RSocket

http://rsocket.io/

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:

• request/response (stream of 1)
• request/stream (finite stream of many)
• fire-and-forget (no response)
• channel (bi-directional streams)
