The Technological Landscape of GÉANT2

1. The Technological Landscape of GÉANT2 Roberto Sabatino, DANTE Roberto.Sabatino@dante.org.uk

2. GÉANT2 focus • Make large amounts of capacity accessible( technically, economically) to users • taking network services a step further: • Ethernet (GE and 10GE), as service and as access technology • Performance (monitoring and enhancement) • Security • Mobility

3. Connect. Communicate. Collaborate The GÉANT2 network

4. The importance of Ethernet • GE and 10GE with guaranteed quality • 10 GE as service specification and access to GE service • Challenge to GÉANT2, NRENs and equipment vendors

5. Connect. Communicate. Collaborate The multidomain challenge for GE NREN-A NREN-B GEANT2 STM-64 GE 10 GE GE 10 GE STM-64

6. Connect. Communicate. Collaborate The multidomain challenge for 10 GE NREN-A GÉANT2 NREN-B 10 GE 10 GE 10 GE STM-64 NREN

7. Connect. Communicate. Collaborate GÉANT2 PoP example

8. Development programme • Performance • Security • BW provision • Mobility • Testbeds

9. Performance enhancement • A dual development program: • Help end users make the most of the network, via the PERT (Performance Enhancement Response Team) • Relies on multi-disciplinary experts • human-on-the job at all times (the case manager) • Knowledge-base and trouble tickets • Provide detailed, end to end performance measurement data • Measurement probes scattered throughout the network • Multidomain operation

10. Connect. Communicate. Collaborate Performance measurement

11. Service provision • Automate provision of service • For existing services (Premium IP) • Available single domain, in progress for multidomain • For new services (point to point 10/GE) • A key development activity for GÉANT2 • Start with a static single domain approach • Target dynamic, multidomain approach • G-MPLS, UCLP,….

12. Security • Strengthen security of network elements and services • Tools for anomaly detection and network forensics • Strengthen operational co-ordination and co-operation between GN2 partners for incident handling and resolution

13. Mobility • AAA • Roaming • Single sign on

14. Conclusions to network • The investment in dark fibre is the enabler for access to and management of large amounts of capacity • The mixed (routed + switched) network architecture is the enabler for service provision • The development programme is focussed on enhancing the traditional network services

15. GRID Projects • LHC - EGEE • DEISA • Many more…

16. EGEE JRA4 • JRA4: Network Services Development activity within EGEE • Understand GRID application’s network requirements • Established a working relationship between GRID and Networking communities • Feedback to Global Grid Forum (GGF) Network Measurement Working Group (NMWG) • JRA4 has three sub-activities • Bandwidth Allocation and Reservation (BAR) • Network Performance Monitoring (NPM) • IPv6 Uptake

17. Bandwidth Allocation and Reservation • Analysis of state-of-the-art provisioning mechanisms • Specification of a generic interface for requesting (current and future) network services • Define a multi-phased service provisioning model • Collaborate on an operational model for day-to-day operations and troubleshooting • Prototype BAR and Network provisioning web service • Investigate last mile issues and practical service usability

18. Network Performance Monitoring • Identify network metrics of interest to the Grid community for monitoring and troubleshooting purposes • Implement GGF NMWG XML Schemas to retrieve network metrics • Collaborate in various prototypes developed by JRA4 NPM Group • Focus on interfaces and technology - Provided One Way Delay Data through DANTE’s Perfmonit • Focus on Security – upgrade DANTE Perfmonit tool to use certificates issued by EU Grid PMA • EGEE plans to use GEANT2 JRA1’s prototype results for next phase • GEANT2 JRA1 plans to provide capacity and link utilization by September 2005
