xSocket is an easy to use NIO-based
library to build high performance, scalable network applications. It
supports writing client-side applications as well as server-side
applications in an intuitive way. Issues like low level NIO selector
programming, connection pool management, connection timeout detection
are encapsulated by xSocket.
With xSocket you are able to write high performance, scalable client
and server components such as SMTP Server, proxies or client and server
components which are based on a custom protocol.

xSocket core:
- Blocking and non-blocking connection support
- Blocking and non-blocking connection pooling (client-side
only)
- Dynamic callback handler architecture to provide asynchronous
communication approaches
- Configurable threading behaviour (multi-threaded, non-threaded)
on callback class and method level
- Quality of service management by providing dynamic data transfer
rate control
- SSL (which can also be activated in a ad-hoc manner)
- TCP and UDP transport protocol
- JMX-based monitoring and management
- OSGi and Maven support on deployment level
xSocket extensions:
- xSocket-multiplexed: Client- & server-side
multiplexing/multistreaming
- Blogging extension from The Blog Starter (Scott Chow)
- xLightweb (formerly
xSocket-http): Client- & server-side HTTP protocol support
(synchronous/asynchronous, blocking/non-blocking API). The http
module includes a HttpClient as well as a lightweight server
execution environment.
