摘要： A method and system for reducing arbitration latency employs speculative transmission (STX) without prior arbitration in combination with routing fabric scheduled arbitration. Packets are sent from source locations to a routing fabric through scheduled arbitration, and also through speculative arbitration, to non-contentiously allocate outputs that were not previously reserved in the routing fabric to the speculatively transmitted packets.

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.

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.
