摘要： 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.

摘要： Methods and apparatus are disclosed for virtualizable, forward-compatible hardware-software interfaces. Embodiments may be used in a driver whether it is a physical driver or a virtual driver. Commands are queued from the driver and fetched to the device. An actions table is accessed to determine if drivers are permitted to perform commands. Events are queued for the drivers responsive to commands. If drivers are not permitted to perform a command, device firmware may forward the command to a privileged driver to perform the required command. If a driver is only permitted to perform a command with assistance the command is forwarded for corrections and execution. If a command is to be dropped, a completion event may be queued as if the command had executed. Drivers may have no indication of which actions were taken. The actions table may be changed for hardware/software modifications or dynamically according to configuration changes.

摘要： 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.

摘要： 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.

摘要： Examples are disclosed for exchanging a key between an input/output device for network device and a first processing element operating on the network device. Data having a destination associated with the first processing element may be received by the input/output device. The exchanged key may be used to encrypt the received data. The encrypted data may then be sent to a buffer maintained at least in part in a memory for the network device. The memory may be arranged to enable sharing of the buffer with at least a second processing element operating on the network device. Examples are also disclosed for the processing element to receive an indication of the storing of the encrypted data in the buffer. The processing element may then obtain the encrypted data from the buffer and decrypt the data using the exchanged key.
