An accurate, NTP-based system is essential not only for individual users but also for local and national economies. It enables everything from air traffic control, bank transactions and computer log files to applications for legal, medical and manufacturing processes. In 2013, the Swedish Post and Telecom Authority (PTS) issued recommendations for making a more robust and reliable time distribution service in Sweden. When the PTS were looking for a trusted partner to design, implement and operate this service, they chose Netnod. With more than 20 years of experience at the core of the Internet, Netnod has the established expertise for providing critical infrastructure support, ranging from DNS services and root server operations to Internet exchange points and NTP distribution. During 2015, Netnod worked with the PTS and the SP National Laboratory to develop the infrastructure for a more robust, nationwide time distribution service. The service, operational since December 2015, includes: 4 distributed nodes at Internet exchange points in: Stockholm, Malmö-Copenhagen, Gothenburg, and Sundsvall local time scales traceable to UTC (SP) within ± 250 ns external monitoring for independent quality and performance assessment. high-performance NTP servers with anycast addresses using both IPv4 and IPv6 to mitigate Denial of Service (DoS) attacks and to simplify user configurations More information about the Swedish National Laboratory for Time and Frequency Facebook Twitter LinkedIn Email TAGS NTP NTP Network Time Protocol (NTP) Keeping Sweden in sync - NTP is the most commonly used protocol for synchronizing the time on computer systems.
