Installing Mininet 2.2.2 on Ubuntu 20.04

I tried to install mininet from source from the latest tag 2.2.2, as suggested in Mininet README.

$ git clone git://github.com/mininet/mininet

$ cd mininet

$ git checkout -b 2.2.1 2.2.1

$ cd ..

$ mininet/util/install.sh -a

However, it produces the below error.

Package iproute is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  iproute2:i386 iproute2

Package cgroup-bin is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  cgroup-tools

E: Package 'iproute' has no installation candidate
E: Package 'cgroup-bin' has no installation candidate

sudo apt-get install python-scapyBuilding from the master fixes it, but gives another error:
E: Package 'python-scapy' has no installation candidate

Install scapy and nettools too!

sudo apt-get install python-scapy

sudo apt-get install nettools

Now, repeat the steps to install mininet.

SENDIM for Incremental Development of Cloud Networks: Simulation, Emulation & Deployment Integration Middleware

This is my third and final paper at IC2E 2016. I presented it yesterday. I used a presentation style that is different than my previous presentations, just not to give a repeating feeling to the audience, as majority of them had attended one of my other two presentations. The presentation slides are given below.

SENDIM for Incremental Development of Cloud Networks: Simulation, Emulation \& Deployment Integration Middleware from Kathiravelu Pradeeban

Abstract: Cloud networks are tested over simulation, emulation, and physical environments at different stages of development. Configuration management tools manage deployments and migrations across different cloud platforms, mitigating tedious system administration efforts. However, currently a cloud networking simulation cannot be migrated into an emulation, or vice versa, without rewriting and manually re-deploying the simulated application. This paper presents SENDIM, a Simulation, Emulation, aNd Deployment Integration Middleware for cloud networks. As an orchestration platform for incrementally building Software-Defined Cloud Networks (SDCN), SENDIM manages the development and deployment of algorithms and architectures the entire length from visualization, simulation, emulation, to physical deployments.

Configuring Mininet with Floodlight Controller

Configuring Mininet with Floodlight controller is pretty straight-forward.

First, download and build Floodlight.

$ git clone git://github.com/floodlight/floodlight.git
$ cd floodlight
$ git checkout stable
$ ant
$ sudo mkdir /var/lib/floodlight
$ sudo chmod 777 /var/lib/floodlight

Once built, you can execute Floodlight by,
$ java -jar target/floodlight.jar

Execute Mininet and connect to the controller.
sudo mn --arp --topo tree,3,2 --mac --switch ovsk --controller remote,ip=127.0.0.1

Now if you connect to the Floodlight UI in browser, you may view the nodes emulated by Mininet.

Floodlight Dashboard

Network Topology

$ java -jar target/floodlight.jar

$ git clone git://github.com/floodlight/floodlight.git $ cd floodlight $ git checkout stable $ ant; $ sudo mkdir /var/lib/floodlight $ sudo chmod 777 /var/lib/floodlight - See more at: http://www.projectfloodlight.org/getting-started/#sthash.SaGU01pP.dpuf

Mininet on mininet on mininet.. :P

So, after running Mininet on Mininet, I decided to be crazier and run mininet on mininet on mininet on.. :P Had an interesting observation. Each keystroke was repeated as the length of loop, as you can see below. :D

Initially (as monitored from ODL/DLUX)

Since mininet can run applications that are installed on its host, why not run mininet on top of mininet, just for lulz? :P

Configuring OpenDaylight Helium with Mininet.

Last year I wrote a post on configuring OpenDaylight Hydrogen with Mininet. Since Helium is here now, you may like to use it instead. First download and configure OpenDaylight Helium. Check the accepted answer for this question to start it real quick.

Now you will be able to connect to Mininet as before.

Configuring OpenDaylight Controller with Mininet

OpenDaylight with network emulated by Mininet

Once you have built OpenDaylight controller (or just chose to use the built OpenDaylight controller bundle), you may build and test the SDN solutions, with either networks or networks of virtual machines. Network emulators such as Mininet provide an effective alternative for SDN prototyping. Mininet can easily be installed from the regular repositories in Ubuntu.

$ sudo apt-get install mininet

Run OpenDaylight Controller (often as super user, for the privileges).

$ cd ~/OpenDayLight/controller/opendaylight/distribution/opendaylight/target/opendaylight
$ ./run.sh

Starting Mininet, for example, with a three-level tree topology.
The below command creates a tree topology with 3 levels.

$ sudo mn --controller=remote,ip=127.0.0.1 --topo tree,3

The connected networked devices can be monitored from the admin console of OpenDaylight. In the default configurations, you may access the admin console in a browser from the url, http://127.0.0.1:8080, with user name and password 'admin'.


Different Topology options
Network topologies can be visualized using Mininet and OpenDaylight. While a few topologies are available out of the box with Mininet, more custom topologies can be programmed as well.

1. Single node with 5 ports 

$ sudo mn --controller=remote,ip=127.0.0.1 --topo single,5

2. Linear topology with 5 nodes

$ sudo mn --controller=remote,ip=127.0.0.1 --topo linear,5

3. Tree topology
a. 3-ary, 2 level tree

$ sudo mn --controller=remote,ip=127.0.0.1 --topo tree,depth=2,fanout=3

b. 3-ary, 4 level tree 
(This looks a bit messy)

 $ sudo mn --controller=remote,ip=127.0.0.1 --topo tree,depth=4,fanout=3

OpenDaylight wiki page mentions that only the Mininet in a VM (option #1) is tested with the OpenDaylight controller. However, as seen in this post, Mininet works well with OpenDaylight even in the Mininet installation from the packages (option #3).
