This wiki is a user guide for our Buffer Interprocess Sharing project. ContentsWhat is Buffer Interprocess Sharing?Buffer Interprocess Sharing, or BIPS, is a variant of a common IPC that allows communication between processes. In this case, BIPS allows sharing data buffers between two or more processes with zero copy. They can be classified as Producers or Consumers according to their role in the system. The producer is responsible for generating and filling in the information on the buffers that the Consumers will read. The synchronization between these entities is handled by the Signaler, which ensures that all operations are concurrent-safe. This means that Consumers can only read buffers that are fully written by Producers and that Producers can only write buffers already read by Producers. These buffers are created and managed by a shared structure known as the Buffer Pool, which has a fixed capacity. The Signaler handles the synchronization between the BP and the Consumers/Producers.
Supported BackendsBIPS is used to communicate processes that need to share information, which helps optimize memory usage and application performance. BIPS supports:
