How to use

Prepare environment

Start Latency from karaf:

username@ubuntu:$(latency_directory)./karaf/target/assembly/bin/karaf

After booting Latency project, we connect mininet to it.

In mininet VM:

username@ubuntu:sudo mn --controller=remote,ip=${controller_ip_address} --mac --switch=ovsk,protocols=OpenFlow13 --topo tree,depth=2,fanout=3

Now the environment is ready! Let's begin to test!

In Topology tag, we can see network topology.

In Yang UI tag, we can find "latency" restconf interface.

Path "latency/operations/network-latency", choose type "SWITCHES", send the input. Then we can see latency detecting of network in console.

Path "latency/operations/switch-switch-latency", fill in A switch dpId and B switch dpId, send the input. Then we can see latency dection between these two switches in console.
