Transfer of a synchronization message through a packet radio network |
摘要 |
<p>It is disclosed a method for transferring a synchronization message from a master node to a slave node through a packet-switched network. The method comprises the steps of: providing a reference clock signal to an ingress node and to an egress node of the packet-switched network; at the ingress node, receiving the synchronization message from the master node, generating an ingress timestamp based on the reference clock signal, and sending the synchronization message with the ingress timestamp to the egress node; and at the egress node, receiving the synchronization message and the ingress timestamp, generating an egress timestamp based on the reference clock signal, computing a transit time as a difference between the egress timestamp and the ingress timestamp and sending the synchronization message and the transit time to the slave node.</p> |
