Abstract
A method and system for increasing the precision of time synchronization among a plurality of host nodes in a packet-switched network by reducing transmission delay variation in the network. Each host node is provided with a distinct set of transmission times selected from a global schedule in such a way as to avoid concurrent transmission of messages by the plurality of host nodes. The transmission times may be determined as offsets within a global hyperperiod, and each host node carries out transmissions according to predetermine offsets the respective host node. Transmissions according to offsets may be applied to real-time messages, including time-synchronization messages, hence yielding increase precision of synchronization.
