More Girls in ICT: The Internet Society Signs MoU with the Mexican Government

Women and girls are significantly less likely to choose ICT (Information and Communication Technology) studies than men. There are many reasons for this. Barriers to access, but also retention in ICT studies are complex as they are often related not only to economic but also to social and cultural barriers.

A lot of initiatives are being developed worldwide to break these barriers, and at the Internet Society we believe that only if we join efforts we can overcome them and help to close the digital gender gap.

For this reason, on July 19, the Internet Society and the Secretariat of Communications and Transport of the Mexican government signed a cooperation agreement to support the “Women in STEM, Future Leaders” project.

In Mexico only 35.5% of tertiary graduates in ICT are women. The initiative aims to change these numbers. It provides training and support to young women from public high schools with the purpose of encouraging them to pursue a career in science and ICT.

The program, launched at the beginning of 2018 in coordination with the U.S.-Mexico Foundation, has already reached more than 180 girls from all over the country. It is working closely with 32 Mexican Connected Points (Puntos Mexico Conectados), which are centers that provide Internet access and training to Continue reading

Awaiting IBM’s Power Systems Growth Spurt

Given the rollout of the “ZZ” and “Boston” variants of its Power9 systems, which are aimed at customers who are building clusters and at midrange enterprises that use a Power System server as their main back-end system, you might be expecting for the Power Systems line at IBM to have had a big bump in the second quarter of this year. …

Steven G. Huter – The 2018 Jonathan B. Postel Service Award Winner

With so many moving parts to advancing Internet access and enabling communities to reach the rest of the world, the biggest key to success, according to this year’s Jonathan B. Postel Award winner, is listening.

Steven Huter listens. He says it’s his most important job. The Director for the Network Startup Resource Center (NSRC) and a Research Associate at the University of Oregon says before configuring community networks and setting Internet development goals, his organization has to make sure they are solving the right problems.

“Listening first to what local Internet developers request and desire in terms of assistance, based on their respective conditions and challenges, is vital for a successful outcome,” Huter says.

Only half the people in the world have Internet access, and the NSRC works on creating “a sustainable community of Internet-savvy engineers and local operators that can enable continuous progress in their countries to bring more affordable Internet access and better network performance for their respective communities.”

Essentially, they go to areas in need, help set up the hardware and digital necessities for Internet access, and train local operators and system workers to handle that network independently. And Huter has been an integral part Continue reading

Site Reliability Engineering at the Network Collective

The Site Reliability Engineer (SRE) role often seems a bit mysterious to folks working at smaller and mid-sized companies, where the team isn’t large enough to separate into SRE, operations, and other teams. What does and SRE do, and how is it different from what the average network engineer does? In this Network Collective Off the Cuff, we sit with Michael Kehoe of LinkedIn to discuss the role of the SRE.

Cloning All Repositories in a GitHub Organization

I’ve recently started playing around with Ballerina, and upon the suggestion of some folks on Twitter wanted to clone down some of the “official” Ballerina GitHub repositories to provide code examples and guides that would assist in my learning. Upon attempting to do so, however, I found myself needing to clone down 39 different repositories (all under a single organization), and so I asked on Twitter if there was an easy way to do this. Here’s what I found.

Fairly quickly after I posted my tweet asking about a solution, a follower responded indicating that I should be able to get the list of repositories via the GitHub API. He was, of course, correct:

curl -s https://api.github.com/orgs/ballerina-guides/repos

This returns a list of the repositories in JSON format. Now, if you’ve been paying attention to my site, you know there’s a really handy way of parsing JSON data at the CLI (namely, the jq utility). However, to use jq, you need to know the overall structure of the data. What if you don’t know the structure?

No worries, this post outlines another tool—jid—that allows us to interactively explore the data. So, I ran:

IDG Contributor Network: Communications hubs emerge as a bridge to hybrid IT

Adoption of hybrid IT for delivery of applications across legacy enterprise data centers, and increasingly cloud SaaS and IaaS platforms, is rendering traditional network architectures obsolete. Numerous analysts and articles have predicted the coming obsolescence of hub and spoke MPLS networks anchored on legacy enterprise data centers. While few have detailed what to do about it, a growing number of enterprises are taking matters into their own hands. Those in the know are leveraging communication hubs, sometimes also referred to as cloud hubs, to bridge the gap between their legacy data center environments and the cloud.The growing challenge of SaaS application performance As enterprises accelerate their move to cloud, including the growing trend toward cloud office suites, such as Office 365 and Google Suite, where users expect LAN-like performance, challenges are mounting. According to Microsoft, Office 365 is growing at 43 percent, and as of the end of 2017 was boasting 120 million active users. A 2017 survey by TechValidate noted that despite increasing both firewall and network bandwidth capacity, nearly 70 percent of companies experienced weekly network-related performance issues after deploying Office 365. Gartner’s 2018 Strategic Roadmap for Networking, released earlier this year, noted that nearly all enterprises Continue reading

ExtremeXOS 22.5.1 adds support Broadcom ASIC table utilization statistics

ExtremeXOS 22.5.1 is now available! describes added support in sFlow for "New data structures to support reporting on hardware/table utilization statistics." The feature is available on Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X870, X620, X690 series switches.

Figure 1 shows the packet processing pipeline of a Broadcom ASIC. The pipeline consists of a number of linked hardware tables providing bridging, routing, access control list (ACL), and ECMP forwarding group functions. Operations teams need to be able to proactively monitor table utilizations in order to avoid performance problems associated with table exhaustion.

Broadcom's sFlow specification, sFlow Broadcom Switch ASIC Table Utilization Structures, leverages the industry standard sFlow protocol to offer scaleable, multi-vendor, network wide visibility into the utilization of these hardware tables.

The following output from the open source sflowtool command line utility shows the raw table measurements (this is in addition to the extensive set of measurements already exported via sFlow by ExtremeXOS):

Securing U.S. Democracy: Athenian Project Update

Securing U.S. Democracy: Athenian Project Update

Securing U.S. Democracy: Athenian Project Update
Last December, Cloudflare announced the Athenian Project to help protect U.S. state and local election websites from cyber attack.

Since then, the need to protect our electoral systems has become increasingly urgent. As described by Director of National Intelligence Dan Coats, the “digital infrastructure that serves this country is literally under attack.” Just last week, we learned new details about how state election systems were targeted for cyberattack during the 2016 election. The U.S. government’s indictment of twelve Russian military intelligence officers describes the scanning of state election-related websites for vulnerabilities and theft of personal information related to approximately 500,000 voters.

This direct attack on the U.S. election systems using common Internet vulnerabilities reinforces the need to ensure democratic institutions are protected from attack in the future. The Athenian Project is Cloudflare’s attempt to do our part to secure our democracy.

Engaging with Elections Officials

Since announcing the Athenian Project, we’ve talked to state, county, and municipal officials around the country about protecting their election and voter registration websites. Today, we’re proud to report that we have Athenian Project participants in 19 states, and are in talks with many more. We have also strategized with civil Continue reading
