What is DFZ (Default Free Zone)?

In the context of the Internet and BGP routing, DFZ – commonly known as Default Free Zone – refers to the collections of all the public IPv4 BGP prefixes without default route on the global Internet. Most of the time, you hear full-route or full-Internet-route terms which are the same with Default Free Zone term. Having all BGP routes, […]

Cloud28+ turns its cloud catalog into an enterprise app store

Cloud28+, the cloud services federation backed by Hewlett Packard Enterprise, now wants to help you install enterprise applications, not just choose them from its catalog. Although HPE is the driving force behind Cloud28+, the federation of independent software vendors, resellers and service providers now has 225 members, which are pushing to simplify cloud software deployment. The federation plans to open its new App Center for business later this summer, and will begin stocking its virtual shelves on June 7 with the opening of an App Onboarding Center. This will containerize workloads submitted by vendors and resellers and test them for compatibility, initially for free.To read this article in full or to leave a comment, please click here

OpenSwitch Meets P4

Note: This article was originally published here.

Before moving on the next post to continue our saga of OpenSwitch Simulations with GNS3, I wanted to take a quick deviation to document a subject that gets a lot of attention these days: P4.

In case you have been missing all the action around P4, the 30,000 feet view is that it’s a language to describe forwarding pipelines (and no, it’s not the same as OpenFlow, that is useful for programming entries in almost-always-pre-defined pipelines). One of the (many) nice things about this is that you can potentially ‘compile’ your pipeline definition into an executable program that provides a functional simulation of a P4-based ASIC. Did I mention the tools for doing all of this are available as open source?

What does P4 has to do with OpenSwitch?

Google has a new chip that makes machine learning way faster

Google has taken a big leap forward with the speed of its machine learning systems by creating its own custom chip that it's been using for over a year.The company was rumored to have been designing its own chip, based partly on job ads it posted in recent years. But until today it had kept the effort largely under wraps.It calls the chip a Tensor Processing Unit, or TPU, named after the TensorFlow software it uses for its machine learning programs. In a blog post, Google engineer Norm Jouppi refers to it as an accelerator chip, which means it speeds up a specific task.To read this article in full or to leave a comment, please click here

Congrats to Neil Moore – **NINE TIME** CCIE & CCDE!

Congratulations to Neil Moore on passing the CCDE Practical Exam this week, and becoming a NONTUPLE (9x) CCIE & CCDE!

Neil was a student in both my CCIE Data Center Bootcamp and CCDE Bootcamp within the past few years, and is truly an inspiration to us all. Neil’s brother Kelly is also a CCIE in Data Center. Neil likes to introduce himself and his brother to people at Cisco Live that they have 9 CCIEs between the two of them! ;) This year Neil gets to bump that up to 10 CCIEs and CCDE between the two of them!

Neil for sure will win the longest badge this year at Cisco Live 2016 Las Vegas!

Neil currently works for VMWare as an NSX Systems Engineer, is a VMware Certified Implementation Expert — Network Virtualization (VCIX-NV), and has plans to pursue the VMware Certified Design Expert (VCDX).

Congrats Neil!

Technology betrays everyone

Kelly Jackson Higgins has a story about how I hacked her 10 years ago, by sniffing her email password via WiFi and displaying it on screen. It wasn't her fault -- it was technology's fault. Sooner or later, it will betray you.

The same thing happened to me at CanSecWest around the year 2001, for pretty much exactly the same reasons. I think it was HD Moore who sniffed my email password. The thing is, I'm an expert, who writes tools that sniff these passwords, so it wasn't like I was an innocent party here. Instead, simply opening my laptop with Outlook running the background was enough for it to automatically connect to WiFi, then connect to a POP3 server across the Internet. I thought I was in control of the evil technology -- but this incident proved I wasn't.

By 2006, though, major email services were now supporting email wholly across SSL, so that this would no longer happen -- in theory. In practice, they still left the old non-encrypted ports open. Users could secure themselves, if they tried hard, but they usually weren't secured.

Today, in 2016, the situation is much better. If you use Yahoo! Mail Continue reading

Got privacy? If you use Twitter or a smartphone, maybe not so much

The notion of online privacy has been greatly diminished in recent years, and just this week two new studies confirm what to many minds is already a dismal picture.First, a study reported on Monday by Stanford University found that smartphone metadata -- information about calls and text messages, such as time and length -- can reveal a surprising amount of personal detail.To investigate their topic, the researchers built an Android app and used it to retrieve the metadata about previous calls and text messages -- the numbers, times, and lengths of communications -- from more than 800 volunteers’ smartphone logs. In total, participants provided records of more than 250,000 calls and 1.2 million texts.To read this article in full or to leave a comment, please click here

Microsoft releases ‘service pack 2’ for Windows 7

One of the most vexing aspects of a Windows 7 reinstall is that even after you install the operating system and Service Pack 1, you can expect to spend a ridiculous amount of time applying patches that came post-SP1. Service Pack 1 came out in 2011, and there have been dozens and dozens of fixes over the past five years.For the longest time, this was a sore spot among users. That and the fact that Microsoft was reluctant to issue a second service pack with just a rollup of current fixes.Well, that wish has been granted. The company today announced a "convenience rollup" for Windows 7 Service Pack 1 and Windows Server 2008 R2 that contains all of the security and non-security updates it has issued for the two operating systems since the Windows 7 Service Pack up through April 2016.To read this article in full or to leave a comment, please click here
