ABSTRACT OF THE DISCLOSURE In a packet-switched communications network, the variable component of a delay suffered by the first packet of a message is estimated at a receiving node and compared with a desired minimum delay selected to be just sufficiently large to encompass most expected delay variations, the result of the comparison being used to set a clock controlling reconstitution of the received signal so as to subject the received packets to a delay approximating to but not less than the desired delay. The estimate of the variable delay component is successively updated during reception of further packets to converge on the actual value of that component, the clock at the receiving node being updated accordingly to bring it into synchronization with a transmitter clock, sub- ject to a lag equal to the desired minimum delay.
