Abstract:
A method of synchronising first and second clocks coupled respectively to ingress and egress interfaces 6,7 of a packet network 1, the method comprising calculating a minimum packet Transit Time over the network 1 in each of successive time intervals, and varying the frequency of the second clock so as to track variations in the minimum packet Transit Time.
