Ranch is a socket acceptor pool for TCP protocols.

Ranch aims to provide everything you need to accept TCP connections with a small code base and low latency while being easy to use directly as an application or to embed into your own.

Ranch provides a modular design, letting you choose which transport and protocol are going to be used for a particular listener. Listeners accept and manage connections on one port, and include facilities to limit the number of concurrent connections. Connections are sorted into pools, each pool having a different configurable limit.

Ranch also allows you to upgrade the acceptor pool without having to close any of the currently opened sockets.
