Economic analysis of QoS differentiation in OPS networks
Quality of Service (QoS) differentiation is the differentiated traffic-handling to
achieve multiple service classes of varying quality. In addition to providing service
guarantees necessary for delay-sensitive, real-time applications, service differentiation can provide increased income for network providers due to price differentiation opportunities. Moreover, with advances in technology, previous QoS schemes based on buffered networks cannot be used in newer, bufferless, optical networks.
Current and future technologies were studied to facilitate economic analysis of
QoS differentiation in Optical Packet Switched networks. Empirical data from
related studies have been adopted to quantify a relationship between objective
measurements of network quality and a users willingness to pay for that quality.
Models that represent network scenarios with and without service differentiation
were discussed to address the viability of implementation. The model developed
suggests pricing for customer classes based on network parameters before and after implementation, cost of deployment, customer willingness to pay, and business
requirements such as Return on Investment. It was determined that under certain
circumstances, a network provider may improve revenue via service differentiation.
