The data processing method provided by the embodiment of the invention is applied to the video network, and is used for solving the problem that the downloading rate of the client cannot be displayed when the client downloads resources from the network of the video network.
For convenience of description of the subsequent embodiments, the view network is briefly described. The video network is a centralized control network structure, and the network can be a tree network, a star network, a ring network and the like, but on the basis of the centralized control node, the whole network is controlled by the centralized control node in the network. The video network is divided into an access network and a metropolitan area network. The access network comprises a node server, an access switch and a terminal (comprising various set top boxes, coding boards, memories and the like), and the metropolitan area network comprises a metropolitan area server, a node server and a node switch; referring to fig. 1, fig. 1 shows a schematic diagram of a network topology of an internet of view according to the present invention, wherein a metropolitan area server may be deployed in different provinces, autonomous areas, etc., and a node server may be deployed in different cities and different areas of each province; the metropolitan area server can be directly connected with the node server, and can also be connected with the node server through the node switch.
The video network is connected with the existing Ethernet through an Ethernet protocol conversion gateway, the function of the Ethernet protocol conversion gateway is similar to that of a switch, namely, video network data is converted and sent to the Ethernet, so that the video network data is transmitted through the Ethernet; and converting the Ethernet data and sending the Ethernet data to the video network, so that the Ethernet data is transmitted through the video network. Specifically, when the ethernet protocol conversion gateway receives a data packet or a protocol packet sent from the internet of things, a Media Access Control (MAC) address of the ethernet protocol conversion gateway and a MAC address of a target terminal are added to the data packet or the protocol packet, and then the data packet or the protocol packet is sent to the ethernet network, and an ethernet protocol is adopted in the ethernet network for transmission; when the Ethernet protocol conversion gateway receives a data packet or a protocol packet sent by the Ethernet, the MAC address of the Ethernet protocol conversion gateway and the MAC address of the source terminal in the data packet or the protocol packet are removed, and then the data packet or the protocol packet is sent to the video network, and the video network protocol is adopted for transmission in the video network.
Referring to fig. 2, a flowchart illustrating steps of an embodiment of a data processing method of the present invention specifically includes:
step 201, after receiving a download request sent by a client, a server acquires a download rate preset by the client.
In the embodiment of the invention, the download rate of downloading data from the video network by the client can be limited by setting the client in advance, for example, the client can enter a management page for setting; wherein, the client is the above terminal, including: various set-top boxes, code boards, memories, etc., the data including various types of data such as video data, audio data, text data, picture data, etc., and the download rate may be set as desired, such as 1M/s. In the embodiment of the present invention, a uniform download rate may be set for each application program in the client, and a download rate may also be set for each different application program in the client, which is not limited herein. Referring to fig. 3, fig. 3 is a block diagram illustrating a system structure of data interaction between a client and a server in a video network, according to the present invention, when the client needs to download data, a download request may be sent to the server, which may include the above-mentioned metropolitan area server and node server; after receiving a download request sent by a client, the server can acquire a download rate preset by the client according to the download request.
Before responding to the downloading request of the client, the server of the embodiment of the invention can calculate the reading rate and the writing rate of the server by converting the downloading rate according to the acquired downloading rate. The reading rate refers to the rate of reading bytes from a database by a server, and the writing rate refers to the rate of sending bytes to a client by the server; the unit of the read rate and the write rate is KB/s, which represents a number of K bytes per second, 1K 1024 bytes.
And 203, reading the data corresponding to the downloading request from the database according to the reading rate.
And step 204, returning the read data to the client according to the write rate.
After calculating the reading rate and the writing rate of the downloading request, the server can respond to the downloading request, namely, the server reads the data corresponding to the downloading request from the database according to the reading rate; and then returning the read data to the client according to the writing rate. In the embodiment of the invention, the server can simultaneously carry out read-write operation, such as reading one byte and sending one byte to the client; or, after the read operation is performed, the write operation may be performed, for example, first 100 bytes are read, and then the 100 bytes are returned to the client.
After receiving a download request sent by a client, a server of the embodiment of the invention acquires a download rate preset by the client, and further sets the read rate and write rate of the server according to the download rate preset by the client; then reading the data requested by the client according to the reading rate, and returning the data to the client according to the writing rate; therefore, the embodiment of the invention can limit the rate of downloading resources from the video network by the client and reduce the bandwidth occupied by the client for downloading data by the client in a mode of presetting the downloading rate at the client and then adjusting the reading and writing rate of the server according to the preset downloading rate.
In another embodiment of the invention, the maximum limit number of the parallel downloading tasks can be set in the client, and further, the bandwidth occupied by the client when downloading data from the video network is further saved by limiting the maximum limit number of the parallel downloading tasks of the client.
Referring to fig. 4, a flowchart illustrating steps of another embodiment of a data processing method according to the present invention is shown, which may specifically include the following steps:
In this embodiment of the present invention, the download request may include: source information and requested data information, wherein the source information may include an ID of an application program that transmitted the download request and an IP address of a client that transmitted the download request. Therefore, after receiving a download request sent by a client, a server obtains an IP address corresponding to the client and an ID of an application program corresponding to the download request from the download request, and further obtains a preset download rate according to the IP address and the ID, which is specifically as follows:
The embodiment of the invention can also preset the maximum limit number of the parallel downloading tasks of the client so as to further save the bandwidth occupied by the client when downloading the data from the video network. The maximum limit number may be uniformly set for all application programs in the client, for example, if the system sets the maximum limit number to 5, the maximum limit number of the browser a is 5, and the maximum limit number of the browser B is also 5; the maximum limit number may be set for each application in the client, for example, the maximum limit number is set to 5 for the a browser, and the maximum limit number is set to 3 for the B browser.
