XIPC is a middleware product that manages interprocess communication across programs in a network. A process is a unit of work associated with a particular user request (for example). Completing that work usually involves creating other processes or communicating between processes. This interprocess communication is performed using:
- Message queueing
- Memory sharing
XIPC allows a programmer to use these interprocess communication methods across processes that are distributed in different locations in a network so that the programmer need not be aware of the network or individual process locations. To do this, XIPC adds peer-to-peer messaging to the IPC methods. The developer of XIPC, Level 8 Software, calls this "message-oriented middleware (MOM)."
