Work Brake Down • Workpackage 0: Project Management • Workpackage 1: System Architecture and Traffic Issues • WP1.1 Requirements Analysis (TPSA) • WP1.2 Specification (TPSA, WUT) • WP1.3 Traffic Studies and Engineering (WUT) • Workpackage 2: Prototype Implementation • WP2.1 Service and Resource Control • WP2.2 QoS aware Application and User Services • WP2.3 Distributed QoS Measurements • Workpackage 3: Integration and Trial • WP3.1 System and Network Integration • WP3.2 Trials and Measurements (TPSA, WP leader) • WP3.3 Exploitation and Business Models (TPSA) PTS'2001

  6. Project Meetings and Co-operation • Project Meetings • Project Workshop, Munic, January 2000 • Project Workshop, Darmstadt, April 2000 • Project Workshop, Salzburg, September 2000 • Project Review, Sophia Antipolis, November 2000 • Project Workshop, Dresden, December 2000 • Project Workshop, Warsaw, March 2001 • Project Workshop, Santorini, May 2001 • Next Generation Networks (NGN) Activities • Preparation & Start of NGN Initiative (Thematic Networks Project) • Joint activities of CADENUS, AQUILA & TEQUILA • Submission of IETF drafts on Service Level Specification (SLS) • Presentation at IETF meeting in San Diego, 13.12.2000 PTS'2001

  7. Main objectives of the project • Investigate dynamic end-to-end QoS provisioning in IP networks • Implement prototypes of QoS architecture • Support of wide range of applications by providing a EAToolkit/API • Continuously analyse customer requirements, market situations and technological trends and develop business models • Contribute to standardisation bodies (IETF, ITU, ETSI) PTS'2001

  10. Network Services • Premium CBR for IP Telephony and Voice Trunking • very low delay and jitter, very low loss, hard bandwidth guarantee, small packets • Premium VBR for Video Streaming and Teleconferencing • low delay and jitter, low loss, bandwidth guarantee • Premium Multimedia for adaptive applications (TCP), e.g. ftp • bandwidth guarantee, moderate delay • Premium Mission Critical for interactive games, online banking • very low delay and loss, non-greedy flows and rather small packets • Standard • classical best effort traffic PTS'2001

  11. Description of the AQUILA testbed PTS'2001

  12. Example of AQUILA network topology Real network topology Lab testbed topology • 8 routers connected in the chain topology • Test traffic • Artificial flows submitted between PC1 and PC3 • Background traffic submitted on an ingress link to the network PTS'2001

  13. Warsaw - main trial site (Polish Telecom) • Special interest • real-time streaming applications (IP telephony, video conference) • non real-time streaming applications (e.g. Real System) • Trial scenarios • Network services (PCBR, PVBR,PMM,PMC) • QoS differentiation - mixture of network services • AC mechanisms PTS'2001

  14. Warsaw Testbed PTS'2001

  15. Planned Activities in IP QoS • Enhancement of the testbed • Real users • Inter-working with other networks (ATM) • Bringing AQUILA to the market • Co-operate with other IST projects in Internet area PTS'2001
