It should also be understood that the term "and/or" as used herein is meant to encompass any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present application to describe various information, the information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. Depending on the context, moreover, the word "if" as used may be interpreted as "at … …" or "when … …" or "in response to a determination".
For example, referring to fig. 1, for a structural schematic diagram of the cloud desktop system provided in the embodiment of the present application, each client (e.g., client 1, client 2) in a branch office accesses a gateway on a data center side through the internet, and each client establishes a communication connection (e.g., VDI virtual desktop infrastructure connection) with a cloud desktop virtual machine on a cloud desktop server through the gateway. The gateway is used for transmitting various data between each client and the corresponding cloud desktop virtual machine. How to implement transmission of different priorities for different types of data of different types of clients is a technical problem to be solved by the present application.
Exemplarily, referring to fig. 2, a detailed flowchart of a data transmission method provided in an embodiment of the present application is shown, where the method is applied to a gateway in a cloud desktop system, and a client communicates with a virtual machine through the gateway, and the method includes the following steps:
step 200: receiving a connection establishment request sent by a target client, wherein the connection establishment request carries the client priority of the target client.
Specifically, when a VDI connection is established between a client and a virtual machine in a cloud desktop server, a connection establishment request is sent to the cloud desktop server through a gateway.
Step 210: and recording the client priority of the target client, and forwarding the connection establishment request to a corresponding target virtual machine so as to establish connection between the target client and the target virtual machine.
Specifically, when receiving a connection establishment request sent by a target client, the gateway analyzes the connection establishment request to obtain the client priority of the target client carried by the connection establishment request, maintains the client priority locally, further forwards the connection establishment request to a corresponding target virtual machine of the target client on the cloud desktop server, and establishes connection with the target client based on the connection establishment request.
Step 220: and receiving the data to be transmitted sent by the target client, determining the channel priority of a target channel required for transmitting the data to be transmitted, and transmitting the data to be transmitted based on the client priority of the target client and the channel priority of the target channel.
In the embodiment of the present application, a preferred implementation manner is that the gateway locally presets channel priorities of various channels; then, when determining the priority of the channel required for transmitting the data to be transmitted, a preferred mode is to determine the data type of the data to be transmitted, and determine a target channel for transmitting the data to be transmitted based on the data type of the data to be transmitted; and determining the priority information of the target channel based on the priority information of various locally preset channels.
It should be noted that the VDI protocol is composed of a plurality of channels, and each channel is a TCP connection. Each channel is used for transmitting different types of data, and in the embodiment of the application, the channels at least comprise a channel for transmitting video image data, a channel for transmitting audio data, a channel for transmitting mouse and keyboard operation instructions and a channel for transmitting printing data.
That is to say, when receiving data to be transmitted sent by a target client, a gateway first determines the data type of the data to be transmitted, that is, determines which type of channel the data to be transmitted needs to adopt for transmission, and if so, determines that the data needs to adopt the target channel for transmission; then, the gateway locally maintains the channel priority of various channels, so that the channel priority of the target channel can be determined; and finally, transmitting the data to be transmitted according to the client priority of the target client and the channel priority of the target channel.
In this embodiment of the application, when the data to be transmitted is transmitted based on the client priority of the target client and the channel priority of the target channel, a preferred implementation manner is that a comprehensive priority is determined based on the client priority of the target client and the channel priority of the target channel, and the local forwarding module is scheduled based on the comprehensive priority to transmit the data to be transmitted, where the higher the comprehensive priority is, the more times the forwarding module can be scheduled are, the lower the comprehensive priority is, and the fewer times the forwarding module can be scheduled is.
In practical application, after the gateway receives the data to be transmitted sent by the client, the local scheduler of the gateway schedules the local forwarding module to process the data to be transmitted, that is, the priority of data processing can refer to the priority of scheduling the forwarding module to perform data transmission, that is, the priority of the forwarding module is used. Data with high client priority and channel priority can preferentially use the forwarding module.
In an embodiment of the present application, a preferred implementation manner is that the client priority is a client privilege value, and the channel priority is a channel privilege value, where the higher the privilege value is, the higher the mark priority is.
For example, the client specific value is 1-9 levels, the channel specific value is also 1-9 levels, and when the privilege value is higher, it indicates that the priority is higher, that is, the processing priority of the data corresponding to the channel specific value of 9 sent by the client with the specific value of 9 is the highest. Similarly, the processing priority of the data with the channel specific value of 1 sent by the client with the specific value of 1 is the lowest.
Then, when determining the comprehensive priority based on the client priority of the target client and the channel priority of the target channel, a preferred implementation manner is to calculate the comprehensive priority based on the client specific value of the target client, the channel specific value of the target channel, and a preset weight ratio of the client to the channel, wherein the larger the value of the comprehensive priority, the higher the marking priority.
For example, assuming that the preset weight ratio of the client to the channel is 1:1, after the normalization process, that is, the client occupation ratio is 50%, the channel occupation ratio is 50%, and if the client specific weight of the target client is 8 and the channel specific weight of the target channel is 6, the weighted combined specific weight is (8 × 50% +6 × 50%) (4+3) ═ 7.
For another example, assuming that the preset ratio of the client to the channel weight is 3:1, after the normalization process, that is, the client occupation ratio is 75%, the channel occupation ratio is 25%, and if the client specific weight of the target client is 4 and the channel specific weight of the target channel is 8, the weighted combined specific weight is (4 × 75% +8 × 25%) (3+2) 5.
Of course, the weight ratio of the client and the channel may be set by a user according to user requirements and/or specific application scenarios, and in the embodiment of the present application, no specific limitation is made herein.
