Abstract
The present disclosure provides Network Element (NE) clock synchronization using Optical Transport Network (OTN) delay measurement systems and methods such as described in ITU-T G.709 (December 2009) 'Interfaces for the Optical Transport Network (OTN)' and G.798 (October 2010) 'Characteristics of optical transport network hierarchy equipment functional blocks'. OTN provides a Delay Measurement (DM) function to measure fiber path latency between two network elements to within microsecond accuracy. The convergence of packet switching and OTN transport into the same network element allows the sharing of this information between the two applications. The OTN delay measurement value can be used to synchronize two network element clocks to within microsecond accuracy without the need for a costly GPS synchronization solution or reduced accuracy NTP solutions.
