Aleph is a Clojure framework for asynchronous communication, built on top of Netty and Lamina

Aleph allows the creation of both clients and servers that can communicate using an array of protocols (HTTP, WebSockets, TCP, UDP, and others), and represents that communication via a single abstraction, channels. Because of the underlying libraries and the event-driven approach to communication, these clients and servers can be highly scalable.
