  1. GN2(and its support for GRIDs) GNEW 2004 Roberto Sabatino - DANTE Geneva, 15-16 March 2004

  2. The Challenge for GN2 • Make it even better than GN1/GEANT • end to end focus • Support GRIDs • network service • network performance

  3. Structure of GN2 • Integrated Infrastructure Initiative (III) • 4 years from ~September 2004 • Networking Activities (human, PR, task-forces etc) • NA1-NA7 • Service Activities (the network and its services) • SA1-SA4 • Joint Research Activities (service development) • JRA1-JRA5

  4. GN2: Network Architecture • A recurrent question: is an IP only network the best way to serve emerging requirements such as the ones from GRIDs ? • The answer appears to be NO. An architecture that scales better both economically and performance-wise is needed • A hybrid network, with switching and routing capabilities • How will we introduce that capability, and when ?

  5. GN2 cares about GRIDs • SA3 - end to end QoS - relationship with EGEE SA2 and JRA4 • JRA1 - network performance - strong relationship with EGEE JRA4 • JRA3 - BW allocation and reservation - strong relationship with EGEE JRA4 • JRA5 - will develop AAI

  6. SA3 - end to end QoS • PERT - Performance enhancement response team • network, systems and application level experts • proactive and reactive measures to improve e2e performance • End to end Provisioning of Premium IP • development and use of a Provisioning System used by a Provisioning Team • relationship with EGEE

  7. JRA3 BW allocation and reservation • Service: point to point (switched) connections operating at up to Gbps capacities (most likely GE), with a given QoS • Analysis/development of technologies to deliver the service • Development of middleware to request (a scheduled) service and to honour the request • Interaction with AAI

  8. GEANT NREN B Univ. AA Univ. BB NREN A Multidomain and multitechnology Resource Manager GEANT Resource Manager BB Resource Manager AA Resource Manager B Resource Manager A Host B Host A RSVP IP CoS MPLS ATM GMPLS Control Plane Data Plane

  9. Step by step • Start with focus on MPLS and TDM based techniques for provision of GE • single domain first, then multi-domain • “manual” setup/operation • interdomain operational procedures • Increase level of dynamism • develop Northbound BB interface • Increase level of network heterogeneity

  10. End to end ? • True end to end is always going to be hard • last mile domain outside scope of DANTE and NRENs • commitment to facilitate end to end • responsibility to manage and implement “edge to edge”

  11. Keeping up to date • JRA4 - technology and service testing TESTBED • Distributed across GN2, connects NREN testbeds • To evaluate emerging networking models: • fibre networks • lambda switching • Use them in GN2 when/if possible

  12. Thank You !
