7. Netty.io
Netty is a non-blocking I/O (NIO) client-server framework
for the development of Java network applications such as
protocol servers and clients.
The asynchronous event-driven network application
framework and tools are used to simplify network
programming such as TCP and UDP socket servers.[2]
Netty includes an implementation of the reactor pattern of
programming.
