Smux is a stream multiplexing library for Go that runs many logical streams over a single reliable connection such as TCP or KCP. It minimizes memory usage through a shared session-wide receive buffer, token-bucket flow control, and a slab-style frame allocator.
Use cases
- multiplex many logical streams over a single TCP connection
- reduce connection overhead for tunnel or proxy software
- power connection management for KCP-based transports
- control memory usage across thousands of concurrent streams
- implement fair bandwidth sharing between streams
- build reliable ordered streams over custom io.ReadWriteCloser transports
When to choose
- you need many concurrent streams over one connection in Go with low memory overhead
- you are building on kcp-go or a similar reliable underlying transport
- you need net.Conn-compatible streams with built-in flow control and traffic shaping
When to avoid
- you need HTTP/2 or gRPC-level multiplexing with request semantics
- your underlying transport is unreliable and you are not using KCP
- you work outside the Go ecosystem
