Abstract
A switch for use in a virtual communications system having multiple local area networks interconnected by multiple switches includes a first communications port connected to a network resource and a second communications port connected to other switches in the virtual communications system. A control console detects a communication from the resource to an addressee. The addressee is a member of a local area network within one or more virtual networks which exclude the network resource. The local area network is interconnected to the second communications port by another switch. The control console appends a privileged header to the communication which is detected by the other switch. Responsive to detection of the privileged header the other switch directs the communication to the local area network.
