Abstract

Performance monitoring of network connections is an integral and necessary part of network operation, administration and management. The performance monitoring reflects the “goodness” of the communication system in supporting “high-level” data communication services to end-users. This is done by quantifying the perception of an end-user and using this quantification as a guideline for the capability of the network to provide communication services. The computer implemented process is a user-friendly, automated collection and tabulation of performance measurements that directly reflects the perception of an end-user on the capabilities of the underlying communications network. The disclosure is geared toward the “Web-centric” Internet world, but the method can be adapted to non-Internet communication systems.

Claims

1. In a computer communications system where subscribers receive interactive data services on client computer systems from server computer systems, both the client and server computer systems being attached to the communications system, a computer process executed by a client computer system that acts as a virtual subscriber to the data services supported by the said communications system comprising the steps of:

emulating by the virtual subscriber the interactive behavior of regular said subscribers to said data services; and

collecting information related to the performance of communication links between said client and server systems, said collected information being responsive to said emulating step and being registered by the virtual subscriber.

2. The computer process recited in claim 1 wherein said communication system has multiple client computer systems executing copies of said virtual subscriber process.

3. The computer process recited in claim 2 wherein each said virtual subscriber process being capable of requesting data services from any number of respecified data servers and collecting information related to the performance of said communication links between said client and server systems, said collected information being related to each said request for service.

4. The computer process recited in claim 3 further comprising the step of controlling each said virtual subscriber process and altering its said interactive behavior via another computer process executing either on the same client computer system executing the said virtual subscriber process or located remotely from the client computer system executing said virtual subscriber process.

5. The computer process recited in 4 wherein said information related to the performance of said communication links between said client and server systems collected by each said virtual subscriber process is accessible and viewable via another computer process executing either on the same client computer system executing the said virtual subscriber process or located remotely from the client computer system executing the said virtual subscriber process.
