Event-Based Response Time Estimation

Summary, in English

Response time is a measure of quality of service in com-

puter systems. Estimation techniques, suitable for support

systems for mobile phone systems, are explored. These sys-

tems are complex queueing systems with large databases.

The trac generated by users and system adminstrators

changes rapidly, some loads can be measured other cannot.

Attempts to capture all details give models that are not suit-

able for on-line control. Estimators based on continuous

flow models with event based measurements are designed using

extended Kalman ltering. The estimators are compared

with simple-data based estimators.
