Objective EXPERT is enhancing the RACE II testbeds of EXPLOIT and TRIBUNE with new ATM access equipment, including an ATM Passive Optical Network and an integrated service CPN switch, making it even more representative of a future broadband network. The platform is being used to determine critical factors in ensuring integral ATM network performance, i.e. the integration of different service types (real-time and non real-time) and their control to ensure the maintenance of end-to-end QoS. A major role of the platform is also the support of the ACTS Programme, through the participation in European and inter-continental trials and the hosting of other ACTS projects in order that they can fulfil their objectives.EXPERT is already validating and demonstrating the ability to maintain end-to-end QoS in a mixed (real-time and non real-time) environment (including ABR) through the implementation of a range of integrated traffic control functions including signalling, Connection Admission Control, Usage Parameter Control, routing mechanisms and resource management schemes.The platform is already being used as the basis for several ACTS projects to validate their own results, and also to facilitate inter-Programme, international and inter-continental trials.The platform with its wide variety of broadband equipment, also serves as a practical showcase for the ACTS Programme as a whole.Expected ImpactBy providing an well-organised substantial platform for the purpose of making Operation Trials within Europe and abroad, EXPERT contributes significantly to the ACTS Programme. Its own hardware and software developments are in areas which are critical in order to turn ATM technology into commercial services. The many issues surrounding the exploitation of statistical multiplexing are also being evaluated in EXPERT to give PNOs vital information for the dimensioning of networks and users confidence that requested QoS can be maintained.Main contributions to the programme objectives:Main deliverablesAdvanced broadband signalling capabilities and their usage for providing QoS to IP applications and for Video-on-Demand selection, with dynamic bandwidth allocation implementations for resource management developed an open interface between access and core networks.Contribution to the programmeAdvanced knowledge in key aspects of broadband communications, which fed into both standards (especially ETSI) and the development of commercial products from European manufacturers. The project also supported others in their experiments, validations and demonstrations and played a major role in all EU distributed conferences, enabling the linkage from Europe to Canada and Japan.Technical ApproachThe EXPERT platform now contains 14 ATM switches, ATM/N-ISDN and ATM/Frame Relay interworking units, medium adapters to enable cells to be transported over PDH transmission systems, the support of 2 Mbit/s circuit emulation, terminal adapters for the attachment of standard workstations, PCs, TV and video equipment (including 3-D), CD-audio and N-ISDN terminals. Current versions of ITU-T and ATM Forum signalling schemes are also installed, and will be upgraded during the lifetime of the project. ATM access equipment (including an ATM Passive Optical Network) and an integrated services switch have been developed within the project and recently integrated into the platform. New interworking capabilities to mobile networks, will be contributed by projects with which EXPERT is collaborating.Multimedia applications and sophisticated traffic generation and analysis equipment (including a new network performance evaluation tool) will be used to demonstrate the optimal integration and control of a wide variety of traffic sources.Available Applications:BaselISABELPC audio/video (M-JPEG)N-ISDNPC data retrievalTV/Video (CBR)H. 261 codingCD AudioLeidschendamISABELN-ISDNJVTOS and MMMSPC audio/video (M-JPEG)"In-Person"PC multimedia retrieval"Cinebase" video retrievalH.261 coding3-D video (MPEGII)Summary of TrialThe collection of broadband facilities offered by EXPERT (applications, terminal equipment, ATM switches, signalling capabilities and network interworking units) is unique in Europe. The EXPERT project will therefore provide the platform for a number of trials to be performed by other ACTS projects in the fields of mobile, multimedia (in the Finnish Multimedia Programme), charging and signalling for ATM, telecommunication and CATV network integration, tele-learning and TMN aspects.Own project developments will enable trials of cost-effective ATM access and multi-service integration to take place. With the development of a new