Outline
  • NREN environment
  • Possible NREN services/capabilities
  • Examples of (inter)national networks
  • Experience with fibre
  • Conditions

3
NREN environment
  • Different type of provider than telco/ISP
  • Generally one user group and one AUP
  • Highly demanding and progressive users
  • Have opportunities for testing new ideas
  • Studying new technologies within its environment
  • NRENs are early adopters
  • Experience from earlier technologies
  • KISS Keep It Simple Stupid
  • Market development and stimulation

4
Why possible now?
  • Flexible/cheap services are emerging on the
    market
  • NRENs can utilize dark-fibre and thus define
    network services in its own pace
  • Electricity/gas/transport/oil/etc. companies
    could provide fibre
  • If no fibre available, services of telcos can be
    incorporated
  • A real demand is emerging from clients (e.g. LAN
    interconnect) and end-users (e.g. Grid projects)
  • Ethernet framing is emerging as a LAN-MAN-RAN-WAN
    technology

Outline
  • NREN environment
  • Possible NREN services/capabilities
  • Examples of (inter)national networks
  • Experience with fibre
  • Conditions

6
Possible NREN services
  • Speed 10/100, 1000 Mbit/s (ethernet framing)
  • IP transit connectivity (IPv4/IPv6,
    uni/multicast, commodity)
  • Intra-site point to point connections (e.g. LAN
    interconnect)
  • Inter-site point to point connections (e.g. IP
    transit, projects)
  • Coloured p2p connections
  • CWDM (MAN/RAN) unframed
  • DWDM (WAN) GFP framed
  • Dark fibre connections (MAN)
  • Cross border services
  • Physical diversity (if feasible)

Layer D (2-2.5)
Ether net

Layer C (1)
Telcos

Layer B (0)
p2p
Layer A (0)
8
Possible NREN capabilities
  • Testing new technologies in local, national and
    European scale
  • Getting multi domain experience for user
    empowered service provisioning
  • Procedural issues around such new capabilities
  • Close relation with other (comparable) projects
  • Close relation with carrier service providers and
    manufacturers (IP and optical USA and EU based)

9
Naming of services
  • CLnet4 lightpath deterministic like SDH/GFP
  • Point to point connection ethernet framing
  • Lambda services
  • most of the time SDH/GFP framing
  • sometimes a real lambda (no framing)
  • Optical network

  • NREN environment
  • Possible NREN services/capabilities
  • Examples of (inter)national networks
  • Experience with fibre
  • Conditions

23
Experience with fibre
  • Always get an OTDR trace from between each site.
    Saves time and money!!!
  • dB budget essential for calculations
  • Permits/permission to carry out civil work can
    take very long periods of time to get. Up to 6
    months. Permission can also be denied
  • Contract negotiations can take 12 months from
    start to finish
  • Plan well in advance

25
Conditions (1/2)
  • A proper established NREN organizational
    structure must be realized
  • For interconnecting these NREN services it is
    essential to have good collaboration
  • Well defined boundaries between piloting,
    pre-operations and operations of network
    services.
  • Network must be able to cater for present and
    future services.
  • So flexibility in capabilities/services is
    essential

26
Conditions (2/2)
  • Close cooperation with government to be part of
    their long term plans
  • Try to get strategic/research/education reserve
    into governmental projects
  • How to do measurements?
  • Routing and firewall/security issues have to be
    studied
  • User empowered networking is important step
