Abstract: 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.

Abstract: 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.

Abstract: 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.
