The frequency of a local clock (30) of a local data processor 4 is synchronised to the frequency of a reference clock (10) of a source data processor (2). Both processors (2 and 4) are coupled to a coupled to an asynchronous switched network (6). The method of synchronising comprises sending, to the local data processor (4) from the source data processor (2), timing packets each including at least the destination address of the local processor and a field containing reference clock data indicating the time the packet was launched onto the network and controlling the frequency of the local clock (30) in dependence on the reference clock data. <IMAGE> |
