Transport Protocol and Interface for Efficient Data Transfer Over RDMA Fabric

A method of utilizing an interface using a protocol for network transport, comprising:

• providing the interface for network transport using the protocol between a first computing node and a second computing node, the protocol identifying a first threshold and a second threshold;
• at the interface, receiving a transfer request;
• determining a data size associated with the transfer request;
• using the protocol, based up the data size associated with the transfer request, selecting one of at least three transfer modes to perform the transfer request in accordance with the first threshold and the second threshold, wherein each transfer mode utilizes flow control and at least one RDMA operation;
• and
• using the protocol, utilizing the selected transfer mode to perform the transfer request.

A computer storage media storing computer-readable instructions that when executed cause a computing device to:

• provide the interface for network transport using a protocol between a first computing node and a second computing node, the interface identifying a first threshold and a second threshold;
• at the interface, receive a transfer request;
• determine a data size associated with the transfer request;
• using the protocol, based up the data size associated with the transfer request, select one of at least three transfer modes to perform the transfer request in accordance with the first threshold and the second threshold, wherein each transfer mode utilizes flow control and at least one RDMA operation;
• and
• using the protocol, utilize the selected transfer mode to perform the transfer request.
