From the Queue to the Quality of Service Policy: A Middleware Implementation

Free registration required

Executive Summary

Quality of service policies in communications is one of the current trends in distributed systems based on middleware technology. To implement the QoS policies it is necessary to define some common parameters. The aim of the QoS policies is to optimize the user defined QoS parameters. This paper describes how to obtain the common QoS parameters using message queues for the communications and control components of communication. The paper introduces the "Queue-based Quality of Service Cycle" concept for each middleware component. The QoS parameters are obtained directly from the queue parameters, and Quality of Service Policies controls directly the message queues to obtain the user-defined parameters values.
