAR is successful, it indicates that the upgrade file IMG _ TAR downloaded by the intelligent gateway is the same as the upgrade data in the upgrade file uploaded by the server, and the intelligent gateway can upgrade the intelligent gateway according to the downloaded upgrade file IMG _ TAR.
If the MD5 configuration file of the upgrade file IMG _ TAR is not successfully verified, the fact that the upgrade data in the upgrade file IMG _ TAR downloaded by the intelligent gateway is different from the upgrade data in the upgrade file uploaded by the server is indicated, so that the intelligent gateway exits the upgrade, and the intelligent gateway downloads the configuration file from the CDN network again.
The intelligent gateway comprises an interface and a CPU (central processing unit) electrically connected with the interface, wherein the interface is used for receiving a downloaded configuration file, namely the intelligent gateway sends an upgrading request to a CDN (content delivery network) through the interface so as to download the configuration file from the CDN, and the configuration file comprises an MAC (media access control) address library of the intelligent gateway in a region and an upgrading file downloading address corresponding to an MAC address, so that the intelligent gateway receives the MAC address library containing all the MAC addresses of the intelligent gateway in an installation region so as to identify the installation region of the intelligent gateway; the MAC addresses in the MAC address library are discontinuous, and when the intelligent gateways of the installation area are upgraded, the MAC addresses of all the intelligent gateways need to be matched and identified, so that the intelligent gateways of the installation area can be upgraded simultaneously; after receiving the downloaded configuration file, the intelligent gateway searches whether an MAC address matched with the MAC of the intelligent gateway to be upgraded exists in an MAC address library, namely, whether the MAC address of the intelligent gateway to be upgraded belongs to the installation region is checked; if the matched MAC address exists in the MAC address library, the intelligent gateway to be upgraded belongs to the installation region, the upgrade file is downloaded according to the download address corresponding to the matched MAC address, and after the upgrade file is successfully verified, the intelligent gateway is upgraded according to the upgrade file. That is, the configuration file only contains the download address of the upgrade file, and the intelligent gateway downloads the upgrade file from the CDN network according to the download address without the need for the server to provide an upgrade package, which can save server effort and traffic.
The positioning algorithm does not depend on auxiliary algorithms such as protocols and sensors in a network topology angle, and accurately positions the space where the user is located. The structure is optimized, the server is miniaturized, the server side is accurately and simply calculated, the cost of components is saved, the overstaffed server overhead is simplified, the hardware cost and the maintenance cost of the server are saved, and the network flow cost of the server outlet is saved.
Based on the intelligent gateway described in the above embodiment, the embodiment of the present application further provides a region upgrade control method for an intelligent gateway, the method applies a distributed algorithm to the intelligent gateway, the positioning algorithm does not depend on auxiliary algorithms such as protocols and sensors in a network topology angle, the space where the user is located is accurately positioned, the server is miniaturized, the server side is refined and simplified in calculation, and terminal optimization is achieved.

s100: and receiving a downloaded configuration file, wherein the configuration file comprises an MAC address base of the intelligent gateway in the region and an upgrade file download address corresponding to the MAC address, and the MAC address in the MAC address base is discontinuous.
The CDN network may periodically send configuration files to each installation area, and after the intelligent gateway receives the downloaded configuration files, the MAC address base included in the configuration files received by the intelligent gateway may be an intelligent gateway MAC address of another installation area, so that the installation area needs to be confirmed according to the MAC address of the intelligent gateway and the MAC address base included in the configuration files.
In order to identify the installation area of the intelligent gateway, the configuration file downloaded by the intelligent gateway through the interface further comprises a config file, the config file comprises a MAC address base of the intelligent gateway in the area and an upgrade file downloading address corresponding to the MAC address, and the MAC address in the MAC address base is discontinuous. The method comprises the steps that configuration files are downloaded from a CDN network in order, MAC _ config files are added in the configuration files, MAC address libraries of all intelligent gateways in an installation area are added in the MAC _ config files, MAC addresses in the MAC address libraries are sorted by size and size, and the MAC addresses are separated by fixed separators.

As shown in fig. 4, when the address matching is performed between the MAC address library in the config file and the MAC of the intelligent gateway, the version number of the identifier in the configuration file needs to be obtained through parsing, and whether the parsed version number is consistent with the current MAC version number of the intelligent gateway is determined to determine whether the intelligent gateway needs to be upgraded.
