Direct Deposit StateLess Receiver Protocol (DDSLRP)

Classical data transfer protocols usually require several copies of data in intermediate buffers before and after transmission through the network.

In order to enhance performances, PCI-DDC implements a "remote write" primitive that directly fetch data from the local memory - in user space - and writes data directly into the remote memory - in user space too. This is a "Direct Deposit" Protocol. Furthermore, the sender processor defines the physical address where it wants the data to be written into the remote memory. This is a "StateLess Receiver" Protocol.
