Network management

Despite some problems, the Internet overall is handling unprecedented surges of demand as it keeps a fractured world connected at a time of global catastrophe. The Internet, born as a Pentagon project during the chillier years of the Cold War, has taken such a central role in 21st Century civilian society, culture and business that few pause any longer to appreciate its wonders — except perhaps, as in the past few weeks, when it becomes even more central to our lives. “Resiliency and redundancy are very much a part of the Internet design,” explained Internet pioneer Vinton Cerf, whose passi

As the nation prepares to ride out a pandemic that will persist for months, the need is acute for fast and inexpensive broadband rollout. It’s important to know that you have options to deploy new facilities – options that can be exercised in days or weeks, not years. Last week, we shared some ideas for using fiber, mmWave, and Wi-Fi to get services to the unserved.

Between Jan 29 (shortly after COVID-19 appeared in the US) and March 26 there was a 105% spike in people active online at home between 9:00 am and 6:00 pm. So why hasn’t the internet ground to a halt? The answer lies in the lessons of Mother’s Day and freeway traffic jams.

Federal Communications Commission Chairman Ajit Pai spoke April 1 with broadband and telephone service providers and trade association leaders about the state of American communications networks as volume and usage patterns shift during the coronavirus pandemic. The Chairman heard from providers across the country who reported network usage had risen about 20-35% for fixed networks and 10-20% for cellular networks in recent weeks, with increased demand in suburban, exurban, and residential areas and during daytime hours.

We debut a tool that will allow the public and policymakers to track the growth in traffic during the pandemic and get a weekly snapshot of how cable broadband networks are performing during the pandemic.

Everything from meetings at the office to happy hours with friends are all now occurring in digital space. All of this internet use is putting more pressure on our broadband infrastructure. Just in the past few weeks, data demands have risen in nearly all categories.

With Comcast's network performing so well during the pandemic, why did Comcast's data cap exist in the first place? The answer has always been "money," of course—a Comcast executive once acknowledged in a Twitter reply that imposing data caps is a business decision, not one driven by technical necessity.

As the social distancing efforts push everything from school to socializing into video chat, networks have seen huge surges in traffic — and new anxieties over how digital networks will stand up under the strain. So far, both carriers and the Federal Communications Commission insist that the country’s networks are capable of bearing the strain, particularly given the voluntary throttling instituted by many of the most bandwidth-heavy services.

The many changes caused by the COVID-19 pandemic have given the world’s communications networks an impromptu stress test. Data demand has surged and shifted. “Peak hour” — the busiest period of the day on a network — now hits at different times and extends for longer durations. Signs of stress have shown up in other parts of the world so Americans have begun asking: Do our networks have the capacity to meet this surge in demand? Here’s the bottom line.

As so many Americans work from home, as our schoolchildren and university students shift to online learning, as virtually all of our social interactions occur online, a fundamental question looms: Will the internet break? The answer is probably not a simple yes or no, and it’s probably not the same answer everywhere in the United States.
