Abstract

Systems and methods are disclosed for utilizing large packet sizes to reduce unpredictable network delay variations in delivering timing packets across networks for use with respect to network timing protocols. By increasing the size of the timing packets, the disclosed embodiments reduce or eliminate the blocking effect caused by size differences between timing packets and relatively large packets carried through a packet network. By reducing or eliminating this blocking effect, the disclosed embodiments provide significant advantages in reducing the complexity of implementing robust timing protocols for handling unpredictable delays in the communication of timing packets. The size of timing packets can be increased, for example, by adding fill data to timing data to form large timing packets. A variety of large packet sizes can be used for the timing packets, and timing packets can preferably be made to be equal to the maximum transmission unit (MTU) for the network.
