Abstract
An interprocess communication technique transfers a message from a first process' memory (on a first computer system) directly to a second process' memory (on a second computer system). The message is identified by a virtual address and possibly a memory handle. The message is not stored in intermediary memory, such as operating system buffer memory, during the transfer. The communication technique may also provide virtual to physical address translation and memory protection. Memory protection is provided by ensuring that the communicating processes own the memory (the contents of which includes the message) being transferred between them.
