New user-visible features

  • Learning bridge (IEEE 802.1D): it is now possible to bridge together multiple layer 2 devices to create larger layer 2 networks. The Wifi and Csma models support this new mode of operation. (contributed by Gustavo Carneiro)
  • Python bindings: it is now possible to write simulation scripts in python using our python bindings (contributed by Gustavo Carneiro).
  • Real-time simulator: it is now possible to run simulations synchronized on the real-world wall-clock time (contributed by Craig Dowell).
  • Network Simulation Cradle: it is now possible to use the Network Simulation Cradle (http://www.wand.net.nz/~stj2/nsc/) in ns-3 and run simulations using various versions of kernel TCP network stacks. (contributed by Florian Westphal as part of his Google Summer of Code work)
  • A statistics framework: Joseph Kopena contributed a statistics framework which can be used keep track of simulation data in persistent storage across multiple runs (database and ascii file backends are available). More information on the wiki here
