Project

Student implements a framework for building asynchronous (event-driven) network applications that will be compatible with all major Ruby implementations - JRuby, MRI, Rubinius. The framework will support multiple networking adapters and provide compatibility layer for EventMachine based applications.

Problem

There are many ways to implement asynchronous applications using low-level libraries - nio4r, java nio, netty, libuv and others. The challenge is to choose the right one and be able to switch it based on a deployment model.
