  1. Javier OrellanaEGEE-JRA4 Coordinator Grid Networking Workshop 2004 CERN 15-16March 2004 Network Services in EGEE EGEE is proposed as a project funded by the European Union under contract IST-2003-508833

  2. Outline • EGEE brief description • Network Resource Provision (SA2) • Network Services Development (JRA4) GNEW2004 – CERN 15-16March 2004

  3. EGEE Activity Areas • Services • Deliver “production level” grid services (manageable, robust, resilient to failure) • Middleware • Grid middleware re-engineering activity in support of the production services • Networking • Proactively market Grid services to new research communities in academia and industry • Provide necessary education GNEW2004 – CERN 15-16March 2004

  4. EGEE Activities Equivalent EDG Work Packages / Groups WP6 WP7 WP1-5 & 6 QAG Security Group WP7 WP12 WP11 WP11 WP8-10 ? • EGEE includes 11 activities • Services • SA1: Grid Operations, Support and Management • SA2: Network Resource Provision • Middleware (Joint Research) • JRA1: Middleware Engineering and Integration • JRA2: Quality Assurance • JRA3: Security • JRA4: Network Services Development • Networking • NA1:Management • NA2:Dissemination and Outreach • NA3: User Training and Education • NA4:Application Identification and Support • NA5:Policy and International Cooperation GNEW2004 – CERN 15-16March 2004

  5. Network Resource Provision (SA2) Objective Ensure EGEE can access the new network services provided by GEANT and the NRENs that will link: • Users • Resources • Operations NREN NREN • SA2 Partners • CNRS / UREC • RCC KI • GRNET EGEE(SA2) GEANT NREN GEANT High-speed pan-European backbone linking NRENs run by DANTE NRENs National Research and Educational Networks DANTE Not-for-profit company that manages GEANT GNEW2004 – CERN 15-16March 2004

  6. SA2 Tasks • Tasks • Definition of requirements • Specification of services • Definition of network access policies • Monitoring of service level provision • Outside of Scope • Provide connectivity or increase of bandwidth capacity to sites GNEW2004 – CERN 15-16March 2004

  7. Network Operation Center Grid Operation Center Modelling Operations: SA2 Approach • Definition of network services through standard processes: • Gather of Service Level Request (SLR) from end users and applications • Definition of Service Level Specifications (SLSs) by SA2, to be implemented by GEANT and the NRENs, in conjunction with JRA4 activity • Signature of Service Level Agreement (SLAs) between applications, SA2 and GEANT/NRENs • Study of Network Operation Centres (NOCs) procedures on GEANT and selected NRENS and incremental integration with EGEE Grid Operations Centers (GOCs). • Outside the EGEE scope to provide connections for any user or resource site • Sites must have adequate bandwidth & performance to join the production grid facility • Go beyond existing best effort IP service to meet the needs of a production level grid network GNEW2004 – CERN 15-16March 2004

  8. Network Service Development (JRA4) Objective JRA4 will provide common interfaces between Grid middleware and Network Resources Resources & Information Consumers Grid Middleware • OGSA requirements: • Self contained • Modular entity Network Services JRA4 • IP Premium • MPLS paths & tunnels • Light paths • Network Metrics • Performance Network Resources & Information • Advertising Resources • Publishing Information GNEW2004 – CERN 15-16March 2004

  9. GN1-2 GGF SA1 JRA4 SA2 Others JRA4 Tasks and Context • Main sub-activities: • Bandwidth Allocation and Reservation • Network Performance Monitoring and Diagnostic tools • and, also IPv6 uptake • DANTE already deploying basic infrastructure in GEANT (current GN1 and the coming GN2 projects): • Introduction of Layer 3 differentiated services (Premium, BE, LBE) • Instrumentation for network measurement • JRA4 Partners • UCL • CNRS / UREC • DANTE • DFN • GARR EGEE GNEW2004 – CERN 15-16March 2004

  10. BB Bandwidth Broker Traffic flows Signalling between BB Provisioning devices C A B BB BB BB BB JRA4 : Bandwidth Allocation & Reservation • Allocating network resources (IP Premium, Paths, etc… ) : • immediate • advance • Two features: • multiple domains and, • Authorization and Authentication for end users ie.: One flow from A to C Two flows from A to B NREN C GEANT NREN B NREN A GNEW2004 – CERN 15-16March 2004

  11. Grid Middleware Grid Users JRA4 :Network Performance Monitoring • Grid Performance closely linked to Network Performance • Network Performance?, what for? : • Problem diagnostic and rectification • Facilitate resources allocation • Performance monitoring and SLA adherence GOCs NOCs Operations NOC: Network Operation Center GOC: Grid Operation Center Performance Monitoring Service Network (GEANT+NRENs) Common Interface (OGSA) Domain_A Domain_B . . . . Domain_X GNEW2004 – CERN 15-16March 2004

  12. JRA4 : IPv6 uptake Study of the advantages of using IPv6 in Grid context: • DANTE deploying IPv6 (already started) • IPv6 is effective if deployed in all domains The report will cover: • Study of features of IPv6, highlighting the ones of interest for Grids • Availability of IPv6 in NRENs and access networks • EGEE internal awareness of IPv6 Also: • Collaboration with 6NET. Letter from EGEE already sent • Possibility of building a testbed, needs to be agreed GNEW2004 – CERN 15-16March 2004

  13. JRA4 : Deliverables • Bandwidth Allocation & Reservation: • DJRA4.1 (M6, Sep/04): Specification of Interfaces (network control plane & global resource reservation middleware) • DJRA4.4 (M21, Dec/05): Implementation of pilot • DJRA4.6 (M24, Mar/06): Final Report • Network Performance Monitoring & Diagnostic tools: • DJRA4.2 (M9, Dec/04): Definition of standardised network measurement query/response interfaces • DJRA4.5 (M21, Dec/05): Service to supply network perf. Information to resource brokering • DJRA4.7 (M24, Mar/06): Final Report • IPv6: • DJRA4.3 (M18, Sep/05): Final Report GNEW2004 – CERN 15-16March 2004

  14. Further Information… • EGEE starts officially on the 1st April 2004 • Kick-off Meeting : Cork (Ireland) from Sunday 18th/Apr to Thursday 22nd/Apr http://www.eu-egee.org http://egee-jra4.web.cern.ch/EGEE-JRA4 GNEW2004 – CERN 15-16March 2004
