__NOTOC__
The Net4j Signalling platform is an extensible client/server communications framework.<br>
Net4j eases the development of fast and maintainable application protocols that are independent<br>
of the physical transport medium. Transport protocols are pluggable and Net4j ships with support<br>
for TCP, HTTP and in-memory transport. The core of Net4j is a fast, asynchronous and non-blocking<br>
buffer multiplexing kernel, based on OSGi but also executable stand-alone.

'''The Net4j project is now integrated into the [[CDO]] project.'''<br>
'''[http://www.eclipse.org/cdo/downloads/ Downloads] and other resources are provided there.'''

==Core Features==
* Extensible signalling framework for '''application protocols''' (IProtocol, SignalProtocol)
* Extensible transport framework for '''physical transports''' (IConnector, IAcceptor)
* '''Multiplexing''' of different application protocols (IChannel)
* Fast, asynchronous and non-blocking '''buffering kernel''' (IBuffer)
<br>

==Transports==
* NIO-based '''TCP''' transport implementation (ITCPConnector, ITCPAcceptor)
* In-process '''JVM''' transport implementation (IJVMConnector, IJVMAcceptor)
* Polling '''HTTP''' transport implementation (IHTTPConnector, IHTTPAcceptor)
<br>

==Examples==
* Extensible collaborations platform with buddy list, chat, fileshare, and more. [[Net4j/Using_Net4j_example|Tutorial]]
