3. Technology Background 100G coherent Disaggregation
Open Line System (OLS)
Control / management
Data Center Interconnect (DCI) Transponders
DCI
OLS

4. Collaboration on shared infrastructure
Background
Collaboration on shared infrastructure
Experience
Mutations ie. NORDUnet / SURFnet
Operations of shared infrastructure
Non-issue
Federated operations model alá ANA

5. Basic alignment before start
Background
Basic alignment before start
We will share infrastructure !
Don’t ask what NORDUnet can do for you, ask yourselves what you can do for NORDUnet

6. Background
Today´s centralization trends and the emerging use of cloud services demand more of the network infrastructure than ever before. Therefore having a network that is designed for 100% availability is a must.
MS office, google doc s in the cloud, LMS systems in the cloud web conf and other media services are centralised,,

7. Gather information from NREN’s and NDN board
Approach
Gather information from NREN’s and NDN board
Network working group of Nordic NREN CTO’s and senior techs
Collaboration on development of the Network objectives and cost sharing model
Iterative process, constantly aligning the progress with stakeholders..

8. Initial reuse of existing optical platform
Approach
Cost sharing model
Nordic NREN’s will provide NORDUnet with the needed spectrum in their respective networks
NORDUnet will cover the cost of getting access to the spectrum (incremental cost)
Initial reuse of existing optical platform
By reusing the OLS part of the existing Ciena platform that is getting freed up in the Nordics we a can lower the initial investment

9. NEXTgen Network Objectives
Accommodate ladder architecture
Adding redundancy out of Norway as per Nkom report recommendations
Adding redundancy as per N+2(3) desire
Have topology protect against major city or regional infrastructure outages
Have one link from each NREN to Europe not touching any other Nordic NREN
Using NREN spectrum where technically possible
Redundancy to support ”100% availability” starts with the number 3
Ladder is having large north south pipes and build ladders –east-west to create mesh and avoid network segmentation
Regional, cyber attacks or other outages to ie. Power infrastructure

10. NEXTgen Network Objectives
NDN fiber only where necessary, but keeping an EU footprint that still makes NDN an attractive partner for NREN’s and commercial operators
Take in to account the requirements for any known major infrastructure projects in the Nordics ie.
ESS - European Spallation Source, Lund and Copenhagen
EISCAT_3D - Incoherent Scatter Radar facility, that will be located in Finland, Norway and Sweden, way up north… 
Be affordable = lower overall cost than the current generation network

11. NEXTgen Operational Objectives
Create sufficient redundancy to lower the operational cost by;
Minimising the need for 24/7 support in the classic sense
Lowering the on site support levels and spare parts to NBD (Next Business Day)
Establish a federated operations model

12. Architecture and design
Support the various redundancy objectives
Initial design to deliver 4 x 50GHz spectrum = 400GBps on all major stretches
The Network must be affordable

13. Architecture and design options
Basic as is Nordic core using NREN spectrum
Add a Baltic route
Add a direct Norway-Denmark and vest Jutland route not touching Oslo
Add a route Esbjerg-Hamburg
Add a route Esbjerg-Amsterdam (Cobra cable)
Add a route to support ESS and SUNET Copenhagen-Lund-via Bornholm to Germany
Add a route Finland-Sweden via Åland

14. Architecture and design options
Add a route Gothenburg - Frederikshavn
Add another CBF Ladder Finland(Vaasa)-Sweden (Umeå)-Norway (Trondheim) to protect against network segmentation
Add………..
The Network must be affordable

15. Reference Architecture and Objectives
Accommodate ladder architecture ✔︎
Adding redundancy out of Norway as per Nkom report recommendations ✔︎
Adding redundancy as per N+2(3) desire ✔︎
Have topology protect against major city or regional infrastructure outages. ✔︎ Dependency on Stockholm, Copenhagen and Hamburg regional areas removed
Have one link from each NREN to Europe not touching any other Nordic NREN ✔︎
Using NREN spectrum where technically possible ✔︎
keeping an EU footprint that still makes NDN an attractive partner for NREN’s and commercial operators Having NORDUnet connectivity
Amsterdam – London
London – Frankfurt
Frankfurt - Berlin
And at least one route out of Scandinavia not touching Hamburg
Yellow = Nordic NREN Spectrum
Lighblue commercial capacity
Green existing NREN networks willing to share spectrum
Red new routes that need to be analysed and realised in the most sensible way. There are other options but this is the preferred Arcitecture that hopefullly will turn out to be affordabæe

16. Reference architecture agreed ︎✓ Cost sharing model agreed ✓
Status
Reference architecture agreed ︎✓
Cost sharing model agreed ✓
Operational objectives agreed ✓
Board approval for migration to spectrum on exiting Nordic NREN infrastructures agreed ✓
High level plan for implementation and transition to new architecture in place ✓

17. Next Steps
Further investigate Denmark – Norway, Nordic to Europe and inter Europe fiber and connectivity options.
Investigate and analyse optical equipment options including joint procurement
Making sure that the Network remain affordable during the transition process and beyond…..
Secure alignment with the GÉANT Next Generation network and fiber foot print
Alignment ie. Not having 4 routes from London to mainland Europe
