Abstract: Geographically distributed data-gathering client computers are connected to the Internet in the same manner as typical users (for example, via local dial-up connections). The data-gathering client computers poll a central server (the “UserMon” server) for a target site to access. After receiving the address of a target site from the UserMon server, the data-gathering client computers access the target site and obtain performance-parameter values indicative of the quality of their respective Internet connections to the target site and/or the performance of the target site itself. Each data-gathering client computer then pushes the performance-parameter values back to the “UserMon” server for analysis.

Abstract: A system for recording and replaying Internet transactions is disclosed. The system uses a recorder object that connects between the Internet and an Internet client through the Internet client's proxy server interface. All communications between the Internet client and the Internet pass through the recorder object, and the recorder object is therefore able to observe directly the exact content of the communications, as well as other aspects of the communications, such as the rate at which they take place, the number and size of packets into which they are bundled, errors in communication, and DNS resolution time. This information can be used to produce a detailed record of the transaction, which can then be reproduced by an Internet client which is configured to use the record to replay the recorded transaction.
