GÉANT Y3 Technical Roadmap

• Technology
• Network monitoring
• Services

3
Technology

• IPv6
• Optical developments
• Router testing

4
IPv6

• Continue to operate and extend IPv6 overlay
• add Hitachi router to form dual star topology
• add connection to Abilene
• Native IPv6 on GEANT, in dual stack fashion
• static routing by Autumn 2002, in co-operation
  with ARNES and REDIRIS
• dynamic routing by summer 2003, with network
  management tools
• NRENs will be encouraged to connect to and use
  pilot IPv6 service on GEANT
• From pilot to full service during Y4

5
Optical technology

• Benefits of and issues with 40Gbps (and beyond)
• Benefits of and issues with OOO
• Capacity management options
• packet based vs. circuit based
• granularity, scalability, reach, coverage
• Integrated IP/optical network control (G-MPLS)
• Feasibility of alternative service model with
  carriers (managed international fibre)
• Goal to be as good as we are with IP!

6
Router Testing

• Test programme with Alcatel (A7770)
• Interest in Avici TSR, Juniper T640 and others
• Lab testing followed by field trials

7
Network Monitoring

• Deployment of multi-domain infrastructure to
  monitor quality of the network
• basic network quality performance
• performance of different Classes of Service
• by summer 2003
• DANTE, PL, NO, UK, CH, IT, IE
• Guidelines for establishment of Performance
  Response Team
• by autumn 2003
• DANTE, IT, CH, UK, IE,CZ

8
Services

• Creation of multi-vendor testbed
• Enhance Multicast
• Enhance Premium IP
• Supporting projects

9
Multivendor testbed

• Services to be deployed on GEANT and NRENs of
  increasing complexity and number
• Need to perform thorough testing in a laboratory
  environment prior to trials on production
  networks
• For development of GEANT and NRENs
• Juniper, Cisco, Smartbits, Unix systems
  interconnected via a layer-2 VPN using MPLS/CCC
  techniques

10
Multicast enhancements

• Single Source Multicast
• simplifies interdomain operation of multicast
• increases reliability (spring 2003)
• Per-Group Monitoring (summer 2003)
• High capacity streams (100Mbps) (autumn 2003)
• IPv6 multicast
• DANTE, FR, CZ, DE, PL, UK

11
Premium IP enhancements

• Web-based user interface for collection of
  requests
• Automated resource allocation
• scheduled events
• one-time events
• Router configuration management
• summer 2003
• DANTE, GR, UK, PL

12
Supporting Projects

• More in depth understanding of user groups
  requirements
• high capacity BE,
• Premium IP,
• L2 VPN
• wavelengths
• 6NET, ATRIUM, JIVE, FAIN
• Engage in technical discussions with user groups
  and provide solutions
• DANTE, IT

13
Infrastructure to support projects

• Projects may require special treatment, which
  can be very difficult in our multi-domain env.
• GEANT and NRENs do not offer the same types of
  service (mpls/ccc, Premium, LBE)
• Access to GEANT for projects via NRENs
• Technical benefits if projects use different
  access
• Balance management of network (and recover costs)
  with promoting use of GEANT by projects

14
Project Access Options

• Dedicate a GE port for each NREN
• only possible where we have a PoP
• Use NREN backup port for projects access
• Projects supported through main access
• GEANT covers cost of GEANT access ports, NRENs
  cover own costs plus additional access circuit.

15
Access policies

• NREN authorises use of access to GEANT from
  projects
• Projects must not use the port in a
  production-like mode
• if they do, they must upgrade their access
• ports will be monitored, NRENPC will decide if
  utilisation is production-like.
• idea of 10 average, less than 50 peak

16
External projects

• Outside NREN community
• NRENPC must approve use of GEANT
• where possible use NREN projects access..
• .otherwise access charge to project
