RSocket


RSocket is an application protocol initially developed by , that supports Reactive Streams. The motivation behind its development was to replace hypertext transfer protocol, which is inefficient for many tasks such as microservices communication, with a protocol that has less overhead.
RSocket is a binary protocol for use on byte stream transports such as TCP, WebSockets, and Aeron. It enables the following symmetric interaction models via async message passing over a single connection:

It supports session resumption, to allow resuming long-lived streams across different transport connections. This is particularly useful for mobile‹–›server communication when network connections drop, switch, and reconnect frequently.
