Abstract
A method for substantially preventing routing deadlocks and reliably routing service messages in a network comprised of successive stages of cross-point switches which collectively interconnect a plurality of nodes external to the network, wherein at least one service message is carried between one of the nodes and one of the cross-point switches over a route through the network, including the steps of defining a plurality of routes through the network such that at least one service message can be carried from individual nodes within the plurality of nodes over different corresponding ones of the routes to every cross-point switch within the network, wherein each of the defined routes extends over at least one link; duplicating a message to be routed through the network; and imposing routing restrictions on at least one of the cross-point switches in the network.
