| Abstract: |
The objectives of the CATI project (Charging and Accounting Technology for the Internet), consisting of CAPIV (Charging and Accounting Protocols in the Internet and in Virtual Private
Networks) and MEDeB (Management, Evaluation, Demonstrators, and Business Models), include the design, implementation, and evaluation of charging and accounting mechanisms for Internet services
and Virtual Private Networks (VPN). They develop the enabling technology support for open, Internet-based Electronic Commerce platforms. Their main components encompass usage-based transport
service charging methods of high-quality Internet transport services as well as methods for advanced and flexible configurations of VPNs. To complete a real-world applicable solution,
security-relevant and trust-related issues in charging, accounting, and billing processes are integrated. Furthermore, the investigation and development of pricing and cost models for Internet
services is performed to obtain practical experiences in incentive-compatible dynamic pricing models. This work is complemented by important application scenarios, such as an Internet telephony
application as well as an Electronic Commerce scenario, in order to demonstrate the applicability and efficiency of the developed approaches. |
