Abstract

The invention discloses a method and a device for calculating packet loss rate as well as a method and a device for controlling network transmission, belonging to the field of network transmission quality control. The packet loss rate can be calculated and the network transmission quality can be improved under the circumstances of network bandwidth fluctuation. The method for calculating the packet loss rate comprises the following steps of: calculating the packet loss rates of multiple time periods within a preset time range, and calculating the change rate of the packet loss rate of each time period relative to the packet loss rate of the previous time period; judging whether the change rate is in a preset first value range, and acquiring the packet loss rates with the change rates in the preset first value range; and calculating the average value of the packet loss rates acquired within the preset time range. The methods and devices are mainly used for detecting and controlling network transmission quality.

Description

technical field [0001] The invention relates to the field of network transmission quality control, in particular to a method and device for calculating packet loss rate, and a method and device for controlling network transmission. Background technique [0002] With the continuous expansion of network applications, the quality of network transmission is becoming more and more important. In order to improve the quality of network transmission, we must first detect the quality of network communication. There are many methods for detecting network communication quality. The method of detecting network communication quality by calculating the packet loss rate is a basic, easy-to-implement, and important method. method. [0003] In the traditional method of calculating the packet loss rate, the packet loss rate is obtained by calculating the number of packet loss. That is: the number of lost packets is obtained according to the number of packets received by the receiving end, a...

Problems solved by technology

[0004] The above method of calculating the packet loss rate is relatively simple, but only in a relatively stable network environment can it reflect the quality of network communication more accurately

However, many networks in reality are not very stable, and there will be more bandwidth fluctuations

For example, in some wireless networks, the strength of the signal is related to external factors such as weather. Affected by external factors, the transmission bandwidth will fluctuate for a short time, making the packet loss value during network transmission deviate from the packet loss during normal network communication. value

According to the above method of calculating the packet loss rate, it is impossible to exclude the sudden change in the packet loss rate when the bandwidth fluctuates, resulting in the inability to accurately obtain the packet loss rate, which leads to wrong judgments on the quality of network communication, and thus cannot effectively improve network transmission. quality
