Abstract

First, a packet may be received and a timestamp value may be placed on the packet. The timestamp value may comprise a place time value comprising a time when the timestamp was placed on the packet plus a delay time value comprising an estimated time delay between when the timestamp was placed on the packet and when the packet leaves a port exit. Next, the packet may be sent to a first in first out (FIFO) memory. The packet may then be sent from the FIFO memory out the port exit.
