Hybrid remote direct memory access

Abstract:

A technique for remote direct memory access (RDMA) may include receiving a packet that was sent over a network, and determining the packet has metadata indicative of acceleration. The technique may also include selecting a queue having minimal storage stages to process the packet, and writing the data of the packet to an application memory using the datapath associated with the queue. Amended metadata can be generated to indicate that the data has been written to the application memory, and the amended metadata can be stored in a software accessible buffer.
