Abstract: In general, in one aspect, the disclosure describes a method includes accessing data of an egress packet belonging to a flow, storing data associating the flow with at least one queue based on a source of the data of the egress packet. The method also includes accessing an ingress packet belonging to the flow, performing a lookup of the at least one queue associated with the flow, and enqueueing data of the ingress packet to the at least one queue associated with the flow.

Abstract: Examples are disclosed for remotely initializing or booting a client or host device. In some examples, a network (NW) input/output (I/O) device coupled to a host device connects to a remote server via a NW communication link. For these examples, modules of the network I/O device establishes a control path to a non-volatile memory express (NVMe) controller maintained at the remote server using a remote direct memory access (RDMA) protocol. Properties of a storage device controlled by the NVMe controller have an RDMA service tag (STag) to indicate accessible allocated portions of the storage device. A system basic I/O system (BIOS) is capable of using the RDMA STag to access the storage device and load an operating system (OS) kernel. Also, one or more device drivers can remotely boot the host device using the RDMA STag.

Abstract: In one embodiment, a method is provided. The method of this embodiment provides performing packet processing on a packet, and placing the packet in a placement queue; if no read buffer is available, determining if the size of the placement queue exceeds a threshold polling value; and if the size of the placement queue exceeds the threshold polling value: if there are one or more pending DMM (data movement module) requests, polling a DMM to determine if the DMM has completed the one or more pending DMM requests for data associated with an application; and if the DMM has completed the one or more pending DMM requests, then sending a completion notification to the application to receive the data.

Abstract: Techniques for accelerating network receive side processing of packets. Packets may be associated into flow groupings and stored in flow buffers. Packet headers that are available for TCP/IP processing may be provided for processing. If a payload associated with a header is not available for processing then a descriptor associated with the header is tagged as indicating the payload is not available for processing.

Abstract: In general, in one aspect, the disclosure describes a method that includes accessing a packet, determining a flow associated with the packet, and determining, based at least in part on the packet, whether to remove the flow from a list of flows to handle using page-flipping.

Abstract: A method of maintaining network protocol timers in data structures associated with different respective processors in a multi-processor system. The timers accessed by a respective one of the processors include timers of connections mapped to the processor.

Abstract: Packet data received by a network controller is parsed and at least a portion of a received packet is stored by the network controller in both a host memory of a system and also in a cache memory of the central processing unit of the system. Other embodiments are described and claimed.

Abstract: In an embodiment, a method is provided. The method of this embodiment provides associating a receive packet with a selected one of a plurality of buckets in a table using a generated value based, at least in part, on the receive packet, and obtaining a connection context from the selected bucket. Other embodiments are disclosed and/or claimed.
