The Technological Landscape of GÉANT2

• Roberto Sabatino, DANTE
• Roberto.Sabatino_at_dante.org.uk

2
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 network
4
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

9
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

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,.

12
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

13
Mobility

• AAA
• Roaming
• Single sign on

14
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

15
GRID Projects

• LHC - EGEE
• DEISA
• Many more

16
EGEE JRA4

• JRA4 Network Services Development activity
  within EGEE
• Understand GRID applications 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

17
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

18
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 DANTEs Perfmonit
• Focus on Security upgrade DANTE Perfmonit tool
  to use certificates issued by EU Grid PMA
• EGEE plans to use GEANT2 JRA1s prototype results
  for next phase
• GEANT2 JRA1 plans to provide capacity and link
  utilization by September 2005
