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

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

Cloudflare outage caused by bad software deploy (updated)

This is a short placeholder blog and will be replaced with a full post-mortem and disclosure of what happened today.

For about 30 minutes today, visitors to Cloudflare sites received 502 errors caused by a massive spike in CPU utilization on our network. This CPU spike was caused by a bad software deploy that was rolled back. Once rolled back the service returned to normal operation and all domains using Cloudflare returned to normal traffic levels.

This was not an attack (as some have speculated) and we are incredibly sorry that this incident occurred. Internal teams are meeting as I write performing a full post-mortem to understand how this occurred and how we prevent this from ever occurring again.

Update at 2009 UTC:

Starting at 1342 UTC today we experienced a global outage across our network that resulted in visitors to Cloudflare-proxied domains being shown 502 errors (“Bad Gateway”). The cause of this outage was deployment of a single misconfigured rule within the Cloudflare Web Application Firewall (WAF) during a routine deployment of new Cloudflare WAF Managed rules.

The intent of these new rules was to improve the blocking of inline JavaScript that is used in attacks. These rules were Continue reading

Transparency, Fairness, and Respect: The Policy Brief on Responsible Data Handling

It’s been a little over a year since the European Union’s General Data Protection Regulation (GDPR) was implemented, but almost immediately, people noticed its impact. First, there was the flurry of emails seeking users’ consent to the collection and use of their data. Since then, there’s also been an increase in the number of sites that invite the user to consent to tracking by clicking “Yes to everything,” or to reject them by going through a laborious process of clicking “No” for each individual category. (Though some non-EU sites simply broadcast “if we think you’re visiting from the EU, we can’t let you access our content.”) There was also the headline-grabbing €50 million fine imposed on Google by the French supervisory authority.

In its summary of the year, the EU Data Protection Board (EDPB) reported an increase in the number of complaints received under GDPR, compared to the previous year, and a “perceived rise in awareness about data protection rights among individuals.” Users are more informed and want more control over the collection and use of their personal data.

They’re probably irritated by the current crop of consent panels, and either ignore, bypass, or click through them Continue reading

BrandPost: “Shift Left” to Push Customer Support into Overdrive

The “Shift Left” concept is all about efficiency and quality. In software development, shifting left means performing testing early and often in the project lifecycle instead of waiting until the end. By discovering and addressing errors and bugs earlier, teams can ultimately deliver a higher quality product, one that is better aligned with addressing customers’ needs.In support, it means shifting requests as close to the customer as possible – which includes offering the ability self-serve. Moving solutions closer to the operational frontline and to the point of the first issue allows customers get answers quicker and organizations to close tickets faster. There are 3 big benefits of taking this approach:To read this article in full, please click here

BrandPost: SD-WAN Buyers Should Think Application Performance as well as Resiliency

As an industry analyst, not since the days of WAN Optimization have I seen a technology gain as much interest as I am seeing with SD-WANs today. Although full deployments are still limited, nearly every network manager, and often many IT leaders I talk to, are interested in it. The reason for this is two-fold – the WAN has grown in importance for cloud-first enterprises and is badly in need of an overhaul. This hasn’t gone unnoticed by the vendor community as there has been an explosion of companies bringing a broad range of SD-WAN offerings to market. The great news for buyers is that there is no shortage of choices. The bad news is there are too many choices and making the right decision difficult.To read this article in full, please click here
