  2. Contents • EGEE brief description • Network Services Development (JRA4) • Tasks • Bandwidth Allocation and Reservation • Network Performance Monitoring • IPv6 uptake <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 2

  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 <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 3

  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 <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 4

  5. Network Service Development (JRA4) Objectives 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 <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 5

  6. GN1-2 GGF SA1 JRA4 SA2 EGEE 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 Kick off, JRA4 Session, Cork> <19 Apr 2004> - 6

  7. Bandwidth Allocation & Reservation • Network Resources: • Layer 3 - diffserv based traffic: IP Premium, Scavenger, … • Layer 2 : VLAN, MPLS • Layer 1 : lightpaths • Allocating network resources : • immediate • advance • Features: • Multiple domains • Users as part of Virtual Organizations • Authorization, Authentication and Accounting of end users • Policy derived from SLA (input from SA2 – Geant, NRENs) <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 7

  10. Bandwidth Allocation & Reservation • Any other Alternative ? • Whatever we do, it needs to be integrated in the Generic Middleware architecture. Consumer (User Application) Grid Middleware Disk Service CPU Service Network Service Network (GEANT+NRENs) Common Interface (OGSA) Domain_A Domain_B Domain_X <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 10

  11. Grid Middleware Grid Users 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 . . . .

OWD from point A to B ? • PMSx and DMx • Are independent implementation for the measurements • Features • Multiple domains, AAA, OGSA/OGSI We DON’T yet We got that already NREN A GEANT NREN B OWD=OWD1+OWD2+OWD3 <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 12

  15. 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 • Possibility of building a testbed, needs to be agreed <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 15
