Member News: Internet Society Highlights from 2019

It’s been a busy year for Internet Society Chapters around the world, with members pushing to extend Internet connections to remote areas, involved in public policy, and focusing on cybersecurity. Here are some of the highlights in 2019:

Extending Internet connections

Community awareness: The Madagascar chapter provided awareness training on community-based broadband networks in the rural areas of Ambohimasina, Antambolo, and Morarano-Antongona during February and March. “Our main objective was to ensure that people using the Internet continue to be convinced of its usefulness,” the Chapter wrote. Another goal was for local leaders to have access to the Internet for the “purposes of innovation, creativity and economic opportunities for their municipality.”

Network planning: In Nigeria, the Internet Society Chapter began planning to set up a community network in Zaria, a city in the northern region of the country. The Internet Society provided startup funds of about 10 million naira, or “about the cost of a fairly used Toyota Corolla,” the Chapter noted. “By being very frugal and leveraging on existing infrastructure being contributed by community members, this will cover the cost of the initial wireless hardware required to connect at least 12 locations across Zaria.”

Adopting a new approach to HTTP prioritization

Adopting a new approach to HTTP prioritization
Adopting a new approach to HTTP prioritization

Friday the 13th is a lucky day for Cloudflare for many reasons. On December 13, 2019 Tommy Pauly, co-chair of the IETF HTTP Working Group, announced the adoption of the "Extensible Prioritization Scheme for HTTP" - a new approach to HTTP prioritization.

Web pages are made up of many resources that must be downloaded before they can be presented to the user. The role of HTTP prioritization is to load the right bytes at the right time in order to achieve the best performance. This is a collaborative process between client and server, a client sends priority signals that the server can use to schedule the delivery of response data. In HTTP/1.1 the signal is basic, clients order requests smartly across a pool of about 6 connections. In HTTP/2 a single connection is used and clients send a signal per request, as a frame, which describes the relative dependency and weighting of the response. HTTP/3 tried to use the same approach but dependencies don't work well when signals can be delivered out of order.

HTTP/3 is being standardised as part of the QUIC effort. As a Working Group (WG) we've been trying to fix the problems that non-deterministic ordering Continue reading

New Year, New Adventure

I’ll skip the build-up and jump straight to the whole point of this post: a once-in-a-lifetime opportunity has come up and I’m embarking on a new adventure starting in early 2020. No, I’m not changing jobs…but I am changing time zones.

Sometime in the next month or two (dates are still being finalized), I’ll be temporarily relocating to Tokyo, Japan, to help build out VMware’s Cloud Native Field Engineering team to provide consulting and professional services around cloud-native technologies and modern application platforms for customers in Japan. Basically, my charter is to replicate the former Heptio Field Engineering team (now the Cloud Native Field Engineering Practice within VMware) in Japan.

Accomplishing this feat will involve a variety of responsibilities: a pretty fair amount of training/enablement, engaging customers on the pre-sales side, helping lead projects on the post-sales (delivery) side, mentoring team members, performing some project management, probably some people management, and the infamous “other duties as required.” All in about six months (the inital duration of my assignment), and all while learning Japanese! No big deal, right?

I’m both simultaneously excited and scared. I’m excited by the idea of living in Tokyo, but let’s be honest—the language barrier is Continue reading

The Week in Internet News: Worries of a Fragmenting Internet

Fragments: Some activists are raising concerns about a fragmented Internet, with two University of Southampton professors writing about four competing versions of the Internet in Wired. The two professors wrote about the same issues for the World Economic Forum earlier this year. The vision of a coordinated, global network “might change in 2020 as Internet governance will be at the centre of a number of ongoing debates coming to the fore,” they wrote. “What values should the technology support? How should it deal with free speech and association? What about privacy?”

Squirrels on wheels: Mont Belvieu, a city near Houston, Texas, has built its own broadband network after struggling with slow speeds from existing providers, the Dallas Morning News reports. “I believe squirrels run on a wheel for my Internet,” one resident half-joked on a city survey. About half of the city’s households have signed up for the service, offering speeds of up to 1 gigabit per second for $75 a month, since it launched in mid-2018.

Network Automation and the Lack of Innovation in the Management Plane

Chris Wade Chris Wade serves as the co-founder and CTO of Itential, a network automation software company focused on simplifying and accelerating the adoption of network automation and transforming network operations practices. There has been tremendous innovation in IT infrastructure with the adoption of cloud-scale architecture and a migration towards modern applications. In contrast, Enterprise networking has been viewed over the last 30 years primarily for moving data between client-server applications. This basic premise along with consumer devices drove innovation in the network domain to prioritize “speeds and feeds” as the primary objective for networking vendors. Even with the adoption of cloud-scale infrastructure, most adoption meant a migration from current data centers to cloud platforms for IaaS (Infrastructure as a Service) which didn’t dramatically impact networking requirements. For some context on network innovation, it is important to break network devices into their logical components. A simplified view of networks separates general functionality into three primary components: Data Plane — Movement of packets or network data between network elements Control Plane — Decision logic of where to send network data on the data plane Management Plane — Interfaces that allow users & external systems to modify the behavior of the network.

So that tweet was misunderstood

I'm currently experiencing the toxic hell that is a misunderstood tweet going viral. It's a property of the social media. The more they can deliberately misunderstand you, the more they can justify the toxicity of their response. Unfortunately, I had to delete it in order to stop all the toxic crud and threats of violence.

The context is how politicians distort everything. It's like whenever they talk about sea level rise, it's always about some city like Miami or New Orleans that is sinking into the ocean already, even without global warming's help. Pointing this out isn't a denial of global warming, it's pointing out how we can't talk about the issue without exaggeration. Mankind's carbon emissions are indeed causing sea level to rise, but we should be talking about how this affects average cities, not dramatizing the issue with the worst cases.

The same it true of health care. It's a flawed system that needs change. But we don't discuss the people making the best of all bad choices. Instead, we cherry pick those who made the worst possible choice, and then blame the entire bad outcome on the system.

My tweet is in response to this Elizabeth Warren Continue reading
