NTP RGIG Patrik Fältström

Background SP – Technical Research Institute of Sweden Takes care of Swedish time – UTC(SP) Netnod Runs publicly available NTP servers Swedish Government Have talked in investigations about “traceable time” (spårbar tid) PTS and SAMFI Time and frequency is important

What has happened Netnod and PTS has been discussing time and frequency for years Netnod have run one pilot project 2012, financed by the TU-Foundation 2 nd project is now run by Netnod on request from, and financed by PTS In reality many organizations are involved, Internetkompetens, SP, SUNET, TU-Foundation

Timeline – Project start – Order hardware, contract consultants etc – Most hardware delivered 2015Q2 – Existing Rb clocks replaced with Cs 2015Q3 – Installation at all Netnod IX:es 2015Q4 – Software adjustment 2015Q4 – Service available

Services available Local time scale traceable to UTC(SP), exposed via NTP, IEEE 1588v2 and frequency Specifically 1pps and 5/10MHz from local time scale to NTP server and IEEE 1588v2 Grand Master Clock are to be correct NTP should respond over IPv4 and IPv6 with signed responses in up to 10Gbps IEEE 1588v2 available by the Grand Master Clock(s) Frequency in the form of IEEE 1588v2 on E1 interface (G.821) available by the Grand Master Clock(s)
