“…Within the Charging and Accounting Technology for the Internet (CATI) [8] project we have developed a prototype system [9,10] to demonstrate dynamic establishment of QoS-enabled VPN tunnels that is also capable of generating user billing information. The central component, the service broker (SB), plays the role of the policy server.…”

New emerging IP services based on differentiated services and the IP security architecture offer the level of communication support that corporate Internet applications need nowadays. However, these services add an additional degree of complexity to IP networks which will require sophisticated management support. The management of enhanced IP services for their customers is thus an emerging important task for Internet service providers. This article describes a potential management architecture service providers will need for that task, considering problems such as multiprovider services and service automation. We will focus on a quality-enhanced virtual private network service which is particularly useful for corporate internetworking.

“…The CA first finds the identity of the called party (i.e., Bob), as well as the location of Bob's Preference Registry, using the Name Mapping service. It finds Bob's preferred endpoint, and returns an appropriate iPOP for reaching the callee 8 , from his Preference Registry. The callee iPOP also interacts with the CH for resource reservation, admission control and accounting.…”

Abstract-In the ICEBERG project at U. C. Berkeley, we are developing an Internet-based integration of telephony and data services spanning diverse access networks. Our primary goals are extensibility, scalability, robustness and personalized communication. We leverage the Internet's low cost of entry for service creation, provision, deployment, and integration. In this article, we present our solutions to signaling, easy service creation, resource reservation, admission control, billing and security in the ICEBERG network architecture.
