摘要:
A switching system for routing information packets that can simultaneously receive a variety of packet formats. The packet formats include electronic packet transmissions, optical wave division multiplexed data (WDM) with a single frame consisting of a plurality of packets to be sent to a common output line, with each packet traveling on a separate wavelength, WDM packets where the header of an individual packet travels on a wavelength different from the remainder of the packet (i.e. the payload) and the payload either travels on a single wavelength or is subdivided into a plurality of sub-packets with each sub-packet carried on a separate wavelength, and the like. The system includes input devices, a scheduling unit, a switching unit; and variable delay line units. A deconcentrator in the packet switching system creates a minimum gap between packets.

An interconnect structure substantially improves operation of an information concentrator through usage of single-bit routing through control cells using a control signal. The interconnect structure and operating technique support wormhole routing and flow of messages. Message packets are always buffered within the structure and never discarded, so that any packet that enters the structure is guaranteed to exit. In one example, the interconnect structure includes a ribbon of interconnect lines connecting a plurality of nodes in nonintersecting paths. The ribbon of interconnect lines winds through a plurality of levels from the source level to the destination level. The number of turns of a winding decreases from the source level to the destination level. The interconnect structure further includes a plurality of columns formed by interconnect lines coupling the nodes across the ribbon in cross-section through the windings of the levels.

This invention is directed to a parallel, control-information generation, distribution and processing system. This scalable, pipelined control and switching system efficiently and fairly manages a plurality of incoming data streams, and applies class and quality of service requirements. The present invention also uses scalable MLML switch fabrics to control a data packet switch, including a request-processing switch used to control the data-packet switch. Also included is a request processor for each output port, which manages and approves all data flow to that output port, and an answer switch which transmits answer packets from request processors back to requesting input ports.

A network or interconnect structure which includes a plurality of nodes which are interconnected within a hierarchical multiple level structure. The level of each node is determined by the position of the node within the structure and data messages move from node to node from a source level to a destination level. Each node within the interconnect structure is capable of receiving simultaneous data messages at its input ports from any other node and the receiving node is able to transmit each of the received data messages through its output ports to separate nodes in the interconnect structure to one or more levels below the level of the receiving node.

An interconnect structure comprises a logic capable of error detection and/or error correction. A logic formats a data stream into a plurality of fixed-size segments. The individual segments include a header containing at least a set presence bit and a target address, a payload containing at least segment data and a copy of the target address, and a parity bit designating parity of the payload, the logic arranging the segment plurality into a multiple-dimensional matrix. A logic analyzes segment data in a plurality of dimensions following passage of the data through a plurality of switches including analysis to detect segment error, column error, and payload error.

An interconnect structure comprises a plurality of network-connected devices and a logic adapted to control a first subset of the network-connected devices to transmit data and simultaneously control a second subset of the network-connected devices to prepare for data transmission at a future time. The logic can execute an operation that activates a data transmission action upon realization of at least one predetermined criterion.
摘要:
An interconnect structure comprising a plurality of input ports and a plurality of output ports with messages being sent from an input port to a predetermined output port through a switch S. Advantageously, the setting of switch S is not dependent upon the predetermined output port to which a particular message is being sent.

An interconnect structure is disclosed comprising a collection of input ports, a collection of output ports, and a switching element. Data enters the switching element only at specific data entry times. The interconnect structure includes a collection of synchronizing elements. Data in the form of packets enter the input ports in an asynchronous fashion. The data packets pass from the input ports to the synchronizing units. The data exits the synchronizing units and enters the switching element with each packet arriving at the switching element at a specific data entry time.
