Description

Method and client for realizing flow control

Technical field

The present application relates to, but is not limited to, a communication device data processing technology, and more particularly to a method and a client for implementing flow control.

Background technique

In order to ensure that the limited network bandwidth resources are fully utilized, flow control technology is widely used in communication networks. The main function of the traffic control technology used in the existing device (such as the client or the server) is to control the data rate of the uplink data on the terminal side to be smaller than the uplink communication rate, and control the data rate of the downlink data to be smaller than the downlink communication rate. It is well known to those skilled in the art that flow control can be implemented using existing token bucket technology.

Taking the client running the operating system as an example, the function of the client is usually implemented by the hardware and software of the client. According to the functional software can be divided into operating systems, drivers and applications. It is well known to those skilled in the art that an operating system is a basic platform for implementing drivers and applications, and an operating system implements cooperation with hardware through a driver. After the client is powered on, start the operating system. The boot process of the operating system is roughly divided into: the boot phase and the system load phase. In the system loading phase, load system programs and drivers, set the system operating environment, and so on. After the system loading phase, the operating system finishes booting, usually loading pre-configured applications.

For existing clients running the operating system, the flow control of the client, such as the flow control unit in the LINUX operating system, needs to be configured and activated by the application (such as an agent) loaded after the operating system is started, and then flow control. That is to say, flow control cannot be performed during the startup of the operating system. Take the network diskless system as an example. During the startup process of the operating system, the client needs to perform a large amount of data interaction with the server to obtain the data required for the operating system startup from the server. If a large number of clients are started at the same time, the server will be enabled. It is necessary to transmit corresponding data for each client that is started at the same time, which will cause network congestion between the client and the server, and also cause the server load to be multiplied or even down, thereby reducing the stability of the server and the network. Sex.
