Service quality on computer and network systems has become increasingly important as many conventional service transactions are moved online. Service quality of computer and network services can be measured by the performance of the service process in throughput, delay, and so on. On a computer and network system, competing service requests of users and associated service activities change the state of limited system resources which in turn affects the achieved ...
To provide Quality of Service (QoS) demanded by many online services (e.g., e-commerce), computer and network systems need to have QoS monitoring and adaptation which must be based on cause-effect dynamics relations among service activities, the state of system resources, and the QoS performance of service processes. This paper presents our study on cause-effect dynamics models for one of computer and network services, the voice communication service with the throughput ...
