Life in a small NREN

Facts and figures

Signed EU structural grants 2016 - 2019:

0,8M social fund for service development

4,3M ERDF for national infrastructure

770 km own DF backbone, DWDM, 10G Leased DF CBF connection to Poland

50-site regional distribution network

20G GEANT core (LT-PL over the CBF)

Peerings over the CBF 876 organizations, including 585 schools

Network services: L0-L1 – only for advanced users (universities) L2-L3 – wide variety Network as a service – starting Usual pack of other services: Federation, T&I, Security, Clouds

241 km

171 km

99 km

146 km

Five years and beyond

Metro – fun part Short distances (10s of kilometers) Lots of locations connected over the distribution nodes

„Natural growth“ topology v.s. orderly network environment

New generation „virtual“ network

Concentrating on the backbone leaves metropolitan networks neglected

Five years and beyond

Easy bits • DF connectivity to the Observatory

• 10G connectivity to regional colleges

• Top up DWDM :

• 40 lambdas, ½ of 50GHz grid

• Some optical switching (non-CDC)

• Support for aliens and spectrum sharing

• 10G operational, 100G-ready

• Optical encryption • Upgrade routing platform

Local collaboration with the state enterprise „Infostruktura“ since 2010

Proven as efficient, will change more into client-provider relationship

Collaborations

International CBF opened the road for international collaboration

Currently operates 5 lambdas: (2xGEANT, Peerings, Experimental, and Time)

Some unanswered questions:

How to couple DWDM system

Who will operate the infrastructure

Who will provide services

What will the GEANT network be

What uses will be eligible

Conclusions

NREN perspective

1. Own infrastructure – lifeline in the uncertain times

2. DF deployment enables rapid advance, but not as rapid as sometimes required

3. Cross-border fibre connections enable closer collaboration with the neighbours

4. GEANT connectivity remains essential tool for the R&E
