Reliability Measure in Content-Distribution Systems

Abstract

As the telecommunications industry has rapidly evolved, its software functions continuously advance. These changes have to be reflected in all client software before new services can be introduced. An inconsistent system in which client software fails to receive updated content delivers no new service to customers, causing loss of revenue, customers and even goodwill. Therefore, a reliable content delivery service is needed for such a large-scaled service companies to guarantee system consistency. This investigation analyzes the queueing model of a proposed content delivery service and derives the measure of system reliability.
