Techniques for server-controlled measurement of client-side performance

Abstract

Techniques for measuring client-side performance include intercepting an item that is to be sent to a client process prior to the arrival of the item at the client process. The item is modified to produce a modified item that includes code. The code causes a processor on the client device to measure performance related to a service associated with the item. The code also causes the processor to perform one or more acts based on a measurement resulting from measuring performance. The modified item is sent to the client process. These techniques allow a service provider to automatically modify an item each time the item is sent to a client process, dispelling cumbersome steps in installing and maintaining software on a client device. The modifications may be made transparent to a designer of the server application and thus easily applied to both new and existing server applications. These techniques also allow the service provider to obtain measurements of actual performance experienced by the real users and without placing a spurious load on the website. The code in the modified item can be tailored to provide any response desired, from reporting those measurements to the service provider for analysis by the service provider, to automatically notifying the user of the client process, to automatically diagnosing the cause of unfavorable performance such as by correlating performance problems with particular components of the client process.

Description

technical field [0001] The present invention relates to the measurement of the performance of the network client which obtains the service from the network server, and particularly relates to the technique of controlling the measurement and response of the performance of the network client related to the provided service. Background technique [0002] Many businesses hope to use the Internet to gain access to a rapidly increasing number of agents and customers. The Internet is a public network composed of multiple computer networks, each of which has one or more nodes. The Internet utilizes open standard protocols to address nodes and to transfer information from one node to another. A user accesses the Internet, usually owned and operated by an Internet Service Provider (ISP), by logging on to a computer on a network. Typically, users establish a severable link between their computer and the ISP's computer. A client application (client process) running on a user computer...

Thus, the agent itself contributes to perceived performance degradation

Also, the simulated agent method adds additional traffic on the network in order to report the estimated client response time to the service provider