In the embodiment of the invention, after the server returns data to any download request, the number of the downloading tasks of the application program corresponding to the download request can be added by 1 in the server; after the data corresponding to any download request is downloaded, subtracting 1 from the number of the downloading tasks of the application program corresponding to the download request; and after acquiring the ID of the application program, the server can inquire the number of the tasks being downloaded by the corresponding application program according to the ID. Determining the maximum limit number of the preset parallel downloading tasks according to the IP address, wherein the maximum limit number of each application program is set in different modes, so that the modes for acquiring the maximum limit number are different according to different setting modes; specifically, if the maximum limit number of each application program is uniformly set, the server can obtain the maximum limit number according to the IP address; if the maximum limit number of each application program is set respectively, the server can acquire the maximum limit number of the application program corresponding to the ID according to the IP address and the ID.
And 403, judging whether the number is smaller than the maximum limit number.
After obtaining the number of the tasks being downloaded by the application program and the maximum limit number, the server may compare the number with the maximum limit number, determine whether the number is smaller than the maximum limit number, if the number is smaller than the maximum limit number, execute step 404, and if the number is equal to the maximum limit number, execute step 405.
Of course, the above steps 402-403 may also be completed by the client, that is, each time an application program of the client downloads a task, a cookie is recorded, and then the client may determine the number of the downloading tasks according to the number of the recorded cookies; but the cookie in the client is easy to be tampered, so that when the number of the downloading services is tampered, the number of parallel downloading tasks cannot be limited, and the bandwidth occupied by the downloading request cannot be limited; therefore, the server completes the steps 402 to 403, and the security can be improved.
If the number of the tasks currently downloaded by the application program is smaller than the maximum limit number, the preset downloading rate can be obtained. In the embodiment of the invention, the download rate of each application program can be set uniformly or respectively; therefore, the manner of acquiring the download rate is different for different setting manners; if the downloading rate of each application program is uniformly set, the server acquires the downloading rate corresponding to the IP address; and if the downloading rate of each application program is set respectively, the server acquires the downloading rate corresponding to the application program corresponding to the ID according to the IP address and the ID.
And step 405, returning prompt information of download failure to the client.
If the number of the current downloading tasks of the application program is determined to exceed the maximum limit number, in order to limit the number of the parallel downloading services of the client, the server does not respond to the downloading request, namely, does not return data aiming at the downloading request; optionally, the server may return a prompt to the client that the download failed.
In the embodiment of the present invention, after the server obtains the preset download rate, the read rate and the write rate of the server can be calculated according to the download rate, which is specifically as follows:
and step 406, calculating the reading rate of the server according to the downloading rate and the preset relation.
The server can calculate the reading rate of the server according to the acquired downloading rate and a preset relation, wherein the preset relation is a conversion relation between the downloading rate and the reading rate, and the conversion relation is as follows: and 1M/s is 128 KB/s. In the embodiment of the present invention, the rules for calculating the read rate and the write rate according to the download rate include multiple rules, for example, the read rate and the write rate may be calculated according to the value of the complete download rate, or the read rate and the write rate may be calculated according to the value of the download rate in a certain proportion, and may be set according to the requirement for the bandwidth of the server. Because the reading rate and the writing rate of the server are carried out simultaneously, if the reading rate and the writing rate are calculated according to the value of the complete downloading rate, compared with the server, the bandwidth corresponding to the downloading request returned by the server is twice of the downloading rate; therefore, in order to save the bandwidth occupied by the server, the read rate and the write rate can be calculated according to the value of a certain proportion of the download rate. Optionally, a half of the value corresponding to the download rate may be adopted to calculate the read rate, and the value of the read rate is assigned to the write rate, that is, the read rate and the write rate of the server are equal; for example, if the download rate is 1M/s, 0.5M/s may be adopted to calculate the read rate, that is, the calculated read rate is 64KB/s, and the write rate is also 64 KB/s; and the actual download rate is also 0.5M/s relative to the client.
And step 408, searching the storage position of the data corresponding to the downloading request in the database.
And 409, reading the data from the database according to the reading rate according to the storage position.
After the server calculates the reading rate and the writing rate, the server can acquire the data information corresponding to the request from the downloading request, and further determine the position of the data corresponding to the downloading request, which is stored in the database, according to the requested data information; and then reading the data from the database according to the storage position and the reading rate.
And step 410, returning the read data to the client according to the write rate.
And after reading one or more bytes, the server returns the read data to the client according to the determined IP address and the write rate.
According to the embodiment of the invention, the reading rate of the server is calculated according to the downloading rate and the preset relation, and the value of the reading rate is assigned to the writing rate of the server, so that the bandwidth occupied by the server is saved; in addition, the maximum limit number of the parallel downloading tasks of the client can be set, when the number of the downloading tasks is determined to be smaller than the maximum limit number, the server obtains the preset downloading rate of the client, and then returns the corresponding number to the client, so that the bandwidth occupied by the client when downloading data from the video network is further saved; and the maximum limit number of the clients and the number of the tasks being downloaded are obtained, so that the data security is improved, and the number of the parallel downloading tasks of the clients is ensured.
