1 Nordic Infrastructure for Research & Education The NORDUnet Next Generation Network Building the future (Nordic) network together October 11, 2018 Jørgen Qvist, NORDUnet

2 The Nordic NREN Networks Lars Fischer, NORDUnet EISCAT-3D Stakeholder Meeting 17 September

3 Background - Technology Coherent Disaggregation Open Line System (OLS) Control / management Data Centre Interconnect (DCI) Transponders DCI OLS

4 Backgound - How we work. Collaboration on shared infrastructure Experience Mutations ie. NORDUnet / SURFnet Nordic cross border fiber links Operations of shared infrastructure Non-issue Federated operations model alá ANA

5 Background - Premise 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 Approach Gather information from NREN s and NORDUnet 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..

7 Why a new network? Today s centralization trends and the ever growing 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.

8 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 re-use of existing optical platform OLS

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

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 Current NORDUnet topology

14 Current NORDUnet topology SPOFs

15 Architecture and topology options 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

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

17 Nordic Infrastructure for Research & Education Reference Architecture and Objectives Red = New infrastructure Yellow = Existing Nordic NREN network Green = Existing NREN Network (excl. GÉANT) Blue = sub-sea-cable capacity 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

18 Nordic Infrastructure for Research & Education Reference Architecture and DK Red = New infrastructure Yellow = Existing Nordic NREN network Green = Existing NREN Network (excl. GÉANT) Blue = sub-sea-cable capacity 1. Kristiansand - Esbjerg 2. Esbjerg Emshaven 3. Esbjerg(Kolding) - Hamburg 4. Copenhagen Malmø Rønne - Berlin

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

20 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
