A backplane controller to couple to a carrier interface and a plurality of host controllers of different types. The backplane controller is to identify a host controller corresponding to a type of a storage device of a storage device carrier. The storage device carrier is to interface with the carrier interface. The backplane controller is to arbitrate multiplexing of communication between the carrier interface and the identified host controller.

Backplane controller to arbitrate multiplexing of communication

In one embodiment an electronic device comprises at least one processor, at least one PCI express link, a virtual channel/sub-link flow control module, and a memory module communicatively connected to the one or more processors and comprising logic instructions which, when executed on the one or more processors configure the one or more processors to determine, in an electrical device, whether a virtual channel/sub-link is inactive, and in response to a determination that at least one virtual channel/sub-link is inactive, reallocate queue space from the at least one inactive channel to at least one active channel.

Queue sharing and reconfiguration in PCI express links

A network node within a network includes a first receive buffer, first buffer management, a second receive buffer and second buffer management. The first buffer management performs link level credit based flow control for network packets that the first buffer management places in the first receive buffer. The second buffer management performs end-to-end credit based flow control for network packets that the second buffer management receives from the first receive buffer and processes before placing data in the second receive buffer.

End-to-end flow control in a network

A system is provided comprising a fabric coupling together a plurality of computing devices, wherein the fabric transfers a stream of packets between the computing devices. Each computing device comprises a Quality of Service ('QOS') filter that monitors incoming packets to filter out packets of a maintenance type and permit transfer of packets of a transaction type.

Quality of service with control flow packet filtering

A direction of travel of a packet at a switch in an interconnection fabric that has multiple switches with ports is determined. A next turn pointer in the packet is used to identify turn bits in a routing path. The turn bits are then used to select an exit port as a function of the direction of travel of the packet.

Packet routing as a function of direction

In at least some embodiments of the invention, a system may comprise a plurality of electronic devices adapted to send and receive data, wherein each electronic device uses any one of a plurality of communication protocols. The system may also comprise a switch comprising a plurality of ports, each port is adapted to couple to an electronic device, wherein each port is configurable for use according to the protocol used by the electronic device coupled thereto.
