If you’ve been waiting for a tech-heavy deep dive, then you’re in luck. In this episode we’re getting REAL nerdy — so we decided to bring out the big guns and invite two of the industry’s biggest networking geeks to discuss hyper-converged infrastructure. Naturally, we got our fearless co-founder and CTO JR Rivers into the recording booth so he could share his wisdom (and crack a few jokes, as usual).

And who did we invite to go toe-to-toe with JR on networking knowledge? None other than the one and only Greg Ferro, co-founder of Packet Pushers! We couldn’t be more excited that Greg agreed to join us in the recording booth and share his industry insights.

So, what data center networking topic did we decide was meaty enough for these guys to chew on? Because Greg and JR are all about looking toward the future and analyzing what they see coming up on the horizon, this episode is dedicated to hyper-converged infrastructure (HCI). How is HCI changing the way we look at network architecture? We’ll discuss these topics Continue reading

PQ 152: An IETF Update On RIFT, BIER, SD-WAN And More

Today, an update on some compelling projects at IETF 102. Ours guest are Jeff Tantsura and Russ White.

We review the following projects to see what’s new and understand what problems they’re solving:

  • RIFT (Routing In Fat Trees)
  • BIER (Bit Indexed Explicit Replication)
  • PPR (Preferred Path Routing)
  • YANG data modeling

We also look at the state of SD-WAN, which is a bit of the Wild West, to look at standards and interoperability efforts underway.

Jeff is the Head of Technology Strategy at Nuage Networks. He’s also deeply involved with the IETF as the Chair of Routing Area Working Group, the Chair of Routing In Fat Trees, a Member of Internet Architecture Board, and a Member of IP Stack Evolution.

Jeff has recorded with us several times before, most recently on Priority Queue 126, where Greg chatted with Jeff about the future of data center fabrics. Jeff, welcome back to Packet Pushers.

Russ White is a network architect, author, and blogger. Rush also chairs the Interface to Routing System and the Babel routing protocol efforts at the IETF, and is a reviewer in the IETF’s Routing Area Directorate.

Growing the Cloudflare Apps Ecosystem

Growing the Cloudflare Apps Ecosystem

Starting today we are announcing the availability of two key pilot programs:

Why now? Over the course of past few months we've seen accelerating interest in Workers, and we frequently field the question on what we are doing to combine our growing ecosystem around Workers, and our unique deliverability capability, Cloudflare Apps. To meet this need, we have introduced two programs, Apps with Workers and Workers Service Providers. Let’s dig into the details:

First, we are announcing the upcoming availability of Cloudflare Apps, powered by embeddable Workers. This will allow any developer to build, deploy and in the near future package Workers to distribute to third parties, all using the Cloudflare Apps platform. It will be, in effect, the world's first serverless Apps platform.

Today, it's easy develop Workers using with our UI or API. The ability to App-ify Workers opens up a whole new promise to those who prefer to deal in clicks and not code. For our Apps developers, Apps with Workers allows for more complex Apps offerings running on Cloudflare, and for our customers the next generation in Apps. So, while we are actively putting the finishing touches on Continue reading

TACC Tapped for NSF’s Next Supercomputer

The Texas Advanced Computer Center (TACC) will house the latest leadership-class supercomputer funded by the National Science Foundation, a project that stands as a tribute to the NSF’s continued efforts to push supercomputing projects and the latest indication of the ground the organization is losing to the Department of Energy (DOE) in this effort. …

Las Marías of Azacualpa: Internet for Raising Women’s Voices

Azacualpa Yamaranguila, a village in the Intibuca region in Honduras, is celebrating. And not for nothing. Last Saturday was a historic day as they accessed the Internet for the very first time. For many of us, the Internet is taken for granted, but for the Lenca people it started like a dream 6 months ago when the Internet Society Honduras’ Chapter gave them the idea of connecting their village to the Internet. This idea became a reality thanks to the collective effort of the community and the support of Beyond the Net.

Las Marías

The party is for everyone but it focuses on them: Las Marías. With great curiosity, the women of the community came to the celebration early.

When I arrived after a 4-hour trip from Tegucigalpa, they were already there, dressed in colorful clothing. They were selling their products, taking care of their children, and anxiously awaiting the inauguration of the first community network of Azacualpa.

It was also the first anniversary of the radio ‘La Voz de las Mujeres’ (‘The Voice of the Women’) and María Santos, one of the heroes of the day and a leader of the community, was the first Continue reading

Computing should be based on light, not electricity, scientists say

Light-carrying, miniature wires are potentially more efficient for computing than other forms of interconnects, including copper and larger optical systems, say experts.However, there’s been a problem in getting such a nanowire system to work, the University of North Carolina at Chapel Hill, explains in an article published on Science Daily.“There hasn't been a controlled method for selectively sending light down along nanoscale wires,” says James Cahoon, a professor in the College of Arts and Sciences. “Optical technology has either used much larger structures or wasted a lot of light in the process.” Creating light uses power, defeating the object, for one thing.To read this article in full, please click here
