The new “enhanced” primary reference time clock (PRTC) recommendation from the International Telecommunication Union (ITU), G.8272.1, looks set to be one of this year’s key innovations in the world of network synchronization. Aimed at producing the levels of accuracy necessary for 5G, enhanced PRTCs (ePRTCs) go far beyond the current technology. While the time output of today’s PRTCs should be accurate to within 100ns of Coordinated Universal Time (UTC), this new generation of clocks promises to deliver time to within just 30ns. ePRTCs also offer a greater level of reliability – unlike current PRTC technology, which has no holdover specifications, the emerging enhanced clocks are able to hold time accurately for 14 days, ensuring time service performance during GNSS outages ...

Beginning a post on cyber security with the observation that the threat being discussed is frightening is a bit redundant. They all are frightening. Very often, today’s threats are more dangerous because they are a mix of multiple things that, when combined, are more potent than the sum of their parts. In this case, four elements are present: botnets, DDoS attacks, the internet of things (IoT) and connected consumer electronics equipment. Put together, these inexpensive ingredients are enough to threaten the internet …
