ABSTRACT:
A computing system, having an input/output bus for communicating data thereon, is connected to a network by a pair of network controller devices. Each of the network controller devices, in turn, connect to a corresponding one of a pair of multi-ported network repeater elements which are, in turn, connected to one another by a pair of network links. At least one workstation is connected to each of the network repeaters. One of the network controllers is initially selected as a primary data communicating path from the computing system to the network. The network controllers periodically transmit messages to one another, and if receipt of those messages by the primary network controller is noted, the selection of the primary controller will be switched to the other.
