Abstract
The variable latency associated with standard network forwarding devices is eliminated by forwarding timing packets through a network forwarding device with a constant delay. The network forwarding device of the invention time stamps timing packets that are received by the input ports with a predefined future time, and then outputs the timing packets from the output ports at the predefined time so that the transmission delay through the network forwarding device is the same from any port to any other port.
