    摘要: An interconnect structure and method of communicating messages on the interconnect structure assists high priority messages to travel through the interconnect structure at a faster rate than normal or low priority messages. An interconnect structure includes a plurality of nodes with a plurality of interconnect lines selectively coupling the nodes in a hierarchical multiple-level structure. Data moves from an uppermost source level to a lowermost destination level. Nodes in the structure are arranged in columns and levels. Data wormholes through the structure and, in a given time-step, data always moves from one column to an adjacent column and while remaining on the same level or moving down to a lower level. When data moves down a level, an additional bit of the target output is fixed so data exiting from the bottom of the structure arrives at the proper target output port.

    摘要: A switching system. The switching system includes a first switch having a primary receive port and a secondary receive port. The switching system includes a second switch connected to the first switch. The second switch has n receive ports, where n is greater than or equal to 2 and is an integer. The second switch has m transmit ports, where m is greater than or equal to 2 and is an integer. The transmit ports are decoupled from the receive ports. The second switch has a connecting mechanism that includes a multicast mechanism which sends data out a primary transmit port of the m transmit ports to the primary receive port of the first switch to define a primary path, and out a secondary transmit port of the m transmit ports to a secondary receive port of the first switch to define a redundant path to the primary path so that if there is a failure of the primary path to provide the data to the first switch, the data is received by the first switch through the redundant path. The first switch has a mechanism for only accepting the data from the primary path unless the primary path has failed, in which case the data is received by the first switch through the redundant path. A switch. A method of switching data.

    摘要: An ATM switch includes a first stage, a second stage and a third stage each of which stages includes at least one basic switch, wherein the first stage, the second stage and the third stage are connected. The basic switch includes a part which refers to time information written in a header of an input cell and switches cells to an output port in an ascending order of the time information. In addition, the ATM switch includes a cell distribution part in the basic switch of the first stage. The cell distribution part determines a routes of a cell to be transferred such that loads of routes within the ATM switch are balanced. The ATM switch further includes an adding part which adds arriving time information to an arriving cell as the time information.

    摘要: Data from an STM (Synchronous Transfer Mode) network is converted into an ATM (Asynchronous Transfer Mode) cell by an interworking facility, and the ATM cell is input to the ATM network. If the input cell corresponds to a connection which requires voice processing, a voice processing trunk within a switch performs the processes such as an echo compensation process, an encoding process, a multiplexing process, etc. The switch outputs the cell to a trunk line of the ATM network.
