NREN environment

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

4
Why possible now?

• Flexible/cheap services are emerging on the
  market
• NRENs can utilize dark-fibre and thus define
  networked 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

Possible NREN services

• Point to point services
• all service layers
• intra-ste (e.g. LAN interconnect)
• Inter-site (e.g. IP Transit, projects)
• Networked services
• all service layers
• local, regional and national (VPN)
• Speed 10/100 Mbit/s - 1/10 Gbit/s
• Physical path diversity
• Peerings with comparable services/capabilities
• national/international
• cross border services
• Commodity Internet

7
Service layers

• Layer A/B (ISO layer 0)
• dark fibre
• Layer C (ISO layer 1)
• lambdas/WDM, optical switching
• Layer D (ISO layer 2-2.5)
• framing (SDH/SONET, ethernet, GFP, MPLS)
• Layer E (ISO layer 3)
• IP layer

Naming of services

• CLnet4 lightpath deterministic like SDH/GFP
• Point to point connection like ethernet framed
• Lambda services
• most of the time SDH/GFP framing
• sometimes a pure optical path (no framing)
• Pure optical paths
• DWDM
• CWDM
• Dark fibre

10
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)

Initiatives in/around our region

• SEEFIRE project
• PIONEER (PSNC)
• Ideas for another project in middle Europe

• Conclusions

25
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 installation work
  can take very long periods of time to get. Up to
  6 months. Permission can also be denied
• Contract/SLA negotiations can take 12 months from
  start to finish
• Plan well in advance

• Conclusions

27
Conclusions (1/2)

• A proper established NREN organizational
  structure is important
• For interconnecting these NREN services it is
  essential to have good collaboration
• Network must be able to cater for present and
  future services evolving requirements
• So flexibility in capabilities/services is
  essential
• Well defined operational boundaries between
  capabilities (piloting) and services
  (pre-operations and operations).
• Bartering of connections between NRENs

28
Conclusions (2/2)

• Open issues
• how to do measurements?
• routing and firewall/security
• user empowered networking (CLnet4 UCLP)
• End to end concept is important and has to be
  part of vision
• Close cooperation with government to be part of
  their long term plans
• Try to get strategic/research/education reserve
  into governmental projects
• Acquire your fibre!!!
