Below the Sky: Building Resilient Terrestrial Time Networks for Europe: BoF
- Raimena Veisllari (Sikt)
- Domenico (Dom) Vicinanza (GÉANT)
- Guy Roberts (GÉANT)
Description
As European NRENs come under pressure to meet the European Commission’s objectives of sovereign infrastructures for critical services, the distribution of high-accuracy Time and Frequency (T&F) has become a strategic priority. Following the release of the GN5-2 Whitepaper on Long-haul White Rabbit (WR) Time Distribution, this BoF session brings together the community and infrastructure partners to discuss the technical and economic roadmap for terrestrial time services in the R&E environment.
Global Navigation Satellite Systems (GNSS) are increasingly vulnerable to jamming and spoofing. This session will explore how the GÉANT community can leverage existing "legacy" DWDM fibre infrastructure to distribute a sub-nanosecond "ground truth" using White Rabbit technology, serving as a sovereign, resilient backup to satellite-based time.
BoF Agenda
- Intro (10 mins): Summary of the whitepaper's key performance results and associated recommendations.
- Industry/NREN Q&A (30 mins): Three 10-minute lightening talks by NREN/NMI engineers regarding network deployments and/or equipment vendors regarding WRS for time services.
- Roundtable Discussions (40 mins): Participants will be grouped by "deployment challenge" (e.g., Optical Layer vs. Economic/OAM) to identify common pain points.
- Next Steps (10 mins): Round table rapporteurs to summarize what NRENs would like to request from the WR Collaboration and from the GÉANT SIG-TFN.
