摘要： The present invention pertains to a nonblocking broadcast switching network. The network comprises an input stage. The input stage has N.sub.1 or n.sub.1 r.sub.1 input ports and r.sub.1 switches, where n.sub.1 .gtoreq.2 and r.sub.1 .gtoreq.1 and are integers. The network is also comprised of an output stage. The output stage has N.sub.2 or n.sub.2 r.sub.2 output ports and r.sub.2 switches, where n.sub.2 .gtoreq.2 and r.sub.1 .gtoreq.1 and are integers. There is also a middle stage. The middle stage has m switches where m is an integer and, where ##EQU1## The m switches are in communication with the r.sub.1 switches and r.sub.2 switches. The middle stage of m switches has L inputs, where L.gtoreq.r.sub.1 and is an integer, and J outputs, where J.gtoreq.r.sub.2 and is an integer, x or fewer of the m switches, where 1.gtoreq.x.gtoreq.min{n.sub.2 -1, r.sub.2 } and is an integer, always available to form a connection between an idle input port and a plurality of idle output ports, but no output port is connected to more than 1 input port. In a preferred embodiment, the controller is comprised of means for determining which middle stage switches are idle at a given time in the network. The controller is also comprised of means for choosing middle stage switches from only the idle middle stage switches to form a desired broadcast connection between an idle input port and a plurality of idle output ports. Preferably, the choosing means chooses the minimum number of idle middle stage switches to form the desired broadcast connection.

摘要： A method and apparatus for achieving fault tolerance in a computer system having at least a first central processing unit and a second central processing unit. The method comprises the steps of first executing a first algorithm in the first central processing unit on input which produces a first output as well as a certification trail. Next, executing a second algorithm in the second central processing unit on the input and on at least a portion of the certification trail which produces a second output. The second algorithm has a faster execution time than the first algorithm for a given input. Then, comparing the first and second outputs such that an error result is produced if the first and second outputs are not the same. The step of executing a first algorithm and the step of executing a second algorithm preferably takes place over essentially the same time period.

摘要： A network over which a medium is transferred. The network includes S core rings. Each core ring can be modeled as a set of nodes interconnected by links, where S is greater than or equal to 4 and is an integer, each said core ring having at least N nodes, where N is greater than or equal to 4 and is an integer. Each node/link is configurable in terms of directing the medium from a given source toward a given destination, and where each of the core rings is directly connected by means of k spanning links, where k is greater than or equal to 2, so as to comprise a spanning ring to at least a second and a third of the other core rings. The combinations of core rings spanned by each core ring is such that there is a path comprised of links and nodes from each node on any core ring to any other node on any other core ring. A method for transferring a medium.

摘要： The present invention pertains to a broadcast network. The broadcast network comprises N transmit stations, with each transmit station being capable of transmitting a signal and N being an integer .gtoreq.1. There are also M receive stations, where M is an integer .gtoreq.2; I switching stages where I is an integer .gtoreq.0 and a broadcast hub. The broadcast hub and I switching stages are connected such that they are capable of linking the N transmit stations to the M receive stations so that any one of the N transmit stations can transmit a signal to L of the receive stations, where L is an integer and 2.ltoreq.L.ltoreq.M, but each receive stations can receive a signal from only one of the N transmit stations at any given time. The broadcast hub and switching stages link more than one of the N transmit stations to desired receive stations at any given time.
