Net4j is an extensible '''client-server communications platform''' based on OSGi but also executable stand alone. You can easily extend the protocol stack with [[Eclipse]] plugins that provide new transport or application protocols. Net4j's focus on performance and scalability is featured by non-blocking I/O, zero-copy signals and multiplexed binary protocols. Net4j was originally developed to support the [[CDO]] technology for distributed shared and persistent [[EMF]] models but can also multiplex your own user-supplied application protocols through the same socket connection.

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)


Transport Implementations

  • NIO-based TCP transport implementation (ITCPConnector, ITCPAcceptor)
  • In-process JVM transport implementation (IJVMConnector, IJVMAcceptor)
  • Polling HTTP transport implementation (IHTTPConnector, IHTTPAcceptor)


Examples

  • Extensible collaborations platform with buddy list, chat, fileshare, ...
  • JMS(TM) provider implementation (experimental but functional)
