Revision as of 02:19, 19 November 2013

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

The Net4j project is now integrated into the CDO project.
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)


Transports

  • 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, and more. Tutorial
  • JMS(TM) provider implementation (experimental but functional)
