Reduced broadcast algorithm for source routing

Source routing is an effective method for routing frames through high speed bridged LANs. The major disadvantage of the method is the high overheads associated with the route discovery procedure. A method is described for finding optimum routes that has minimum overheads associated with it. This is achieved with a simple address comparison in each bridge that results in a reduced load on the network and processing overheads in end stations compared with the existing source routing method.
