This document describes what is, how we can use it, how we extend it.

Tutorials and how to reproduce the experiment of WNS3 2013 paper is available dce-cradle-usecase.

What is ?

enables us to use Linux kernel via Direct Code Execution from the ns-3 native socket application. Applications can access it via ns-3 socket API. Currently (6th Jan. 2014) the following sockets are available:

  • IPv4/IPv6 UDP
  • IPv4/IPv6 TCP
  • IPv4/IPv6 RAW socket
  • IPv4/IPv6 DCCP
  • IPv4/IPv6 SCTP

Installing

is already integrated in ns-3-dce module. You can just build and install DCE as instructed in the parent document.

How to use it

OnOffHelper onoff = OnOffHelper ("ns3::LinuxTcpSocketFactory",
                                 InetSocketAddress (interfaces.GetAddress (1), 9));

How to extend it
