Passive network performance measuring system and page identification method thereof

Abstract

The invention provides a passive network performance measuring system and a page identification method thereof in the computer network technology field. The system comprises a network trace acquisition module, a webpage element parsing module, a webpage identification module and an information statistics module. In the invention, a passive network measuring mode is employed, a trace acquisition point is provided in a network access link to obtain original measuring data without running a measuring code on a user computer or bringing extra flow to a network because of measurement to influence a normal service in the network. According to a measuring method of a user side Web performance, a load time of a single page is taken as a measuring index which can directly reflect a real experience of the user. By employing an improved page identification method, by utilizing webpage elements of an HTTP request, a hyperlink association graph between the webpage elements is drafted, combined with structure characteristics of different webpages at different websites, a complete webpage is separated from the hyperlink association graph, a page of a coincidence load time can be identified, and accuracy of page identification is raised.

Description

technical field [0001] The present invention relates to a system and a method in the field of computer network technology, in particular to a passive network performance measurement system and a page identification method for user-side Web performance in units of pages. Background technique [0002] The object of application performance measurement is the performance index of a specific application, such as the availability of the application, the response time of the application service, the popularity and distribution of the application, and so on. Traditional network performance measurement (network performance measurement), the measurement object is mainly the basic performance indicators of the network, such as network delay, packet loss rate, link bandwidth, available bandwidth and so on. However, in many cases, the availability of the network does not represent the availability of the application, and the delay of the network cannot directly reflect the response time ...

AI Technical Summary

Problems solved by technology

This association graph method simplifies the data structure and is conducive to the realization of low-consumption algorithms, but there is currently no literature that applies this method to the measurement of user-side Web performance

Different from network prediction, the measurement of user-side web performance is no longer faced with resources in a single website, but with different types of webpages in different websites. identify different pages well
