GÉANT Y3 Technical Roadmap
• Technology
• Network monitoring
• Services
Technology
• IPv6
• Optical developments
• Router testing
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
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!
Router Testing
• Test programme with Alcatel (A7770)
• Interest in Avici TSR, Juniper T640 and others
• Lab testing followed by field trials
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
Services
• Creation of multi-vendor testbed
• Enhance Multicast
• Enhance Premium IP
• Supporting projects
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
Multicast enhancements
• Single Source Multicast
• simplifies interdomain operation of multicast
• increases reliability (spring 2003)
• Per-Group Monitoring (summer 2003)
• High capacity streams (100+Mbps) (autumn 2003)
• IPv6 multicast
• DANTE, FR, CZ, DE, PL, UK
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
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
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
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.
Access policies
• NREN authorises use of access to GEANT from
projects
• Projects must not use the port in a “productionlike” 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
External projects
• Outside NREN community
• NRENPC must approve use of GEANT
• where possible use NREN projects access…..
• ….otherwise access charge to project
