Architecture for the creation of service level agreements and activation of IP added value services

The pervasive influence of the Internet as long as the insatiable desire for bandwidth have led the researchers to promote massive and disruptive changes within the Internet technology. The end goal is to enable the rapid development of a wide variety of services and support them in a unified and consistent manner. As far as the customer view is concerned, means for specifying dynamically the services each customer wishes to be subscribed offered by an ISP are needed. Moreover an IP QoS signaling protocol is required in order for the customer to activate added value services. We propose system architecture for dynamic service subscription based on a negotiation strategy and an approach for explicit activation of services. These models offer the customer an automated manner to specify, select, negotiate, activate and make use of added value services with specific characteristics. The novelty of the proposed approach is the reduction of the operational cost of an ISP and the time needed for a customer to request and access services.
