The project Market Managed Multi-service Internet (M3I) aimed at the design, implementation, and trial of a new generation system enabling Internet resource management through market forces.
The areas of major interest to ETH Zürich, TIK included for the second reporting period of this project (1) the implementation of a Charging and Accounting System (CAS) for a distributed provider scenario of Internet Service Providers, (2) based on the definition of a cost model for Internet Service Providers (ISP) its application in a case study for a hypothetical Swiss-wide research network, and (3) the definition, evaluation, and implementation of a long-term pricing scheme for differentiated services, termed Cumulus Pricing Scheme (CPS).
The designed CAS has been implemented in JAVA in a modular fashion. Based on the list of features and tasks as well as system requirements the resulting implementation has been successfully integrated with other partner's code as well as the CPS, which formed the basis for the existing prototypical implementation. ETH Zürich, TIK input to the final M3I architecture had been completed based on the CAS experiences obtained during the life-time of the project. This M3I architecture integrates the CAS as well as other components developed by M3I, such as the price communication, which had been demonstrated in the official EU project review.
The cost model developed by ETH Zürich for ISPs had been applied in a case study on a hypothetical Swiss-wide research network, where a number of possible projections have ben performed to show that the cost model provides results, which enable an ISP to determine a.o. prices for their services offered.
Driven by the theoretical definition of the developed Cumulus Pricing Scheme (CPS) it has been implemented in a test-bed, applying the CAS and the M3I architecture. It has been shown that CPS as a flat rate scheme, founded on Service Level Agreements, offereing dynamic and individual adaptations of their flat rates on long time-scales behaves similarly in a simulation environment and an implementation test-bed. Therefore, the proposal of CPS solves successfully the Feasibility Problem of Internet charging, i.e. the trade-off between technical, economic, and user-based requirements.
