Open Source Network Clients in Java

XNIO is a simplified low-level I/O layer which can be used anywhere you are using NIO today. It frees you from the hassle of dealing with Selectors and the lack of NIO support for multicast sockets and non-socket I/O, while still maintaining all the capabilities present in NIO. XNIO provides a unique and easy-to-use API for combining blocking and non-blocking operations, even on the same channel, allowing you to take advantage of the simplicity and low latency of blocking I/O while still gaining the thread-conservative benefits of non-blocking I/O. XNIO vastly simplifies implementation of channels, opening the door to supporting higer-level transport concepts (like SSL or virtual channels) with the same simple API. XNIO also introduces a powerful callback-based interface which can greatly simplify traditional state machine-based non-blocking applications, as well as allowing you to hit the perfect balance between throughput and latency for your application.