network performance evaluation tool the project is also validating traffic engineering aspects for optimising the utilisation of broadband network resources.Through the involvement of common partners, EXPERT expects to make joint trials with the Swiss, Dutch, Finnish, UK, Danish and Norwegian National Hosts. EXPERT is currently taking part in the G7/GIBN application trial for "Virtual Classrooms" in conjunction with similar broadband facilities of the "CANARIE" testbeds in Canada .Successful trials for the distribution of large data files, collected by satellite, to sites in Europe have also already been carried out with the DGXII "Centre for Earth Observation"; further trials are expected.Key IssuesIntegral network performance (the combination of source parameters, traffic control and resource management schemes)End-to-end QoS (under mixed traffic conditions)Cost-effective flexible ATM access equipment (an ATM Passive Optical Network)An integrated services switch for the CPN environmentBroadband signalling (ATM Forum and ITU-T)Support of other ACTS projects and Operational TrialsInter-Programme, international and inter-continental collaborationValidation of new features and their transfer into commercial operation (e.g. via National Hosts)Raising the awareness of broadband communication capabilities Fields of science engineering and technologymechanical engineeringvehicle engineeringaerospace engineeringsatellite technologyengineering and technologyelectrical engineering, electronic engineering, information engineeringinformation engineeringtelecommunicationstelecommunications networksmobile networknatural sciencescomputer and information sciencessoftwaresoftware developmentengineering and technologyelectrical engineering, electronic engineering, information engineeringinformation engineeringtelecommunicationstelecommunications networksoptical networks Programme(s) FP4-ACTS - Specific programme of research, technological development and demonstration in the area of advanced communications technologies and services, 1994-1998 Topic(s) 3 - High speed networking Call for proposal Data not available Funding Scheme CSC - Cost-sharing contracts Coordinator ASPA Address Berner technopark, morgenstrasse 129 3018 Berne Switzerland See on map EU contribution € 0,00 Participants (28) Sort alphabetically Sort by EU Contribution Expand all Collapse all Alcatel BELL Belgium EU contribution € 0,00 Address See on map Alcatel STR Switzerland EU contribution € 0,00 Address See on map Ascom Tech Switzerland EU contribution € 0,00 Address See on map Association Swiss Telecom PTT/Ascom Switzerland EU contribution € 0,00 Address See on map Deutsche Telekom Germany EU contribution € 0,00 Address See on map Ecole Polytechnique de Lausanne Switzerland EU contribution € 0,00 Address See on map Helsinki Telephone Company Finland EU contribution € 0,00 Address See on map Intracom SA Hellenic Communications Greece EU contribution € 0,00 Address See on map Italtel Società Italiana Telecomunicazioni SpA Italy EU contribution € 0,00 Address Castelletto di settimo milanese 20019 Milano See on map Laboratoire d'Electronique de Philips France EU contribution € 0,00 Address See on map Lake Communications Ireland EU contribution € 0,00 Address See on map Lucent Technologies Netherlands EU contribution € 0,00 Address See on map Mikroelektronik Anwendungszentrum Hamburg Germany EU contribution € 0,00 Address See on map NATIONAL TECHNICAL UNIVERSITY OF ATHENS Greece EU contribution € 0,00 Address See on map Nokia Finland EU contribution € 0,00 Address See on map Queen Mary and Westfield College United Kingdom EU contribution € 0,00 Address Mile end road E1 4NS London See on map Royal PTT Nederland, KPN Research Netherlands EU contribution € 0,00 Address See on map Simulog France EU contribution € 0,00 Address See on map Technical University of Cluj - Napoca Romania EU contribution € 0,00 Address See on map Technical University of Dresden Germany EU contribution € 0,00 Address See on map TeleDanmark Denmark EU contribution € 0,00 Address See on map Telefónica de España Spain EU contribution € 0,00 Address See on map Telenor Research and Development Norway EU contribution € 0,00 Address See on map Teltec Ireland EU contribution € 0,00 Address See on map UNIVERSITAET STUTTGART Germany EU contribution € 0,00 Address Holzgartenstrasse 17 70049 Stuttgart See on map UNIVERSITAT POLITECNICA DE CATALUNYA Spain EU contribution € 0,00 Address Jordi girona 31 See on map UNIVERSITY OF ANTWERP Belgium EU contribution € 0,00 Address Prinsstraat 13 See on map University of Ghent Belgium EU contribution € 0,00 Address See on map
