ADD AND DROP ELEMENTS FOR NTP ON-PATH-SUPPORT AND METHOD FOR INTER-OPERATING BETWEEN NTP AND IEEE-1588 PROTOCOL DOMAINS

摘要

A method and system for providing add/drop elements at boundaries between NTP domains and IEEE-1588 domains. The add/drop elements encapsulate incoming NTP messaging time-stamps within 1588 messages, and update the NTP time-stamp information upon entry/exit from the IEEE-1588 domain. The add/drop element system is particularly useful for overcoming the requirements for extra time gateways in order to achieve timing parity between IETF NTP and IEEE1588V2.
