Abstract: A method is disclosed for configuring a network, composed of a plurality of nodes, to satisfy grade-of-service constraints such as traffic load and cost and, upon configuration, routing of service requests through admissible routes in the network in correspondence to the configuration topology. Both the configuration and routing are mutually dependent upon the selection of a set of integers which provide distinct sums over the integers in the set. The integers determine link interconnections between the nodes and the distinct sums are indicative of the admissible routes.

Abstract: Methodology, and associated circuitry, for encoding and decoding signals utilize optimizing orthogonal code techniques that effect autonomy of communications and simplified signal processing, thereby improving reliability.Encoder (121) processes an incoming data stream by associating an optimizing orthogonal code with each binary one in the input stream and then by transmitting a series of rate-increased pulses over a path during intervals determined by the code for each of the binary ones.Decoder (131) is generally arranged as a correlation detector in that the decoder only responds to the particular optimizing orthogonal code for which it is configured. Sensors in energy transfer relation to the path are positioned at detection points on the path in correspondence to an assigned code. The outputs of the sensors are processed to produce a rate-decreased detected signal at the rate of the input stream whenever a rate-increased stream corresponding to the decoder configuration is propagating along the path.
