Packet exchange device with coupling field has each exchange control for each coupling matrix providing feedback of results to preceding exchange control

摘要

The packet exchange device has a coupling field provided by a number of coupling matrices and associated exchange controls (7), connected in a matrix or a cascade, each having an identification analyzer for identifying an input port in a packet route identfication and storing the couplings between input ports and output ports and a result analyzer for informing the identification analyzer of the acceptable couplings. Each exchange control provides feedback of the results to the preceding exchange control.
