ABSTRACT:
A network controller for dynamically rearranging a LAN to guarantee bandwidth required for multimedia communications comprises a switch for being connected to the transmit and receive ports of each LAN station and a switch controller. The switch comprises an internal switching fabric such that any receive port can be connected to any transmit port of any of the stations. The switch controller, which is connected to the primary LAN, controls the switch so that the LAN may be dynamically reconfigured when, for instance, a LAN node wishes to establish a private session with another LAN node. The request from the node to the controller is sent in a packet being passed around the primary ring. After the data transfer is complete between the two stations and they wish to re-enter the primary ring, one of the stations issues a request to the network controller to reconfigure the network. The request is made by applying a DC voltage to one of the node's receive or transmit line pairs. The network controller detects this signal with DC detection circuitry and reconfigures the network accordingly.
