Network state data acquisition method and system

Abstract

The invention discloses a network state data acquisition method and system. The acquisition method comprises the following steps: (1) detecting and recording RTT data of a user in real time; (2) detecting and recording bandwidth data of a user in real time by utilizing a blocking type bandwidth detection method, and recording network flow consumed by the user, wherein in the bandwidth detection process, if network congestion does not occur, the sending data volume is increased on the basis of the original sending data volume, and the downlink bandwidth of the user is judged according to the network congestion state; (3) recording the IP address and geographic positioning of the user; (4) classifying the users according to the IP addresses and geographic positioning of the users, and classifying the recorded RTT data and bandwidth data according to user classification; and (5) processing the data obtained by classification to generate an actually available data set. According to the method and the system provided by the invention, the accuracy and efficiency of network state measurement are improved, and the consumption of user traffic is reduced.

Description

Technical field [0001] The invention relates to network detection technology, in particular to a data collection method and system for network conditions. Background technique [0002] With the gradual popularization of the Internet and the continuous improvement of network communication technology, users' demand for high-quality networks is increasing. Many daily Internet applications rely on the stability of the network. In order to improve the user's actual experience, it is necessary to know the network status between the server and the client and make corresponding adjustment strategies. For example, when users watch live video, due to user bandwidth fluctuations, the video data in the buffer is not enough to support smooth playback, and the video bit rate is too large to cause network congestion. The server usually adopts ABR technology (Adaptative-Bitrate). Measure and estimate user bandwidth, dynamically adjust video bit rate, reduce bandwidth requirements, and achieve t...

AI Technical Summary

Problems solved by technology

The UDP packet sending algorithm can accurately measure the user's bandwidth, but sending a large number of data streams will cause network congestion and affect user experience

For the existing RTT measurement method, due to the limited CPU processing capacity, the priority of data flow and other factors, it is impossible to achieve high concurrent processing of the server under the premise of low measurement interval

[0004] Therefore, the current network status collection system generally has defects such as large traffic, high collection time, and low concurrency.
