Towards a National Dark Fibre Infrastructure Service
• Statement of need submitted to EPSRC ICT Mid-Range Facilities Consultation to provide a dark fibre networking facility accessible to the UK ICT research community- 2009
• The panel ranked it top in priority- 2009
• Progress in the tender delayed due to uncertainty on responsibility for funding of underlying dark fibre
• Janet confirmed support for future leasing of fibre in support of NDFIS
• EPSRC tender issued December 2012, closed February 2013
• Consortium comprising UCL, Bristol, Cambridge,Janet and Southampton selected as preferred tenderer, May 2013
• Contract negotiations to start, with planned start of service, September 2013

Conclusion
• The future internet will depend on a transmission infrastructure of greatly increased capacity and flexibility
• The Aurora dark fibre network has enabled experimentation at the physical layer to study new devices, sub-systems and transmission formats to deliver the capacity and flexibility required
• The NDFIS, a collaboration between Janet and Universities with strong research records in optical communications and networking, will provide a platform for the development of software defined networks for the future internet
• NDFIS will have novel capabilities for software defined transmission path parameters and physical and logical connectivity
• NDFIS will also have strong connectivity to other experimental networks worldwide for collaborative research
