Abstract: Some implementations relate to direct access to a storage device using a data plane of a switch. A response signal for a first packet transmitted from the switch to the storage device is received from a storage device. The first packet encapsulates a packet sequence number and first data to be transmitted by the switch. The response signal contains the packet sequence number. If the response signal is a negative acknowledgement response signal, a first state sequence number of the switch is updated with the packet sequence number contained in the response signal. The first state sequence number represents a sequence number of a packet to be transmitted by the switch. The first state sequence number and second data to be transmitted by the switch are encapsulated in a second packet to be transmitted to the storage device.

Abstract: In accordance with implementations of the subject matter described herein, there is provided a solution for streaming communication between devices. In this solution, a memory of a first device comprising a ring buffer is allocated to be dedicated for storing a data stream of an application to be transmitted to a second electronic device. The application of the first device writes data to be transmitted into the ring buffer, to form a portion of the first data stream, and a write pointer of the ring buffer is thus updated. A portion of data is read based on a source memory address from the ring buffer via the interface device. The interface device also transmits the data portion to a second device. The read data portion is stored in a dedicated ring buffer of the memory. In accordance with the solution, an efficient streaming communication interface is provided between devices.
