SDN controllers - (Open Networking Part 3-2)

Hello Friends, thank you for providing feedback on my earlier posts related to Open Networking. This post is a part of series of posts related to Open networking with a special focus on optical SDN architectures. As promised in my earlier post let's understand more about other SDN controller architecture available from other vendors in the industry.

In my previous post, we discussed the transport controller solution provided by Fujitsu, Infinera, and Sedona. This week let's review the controller solution available from Juniper, NetFlex LightRiver, and Cisco. 

Juniper's Northstar controller based on PCE architecture defined in RFC 5440, supports source packet routing in networks(SPRING) to manage and optimize network resources and data plane.

   


Netflix from LightRiver is a multi-vendor Optical domain SDN controller supporting the integration of devices provided by many industry-leading vendors like Adva, Ciena, Cisco, Fujitsu, Infinera, Nokia.


Cisco provides the commercial distribution of OpenDaylight platform providing solution most relevant use case line Device and Topology management, Traffic engineering, and Network Function virtualization. In the Reference section, I have provided a link to an interesting Open controller document providing details of various use cases and other domain controllers like WAE, Cable controller, and Cisco NFVI, worth read. 

Additionally, Cisco DEVNET provides a rich community for learning and sandbox environments as well for those trying to learn coding and testing apps. Again worth a try, it is FREE!




With this post, I would complete my research on various controller architectures available (or being worked upon) in the industry. Next week we will deep dive into one of the architectures and understand various use cases and components common to most of these architectures. 

One important aspect that I was not able to complete in this section was the adoption of these architectures to solve real-world use cases. If you know this information it will be of great value to me if you can leave it as comments.

SDN controllers - (Open Networking Part 3-1)

Hello Friends, today, let's review different SDN controllers available in the industry and a high-level view of their design. I have tried my best to interpret the features published in the public domain and in case your interpretation is different please feel free to leave a comment and I will revise the post. 

Let's get started.....

As summarized in my previous post many service providers are transforming their Infrastructure to multi-vendor solutions. This migration enables the need to thoroughly validate hardware interoperation and a new requirement to build multi-vendor and multi-domain control and management plane software.

RFC8453 provides a framework for Abstraction and Control of TE  Networks (ACTN) to support virtual network services and connectivity services


Generalized Multi-vendor, Multi-domain architecture

There are many controller solutions available in the market and this week my attempt is to provide a brief overview of controller solutions from Fujitsu, Infinera, and Sedona







Next week I will post details for NetFlex LightRiver, Cisco, and Juniper solutions.

Again my attempt is to summarize and provide a starting point and you can make use of the reference link provided to explore further. 

I will be thankful if you can share(as comments) anything interesting you find during your research to augment my learning.
