Versatile source port enforcement for data networks

摘要

A communication switch comprises a plurality of ports and a processing unit configured to identify source ports and destination ports from the plurality of ports on a per virtual link basis. Each virtual link comprises one or more source ports via which frames are received from one or more source nodes and one or more destination ports via which received frames are forwarded to one or more destination nodes. For at least one virtual link, the processing unit is configured to accept more than one of the plurality of ports as source ports.

1. An Avionics Full-Duplex Switched Ethernet (AFDX) compatible communication switch comprising:
a plurality of ports; and a processing unit configured to identify source ports and destination ports from the plurality of ports on a per AFDX virtual link basis, wherein an AFDX virtual link is a unidirectional logic path that comprises one source port via which frames are received from one source node and one or more destination ports via which received frames are forwarded to one or more destination nodes; and wherein the processing unit is configured to accept at least one AFDX virtual link having more than one simultaneously active source port as a valid virtual link; wherein the received frames of each respective virtual link use the same respective multicast destination address.
