GRID@LARGE Workshop, Lisbon, 29-30 August 2005

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



The GÉANT2 networkConnect. Communicate. Collaborate



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

Development programme

• Performance• Security• BW provision• Mobility

• Testbeds



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



Performance measurement Connect. Communicate. Collaborate



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,….



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



Mobility

• AAA

• Roaming

• Single sign on



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



GRID Projects

• LHC - EGEE• DEISA• Many more…



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



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



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
