ONOS tutorial with mininet : Part 1

ONOS

ONOS is an SDN controller specifically designed for service providers.Intention is to create a software defined network operating systems intended to integrate all network applications and functions in a viritualized format.The current ONOS version is 1.12.0.

Mininet

A network emulator which can create virtual switches,hosts and connect to SDN controllers. Mininet can be installed in your laptop and complex networking solutions and topologies can be tested out with ease .

Topology

S1-Switch which will be used to connect two hosts

H1 -host 1

H2 -host 2

The topology we are attempting to create here is a single switch and two hosts connected .SDN controller ONOS will be controlling the traffic flows between the devices
