A New Voice Joins the Chorus: Welcome to the Colombia Chapter!
A new Internet Society Chapter has been founded within the Regional Bureau in Latin America & Caribbean. The creation of the Colombia Chapter is today officially announced at Universidad del Rosario, in Bogotá.
Our desire is to extend a gracious and inclusive welcome to all the 67 founding members that have been active members of the Internet Society for several years, and to the ones that have recently joined the community to be part of the Chapter.
The Chapter invites you to join the live broadcasting starting at 8:00 AM (UTC-5) with eminent guests speakers such as Juanita Rodriguez Kattah, Former Vice Minister of Digital Economy, Hugo Sin Triana, Director of Innovation in Info Projects, Valérie Gauthier, Director of the Department of Applied Mathematics and Computer Science (MACC) at the University of Rosario, Nancy Quiros, the Internet Society’s Chapter Development Manager for Latin America and Caribbean Region, and Javier Pinzon, Member of the Colombian Internet Governance Forum.
The large attendance (approximately 120 participants) at the launching event, speaks to the need for a Chapter to join the Colombian community’s efforts to ensure an open, globally connected, trustworthy and secure Internet for everyone.
The Chapter will encourage the Continue reading
Video: What Problem Are We Solving with SDDC?
Remember the Software-Defined Data Centers hype? While I covered SDDC concepts and technologies for years in my webinars and workshops, I never created an introductory webinar on the topic.
That omission has been fixed in late August – SDDC 101 webinar is available as part of free subscription, and as always I started with the seemingly simple question: What problem are we trying to solve?
Intelligent Network, Intelligent Operator
Maybe I’m old school, but I’m just not into black box networking. Especially if critical services are dependent on my network infrastructure. I wore those shoes for 19 years, so this feeling has burned into my psyche through many real world experiences. I don’t think I’m alone in this thinking.When bad things happen to network users, all eyes are on the physical network team, even when it’s not a physical network problem. The physical network is guilty until it can be proven otherwise. So it’s only fair that physical network operators are skeptical of technology whose inner workings are unknowable. Waiting on your network vendor’s technical support team isn’t an option when the CIO is breathing down your neck. Especially if a mitigation exists that can be acted on immediately.
That said, there is indeed a limit to the human ability. It is increasingly lossy as the number of data points grow. Moreover, the levels of ability are inconsistent across individuals. Box level operations leaves it up to the operator to conceptualize the physical network state as a whole in his/her head and this generally results in Continue reading
VMware CEO Lists Top 3 Priorities for 2019: NSX, Cloud, and Containers
“Obviously I love my vSAN child. It’s not as important as my NSX child,” VMware CEO Pat Gelsinger said, referring to VMware’s software-defined storage and networking platform, respectively.
Thought: Face-to-face is effective, No One Talks About How much it costs
This HBR article from April 2017 highlights a researcher talking about their paper that face-to-face is more effective than email. Well, duh. However, prior to making their requests, we asked participants in each condition to predict how many of the 10 strangers they asked would agree to fill out the survey. Participants in the face-to-face […]

Kindergarten Tech Cop: The Job I Never Wanted
This month, we’ve asked parents to share their experiences of raising kids in the tech age. Today’s guest author is Sara Given, creator of the viral blog “It’s Like They Know Us,” which skewers the myth of the perfect parent. She’s also the author of Parenting Is Easy: You’re Probably Just Doing It Wrong.
“Mom, what’s your passcode?”
I looked up to find my 5-year-old daughter jabbing her finger at my iPhone screen. She continued, “My school iPad has a passcode. What’s yours? I need to take pictures of the cat.”
This was a tame request compared to her other inquiries, (“Can I have a little brother?”), but it bothered me for two reasons: First, I knew that if I gave her that passcode, she would immediately take 5,000 pictures of the floor. And second, I hadn’t considered that at age 5 she’d already be so immersed in technology. That she’d know the lingo. That she probably already had more Instagram followers than me. #floorpics
While my daughter chattered away about the cartoon-character math app she’d been using in class, I found myself facing a dilemma: I want to limit my child’s exposure to Continue reading
Ericsson and Telia Switch On Live 5G Network as Key Testbed in Sweden
Swedish carrier Telia Company is the latest carrier to announce it has switched on a 5G network, with the help of Ericsson of course.
IPFire on Raspberry Pi 3B
IPFire is a modular opensource firewall distribution with a primary objective of security. IPFire employs a Stateful Packet Inspection (SPI) firewall, which is built on top of netfilter (the Linux packet filtering framework). The modular designs allows to extend basic functionality by installation of add-ons that can be easily deployed with the IPFire package management system - pakfire. Updates are digitally signed and encrypted.
During the installation of IPFire, the network is configured into different, separate segments (zones). These different segments may be enabled separately, depending on your requirements. Each segment represents a group of computers who share a common security level.
Green represents a "safe" area. This is where all regular clients will reside. It is usually comprised of a wired, local network. Clients on Green can access all other network segments without restriction. Red indicates "danger" or the connection to the Internet. Nothing from Red is permitted to pass through the firewall unless specifically configured by the administrator. Blue represents the "wireless" part of the local network. Since the wireless network has the potential for abuse, it is uniquely identified and specific rules govern clients on it. Clients on this network segment must be explicitly allowed Continue reading
Google Relies on SDN, But Worries About the End of Moore’s Law
Google's compute infrastructure is straining to keep up with data demands. The company is looking for "novel ways" to do more data processing. That might include cluster computing.
Research: BGP Routers and Parrots
The BGP specification suggests implementations should have three tables: the adj-rib-in, the loc-rib, and the adj-rib-out. The first of these three tables should contain the routes (NLRIs and attributes) transmitted by each of the speaker’s peers. The second table should contain the calculated best paths; these are the routes that will be (or are) installed in the local routing table and used to build a forwarding table. The third table contains the routes which have been sent to each peering speaker. Why three tables? Routing protocols standards are (sometimes—not always) written to provide the maximum clarity to how the protocol works to someone who is writing an implementation. Not every table or process described in the specification is implemented, or implemented the way it is described.
What happens when you implement things in a different way than the specification describes? In the case of BGP and the three RIBs, you can get duplicated BGP updates. What do parrots and BGP have in common describes two situations where the lack of a adj-rib-out can cause duplicate BGP updates to be sent.
