摘要： A method is described to operate a crossbar switch comprising a crossbar fabric with N sending and M receiving ports, with port cards connected to at least one sending and/or receiving port each of the crossbar fabric, said crossbar switch further comprising a control unit connected with the port cards via discrete control channel links, wherein C ports are clustered on a single receiving port card so that such a receiving port card in a single time-step can receive up to C data cells from C sending port cards simultaneously. According to said method the control channel links are used to relay up to C acknowledgements between at least one receiving port card and at least one sending port card.

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： Method and Switching fabric for ccounteracting a saturation tree occurring in a network with nodes An example of a method comprises the steps of generating at a local node where a congestion emerges a first congestion information; sending the first congestion information to at least one upstream node; responsive to one received first congestion information comparing the content of the received first congestion information with a present local status based on a set of predefined rules in order to identify at least one packet stream causing the congestion, and generating a second congestion information comprising the identified at least one packet stream causing the congestion; and sending the second congestion information to at least one further upstream node from where the identified at least one packet stream was received.

摘要： The invention is related to a switching arrangement for transporting data packets which comprise a section with data packet destination information and a payload section, to one or more output ports. The switching device is able to route the arriving data packets according to the data packet destination information, to at least one dedicated of the output ports. It comprises at each input port an input buffer with at least as many single input queues as there are output ports, and an input controller for each input port, serving for controlling the order of multiplexing the data packets from the input queues of the corresponding input buffer to the switching device. The input buffer comprises a demultiplexer for making for each of the arriving data packets an entry into those of the input queues, which are identified in the packet destination information of the corresponding data packet, whereby each input controller is designed to allow simultaneous transmission of those data packets whose entries are located in different input queues and whose payload sections have identical content.
