摘要:
Devices and techniques for indicating packet processing hints are described herein. A device may receive a data packet. The device may extract a match-action attribute from the data packet that specifies an action to be applied to the data packet. The device may generate a hint field based on the match-action attribute. The hint field may include information to be used for handling the data packet. Other embodiments are also described.

An embodiment may include circuitry that may be capable of performing operations that may include generating, at least in part, at least one message to announce that at least one network node (1) is requesting, at least in part, that one or more transmissions to the at least one network node be postponed, at least in part, and/or (2) is entering, at least in part after issuance of the at least one message, a relatively lower power state relative to a relatively higher power state. Additionally or alternatively, the operations may include, in response, at least in part, to the at least one message, postponing, at least in part, at least one intermediate node at least one transmission (received by the at least one intermediate node) to the at least one network node. Many alternatives, variations, and/or modifications are possible without departing from this embodiment.

Technologies for identifying a cache line of a network packet for eviction from an on-processor cache of a network device communicatively coupled to a network controller. The network device is configured to determine whether a cache line of the cache corresponding to the network packet is to be evicted from the cache based on a determination that the network packet is not needed subsequent to processing the network packet, and provide an indication that the cache line is to be evicted from the cache based on an eviction policy received from the network controller.

Embodiments of the invention are generally directed to systems, methods, and apparatuses for linear to physical address translation with support for page attributes. In some embodiments, a system receives an instruction to translate a memory pointer to a physical memory address for a memory location. The system may return the physical memory address and one or more page attributes. Other embodiments are described and claimed.

An embodiment may include circuitry to facilitate, at least in part, a first network interface controller (NIC) in a client to be capable of accessing, via a second NIC in a server that is remote from the client and in a manner that is independent of an operating system environment in the server, at least one command interface of another controller of the server. The command interface may include at least one controller command queue. Such accessing may include writing at least one queue element to the at least one command queue to command the another controller to perform at least one operation associated with the another controller. The another controller may perform the at least one operation in response, at least in part, to the at least one queue element. Many alternatives, variations, and modifications are possible.

A method and apparatus to reduce memory required in a network interface controller to store per flow state information associated with a network connection is provided. Instead of storing per flow state information for a connection in the network interface controller at an endpoint of the connection, the per flow state information for the connection is stored in memory external to the network interface controller. The stored state information is conveyed in a packet by the network interface controller between the endpoints of the connection. For a Transmission Control Protocol (TCP) connection, the state information is conveyed between the endpoints of the TCP connection in a TCP option included in the TCP header in the packet.

Examples are disclosed for use of vendor defined messages to execute a command to access a storage device maintained at a server. In some examples, a network input/output device coupled to the server may receive the command from a client remote to the server for the client to access the storage device. For these examples, elements or components of the network input/output device may be capable of forwarding the command either directly to a Non-Volatile Memory Express (NVMe) controller that controls the storage device or to a manageability module coupled between the network input/out device and the NVMe controller. Vendor specific information may be forwarded with the command and used by either the NVMe controller or the manageability module to facilitate execution of the command. Other examples are described and claimed.

Disclosed is a system and method for storing a plurality of data packets in a plurality of memory buffers in a cache memory for reducing cache conflicts. The method includes determining size of each of a plurality of data packets; storing a first data packet of the plurality of data packets starting from a first address in a first memory buffer of the plurality of memory buffers; determining an offset based on the size of the first data packet; and storing a second data packet in a second buffer starting from a second address based on the offset.
