Licenses for 5G service provider auction winners approved by FCC

The winners of a critical FCC auction for midband spectrum that ended last November have received their official grants of license to use the airwaves for which they spent a total of $22.4 billion, the FCC announced Wednesday.A total of 4,041 licenses were issued to 23 different bidders, according to the commission. Licensees hoping to use the spectrum for 5G rollouts still have to reimburse incumbent non-federal users of the band, which had been in use for radiolocation purposes, and the FCC said that further details about those costs would be laid out in a subsequent filing.Auction 110 saw the government sell off 100MHz of spectrum in the midband — around the 3.45GHz range — divided into 10 10MHz blocks for each Partial Economic Area or PEA that the FCC adopted in 2014. (There are 416 PEAs covering the US, meaning that 119 specific licenses were not sold in the auction.)To read this article in full, please click here

Tracking shifts in Internet connectivity in Kherson, Ukraine

Tracking shifts in Internet connectivity in Kherson, Ukraine

The Internet is not only a human right according to the United Nations, and a way to get information, but it has also become an important element in geopolitical conflicts, like the war going on in Ukraine. We have previously written about Ukrainians moving westward to escape the war and Internet outages in the country, but also about the importance of the open Internet in Russia.

Over this past week, we observed an outage in the occupied city of Kherson, south Ukraine, coupled with an apparent shift in who controls the Internet within the region. First, let’s give some context and show what we saw.

The Russian-occupied Kherson (a city of 280,000 people) experienced an Internet outage on Saturday, April 30, 2022, that began just after 16:00 UTC. The outage lasted until Wednesday, May 4, with traffic starting to return around 04:30 UTC traffic.

Tracking shifts in Internet connectivity in Kherson, Ukraine

In the chart below, we can see that there was a 43% decrease in traffic from Kherson from February 23 to 24, after the war started. However, this weekend’s outage is the most significant disruption to Internet traffic in Kherson since the start of the war.

The case for declarative network automation

Nemertes recently looked at how organizations with larger networks—specifically Cisco-heavy networks—implemented network automation. The results were a bit surprising in that less than 20% use Cisco’s flagship DNA Center network controller and management dashboard that can automate provisioning and change management.On the other hand more than 40% roll their own automation solution using various forms of imperative scripting or programming (mostly Python), and about 50% engage a different model instead of or in addition: declarative automation.To read this article in full, please click here

Using strace and ltrace to help with troubleshooting on Linux

Both strace and ltrace are powerful command-line tools for debugging and troubleshooting programs on Linux: Strace captures and records all system calls made by a process as well as the signals received, while ltrace does the same for library calls.If a program acts differently than you expect, you can use these tools to see “behind the curtain” and maybe get some clues as to what is going on. [ Get regularly scheduled insights by signing up for Network World newsletters. ] Be forewarned, though. When you use either of these commands, you will end up with a lot of output to look through. Still, that can tell you quite a bit about how a process is working and sometimes give you important insights.To read this article in full, please click here
