Stream multiplexing for Go

What is stream multiplexing?

Imagine you have a single stream (a bi-directional stream of bytes) like a TCP connection. Stream multiplexing is a method for enabling the transmission of multiple simultaneous streams over the one underlying transport stream.

What is muxado?

muxado is an implementation of a stream multiplexing library in Go that can be layered on top of a net.Conn to multiplex that stream. muxado's protocol is not currently documented explicitly, but it is very nearly an implementation of the HTTP2 framing layer with all of the HTTP-specific bits removed. It is heavily inspired by HTTP2, SPDY, and WebMUX.

How does it work?

Simplifying, muxado chunks data sent over each multiplexed stream and transmits each piece as a "frame" over the transport stream. It then sends these frames, often interleaving data for multiple streams, to the remote side. The remote endpoint then reassembles the frames into distinct streams of data which are presented to the application layer.

What good is it anyways?

A stream multiplexing library is a powerful tool for an application developer's toolbox which solves a number of problems:

  - It allows developers to implement asynchronous/pipelined protocols with
    ease. Instead of matching requests with responses in your protocols, just
    open a new stream for each request and communicate over that.
  - muxado can do application-level keep-alives and dead-session detection so
    that you don't have to write heartbeat code ever again.
  - You never need to build connection pools for services running your
    protocol. You can open as many independent, concurrent streams as you need
    without incurring any round-trip latency costs.
  - muxado allows the server to initiate new streams to clients which is
    normally very difficult without NAT-busting trickery.
