Main objective of DIANA project
The main objectives of the DIANA project are to develop, integrate, validate and demonstrate resource reservation and traffic control functionalities which seamlessly interoperate between ATM and IP networks to achieve QoS. At the boundary between the ATM and IP domains, DIANA translates between RSVP and ATM signalling, thereby supporting the different QoS specifications of IP and ATM. DIANA also experiments with novel techniques, based on differentiated services methodologies.
The developments in DIANA allow the investigation of different approaches for the convergence of RSVP/IP and ATM, as well as providing an insight into the feasibility and efficiency of this topology and the optimum sizes of the two domains.
DIANA investigates, implements and demonstrates approaches which encompass IP to ATM translation and real integration. DIANA specifies and develops a generic network infrastructure including native ATM and Next Generation IP domains, which both offer guaranteed services; the latter based on the RSVP (Resource ReSerVation Protocol) specification and the latest outputs from the IETF Integrated Services Working Group (in the direction of differentiated services). By prototyping a RSVP/IP/ATM Integration Unit, end systems will have the choice to act either as RSVP/IP or ATM entities according to their preferences or capabilities.
Swiss contribution
There are multiple organisations from Switzerland (ASPA, Ascom, Swisscom, EPFL and Telscom ) participating in this project.
DIANA demonstrated several options for handling IP traffic with varying quality of service requirements, taking into account both ATM and non-ATM underlying networks. Some of the methods enhance current schemes (eg. RSVP-over-ATM), by including aggregation and efficient resource re-negotiation, or are combinations of current schemes, such as the heterogeneous RSVP and Differentiated Services case, as demonstrated in conjunction with ELISA (another ACTS project). Other demonstrations from DIANA are premières for new techniques, such as the Scalable resource Reservation Protocol (SRP), and the Simple Integrated Media Access (SIMA).
Telscom participated in developing system architecture from the applications point of view by analysing different applications with respect to QoS, network performance and interworking issues.
In the development area, TELSCOM developed peer-to-peer interworking for the applications common to ATM and IP technologies for audio and video streaming applications which was integrated in the Basel testbed and later demonstrated during TELCOM'99.
Telscom was also responsible in co-ordinating the integration and tests. The ATM/IP interworking was demonstrated successfully during the Telecom'99 conference. DIANA had established close links with other related projects to demonstrate the convergence trials
DIANA was leading the ATM/IP cluster within the NI Chain group and was responsible as editor in developing 2 Guidelines.
