On March 27, 2018, Cisco announced it was embracing disaggregation of the data center by allowing customers to run NX-OS on third-party switches and to use any network operating system on its Nexus switches. It’s certainly an interesting move, considering that they’re the company that claimed to have killed white-box networking.
…But does this model REALLY fit the definition of network disaggregation? What does true data center disaggregation look like? Why did Alanis Morissette name the song “Ironic” when none of the lyrics are examples of irony?? To answer these questions, I invited Ben Ritter (Consulting Engineer, Cumulus Networks) and Rama Darbha (Senior Consulting Engineer, who you’ll remember from our second episode — get ready for more #RamaRants!) into the recording booth so we can get to the bottom of this. In addition to breaking down the definition of data center disaggregation, Rama, Ben and I go full John Lennon and imagine a perfect world, where Cisco actually embraces the true spirit of disagreggation. How would this impact the industry? Imagine there’s no black box…it’s easy if Continue reading

Another lesson is that privacy defenses don’t need to be perfect. Many researchers and engineers think about privacy in all-or-nothing terms: a single mistake can be devastating, and if a defense won’t be perfect, we shouldn’t deploy it at all. That might make sense for some applications such as the Tor browser, but for everyday users of mainstream browsers, the threat model is death by Continue reading

Show 399: Open Networking In Production
Today, we talk to network architect Andrey Khomyakov, who s helped his organization make the transition from traditional to open networking in production.
What s it like to disaggregate switch hardware from network operating system? Was it hard? Does it really work? What s support like? Was any money saved? Will I get fired for suggesting my company go the open networking route? Andrey will answer these and more questions.
Pete Lumbis, long time friend of the Packet Pushers and contributor to the networking community, also joins with some of his insights learned in his role at Cumulus Networks. This is not a sponsored show. We just want to share the real-world experience of going new-school disaggregation with your networking.
We’ll look at the distinctions between open networking, disaggregation, and whitebox. We’ll also look at day-to-day operations with whitebox, common problems, how to choose a whitebox, and more.

Community Networks Can Help Solve World’s Problems, Ebook Says
By bringing broadband to new areas, community networks can help end discrimination, fight climate change, and feed the hungry of the world, says a report newly available as an ebook.
Community networks can help the United Nations achieve its Sustainable Development Goals, including an end to poverty and universal clean water, by bringing Internet service, and along with it, investment into areas not yet covered, says the report, Community Networks: the Internet by the People, for the People.
For the U.N. to reach its Sustainable Development Goals by 2030, nations and organizations will need to spend approximately US$1 trillion, noted Kathryn Brown, president and CEO of the Internet Society and a coauthor for the report.
While the goals are ambitious, they can be accomplished, with help from Internet access, Brown wrote in the report. “The Internet itself is an enabler for the goals,” she said. “We will be able to get there faster and in a way that lasts, if everyone can access the Internet and benefit from it.”
The report, available online since December, was recently released as a ebook on Amazon.com as a way to more widely distribute it. Supported by the Internet Society, Continue reading
Friday Musings on Network Analytics
I’ve been at Networking Field Day this week, and as always the conversations have been great and focused around a variety of networking topics. One that keeps jumping out at me is network analytics. There’s a few things that have come up that were especially interesting to me:
- Don’t ask yourself if networking monitoring is not worth your time. Odds are good you’re already monitoring stuff in your network and you don’t even realize it. Many networking vendors enable basic analytics for troubleshooting purposes. You need to figure out how to build that into a bigger part of your workflows.
- Remember that analytics can integrate with platforms you’re already using. If you’re using ServiceNow you can integrate everything into it. No better way to learn how analytics can help you than to setup some kind of ticket generation for down networks. And, if that automation causes you to get overloaded with link flaps you’ll have even more motivation to figure out why your provider can’t keep things running.
- Don’t discount open source tools. The world has come a long way since MRTG and Cacti. In fact, a lot of the flagship analytics platforms are built with open source tools as Continue reading
