One-to-many interprocess communication in the V-system

Interprocess communication (IPC) normally allows one process to communicate with only one other process at a time. One-to-many IPC allows one process to communicate simultaneously with a group of processes., possibly of unknown membership. While the broadcast and multicast facilities of local networks support efficient one-to-many communication between hosts, its use between processes has been limited by the lack of support in the distributed operating system. This paper describes the integration of one-to-many communication into V interprocess communication system. We discuss the different models of use and the reliability and present some initial applications.
