摘要： One embodiment of the invention provides a method of operating a switch in a communications network. The method includes storing a set of routings for each port in the switch. When a packet is received at a port in the switch, the set of routings corresponding to the port at which the packet was received is accessed. A port from which to forward the packet from the switch is determined in accordance with the set of routings. The packet is then duly forwarded over the network from the port as determined by the routings.

摘要： One embodiment of the invention provides a method of operating a switch with cut-through routing in a communications network. The method includes receiving a packet at a first port of the switch and determining a second port of the switch from which the received packet is to be forwarded out over the network. At least one authentication check is performed on the received packet. In general, the switch starts to forward the received packet from the second port prior to complete reception of the packet at the first port. However, this onward transmission is delayed until the authentication check has completed. This ensure that none of the received packet is forwarded from the second port if any authentication check fails.

摘要： An Infiniband device is provided. The device has a plurality of input/output ports. Each port has associated therewith an input buffer for storage of a packet received at that port. Each port also has associated therewith a plurality of output buffers for storage of a packet transmitted from an input buffer via a switching matrix. Each port is arranged to share its associated plurality of output ports with at least one other port. Each input buffer is also associated with a single output buffer of each shared plurality of output buffers. A packet received at an input buffer is transmitted to all associated output buffers via the switching matrix in parallel with an output buffer select signal. The output buffer select signal is sent to less than all of the associated output buffers, any output buffer not receiving the output buffer select signal is configured to discard the packet transmitted from the input buffer.

摘要： An Infiniband switch can be provided. The switch can have an input port logic unit for determining an output virtual lane for a received packet and for storing a descriptor of the determined output virtual lane in a packet field not protected by a checksum field of the packet. The switch can also have a routing unit for transferring the received packet to an output port corresponding to the determined output virtual lane. Additionally, the switch can have an output port logic unit for simultaneously checking the integrity of the packet transferred through the routing unit and calculating a new value for the checksum with the descriptor moved to a correct packet field, which field is included in the calculation of the checksum.
