Myanmar’s March Towards a Digital Future

Earlier this month, in collaboration with the Asia-Pacific Telecommunity (APT) and the Government of the Republic of the Union of Myanmar, we delivered a training program on Internet Governance for 32 government officials in Myanmar’s capital city, Naypyidaw.

The program ran over three days covering various topics such as Internet policy principles and regulatory frameworks, Internet infrastructure and standards, Internet for development, and cybersecurity.

What impressed me was the participants’ interest in asking questions and their active participation in discussions – it was obvious they were all very eager to learn and explore ways they could apply the learnings in their roles in the various departments they were from. We also got to discuss and see what promise digital technology holds for the country.

I have had the opportunity to visit Myanmar several times, including well before the democratic reforms began. In the few years since those reforms brought Myanmar to the world stage, the country has gone through tremendous transformation. I distinctly remember the difficulties in getting access to the Internet and the lack of mobile phones during my earlier visits.

Today, it’s a very different story. There are multiple service providers, and multiple cable landing stations that provide Continue reading

What Happens When The Internet Breaks?

It’s a crazy idea to think that a network built to be completely decentralized and resilient can be so easily knocked offline in a matter of minutes. But that basically happened twice in the past couple of weeks. CloudFlare is a service provide that offers to sit in front of your website and provide all kinds of important services. They can prevent smaller sites from being knocked offline by an influx of traffic. They can provide security and DNS services for you. They’re quickly becoming an indispensable part of the way the Internet functions. And what happens when we all start to rely on one service too much?

Bad BGP Behavior

The first outage on June 24, 2019 wasn’t the fault of CloudFlare. A small service provider in Pennsylvania decided to use a BGP Optimizer from Noction to do some route optimization inside their autonomous system (AS). That in and of itself shouldn’t have caused a problem. At least, not until someone leaked those routes to the greater internet.

It was a comedy of errors. The provider in question announced their more specific routes to an upstream customer, who in turn announced them to Verizon. After that all bets are Continue reading

In Patagonia: A New Community Network in the Village of El Cuy

Patagonia, a region in Argentina made up of deserts, pampas, and grasslands, is known for its large areas of uninhabited territory. In the north sits the village of El Cuy, with just 400 residents. Far from the large urban centers, the people of El Cuy have adapted to the difficulties of accessing different services and technologies. The Internet is no exception, thanks to a new community network.

In several ways, the community network model represents the Internet model of networking come to life. Community networks are built and implemented by people, through collaboration – all stages of the process include the community working together. In the case of the El Cuy community network, support was also provided by the CABASE and the ENACOM.

For Christian O’Flaherty, the Internet Society’s senior development manager for Latin America and the Caribbean, Internet access has become a positive catalyst for community development. “The operation of this pilot program has motivated the residents to organize themselves into a cooperative. This step will allow inhabitants from El Cuy to have access to various fundings offered by actors such as ENACOM to increase the capacity of the Internet connection.”

Becoming Broadband Ready Means Community Innovation and Collaboration

There are countless communities across North America that are hungry to see better broadband access for their residents. It’s clear to local leaders that high-quality Internet access is the bedrock of a healthy and successful community – providing job opportunities, bolstering education, transforming health care, and democratizing access to information. What isn’t always so clear is how to make it happen.

That’s why Next Century Cities teamed up with the Internet Society and Neighborly to create the Becoming Broadband Ready toolkit. This comprehensive toolkit provides local leaders with a roadmap to encourage broadband investment in their community.

