Abstract

A provided method provides an assessment of quality of user experience during the loading, on a client, of a web page from a remote server via a network, according to the http protocol, the web page having a root file and at least one reference to a resource, including: a first step including identifying and timestamping the loading of a root file by the client; and a second step including: a step of identifying and timestamping the loading, by the client, of a resource assigned to the root file, a step of processing the timestamps to determine a relative load time of the resource corresponding to the period between the start time of the root file loading and the end time of the loading of the resource assigned to the root file; a step of analysis assessing the user experience in which the relative resource load time is an index.

Claims

1. A method implemented by a system for monitoring an IP network comprising means for capturing frames on said network, in order to provide an evaluation of the experience of a user during a loading, on a client, of a webpage originating from a remote server ia a network, according to the HTTP protocol,

said webpage being constituted by a root file and at least one reference to a resource,

said method comprising:

a first step comprising identification and timestamping, by said system for monitoring an IP network, of a loading of a root file by said client;

a second step implemented by said system for monitoring an IP network comprising;

a step of identification and timestamping of a loading, by said client, of a resource which is assigned to said root file;

a step of processing said timestamps in order to determine a relative load time of said at least one resource corresponding to the period between the start time of the loading of said root file and the end time of the loading of said at least one resource assigned to said root file; and

a step of analysis implemented by said system for monitoring the IP network for evaluating the experience of a user in which said relative load time of said resource is an indication.

2. The method according to claim 1, characterized in that the identification of a resource assigned to the root file comprises a processing, by the system for monitoring the IP network, of the content of the “

Referer”

field in the HTTP header of said resource which points to said root file.

3. The method according to claim 1, implemented for a webpage produced on the basis of at least two resources, characterized in that the second step is carried out for at least two of said at least two resources, the at least two relative load times of said at least two resources constituting an indication for evaluating the experience of a user.

4. The method according to claim 3, characterized in that the maximum time from said at least two relative load times (Δ

_r1;

Δ

_r2) constitutes an indication for evaluating the experience of a user.

5. The method according to claim 1, characterized in that the step of analysis (A) for evaluating the experience of a user utilizes a determination of a relative load time (Δ

_rn) of the last resource called by the root file.

6. The method according to claim 1, characterized in that it is implemented for detecting a change in the experience of at least one user during a loading, on a client (108), of a webpage originating from a remote server via a network, according to the HTTP protocol.

7. The method according to claim 6, characterized in that it comprises moreover a step of storing the experiences of the user over time and an analysis of the change in this experience.

8. The method according to claim 1, characterized in that it comprises moreover a step for detecting an abnormal change in the relative load time on the basis of statistical data acquired during the course of earlier implementations of said method.

9. A system for monitoring an IP network, comprising means for capturing frames on said network, implementing the method according to claim 1.

10. The system according to claim 9, implemented for comparing relative load times of one and the same webpage originating from a server, for a plurality of clients.
