The Qnet protocol extends interprocess communication (IPC) transparently over a network of microkernels. This is done by taking advantage of the Neutrino's message-passing paradigm. Message passing is the central theme of Neutrino that manages a group of cooperating processes by routing messages. This enhances the efficiency of all transactions among all processes throughout the system.
For more information about message passing and Qnet, see Advanced Qnet Topics appendix.
