    摘要： Methods, apparatus, and systems for implementing in Network Interface Controller (NIC) flow switching. Switching operations are effected via hardware-based forwarding mechanisms in apparatus such as NICs in a manner that does not employ use of computer system processor resources and is transparent to operating systems hosted by such computer systems. The forwarding mechanisms are configured to move or copy Media Access Control (MAC) frame data between receive (Rx) and transmit (Tx) queues associated with different NIC ports that may be on the same NIC or separate NICs. The hardware-based switching operations effect forwarding of MAC frames between NIC ports using memory operations, thus reducing external network traffic, internal interconnect traffic, and processor workload associated with packet processing.

    摘要： Methods and apparatus for implementing Power over Ethernet (PoE) for auxiliary power in computer systems. Under aspects of the methods, one or more voltage inputs comprising standard power input is employed by a power control component in a network interface in an apparatus such as a network adaptor board, a System on a Chip (SoC), computer server or server blade to supply power to a network controller on the apparatus when the apparatus is operating at a normal power state. To enable the apparatus to maintain network communication when operating at a reduced power state, a PoE power input derived from at least one PoE signal received at at least one Ethernet jack of the apparatus is employed to provide power to the network controller absent use or availability of the standard power input. Accordingly, the PoE power input facilitates an auxiliary power function that may be used alone or in combination with existing (as applicable) auxiliary power input when apparatus are operated in reduced power states.

    摘要： A method according to one embodiment includes the operations of assigning a network application to at least one first core processing unit, from among a plurality of core processing unit. The method of this embodiment also includes the operations of assigning a first receive queue to said first core processing unit, wherein the first receive queue is configured to receive packet flow associated with the network application; defining a high threshold for the first receive queue; and monitoring the packet flow in the first receive queue and comparing a packet flow level in the first receive queue to the high threshold; wherein if the packet flow level exceeds the threshold based on the comparing, generating a queue status message indicating that the packet flow level in the first queue has exceeded the queue high threshold.
