Key Features, Communication Modes, and Internal Implementation of RSocket

RSocket is a binary, back‑pressure‑aware protocol that supports four interaction models—fire‑and‑forget, request‑response, request‑stream, and request‑channel—using multiplexed frames with odd/even stream IDs for true bidirectional communication, and provides a reactive, resumable API suitable for microservices, IoT, and broker‑based architectures.
