Abstract
A timing source is provided for sending timing information via a packet network. The source comprises a clock for generating the timing information and a packet-forming section for forming a sequence of packets for transporting the timing information to a destination node. A time-stamping section inserts into each packet of the sequence a transmission time derived from the clock and acts as an output section for forwarding the packets to the network at the respective transmission times. In one mode, the packet forming section forms all of the packets of the sequence with the largest size which the packet network is capable of transporting. In another mode, the packets of the sequence have a distribution of sizes which may be fixed or which may vary in response to traffic conditions.
