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)
