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.

Open Networking Optical - Part1

Major goals for Open Networking have been to take the best components, hardware or software or both and build a best-in-class network architecture and network. Hardware and Software disaggregation is playing a key role in this journey and in the year 2021 accelerated deployment of such architectures is on the horizon.

Many of the below initiatives impact Optical networking as well and this blog is one of many in this series that will follow. The Optical Networking Digital symposium was organized last week(Feb 16 & 18)  and some of the keynotes touched upon building programmable disaggregated networks.

There are overlaps and contradictions in some of these initiatives and in the next post, my attempt will be to summarize how much work has been done on some of these projects. You can find references to all these projects below and feel free to share your thoughts and comments. Have a good day!
