Network Outages Go Global

On August 30, CenturyLink experienced a major network outage that lasted for over five hours and disrupted CenturyLink customers nationwide as well as many other networks. What was unique about the outage was the scope of the disruptions as the outage affected video streaming services, game platforms, and even webcasts of European soccer. more

IoT From a Network Perspective: Learning to Navigate the New Realms

Let's play the analogy game. The Internet of Things (IoT) is probably going end up being like... a box of chocolates, because you never do know what you are going to get? a big bowl of spaghetti with a serious lack of meatballs? Whatever it is, the IoT should have network folks worried about security. Of course, there is the problem of IoT devices being attached to random places on the network, exfiltrating personal data back to a cloud server you don't know anything about. more

5G/F5G Cloud Announcements: NFV Game-Changing Confirmations

Over the past few days, Microsoft made two major announcements. One was a "playbook [for] providing a carrier-grade platform for edge and cloud computing to help network operators realize the full potential of 5G technology" using its it Azure cloud data centres. The second announcement was a new platform that enables satellite-based access to those same cloud data centres designated Azure Orbital. Coupled with these announcements was another one by Samsung... more

Your AI Strategy Canvas: Part 1

As the final project of my UC Berkeley School of Information course in Artificial Intelligence strategies, we had to submit an AI strategy canvas. Today, I will attempt to share important aspects of the canvas, so you and your team may have a template to work from and consider. Let's begin. We will look at both a strategy and operations perspective both internally and externally. Part one will include Internal and Operational Strategies, while Part II will examine external processes, threats, and procedures. more

Is the Internet Sustaining the Growth Trajectories Observed as the COVID-19 Pandemic Hit the World?

With the COVID-19 pandemic hitting the fifth month of global disruption, many companies have readily shared data, statistics and observational insights on how the pandemic has impacted the global data infrastructure. At DE-CIX, we quickly observed core Internet infrastructure demand increasing and readily reported this data in April of 2020. Microsoft's CEO Satya Nadella remarked to DatacenterDynamics in April of 2020 "we have seen two years' worth of digital transformation in two months." more

Internet of Things Requires a Rethink of Business Models

There certainly is a lot of interest in machine-to-machine communication (M2M) and the Internet of Things (IoT). But what we are seeing is only what is happening on the surface. Most of the M2M activities are taking place unnoticed. For example, most newly produced electronic devices are now all M2M enabled. Over 100 million smart meters have already been deployed by the electricity industry, with literally hundreds of millions of them in the pipeline. Healthcare is another key industry. more

Evolving the Internet Through COVID-19 and Beyond

As we approach four months since the WHO declared COVID-19 to be a pandemic, and with lockdowns and other restrictions continuing in much of the world, it is worth reflecting on how the Internet has coped with the changes in its use, and on what lessons we can learn from these for the future of the network. The people and companies that build and operate the Internet are always planning for more growth in Internet traffic. more

Verisign Expands MANRS Relationship to Strengthen Global Routing Security

Verisign has been involved with an initiative known as Mutually Agreed Norms for Routing Security, or MANRS, since its inception. MANRS, which is coordinated by the Internet Society, focuses on strengthening the security and resiliency of IP networks throughout the world by identifying and providing best practices for mitigating common routing security threats. MANRS began as a collaboration among network operators and internet exchange providers, with Verisign formally becoming a participant in its Network Operator Program in 2017. more

A DNS View of Lockdown

At NANOG 79 earlier this month Craig Labowitz from Nokia Deepfield presented on the impact on the COVID-19 pandemic on Internet use. The approach to the analysis used real-time streaming telemetry from Communication Service Provider (CSP) backbone and aggregation routers, and the data analysis covered content provider networks in North America, Europe and parts of Asia. more

Putting COVID-19 Traffic Growth Into Perspective

Nokia Deepfield is another company that works in the background on the web, and that analyzes data traffic patterns for the big ISPs. Their June 4 report on web traffic reports about the same thing we're hearing from most large ISPs -- the volume of web traffic suddenly shot up since the onset of the pandemic. Nokia Deepfield says that the increase in traffic has settled in at about a 25% increase over pre-COVID levels. more

Technology Adoption in the Internet

How are new technologies adopted in the Internet? What drives adoption? What impedes adoption? These were the questions posed at a panel session at the recent EuroDiG workshop in June. In many ways, this is an uncomfortable question for the Internet, given the Internet's uncontrolled runaway success in its first two decades. The IPv4 Internet was deployed about as quickly as capital, expertise, and resources could be bought to bear on the problem... more

Emerging Communications Technologies

A "New IP" framework was proposed to the ITU last year. This framework envisages a resurgence of a network-centric view of communications architectures where network-managed control mechanisms moderate application behaviors. It's not the first time that we've seen proposals to rethink the underlying architecture of the Internet's technology (for example, there were the "Clean Slate" efforts in the US research community a decade or so ago) and it certainly won't be the last. more

Help Science Fight COVID-19

Many organizations and individuals are socially committed and voluntarily help the weak, the poor, and the sick. Others consider how they can contribute. Supporting organizations and individuals by starting an aid project, donating money, or providing human resources, can make a crucial difference. The corona crisis is a challenge for many, if not all. Scientists around the world are experimenting with cures and vaccines, and they need help. However, you don't have to be a virologist to help science fight COVID-19. more

What COVID-19 Means for Network Security

The COVID-19 Pandemic is causing huge social and financial shifts, but so far, its impact on network security has gone under-reported. Yet with thousands of companies worldwide requiring millions of employees to work remotely, network administrators are seeing unprecedented changes in the ways that clients are using their networks and new threats that seek to leverage the current crisis. more

Predictions for a Post-COVID-19 World

While it might still be too early to make predictions, there are dozens of articles on the web predicting how the COVID-19 pandemic might change our long-term behavior. Here are some of the more interesting predictions I've seen that involve broadband and telecom... Millions of people were sent home for work or school to homes that didn't have good broadband. These folks have been telling the world for years that they don't have good broadband... more
