There is an other way to send Host-to-Host Intent to ONOS with specified bandwidth using BandwidthCalendaring app but this is out scope of this tutorial.which is explained in next section. 

Demo 3: Establishing connection between hosts/DataCenters using Calendering app.

TBD

Demo 4: Link recovery at Optical Layer:

In this section we gonna demonstrate how failure in optical layer can be recovered by ONOS in pinch on second without  disturbing the traffic flow.

Two see the what path is taken by certain host to send traffic (in GUI of course), you can click on that Host and click on show related traffic. You will see something similar to figure show below.

Image Added

Yellow path shows packet layer path and purple path shows optical layer path.

Now we will introduce failure in optical path of the traffic flow. We need to get into linc-oe console to introduce failure in optical switch. To do so do following,

This will get you into the command prompt of linc-oe.
