Help: Hypothetical SDN Network Solution


So I this year I am studying a BTech in Communication Networks which basically is a Bachelors with a heavy Cisco network influence. One of my modules is a project/mini treatise. I decided to explore a solution that makes use of SDN (yes I understand SDN is quite an umbrella term but that allows free reign in my case).

One of the chapters is the proposed solution for a section of the network.

My questions are:

  • What tools can I use to design a proof of concept network? I was thinking that if I used something like GNS3 and configured a network using it then I can just play it off as the virtualized part of the network?

  • Does anyone have any material on SDN that could pose useful? I've read so many journals at this point I feel like my eyes want to pop out.

  • Where can I find some kind of catalog of SDN based devices, like the controllers and the bare bone packet forwarding devices? Reason being is that I need a cost sheet.

  • I have skimmed over Cisco DNA (Cisco's proprietary solution I believe). Should I look more into DNA or stick to the more open source 'Applications'?

Any information would be awesome!

Along with other info others will no doubt post you should at least be reading these:

If you are good at the Linux console/networking you can use mininet, is what everyone uses (along with EveNG) to make network simulations.

GNS3 is fine for this.

Play around with OpenDaylight maybe.

You have two choices: traditional SDN or SDN by API/CLI

Bullet 1: Vagrant + NOS (example:, GNS3, mininet -..- combined with a controller, automation platform, python script.

Bullet 2 + 3: use this as a starting point and branch out. you will be reading a lot more.

Bullet 4: stay with the open software. cisco has an open controller but i won't speak on how useful it is

level 1

The Ubiquiti Unifi controller and their whole UniFi range of devices sound perfect for this. They don't use a licensing model and the range is relatively small, which would make it easy to put together.

Unless you must use Cisco for the project.

You should avoid comments like this. It helps no one and actually annoys me, too. Help or leave.
