Abstract:
A packet switching device is disclosed. The packet switching device includes at least one line card with a port control for storage and arrangement of packets in output queues and for generating status information of the output queue, and at least one switch card consisting of a crosspoint matrix and an arbiter to control the crosspoint matrix. The port control distributes the status information over several arbiters. Each responding arbiter is provided to cyclically receive a respective part of the status information from the port control.
