A method for performing a load flow test among a number of IEEE 1394 controllers is provided. The solution described herein provides techniques in the areas of proxy caching, protocol acceleration, domain name resolution acceleration as well as compression improvements. The first branch generates a first digital output for the zone addressing circuit when coupled to the common branch, and the second branch generates a second digital output for the zone addressing circuit when coupled to the common branch. For example, the actual address location of the media database is hidden from content recipients while its address directory is periodically change making past addresses obsolete. This reliably ensures that a terminal will not transmit and receive data simultaneously. The structural members have their compressive loading axes offset from their load central longitudinal axes.
