[0027] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. SUMMARY OF THE INVENTION

[0029] As mentioned above, the present invention provides a method and system for nearby access based on active detection, which significantly improves the stability of the service and the user experience through the method of nearby access of the client terminal to the media server.

[0030] Exemplary Methods

[0031] Figure 1 : is a flow chart of a method for nearby access based on active detection provided by an embodiment of the present invention, and the embodiment includes the following steps:

[0032] S101: The detection server obtains the company information and geographic location information of the client terminal that logs into the system server.

[0033] The detection server is used to detect the optimal media server accessed by the client terminal and the optimal route when accessing the optimal media server;

[0034] The site code information is used to mark the optimal media server accessed by the client terminal and the optimal line when accessing the optimal media server. The site code information consists of four fields: enterprise code, country code, regional code and enterprise computer room identification. The enterprise code, country code and regional code are used to determine the optimal media server connected to the client terminal, and the enterprise computer room identification is used to determine the optimal line used when the client terminal is connected to the optimal media server. Specifically, the enterprise code, the public cloud defaults to EDEF, and when a hybrid cloud enterprise registers, a fixed enterprise code will be assigned; the country code, the default country code 86 of China is used. If it is deployed in other countries, it is selected according to the standard country code definition; the regional code, the default domestic computer room area code, and the default foreign SLDEF; the enterprise computer room identification is used to distinguish different computer rooms. The client terminal and the media server in the same computer room can communicate with each other through the intranet, and the client terminal and the media server in different computer rooms cannot communicate with each other through the intranet, but can only communicate with each other through the external network.

[0035] The media server is used to provide media content access services for client terminals. For example, the client terminals can play audio and video and download content through the media server.

[0036] Specifically, the step of the detection server acquiring the enterprise information and geographic location information of the client terminal that logs into the system server includes:

[0037] First, the client terminal logs in to the system server through the system server's URL and its own account and password. After successful login, the client terminal will upload the company information and IP address of the device to the system server's database. The system server's database stores the company information and IP address of the client terminal.

[0038] Preferably, when the IP address of the client terminal is only an intranet address or an extranet address, the IP address of the client terminal is uploaded to the database of the system server; when the IP address of the client terminal has both an intranet address and an extranet address, the extranet address is intercepted by using a reverse proxy server, and only the intranet address of the client terminal is uploaded to the database of the system server.

[0039] After the client terminal uploads the enterprise information and IP address to the database of the system server, the detection server obtains the IP address information of the client terminal through the system server and queries the specific geographic location information of the client terminal based on the IP address information of the client terminal, so as to allocate the nearest media server to the client terminal according to the specific geographic location.

[0040] In the above steps, in addition to obtaining the specific geographical location information of the client terminal through the IP address, the detection server can also improve the accuracy and precision of obtaining the geographical location through the application of technologies such as GPS and WI-FI positioning.

[0041] S102: The detection server determines the first three fields of the site code information of the client terminal through the enterprise information and geographic location information of the client terminal.

[0042] Specifically, the detection server determines the enterprise code in the site code information of the client terminal through the enterprise information to which the client terminal belongs. For example, after detection, the detection server determines that the enterprise to which the client terminal belongs is an enterprise using a hybrid cloud, and the enterprise code assigned to the client terminal A is E000001. The detection server determines the country code and the area code in the site code information of the client terminal through the geographical location information of the client terminal. For example, after detection, the detection server determines that the geographical location of the client terminal is Beijing, and the country code assigned to the client terminal is 86 and the area code is 010.

[0043] In addition, the detection server may also customize the country code and area code in the site code information of the client terminal.

[0044] For example, when the detection server detects that the load of the media server in the Guangzhou area is relatively low and the load of the media server in the Beijing area is too high, the area code of the client terminal A in Beijing can be customized to 020 (the area code of Guangzhou). In this way, the client terminal A in Beijing can access the media server in Guangzhou with a relatively low load, thereby improving the user experience of the client terminal A in accessing the media server and reducing the load pressure on the media server.

[0045] In addition, when the detection server fails to query the geographic location information of the client terminal, it determines the country code and area code in the site code information of the client terminal according to the default geographic location information, and allocates a specific media server for the client terminal using the default geographic location to access.

[0046] S103: The detection server allocates an optimal media server to the client terminal according to the first three fields of the site code information.

[0047] Specifically, the detection server allocates the nearest media server to the client terminal according to the first three fields of the site code information of the client terminal.

[0048] For example, after detection, the detection server determines that the first three fields of the site code information of client terminal A are E000001-86-010. The detection server then assigns the client terminal A a media server in Beijing of its company based on the first three digits of the site code information of the client terminal, and returns the detection address of the media server to the client terminal A so that the client terminal can access the media server based on the detection address.

[0049] S104: The client terminal performs network detection on the optimal media server.

