CAST Releases Tech Bulletin #001
< All News
CAST has released its first Technical Bulletin, highlighting observations on network visibility through precision time protocol (PTP) performance metrics. This is the first of many Technical Bulletins intended to demystify alternative timing and synchronization, PTP, and their implementation within the power grid.
This CAST technical bulletin highlights the effects of network path routing automation on time synchronization precision, network performance visibility through synchronization data. Utilizing PTP over DOE’s Energy Sciences Network (ESnet), we show that as ESnet reroutes network traffic to maintain/improve overall network latency can result in significant inaccuracies for time synchronization between network devices.
