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： A network switch device receives a communication packet having a source MAC address s and a destination MAC address d at a switch port p. Then, the network switch device determines whether a valid routing table entry (s, p) exists, there by indicating that the source MAC address s is reachable via a switch port p. The network switch device further determines for the destination MAC address d whether there is at least one switch port q for which a valid routing table entry (d, q) exists, there by indicating that d is reachable via a switch port q. When the routing table entries (s, p) and (d, q) exist, the network switch device routes the communication packet to the switch port q.

摘要： The present invention relates to switching in electronic networks. Many data transmission protocols and technologies used in such networks, such as TCP/IP and Ethernet, use variable-length packets for transmission. Often however, the nodes that make up these networks typically contain high-speed cell switches that only support fixed-size data units. To support variable-length packets in such a fixed-size cell switch non-interleaving switching and transmission must be offered. The present invention provides such a solution in essence by segmenting a variable-length frame into a plurality of fixed-length cells including a start-of-frame cell, one or more continuation cell(s), and an end-of-frame cell and routes said fixed-length cells through said switch, thereby providing, at an output of said switch, subsequent and deadlock-free transmission of consecutive cells of a certain frame, and block any cell of a different frame from interleaving. This leads to better average delay characteristics and removes the need for packet reassembly.
