Frenetic is an open-source Software Defined Network (SDN) controller platform designed to make SDN programming easy, modular, and semantically correct.
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 a network programming language 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:
- Python
- OCaml
- REST and JSON (= any programming language!)
- Install VirtualBox from https://www.virtualbox.org/wiki/Downloads. Use the latest version platform package appropriate for your system.
- From https://s3.amazonaws.com/plasma-umass/frenetic-tutorial-vm.ova download the latest Frentic User VM – this file is about 2.8 GB and may take about 10 minutes or so to download.
- Import the .ova file into VirtualBox. This takes two minutes or so.
-
Start up a terminal window - – two are provided in the VM under Accessories: Byobu Terminal (which integrates nicely with tmux) and LXTerminal (which has graphical tabs). Either one will do.
-
Start up a Mininet sample network with a switch and 2 hosts:
$ sudo mn --topo=single,2 --controller=remote -
Try pinging the host h2 from the host h1:
mininet> h1 ping h2Unfortunately, the ping won't work because you don't have an SDN network program in place! Press CTRL-C to stop the pinging.
-
Start up another terminal window and start up Frenetic:
$ frenetic http-controller --verbosity debug -
In a third terminal window, start up the example program for the Python repeater:
$ python -m frenetic.examples.repeater -
Now, back in the window running Mininet, the ping should now succeed:
mininet> h1 ping h2Congratulations! You now have a working Software Defined Network.
