Abstract

In a (e.g., ethernet-based PTP) time-distribution system, time receivers unicast (rather than multicast) delay-request messages and time transmitters unicast (rather than multicast) corresponding delay-response messages. An intervening transparent clock maintains a mapping table containing entries that map appropriate (PTP) port IDs to corresponding media access control (MAC) addresses that enable the transparent clock to forward the unicast delay-response messages towards the appropriate time receivers. As such, the volume of messages and the burden on transparent clocks to handle superfluous messages in such systems are reduced.
