1 J. Fiedler (Fraunhofer FOKUS) ENUM-Day 2008, DENIC, Frankfurt, April 18th, 2008 Modern NGN Testbeds Experiences from FOKUS Technology Playgrounds and the Way forward to Interconnected National and Pan-European Testbeds Jens Fiedler Fraunhofer FOKUS Jens.fiedler@fokus.fraunhofer.de 1

2 Evolution towards Converged Networks Fixed Networks PSTN ISDN Information DSL Technologies Mobile Networks Internet SMS WiFi WiMax WAP Analogue GSM UMA GPRS UMTS HSDPA FTP WWW Portals ENUM Web2.0 P2P IM VoIP IPTV itv FMC Triple Play Converged NGN Quad Play VoD Content Sharing Cable Networks Broadcast Home Networks 2

3 Open (Research) Testbeds The new multimedia service world on top of converging networks is complex and expensive Value chain evolution: Networks Services Network technlogies become less important Operator specific or vendor specific testbeds are not sufficient Learn from the internet: an open infrastructure is needed Open Testbeds are needed to stimulate academia and industry Adequate software toolkits (open source) is needed Research testbeds (proof of concept) versus industry testbeds (interoperability) 3

4 Shift from Networks to Service Orientation Historically services have been network specific IP-fication unifies networks conceptually = competition is on services! Internet shows what multimedia services can be = Web 2.0, but where is the money? Research: Edge Intelligence (Peer2Peer) vs. Network Intelligence (Autonomic Communications) vs. Legacy migration Service Orientation of infrastructures requires application programming interfaces & toolkits & testbeds Service Oriented Architecture New Information Technologies Multimedia Applications & Content (3rd Parties / Consumers) Reusable Service Components / Service Enablers Tool kits Network Abstraction / Application Programming Interfaces Open Source New Network Technologies Legacy Telecoms Peer2Peer Autonomic ClassicEnd2End Communications Internet Testbeds 4

8 J. Fiedler (Fraunhofer FOKUS) ENUM in an NGN Testbed ENUM offers a standardized DNS driven, distributed directory for services. Many synergies between ENUM and IMS Mapping of ENUM services to IMS services and vice versa is possible. ENUM = Repository of services for NGN users.

9 A Case Study: German Service Line 115 Based on IT Summit in Potsdam December Definition of Serviceline 115 Concept Feasibility Study on FOKUS Testbeds for CeBit Fair March 2007 and continuous functional extension since then egovernment Lab operated by the FOKUS Competence Center ELAN Open IMS Playground yground/index.php?lang=en operated by the FOKUS Competence center NGNI Start of Industry Partnering around Testbed Definition of the Deutschland Online Project More Info about this reference project: ekte/serviceline_115 9

10 Summary Academia AND Industry needs open testbeds! Open also means integration of MANY operators and vendors as partners Open Source helps in lowering the entry barrier for testbed establishment and to achieve a common base for cooperation FOKUS has gained a lot of experiences in testbeds and can contribute a lot IMS Playground SOA Playground AC Lab Panlab / FIRE Interface ENUM can still be part of the ongoing NGN converged network evolution. 10
