    摘要： Additional routing information is added to a transaction packet without recalculating an ECRC by inserting the additional routing information at predetermined bit positions in the transaction packet known to have predetermined bit values. The modified transaction packet can then be routed using the additional routing information. The predetermined bit values can subsequently be reinstated at the predetermined bit positions in the packet.

    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 infrastructure element can receive a first DMA request including a first address and the data, generate a meta request that comprises a resource key value and a doorbell address, and transmit the meta request via the infrastructure using the doorbell address. A remote DMA adapter can receive the meta request at the doorbell address and generate a remote direct memory access request message using the resource key, the first address and the data from the received meta request.

    摘要： An Infiniband device can be provided. The device can have an input port for receiving a packet. The port can be operable to extract a destination descriptor and a quality of service requirement descriptor for the packet and simultaneously to determine an output port of the device for onward transmission of the packet on the basis of the destination descriptor and to determine an output port virtual lane for each output port of the device on the basis of the quality of service requirement descriptor. The port can additionally be operable subsequently to use the determined output port to select between the determined output port virtual lanes.

    摘要： A PCI-Express interconnect device is provided. The device comprises: first and second upstream ports; first and second downstream ports; and a management entity. The management entity is operable to logically partition the device such that the first upstream port is operable to communicate with the first downstream port and the second upstream port is operable to communicate with the second downstream port. In one example, the management device is additionally operable to migrate the first downstream port from a partition in which the first downstream port is operable to communicate with the first upstream port into a partition in which the first downstream port is operable to communicate with the second upstream port.

    摘要： One embodiment of the invention provides a method of handling an incoming packet at a node in a network. The method includes associating at least one source identifier with a link into the node. A packet is then received at the node over the link, and a source identifier is extracted from the received packet. The extracted source identifier is compared with the source identifier(s) associated with the link in order to authenticate the packet.
