Excerpt
Excerpt [0007] One attempt to make data movement more efficient over a network is the remote DMA (RDMA) protocol.......RDMA provides a protocol for one networked device to directly access memory in another network device without CPU involvement in the actual access.
[0012]In another embodiment, a system comprises at least a first node and a second node coupled to a network. The second node comprises a local memory and a direct memory access (DMA) controller coupled to the local memory. The first node is configured to transmit at least a first packet to the second node to access data in the local memory, and an address to be accessed in the local memory is included in a header of the packet. Responsive to the first packet, the DMA controller is configured to perform one or more transfers with the local memory to access the data at the address specified by the first packet. |
