Hi, Remoting 2 uses plain Java socket API. Remoting 3 uses JBoss XNIO framework. To implement complicated protocol in the future, Netty might be used in conjunction with XNIO. Netty already provides XNIO transport so they can work together. On discovery, Remoting 2 uses its own mechanism based on multicast (or JNDI). Remoting 3, it's not implemented yet. Ron and David, please correct me if I'm wrong. :) HTH, View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4232477#...
