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:
You can build Frenetic-based network applications with:
Install OPAM, version 2.0 or higher.
Switch to OCaml version 4.11.0 or greater:
opam switch 4.11.0
Install dune:
opam install dune
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
Build Frenetic
make && make install
(Optional) install Mininet
The following instructions assume a Linux host with Mininet installed.
Start up a terminal window.
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 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.
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 h2
Congratulations! You now have a working Software Defined Network.
Frenetic is an open source project, and we encourage you to contribute!
