Abstract
A method for communicating between devices in a network includes creating an I/O tunnel between a first device and a second device through the network. The I/O tunnel is associated with I/O resources in both the first device and the second device, and wherein at least one of the I/O resources comprises a buffer resource. A data transfer operation may be sent between the first device and the second device by consuming at least some of the I/O resources associated with the I/O tunnel. A plurality of commands or a plurality of responses can be aggregated into a single buffer resource. Upon completion of the data transfer operation, the I/O resources that are consumed are automatically renewed.
