A hybrid deposit model for low overhead communication in high speed LANs

This paper presents a new, “hybrid deposit” model for low overhead communication wherein the sender directly deposits messages into the destination user-level memory. The destination address is a function of both sender state and destination state. The motivation is to increase the sender’s role in communication in order to simplify the destination’s role and thus enable fast, low-cost communication interfaces. The model separates data delivery from synchronization so as to enable the optimization of simple data delivery while leaving more difficult synchronization to other mechanisms.
