Patterned memory-network data transfer

A network device, comprising:

• a first interface, configured to communicate at least with a memory;
• a second interface, configured to communicate over a network with a peer network device;
• and
• circuitry, configured to pre-register a plurality of patterns of offsets, to pre-associate a memory key representing a memory space to be accessed with a given pattern from the plurality of patterns of offsets, to receive a request to transfer data over the network between the memory and the peer network device, wherein the request indicates the memory key, but not the given pattern pre-associated with the memory key, and to transfer the data in accordance with the request using the memory key and the given pattern pre-associated with the memory key.
