The FCC’s latest spectrum policy announcement, which preserves 500MHz of the 12GHz band for satellite use while designating another 500MHz for terrestrial radios, is a recognition that satellite internet providers like Starlink are being heard, according to experts.

The commission’s latest notice of proposed rulemaking, posted May 18, reflects a more even-handed approach than has been adopted in the past. In carving up the airwaves for C-band usage, substantial amounts of spectrum were taken away from incumbent satellite users and handed off to terrestrial operators, most notably major telecom providers.

5G promises increased speed, lower latency, and support for a significantly larger number of connected devices. But the growth in devices and in new applications that will ensue also will expand the attack surface, offering new opportunities for malicious actors to take advantage of security gaps.

Plus, as with any new technology, there is a great deal of potential for misconfigurations, errors, and unpatched vulnerabilities while companies are still learning how to deploy and secure 5G at scale.

About 75% of communication service providers worldwide said that they had experienced up to six security breaches of 5G networks within the past year, according to a November 2022 survey by GlobalData and Nokia. Half of the respondents said that they experienced an attack that resulted in the leakage of customer data, and nearly three quarters said that an attack had caused a service outage.

For the third time in a row, Frontier is ranked number one among the world’s fastest supercomputers, and it remains the only whose fastest speed exceeds one exaFLOPS.

At 1.194 quintillion floating point operations per second (FLOPS), Frontier kept its ranking with more than double the top speed of its nearest competitor, according to the list compiled by TOP500, which issues the rankings twice a year. A quintillion is 10¹⁸ or one exaFLOPS (EFLOPS).

The number two machine, Fugaku, maxed out at 442.01petaFLOPS. A petaFLOPS is 10¹⁵ FLOPS.

Two competitors in the top 10 improved their speeds since the last ranking period that ended in November 2022, but not nearly enough to even draw close. Those two—LUMI and Leonardo—rank third and fourth, respectively.

When working in the Linux terminal window, you have a lot of options for moving on the Linux command line; backing up over a command you’ve just typed is only one of them.

Using the Backspace key

We likely all use the backspace key fairly often to fix typos. It can also make running a series of related commands easier. For example, you can type a command, press the up arrow key to redisplay it and then use the backspace key to back over and replace some of the characters to run a similar command. In the examples below, a single character is backed over and replaced.

The Department of Energy has awarded $40 million to 15 vendors and university labs as part of a government program that aims to reduce the portion of data centers' power usage that's used for cooling to just 5% of their total energy consumption.

The DOE's Advanced Research Projects Agency–Energy (ARPA-E) is providing the funding to jumpstart a program called COOLERCHIPS, an acronym for Cooling Operations Optimized for Leaps in Energy, Reliability, and Carbon Hyperefficiency for Information Processing Systems.

For chip cooling to account for just 5% of total energy consumption, that would translate to a PUE of 1.05. (Power usage effectiveness, or PUE, is a metric to measure data center efficiency. It’s the ratio of the total amount of energy used by a data center facility to the energy delivered to computing equipment.)

System memory is a complex problem. More memory means more performance, especially in a virtualized environment. But more memory also requires more power, and that can add up as you start to get into thousands of memory sticks.

Plus, you can only put so many memory sticks in a server, depending on the number of slots available. So how do you increase memory capacity? By increasing memory density on the chips, which is easier said than done. However, a startup called NEO Semiconductor is claiming it will be able to increase memory density by up to eight times over standard memory with a breakthrough 3D design.

It’s not a new concept; 3D memory stacking has been used in NAND flash to increase capacity for a decade now. Memory transistors can only be so large to fit in the confines of a DRAM chip. Rather than an increase the number of transistors laid out side by side, memory makers began stacking it on top of each other, thus increasing capacity in the same physical space. In the 10 years since 3D stacking began, NAND flash DRAM has reached the 170-layer mark, and SSDs have seen a significant increase in capacity without increasing the number of chips.

It’s important to back up your databases, but it’s even more important to be able to restore it, so once you’ve identified how you’re going to back it up, make sure you test the different recovery scenarios.

Broadly speaking, there are two database types considered here, traditional and modern, and  recovery is different for each. A traditional database in this context is a database that runs in a single server or virtual machine that you manage, and a modern database might run across many nodes or it might even be serverless, where you have no access to the underlying infrastructure.

Recovering traditional databases

Restoring a traditional database is straightforward as long as you have practiced how to handle  different things that could go wrong. You don’t want to test your backup system for the first time during an actual database outage.

The reliability of services delivered by ISPs, cloud providers and conferencing services (a.k.a. unified communications-as-a-service (UCaaS)) is an indication of how well served businesses are via the internet.

ThousandEyes is monitoring how these providers are handling the performance challenges they face. It will provide Network World a roundup of interesting events of the week in the delivery of these services, and Network World will provide a summary here. Stop back next week for another update, and see more details here.

As more IT organizations apply artificial intelligence (AI), machine learning (ML), and so-called AIOps technology to network management, network data is critical to success. AI/ML technology requires more and more data to learn individual networks, derive insights, and offer recommendations. Unfortunately, many organizations encounter problems when trying to feed network data to these AI tools.

In other words, network teams need to modernize their approach to network data before they embrace AI technology.

Enterprise Management Associates recently surveyed 250 IT professionals about their experience with AI/ML-driven network management solutions for a report, “AI-Driven Networks: Leveling up Network Management.” It found that data problems are the number-two technical challenge they encounter when applying AI/ML to network management. Only network complexity is a bigger technical issue.

Branch offices play a critical role in the success of a business, contributing significantly to its bottom line. Despite that, branch offices often do not have all the pieces of the puzzle in place for robust performance and threat management in these remote locations.

This can happen due to shortfalls in branch office IT management, which can include:

• No full-time IT staff on site
• Reduced visibility into network and service performance compared to headquarters or data center locations
• Limited or no visibility into traffic that doesn’t come back to the data center
• Difficulty in understanding the remote end-user experience and quantifying the impact of service degradations

Negating these shortfalls requires a more comprehensive approach to remote management encompassing the following areas:

The grep command makes it easy to find strings in text files on Linux systems, but that's just a start. It can be used to search through these files for multiple strings or regular expressions at the same time. It can also ignore case when needed, and it can count the lines in the resulting output for you. This post shows how to use grep in all these ways.

Basic grep

The simplest grep command looks like the one shown below. This "find string in file" command will show all the lines in the file that contain the string, even when that string is only part of a longer one.

$ grep word story The wording suggests there was more to the story than anyone wanted to admit. The sword had been left behind the shed. It was several days before it was 

Finding multiple strings

There are a number of ways to search for a group of strings in a single command. In the command below, the '|' character serves as an "or" function. The command will display any lines in the file that contain the word "xray", the word "tape" or both.

A group of about a dozen vendors announced this week that a test program for 5G network slicing had achieved 70% gains in the time required to programmatically create a network slice, marking a major step forward in the development of private 5G for enterprise users.

A network “slice,” as it’s called, is essentially a logically distinct subnetwork in a 5G deployment that can be used for a variety of purposes to maximize bandwidth use and provide on-demand 5G services to users. The basic idea is that automation in the 5G core can apply a layer of virtualization to wireless networks, letting a service provider “slice” off parts of its available spectrum and provide them to a customer as a discrete network.
