#Introduction As you know opendaylight comes with a list of plugins which help you configure how it works through REST. List of all installed plugins and their REST methods on an odl instance is accessible at :

http://CONTROLLER_IP:8181/apidoc/explorer/index.html

Which at the time of writing, this was the only tutorial I found.

This app is a blacklist tools, written using plugins:

opendaylight-inventory(2013-08-19)

network-topology(2013-07-12)

And the usage is:

list
disable[enable] HOST_NAME

#How it works? Project contains two file: connectionMannager.py containing the code, and data.xml containing body of massage sent to controller to write flow. ##Flow of operation:

• In Topo.updateTopo() topology is gotten in json format by GETing /restconf/operational/network-topology:network-topology, using requests.get( URL). Gotten topology is parsed using json.load()

• In Topo.buildNodes() we build a dictionary of nodes with their id as keys

• Enabling nodes is implemented by writing a flow to discard packets coming from wanted node and disabling by deleting this flow. PUTed massage:

  • Header:

    { 'Content-Type': 'application/xml', 'Accept':'application/xml'}
    

  • Authentication:

    Is in basic authentication

  • Body:

    body is the data.xml file which is filled in run time. Make sure table id and node id of URL and the body be same.
