Version 1Version 1Capability-based IPC for Linux
Bus1 is a subsystem to provide object-oriented Inter-Process Communication on Linux. It is a lightweight and scalable way for services and operating system tasks to share signals, data and resources; while at the same time allowing modularization, privilege separation, information hiding and isolation.
Bus1 uses lightweight handles to represent objects. It supports single-copy data transfer, message multicast and gives global-order guarantees.
Bus1 itself does not maintain any globally shared state, all references to objects need to be explicitely handed out to be visible to a peer.