[0050] like Figure 2 As shown, step S104 specifically includes:

[0051] S201: The client terminal accesses the optimal media server through the detection address of the media server.

[0052] Specifically, the client terminal accesses the optimal media server screened out by the detection server through the address of the media server. If the client terminal can access the media server through the intranet, the media server is accessed through the intranet first. If the media server cannot be accessed through the intranet, the media server is accessed through the extranet.

[0053] S202: The client terminal records network status information when accessing the media server.

[0054] Specifically, after the client terminal accesses the media server screened by the detection server, the network status information when accessing the media server will be recorded, so that the detection server can select the best access line for the client terminal based on the network status information, thereby improving the efficiency of the client terminal in accessing the media server and improving the user experience and satisfaction.

[0055] S105: The detection server determines the best route for the client terminal to access the optimal media server according to the network detection result.

[0056] Specifically, the client terminal returns the network status information to the detection server, and the detection server determines whether the client terminal accesses the optimal media server through an intranet or an extranet according to the network status information.

[0057] In addition, when the detection server determines that the client terminal accesses the optimal media server through the intranet, the detection server assigns the client terminal an enterprise computer room identifier that is the same as that of the optimal media server. For example, when client terminal A accesses media server B, after detection, it is determined that client terminal A can access the media server through the intranet, then the client terminal A is assigned an enterprise computer room identifier that is the same as that of the media server B; when the detection server determines that the client terminal accesses the optimal media server through the extranet, the detection server assigns the client terminal an enterprise computer room identifier that is different from that of the optimal media server. For example, when client terminal A accesses media server B, after detection, it is determined that client terminal A can only access the media server through the extranet, then the client terminal A is assigned an enterprise computer room identifier that is different from that of the media server B.

[0058] After two detections, the detection server finally determines the four fields of the site code information of the client terminal. When the client terminal applies for access to the media server again, if the IP address of the client terminal has not changed, the detection server directly allocates the optimal media server and the optimal access line to the client terminal based on the site code information of the client terminal, without the need to re-detect the optimal media server and the optimal line that the client terminal can access. This can save the time for the client terminal to access the optimal media server and improve the customer's user experience; if the IP address of the client terminal changes, the detection server needs to re-detect to determine the site code information of the client terminal, and then re-allocate the optimal media server and the optimal access line that the client terminal can access based on the new site code information of the client terminal.

[0059] In the second embodiment, the detection server can also monitor the load balancing status of the media server in real time, and dynamically adjust which media servers the client terminal can access according to the load balancing mechanism. When the detection server detects that the current media server is overloaded, the number of client terminals accessing the media server will be reduced accordingly, and vice versa, the number of client terminals accessing the media server will be increased accordingly. In addition, the detection server can also count the number of client terminals in each area, and determine the number of media servers deployed in the area according to the number of client terminals in different areas, so that the media server resources can be used most fully and the waste of resources can be reduced.

[0060] In a third embodiment, the detection server can predict the best route for the client terminal to access the optimal media server based on historical detection data and current detection results, which can further improve the accuracy of the detection results.

[0061] S105: The client terminal accesses the optimal media server through the optimal line. After the detection server allocates the optimal media server and the optimal access route to the client terminal, the client terminal can access the resources of the media server through the optimal access route.

[0062] Figure 3 : This is an interaction diagram provided by an embodiment of the present invention. First, client terminal A logs in to the system server, and then the detection server obtains the enterprise information and IP address of the client terminal A (step 1). Then, the first three fields of the site code information of the client terminal A are determined based on the above information, and the optimal media server is allocated to the client terminal A based on the first three fields of the site code information, and the detection address of the media server is returned to the client terminal A (step 2). The client terminal A is connected to the media server, and then it is determined whether the client terminal A and the media server can be connected through the intranet (step 3) and the determination result is returned to the detection server (step 4). The detection server determines whether the client terminal A is connected to the optimal media server through the external network or the intranet based on the result, and determines the fourth bit of the site code information of the client terminal A, that is, the enterprise computer room identifier (step 5). Afterwards, when the client terminal A requests to access the media server again, the detection server can directly allocate the optimal media server to the client terminal A based on the site code information of the client terminal and the site code information of the media server, and determine the best access route, including deciding whether to use the intranet or the public network for access (step 6).

[0063] Figure 4 This is a timing diagram provided by an embodiment of the present invention. The client terminal logs in to the system server (step 1), the system server records the enterprise information and IP address of the client terminal in the database, and then the detection server obtains the enterprise information and IP address of the client terminal (step 2), and the detection server queries the geographic location information of the client terminal through the IP address (step 3). After the above steps are completed, the detection server returns the detection address to the client terminal (step 4), the client terminal detects the media server according to the detection address (step 5), and returns the detection result to the detection server (step 6), the detection server determines the site code information of the client terminal according to the detection result and records it in the database of the system server (step 7), and then the client terminal can transmit data with the media server (step 8).
