Packet Switching Device and Local Communication Network With Such a Packet Switching Device

摘要

A packet switching device comprises a network interface configured to send and receive data packets via a communication network, a plurality of string interfaces configured to transmit and receive data packets to/from a plurality of participants and a switching unit connected to the network interface and to the plurality of string interfaces. The a switching unit comprises a control unit configured to control a data throughput. The control unit comprises an interface association table which determines that data packets received via the network interface are mandatorily outputted via the string interfaces and the data packets received via the string interfaces are mandatorily outputted via the network interface.
