FlowER - a Erlang OpenFlow development platform

FlowER is a framework and a set of helper libraries to develop OpenFlow controllers in Erlang.


FlowER is build for deployment model that packages each Erlang application either as RPM or DEB package. Dependency resolution is done at install time and at build time to the package management tools. For manual building, the required dependencies therefore have to be installed manually.


Build Tool:

Support Appplications:


Run tetrapak build:

$ tetrapak build
== tetrapak:boot =================
Compiling tetrapak/flower_run.erl

Sample Switch

flower_simple_switch is a very basic Layer 2 learning switch. flower_tcp_transport listens for connection from OpenFlow datapath elements on the specified port. (in the following example, *:6633).

Run it like this:

$ erl -pa ebin
Erlang R15B (erts-5.9) [source] [64-bit] [smp:2:2] [async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.9  (abort with ^G)
1> application:start(sasl),
1> application:start(gen_listener_tcp),
1> application:start(regine),
1> application:start(flower).          
2> flower_simple_switch:start_link().
3> flower_tcp_transport:listen(6633,[]).
