Abstract
A framework is developed for performance analysis of an integrated model of multiple class-of-service Internet. An Internet service provider is considered who provides premium, assured and best-effort services to end-users. Various aspects of the model are studied including link bandwidth allocation/sharing policies, user behaviours and service price-quality structure design. An analytic Markov model is developed and equilibrium performance measures are derived. Based on the analytical model, numerical analysis demonstrates the importance of trunk reservation in providing service protection and bandwidth sharing and the effects of user behaviours on service price and quality design. To get more insight on service price and quality design, two service quality declaration mechanisms are studied, i.e. static and dynamic service quality declarations under the assumption of static pricing. Simulation results show that the dynamic service quality declaration offers better performance when traffic level/pattern varies.
