Welcome to Frenetic

The languages used to program networks today lack modern features. Programming them is a complicated and error-prone task, and outages and infiltrations are frequent. Frenetic is an open-source Software Defined Network (SDN) controller platform designed to make SDN programming easy, modular, and semantically correct, based on programming languages with the following essential features:

  • High-level abstractions that give programmers direct control over the network, allowing them to specify what they want the network to do without worrying about how to implement it.

  • Modular constructs that facilitate compositional reasoning about programs.

  • Portability, allowing programs written for one platform to be reused with different devices.

  • Rigorous semantic foundations that precisely document the meaning of the language and provide a solid platform for mechanical program analysis tools.

You can build Frenetic-based network applications with:

  • OCaml

  • Python

  • REST and JSON (i.e., any programming language!)

Getting Started

Installation

  1. Install OPAM, version 2.0 or higher.

  2. Switch to OCaml version 4.11.0 or greater:

    opam switch 4.11.0    
    
  3. Install dune:

    opam install dune
    
  4. Install required OCaml dependencies. Note that dune can compute the list of dependencies,

    dune external-lib-deps --missing @all
    

    and you can install each using OPAM---for example:

    opam install ocamlgraph    
    
  5. Build Frenetic

    make && make install
    
  6. (Optional) install Mininet

Hello World in SDN

The following instructions assume a Linux host with Mininet installed.

  1. Start up a terminal window.

  2. Start up a Mininet sample network with a switch and 2 hosts:

    $ sudo mn --topo=single,2 --controller=remote
    
  3. Try pinging the host h2 from the host h1:

    mininet> h1 ping h2
    

    Unfortunately, the ping won't work because you don't have an SDN network program in place! Press CTRL-C to stop the pinging.

  4. Start up another terminal window and start up Frenetic:

    $ frenetic http-controller --verbosity debug
    
  5. In a third terminal window, start up the example program for the Python repeater:

    $ python -m frenetic.examples.repeater
    
  6. Now, back in the window running Mininet, the ping should now succeed:

    mininet> h1 ping h2
    

    Congratulations! You now have a working Software Defined Network.
