GÉANT2 focus
Connect. Communicate. Collaborate
• 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 importance of
Ethernet
Connect. Communicate. Collaborate
• GE and 10GE with guaranteed quality
• 10 GE as service specification and access to GE service
• Challenge to GÉANT2, NRENs and equipment vendors

Performance enhancement
Connect. Communicate. Collaborate
• 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

Service provision
Connect. Communicate. Collaborate
• 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,….
GRID@LARGE Workshop, Lisbon, 29-30 August 2005
Security
Connect. Communicate. Collaborate
• 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
Connect. Communicate. Collaborate
• 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

• LHC - EGEE
• DEISA
• Many more…
GRID@LARGE Workshop, Lisbon, 29-30 August 2005
EGEE JRA4
Connect. Communicate. Collaborate
• 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
GRID@LARGE Workshop, Lisbon, 29-30 August 2005
Bandwidth Allocation and
Reservation
Connect. Communicate. Collaborate
• 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
GRID@LARGE Workshop, Lisbon, 29-30 August 2005
Network Performance
Monitoring
Connect. Communicate. Collaborate
• 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
