Day 43: Completion of Phase 2 - Zodiac FX connected to multiple controllers

In previous article, we discussed how to tackle DoS attacks on the controller initiated by the switch. We also saw the HAProxy configuration for the same. It is time for implementation now!!!

In today's article, I have also given a video on how the network will be working by the end of the setup. To ensure that the Zodiac FX switch is contacting multiple controllers in case one of them fail, we can just configure the controller IP address on the Zodiac FX switch as the load balancer IP address. When I was going through few articles yesterday, I realized that there are many sorts of load balancing mechanisms. I was trying to do the DNS load balancing mechanism thus far. But after understanding the article, I realized that a server-side load balancer would be better for my scenario. And the only change I made to the setup already built to convert it into a server-side load balancer was changing the controller IP address on switch to 10.0.0.5.

Although the architecture is working fine now when I perform a DoS attack, we shall look into the same tomorrow by trying out various test cases. You can refer to my GitHub page for the configuration files for HAProxy.

Day 12: Master Slave SDN Controller Architecture

In the previous post, I was struggling to figure out why all controllers can install flows in all switches irrespective of the code. Well, today the mystery is getting resolved. I found this book that explains beautifully the various roles that a controller can play. The three roles are: Equal : this happens by default all the equal controllers in a network that are connected to the switch can add and delete flows from it Slave: it has a read-only limitation to the switch openflow tables Master: very similar to the switch, but only 1 master can be connected to the switch at that point of time, and no other flows can intercept the communication between switch and master. I highly recommend you go through the above link to get a better picture. Since the default role of any controller is "Equal", we couldn't really differentiate between the three controller flows yesterday. But one good news from this is that we don't really need extensive coding to assi

Day 50: Tcpreplay and tcpliveplay approach

Today we shall be exploring how to copy and redirect the OpenFlow packets to more than one controller from the load balancer. The load balancer is anyway sending the OpenFlow packets to one of the slave controllers - c1 or c2. The packets sent to these two controllers needs to be sent to master controller so the master controller can update the new flows added by c1 or c2 on the switches. This ensures synchronization between controllers. There are two implementation methods to achieve the same: Copy all packets generated from the load balancer to the controller side. Only the packets having destination IP address of c1 and c2 can be redirected to the master controller. Thus we can prevent the packets which already are reaching the master controller to be sent as duplicates Copy and redirect packets from the slave controllers - c1 and c2. We need not take care of duplicate packets reaching master controller. This will reduce the time taken to redirect packets. Since the second a

Day 10: Mininet Simulation of a basic distributed SDN controller architeture

Hi and welcome back! We have not been able to update the blog since we were busy debugging and figuring out!!! We are back to give you an in-detail explanation of how we have simulated a basic distributed SDN controller architecture. Requirement: 2 Hosts Mininet up and running Ryu controller up and running on each 1 D-link switch We have used two linux machines with Ubuntu 16.04 OS running on them.  How to install Mininet? Run the following command on a terminal to install mininet: > sudo apt-get install mininet How to install Ryu Controller? Make sure to install Ryu controller on each of the Linux machines so that they can act as a controller. Run the following commands for a successful installation of Ryu controller: > git clone git://github.com/osrg/ryu.git > cd ryu > sudo apt-get install python-dev python-pip python-setuptools   > sudo pip install . > sudo pip install webob eventlet paramiko routes Set Up the network
