    摘要： The interconnecting network for switching data packets, having data and flow control information, comprises a local packet switch element (S1) with local input buffers (I(1,1) . . . I(1,y)) for buffering the incoming data packets, a remote packet switch element (S2) with remote input buffers (I(2,1) . . . I(2,y)) for buffering the incoming data packets, and data lines (L) for interconnecting the local and the remote packet switch elements (S1, S2). The interconnecting network further comprises a local and a remote arbiter (A1, A2) which are connected via control lines (CL) to the input buffers (I(1,1) . . . I(1,y), I(2,1) . . . I(2,y)), and which are formed such that they can provide that the flow control information is transmitted via the data lines (L) and the control lines (CL).

    摘要： A switching device is able to route the arriving data packets according to data packet destination information to dedicated output ports. The switching arrangement has, for each set of input ports in the switching device, a set of output buffers with an output buffer for storing the payload of each data packet at an address in the output buffer which pertains to the same set of output buffers and belongs to the dedicated output ports. At least one of the output buffers has a set of output queues with an output queue for each output port for storing the address of each payload stored in the corresponding output buffer. An arbiter controls a readout order of the stored addresses. For the output buffers which pertain to the same set of output ports a multiplexer multiplexes according to the readout order the payloads from the output buffers to the output ports.

    摘要： A method and systems for dynamically distributing packet flows over multiple network processing means and recombining packet flows after processing while keeping packet order even for traffic wherein an individual flow exceeds the performance capabilities of a single network processing means is disclosed. After incoming packets have been analyzed to identify the flow the packets are parts of, the sequenced load balancer of the invention dynamically distributes packets to the connected independent network processors. A balance history is created per flow and updated each time a packet of the flow is received and/or transmitted. Each balance history memorizes, in time order, the identifier of network processor having handled packets of the flow and the associated number of processed packets. Processed packets are then transmitted back to a high-speed link or memorized to be transmitted back to the high-speed link later, depending upon the current status of the balance history.

    摘要： For switching or transmitting data packets, one can provide communication systems which consist of several modules—operating in parallel on segments of a packet—to increase speed and handling capacity. One module acts as master (21), the others are slave modules (22) controlled by control signals (25) derived by the master module. It is important that in each module the data segment and the respective control signal of each packet are correctly synchronized, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.
