Method and device for monitoring network traffic

Abstract

Disclosed are a method and apparatus for monitoring network traffic, the method comprising: obtaining configuration data of user configuration, wherein the configuration data includes a rate limit; obtaining a time period corresponding to the interval of the configured rate limit according to a corresponding relationship between a preset rate limit interval and a time period for adding a token, wherein in the corresponding relationship above, the larger the value of the rate limit interval, the shorter the corresponding time period; updating the time period for configuring a token bucket and adding a token to the obtained time period; monitoring the network traffic by using the token bucket. According to the present invention, the algorithm precision of the token bucket is improved, thus rate limiting precision is enhanced.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to a network traffic monitoring method and device. Background technique [0002] Due to the continuous development of the network, more and more services are carried on the network, and the requirements for bandwidth are getting higher and higher. However, bandwidth resources are limited. How to maximize the rational use of limited bandwidth resources is the most important concern of network service providers. of the problem [0003] In order to use it reasonably, it is necessary to properly monitor the current network traffic. The token bucket technology is currently the most common network traffic monitoring technology. Based on this technology, the traffic in the network can be classified according to different classification rules, and all kinds of traffic Restrictions are made according to different strategies to maximize the fair utilization of the network. ...

AI Technical Summary

Problems solved by technology

Among them, the first method is simple and easy to implement, but how to determine the cycle of adding tokens is a complex problem, and there is no optimal solution

Although the second method solves the problem of calculating the time period of the first method, when the traffic is very large, each message calculates the token, and the limited processing cycle will be wasted

[0008] In the related technology, due to the low accuracy of the token bucket algorithm, which leads to inaccurate actions taken on network supervision, thereby reducing user performance, no effective solution has been proposed so far.
