Inter-domain routing algorithms that maximize users´ benefit in an Internet business model

We define a business model for a future Internet able to provide customers with a wide variety of application services, which typically need performance guarantees. The reference environment includes a number of entities: customers, network and application service providers, resource and information brokers, and a clearing house. Assuming usage-based tariffs to charge for IP guaranteed services, we propose inter-domain routing algorithms for determining the path along autonomous domains, with the aim of maximizing users´ benefit, in terms of QoS perceived and price to be paid.
