DELIVERING DATA PACKETS IN AN ELECTRONIC INTERCONNECT

摘要

A system and method for delivering data packets (612) in an electronic interconnect (110) comprises a talker device (114) that transmits one or more data packets (612) over a transmission path to a listener device (150) through one or more bus bridges (126, 134, 142) that each couple adjacent busses in the electronic interconnect (110). Each data packet (612) includes a time stamp (620) that indicates when the corresponding data packet (612) is scheduled for presentation to the listener device (150). An initial bus bridge preferably creates a marker packet (712) that is propagated through the transmission path to record delay information corresponding to delay elements such as the intervening bus bridges. A final bus bridge (142) may then utilize the delay information from the marker packet (712) to update the time stamps (620) of the data packets (612) to thereby incorporate the total propagation delay of the transmission path.
