Repartition of weighting factors between the port control and switches of a packet switching device

摘要

The arrangement has several line units, each consisting of a port controller for storing and arranging packets in queues and generating and altering weightings, and several switching units, each with a coupling matrix and an allocation unit for controlling the matrix. The port controllers each transmit an altered weighting selected from a table using a round-robin technique to the allocation unit. AN Independent claim is also included for the following: a port control method and a switching method for a packet switching arrangement.
