Specifically, an embodiment of the present invention provides a bandwidth control method, as shown in fig. 2, where fig. 2 is a schematic diagram of a first flow of an embodiment 1 of the bandwidth control method of the present invention, and the method includes:
step S210, measuring the data packet length of the data packet to be transmitted;
specifically, length measurement is carried out on an input data packet to be transmitted, and the length of the data packet can be obtained; preferably, the data packets to be transmitted are counted by using the clock period of the working clock, and the obtained counted number can be the length of the data packets to be transmitted; further, after obtaining the length of the data packet, the length of the data packet can be recorded to a specified position;
it should be noted that the data packet to be transmitted may be a data packet to be transmitted to the ethernet;
the length of the data packet can be measured or calculated in bytes, for example, the physical characteristics of the ethernet determine that the maximum length of a link layer data frame is 1500 bytes, a longest IP packet can be 65535 bytes, and the like;
step S220, based on the length of the data packet and the preset bandwidth, generating an output ratio and idle data packets for separating the data packets to be transmitted in the transmission process; the output ratio is the data packet length ratio or the number ratio of the data packet to be transmitted and the idle data packet;
specifically, generating an idle data packet and an output ratio according to a preset bandwidth by the length of an input data packet;
it should be noted that the preset bandwidth may be used to set the bandwidth size or the rate according to the actual need, and may be obtained by the system configuration parameters; specifically, such as full speed, cutout, half speed, 1/4 rate, 1/5 rate, 1/8 rate, etc.; the embodiment of the invention achieves real-time adjustment of the parameters by dynamically adjusting the bandwidth parameters in real time without restarting the system;
the idle data packets can be idle invalid data packets or idle characters and can be used for controlling the interval of each data packet to be transmitted in the transmission process; specifically, a corresponding idle data packet can be generated according to the length of the data packet to be transmitted and a preset bandwidth, and the idle data packet can be used for separating the data packets to be transmitted in the transmission process, so that the bandwidth parameters can be dynamically adjusted in real time without restarting the system;
