Abstract
Hardware time stamping and synchronized data transmission disclosed. In a method, a reference time stamp and a local time stamp are obtained. A synchronization offset is prepared based on the local time stamp and the reference time stamp. Instructions are received to send a plurality of data units at a specified time. The plurality of data units are sent at the specified time based on referring to a local time obtained from a local clock and the synchronization offset to simultaneously send a packet storm comprising the plurality of data units. The method may be achieved by a network communications unit on a plurality of network cards included in a network testing system.
