One embodiment provides a network interface controller (NIC). The NIC can include a storage device, a network interface, a hardware list-processing engine (LPE), and a message state table (MST) logic block. The storage device can store an MST. The network interface can couple the NIC to a network. The LPE can perform message matching on a first packet of a message received via the network interface. The MST logic block can store results of the message matching in the MST and receive a request to read the results of the message matching from the MST if the NIC receives a second packet associated with the message.

A packet processing device includes: a line adapter configured to receive packets from a communication line; a packet combining unit configured to generate a combined packet by combining a plurality of packets received from the communication line; a packet memory configured to store packets received from the communication line; and a combined packet transferring unit configured to DMA transfer the combined packet generated by the packet combining unit to the packet memory. The combined packet transferring unit writes information of an address of first data of each packet inside the combined packet on the packet memory into a descriptor that is a data area on a memory set in advance.

Embodiments of the application describe a packet processing method and a router. The method includes: receiving, by an input line card, at least one packet; obtaining, by the input line card, information about an available first buffer block in a third buffer module, where the third buffer module is a first buffer module that includes an available first buffer block; allocating, by the input line card, a third buffer block to each of the at least one packet based on at least one buffer information block stored in the input line card and the information about an available first buffer block; and buffering, by the input line card, each packet into the third buffer block. Distributed packet buffering can be implemented by using the method.

The disclosure includes embodiments for a connected vehicle to form a vehicular micro cloud. In some embodiments, a method includes determining, by an onboard vehicle computer, that a queue is present in a roadway environment and that a vehicle that includes the onboard vehicle computer is present in the queue. The method includes causing a set of member vehicles to form a vehicular micro cloud in the roadway environment responsive to determining that the queue is present in the roadway environment so that determining that the queue is present triggers a formation of the vehicular micro cloud, where the vehicular micro cloud includes a set of vehicles which each share all of their unused vehicular computing resources with one another to generate a pool of vehicular computing resources that exceeds a total vehicular computing resources of any single member vehicle and is used to benefit the set of member vehicles.

Systems and devices can include a controller and a command queue to buffer incoming write requests into the device. The controller can receive, from a client across a link, a non-posted write request (e.g., a deferred memory write (DMWr) request) in a transaction layer packet (TLP) to the command queue; determine that the command queue can accept the DMWr request; identify, from the TLP, a successful completion (SC) message that indicates that the DMWr request was accepted into the command queue; and transmit, to the client across the link, the SC message that indicates that the DMWr request was accepted into the command queue. The controller can receive a second DMWr request in a second TLP; determine that the command queue is full; and transmit a memory request retry status (MRS) message to be transmitted to the client in response to the command queue being full.

A network interface controller (NIC) capable of facilitating fine-grain flow control (FGFC) is provided. The NIC can be equipped with a network interface, an FGFC logic block, and a traffic management logic block. During operation, the network interface can determine that a control frame from a switch is associated with FGFC. The network interface can then identify a data flow indicated in the control frame for applying the FGFC. The FGFC logic block can insert information from the control frame into an entry of a data structure stored in the NIC. The traffic management logic block can identify the entry in the data structure based on one or more fields of a packet belonging to the flow. Subsequently, the traffic management logic block can determine whether the packet is allowed to be forwarded based on the information in the entry.

Embodiments for implementing an enhanced network stack framework in a computing environment. A plurality of network buffers coherently attached between one or more applications and a network interface may be shared while bypassing one or more drivers and an operating systems using an application buffer, a circular buffer and a queuing and pooling operation.

The controller has a communication unit that receives read/write requests specifying an address of the same virtual area from a plurality of clients, and an actual area to be read/written by the communication unit. The communication unit has a management table that associates an identifier of the client with an address of the actual area that is different for each client, and an address conversion unit that carries out reading and writing to the address of the actual area associated with the identifier of the client with reference to the management table.
