A data processing system comprising first and second computers (101;201) and respectively associated first and second transducers (103A; 203A) connected via respective first and second data highways (102;202) to their associated computers, the transducers being enabled upon receipt of associated predetermined address codes output by the computers on respective first and second address highways (110;210), the address highways being linked (310), the data highways being linked (302) and the comput...

An electronic document distribution network is provided having a uniform data stream which may be used by data processors of varying levels of data processing capability interconnected in the network. The network comprises a plurality of linked communicating data processors. Each of the processors has apparatus for receiving and for transmitting a uniform data stream which is representative of the content and format of the document as well as the processing to be performed with respect to the do...

This disclosure relates to a network of reduction processors for the evaluation of one or more functions which are stored in memory in the form of a series of nodes of a treelike graph where the nodes implement a variable-free applicative language. The respective function operators are reduced through a progressive series of transformations or substitutions until a result is obtained. During the reduction process, the processor transfers nodes to and from memory and performs various operations a...

Local area network control block (LCB) hardware and a method is disclosed which forms a prime vehicle of intercommunication between controller coupled local area networks (LANs), comprising a plurality of computer systems. An LCB has a predetermined format and is assembled by the computer hardware to provide information to the controller regarding the routing and transfer of a variable quantity of data between LANs.

A method allows for the communication of an electronic message between an enrolled user linked to a computer network and an unenrolled recipient. A recipient is designed for delivery of an electronic message from an enrolled user of a computer network. It is determined if the designated recipient is an enrolled user in the computer network. Then, in the event the designated recipient is not an enrolled user of the computer network, it is determined automatically whether the designated recipient ...

A massively parallel processing system comprising a plurality of processing nodes controlled in parallel by a controller. The processing nodes are interconnected by a plurality of communications links. Each processing node comprises a memory, a transposer module and a router node. The memory stores data in slice format. The transposer module is connected to the memory and generates transpose data words of selected ones of the data slices from the memory. The router node is connected to the trans...

A method and apparatus for determining whether an alias (or entity name) is available for use in a communication system. A transmitting node or entity transmits a first signal including the alias over the communication system. The alias includes a zone name. If the transmitting node receives a reply signal to the first signal, then the alias is not available for use. Otherwise the alias is available for use. The transmitting node transmits the first signal to a first router connected to a first ...

An enhanced intervention list is used in a data communication network used to route messages from a source or originating user to a destination user in the network. The enhanced intervention list includes an intervention type field which defines how an intercepted distribution is to be processed. For an Associative Redirection intervention type, the message is redirected to a destination user identified in the intervention list. For a Predirecting Intervention type, the message is diverted to an...

A self-timed data streaming receiver for a routing chip. Incoming flits are received by a distributor that distributes the flits between two self-timing FIFOs. A collector coupled to both FIFOs at their opposite ends takes the two streams of flits and recreates the original stream of flits prior to coupling the flits to routing control circuitry. A self-timed data streaming transmitter is also described.

A hierarchical network hierarchically connects a plurality of networks whose nodes are mutually connected by connection paths as a p-array n-dimensional cube to configure a single network. A plurality of nodes are selected from lower layer p-array n-dimensional cubes, and the selected gate nodes are mutually connected as a p-array m-dimensional cube to configure a p-array m-dimensional network on the next layer. Similarly, gate nodes are selected from a plurality of next-layer p-array m-dimensio...
