Packet switching device for packet data transport has coupling field provided by coupling matrices and switching controls connected in cascade

摘要

The packet switching device has a coupling field provided by a number of coupling matrices (6) and associated switching controls (7) connected in cascade, each switching control having an identification analyser for identifying an input port in a data packet route identification, an output assigner evaluating the route identification, a configuration unit for storing acceptable links between the input and output ports and an analyser allowing an adjusted route identification to be fed to a port control..
