SMUX
A stream multiplexing library for Golang with minimal memory usage
...The library uses sessions, streams, and frames to manage many independent data flows over a single connection. It focuses on controlled memory usage, smooth receiving behavior, fair traffic shaping, and small protocol overhead. Its design includes a session-wide receive buffer, minimized 8-byte headers, and per-stream sliding windows in newer protocol versions. smux is especially useful for networking software that needs efficient connection management without opening a separate socket for every stream.
