SDN: Is Here to Stay
In an October 3, 2017 article published in Network Computing, titled: “SDN: Time to Move On,” Gartner Analysts report on the state of software-defined networking and advise enterprises to shift their focus. It has triggered some interesting conversation in the SDN field. As a leading player of SDN technology, we have received several inquiries for comments on the article. While the controversial title grabbed a lot of attention, it’s alarming to many and far from reality. More importantly, it differs from what Gartner reports have concluded.
From what we see in the market, SDN has already landed real use cases and built the momentum to change the production network. However, as Gartner expressed in the reports, we have seen two gaps in adopting SDN: It takes a long time for customers to adopt this nascent technology; and while SDN can be used to solve many imminent issues, it is not a panacea to all networking problems.
According to Gartner, “SDN started as a new technical architecture, but brought into light some valuable concepts that outlived the original blueprint,” Gartner VP Distinguished Analyst, Joe Skorupa and Research Director, Danilo Ciscato wrote. The article also reveals, “The story’s different in Continue reading

Choosing your chassis: a look at different models
Simplicity, scalability, efficiency, flexibility — who doesn’t want to be able to use those words when talking about their data center? As more and more companies adopt web-scale networking and watch their growth rapidly increase, the need for an equally scalable and powerful solution becomes apparent. Fortunately, Cumulus Networks has a solution. We believe in listening to what our customers want and providing them with what they need; that’s why we supports the Facebook Backpack for 64 to 128 ports of 100gig connectivity and the Edge-Core OMP800 for 256 ports of 100gig connectivity. So, what exactly is so great about these chassis? Let’s take a closer, more technical look.
The topology
When designing and building out new data centers, customers have universally agreed on spine and leaf networks as the way to go. Easy scale out by adding more leafs when server racks are added and more manageable oversubscription by adding more spines makes this design an obvious choice. We at Cumulus have built some of the largest data centers in the world out of one-rack-unit switches: 48 port leafs and 32 port spines. These web-scale data centers build “three-tier” spine and leaf networks using spine and leaf “pods” Continue reading

Applied Networking Research Prize: Winners Announced, Nominations for 2018 Now Open
As we rapidly approach the last Internet Engineering Task Force meeting for the year, we’re pleased to report that the final winners of the Applied Networking Research Prize (ANRP) for 2017 have been announced.
The ANRP awards for IETF 100 go to:
Paul Emmerich for developing the high-speed packet generator MoonGen.
Paul Emmerich, Sebastian Gallenmüller, Daniel Raumer, Florian Wohlfart, and Georg Carle, “MoonGen: A Scriptable High-Speed Packet Generator,” in Internet Measurement Conference (IMC) 2015, Tokyo, Japan, Oct. 2015.
Roland van Rijswijk-Deij for analysing the impact of elliptic curve cryptography on DNSSEC validation performance.
Roland van Rijswijk-Deij, Kaspar Hageman, Anna Sperotto and Aiko Pras, “The Performance Impact of Elliptic Curve Cryptography on DNSSEC Validation,” in IEEE/ACM Transactions on Networking, Volume 25, Issue 2, April 2017.
For the 2017 award period of the ANRP, 39 eligible nominations were received. Each submission was reviewed by several members of the selection committee according to a diverse set of criteria, including scientific excellence and substance, timeliness, relevance, and potential impact on the Internet. Based on this review, six submissions were awarded an Applied Networking Research Prize in 2017.
Paul and Roland will present their work at the IRTF Open Meeting during IETF 100 in Singapore. Continue reading

Network Automation Engineer Persona: Part Two
This article is number two in a series. The first part can be found here.
There has been a thought trend in the last few years leading network engineers to think they need to be developers. This is totally nonsense. When we want to learn a new skill, there is a precursor which says “I want to do X, so therefore I need to learn about what X”. If you’re thinking “I should be learning Python”, I ask to what goal? What is making you ask this question? Maybe the question should be, for a network automation engineer role, what skills do I need to learn? Stop guessing!
The Network Automation Engineer role combines deep network knowledge, with the ability to describe, collect and transmit domain specific data through one or more abstraction layer type components. It requires knowledge of how to collect data from databases and data-stores of various types. Where does a list of IP addresses get stored? How are they stored? How are they retrieved? The role requires an awareness of the cause for making a change and the implication of making them. Gaining the skills to become this persona isn’t a full career change, but a Continue reading
