Build a three-point virtual network based on Ovs,ovx,pox on mininet

This test is based on the Mininet platform, using OvS to create 1 new switches in the platform, pox as the controller, OVX as the middle tier for virtualization.

Basis please refer to http://ovx.onlab.us/getting-started/tutorial/

But since the above is just a straight line topology, and the middle does not pass through the nodes, we are going to build a complex topology, such as the red-labeled topology

First we will modify the pox l2_learing, that is, the Host,switch and path information written in

Next Turn on Ovx,pox

The specific code in/ovx/utils/is as follows:

Create a new virtual network and set the IP domain of the controller and host

Python ovxctl.py-n createnetwork tcp:192.168.100.107:6633 10.0.0.0 16

New Virtual Switch dpid by switch

Python ovxctl.py-n createswitch 1 00:00:00:00:00:00:02:00
Python ovxctl.py-n createswitch 1 00:00:00:00:00:00:05:00
Python ovxctl.py-n createswitch 1 00:00:00:00:00:00:08:00

Add port for each virtual switch, specify physical port, note the virtual port_id returned

Python ovxctl.py-n createport 1 00:00:00:00:00:00:02:00 5
Python ovxctl.py-n createport 1 00:00:00:00:00:00:02:00 6

Python ovxctl.py-n createport 1 00:00:00:00:00:00:05:00 5
Python ovxctl.py-n createport 1 00:00:00:00:00:00:05:00 6

Python ovxctl.py-n createport 1 00:00:00:00:00:00:08:00 5
Python ovxctl.py-n createport 1 00:00:00:00:00:00:08:00 7

Connection Switchs, here 10 10 is because we have changed the protocol and supported Ooe.
Python ovxctl.py-n connectlink 1 00:a4:23:05:00:00:00:01 2 00:a4:23:05:00:00:00:02 1 SPF 1
Python ovxctl.py-n connectlink 1 00:a4:23:05:00:00:00:01 1 00:a4:23:05:00:00:00:03 1 SPF 1
Python ovxctl.py-n connectlink 1 00:a4:23:05:00:00:00:02 2 00:a4:23:05:00:00:00:03 2 SPF 1

Create a new port and connect to host via the port

Python ovxctl.py-n createport 1 00:00:00:00:00:00:02:00 1
Python ovxctl.py-n connecthost 1 00:a4:23:05:00:00:00:01 3 00:00:00:00:02:01

Python ovxctl.py-n createport 1 00:00:00:00:00:00:05:00 2
Python ovxctl.py-n connecthost 1 00:a4:23:05:00:00:00:02 3 00:00:00:00:05:02

Python ovxctl.py-n createport 1 00:00:00:00:00:00:08:00 3
Python ovxctl.py-n connecthost 1 00:a4:23:05:00:00:00:03 3 00:00:00:00:08:03

Turn on the virtual network

Python ovxctl.py-n startnetwork 1

We can view flow table information in Mininet dump_flows
