Network Service Development (JRA4) Objectives JRA4 will provide common interfaces between Grid middleware and Network Resources Resources & Information Grid Consumers Middleware OGSA requirements: • Self contained Network Services JRA4 • Modular entity • IP Premium • MPLS paths & tunnels Network • Advertising Resources • Light paths Resources & Information • Publishing Information • Network Metrics • Performance <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 5
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 � SA1 EGEE • JRA4 Partners UCL � SA2 CNRS / UREC � DANTE � JRA4 DFN � GN1-2 GARR � GGF Others <EGEE Kick off, JRA4 Session, Cork> <19 Apr 2004> - 6
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

Bandwidth Allocation & Reservation • Any other Alternative ? • Whatever we do, it needs to be integrated in the Generic Middleware architecture.

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 � Grid Grid GOCs NOCs Users Middleware Operations NOC : Network Operation Center GOC : Grid Operation Center Performance Monitoring Service Network Common Interface (OGSA) (GEANT+NRENs) Domain_A Domain_B . . . .

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