While every community will choose to tackle connectivity a little differently – a small island community and a large urban center will likely have unique considerations and approaches – there are many common threads that run through successful broadband projects. Becoming Broadband Ready compiles these threads into an easy-to-use and impactful resource for any community, providing resources specific to:

  • Establish Leadership
  • Build a Community Movement
  • Identify Goals
  • Evaluate the Current Circumstance
  • Establish Policies and Procedures to Support Investment
  • Prioritize Digital Inclusion
  • Identify Legislative and Regulatory Barriers
  • Explore Connectivity Options
  • Explore Financing Options
  • Be a Clear Collaborator
  • Measure Success

Next Century Cities identified the Continue reading

Campus design feature set-up : Part 5

In this blog series, we’ve been on a journey of sorts. We’ve shown you all the different ways to set up the CL 3.7.5 campus feature: Multi-Domain Authentication in this 6-part series and guess what? We’re getting into the home stretch!

In blogs 1-4 we had guides for Wired 802.1x using Aruba ClearPass, Wired MAC Authentication using Aruba ClearPass, Multi-Domain Authentication using Aruba ClearPass and Wired 802.1x using Cisco ISE. After this blog, we’ll just have one more covering. Multi-Domain Authentication using Cisco ISE. But we’re not here to talk about those now.

In this fifth guide, I’ll be sharing how to enable Wired MAC Authentication in Cumulus Linux 3.7.5+ using Cisco ISE (Identity Services Engine) 2.4, Patch 8.

Keep in mind that this step-by-step guide assumes that you have already performed an initial setup of Cisco ISE .

Cisco ISE Configuration:

1. Add a Cumulus Switch group to Cisco ISE:

First, we are going to add a Network Device Group to Cisco ISE:

Administration > Network Resources > Network Device Groups. Click the “+Add” button

Make sure to set the “Parent Group” to “All Device Types.” The result will look Continue reading

Internet Society Asia-Pacific Policy Survey 2019 Now Open: Consolidation in the Internet Economy

The Internet Society recently embarked on a year-long effort to explore the trends of consolidation in the Internet economy, and I write to sincerely invite you to share your views with us in the Regional Policy Survey 2019, an annual exercise of the Asia-Pacific Bureau of the Internet Society.

Your input is very important to us. It will help us understand the issue from your perspectives and produce a report to be released later this year. Ultimately, your input will help us come up with technical and policy recommendations for policymakers with the aim of preserving the Internet’s properties that give us the critical abilities to connect, speak, innovate, share, choose, and trust.

Please take 5-10 minutes to complete the survey, which covers all Internet users in Asia-Pacific. To show our appreciation, we will be offering 2 tablet computers in a lucky draw, and the winners will be notified by email after the survey closes on July 31.

An eco-friendly internet of disposable things is coming

Get ready for a future of disposable of internet of things (IoT) devices, one that will mean everything is connected to networks. It will be particularly useful in logistics, being used in single-use plastics in retail packaging and throw-away shippers’ carboard boxes.How it will happen? The answer is when non-hazardous, disposable bio-batteries make it possible. And that moment might be approaching. Researchers say they’re closer to commercializing a bacteria-powered miniature battery that they say will propel the IoDT.[ Learn more: Download a PDF bundle of five essential articles about IoT in the enterprise ] The “internet of disposable things is a new paradigm for the rapid evolution of wireless sensor networks,” says Seokheun Choi, an associate professor at Binghamton University, in an article on the school’s website.To read this article in full, please click here

Understanding RTs and RDs

One of the items that continues to come up in my conversations with folks learning about about MPLS VPNs is defining what a Route Target (RT) and Route Distinguisher (RD) are. More specifically, most seem to understand their purpose – but often times they don’t quite understand the application. I (and many others – just google “Understanding RDs and RTs”) have written about this in the past but Im hoping to put a finer point on the topic in this post.

If someone were to ask me to summarize what route targets and route distinguishers were – I’d probably define them like this…

Route Distinguishers – serve to make routes unique
Route Targets – metadata used to make route import decisions

Now – I’ll grant that those definitions are awfully terse, but I also feel like this is a topic that is often over complicated. So let’s spend some time talking about RTs and RDs separately and then bring it all together in a lab so you can see what’s really happening.

Route Distinguishers

As I said, a route distinguisher serve to make routes look unique. So why do we care about making routes look unique? I’d argue one of Continue reading
