The main goal of the CATI project has been the design, evaluation and implementation of charging and accounting mechanisms for value-added Internet services such as Integrated Services, Differentiated Services and Virtual Private Networks (VPNs). CATI was a CNEC (Competence Network Electronic Commerce) project within the Swiss Priority Program for Information and Communications Structures (SPP ICS) of the Swiss National Science Foundation (SNF) running from July 1998 to March 2000. The RVS group developed a flexible VPN service system including Quality-of-Service (QoS) support. The user can set up, modify and tear down VPN connections on-line and choose from IP Security features for the VPN service as well as QoS features similar to the IETFs Differentiated Services. The developed system supports both Cisco and Linux routers and handles accounting of VPN connections considering bandwidth, duration of the reservation, time of day, security parameters etc. To support Integrated Services applications, a gateway has been implemented on Linux for mapping Integrated Services to Differentiated Services reservations. Automatic set up and management of VPNs between the universities of Geneva and Bern as well as the Integrated / Differentiated Services gateway using an RSVP capable video application have been demonstrated successfully during the final SNF CNEC workshop in March 2000 at Bern. In addition, bandwidth broker protocols have been developed and implemented in order to support multi-provider VPN services.
