Tech Bytes: Need Those Packets? Palo Alto Networks Introduces Traffic Replication In SASE (Sponsored)
Today on the Tech Bytes podcast we talk about traffic replication in SASE environments. Our sponsor is Palo Alto Networks, and they’ve added a new capability in Prisma Access that lets you replicate and then store traffic sent to the Prisma Access cloud service. That replicated traffic can then be used for deep packet analysis, forensics, or network analysis. We’ll talk about how Prisma Access replicates traffic, use cases, and more.

The complexity of the modern IT infrastructure seems ever-growing. Closed, proprietary networks are just not agile enough to keep pace. Meet SONiC.Measuring the Internet’s pulse: trending domains now on Cloudflare Radar
In 2022, we launched the Radar Domain Rankings, with top lists of the most popular domains based on how people use the Internet globally. The lists are calculated using a machine learning model that uses aggregated 1.1.1.1 resolver data that is anonymized in accordance with our privacy commitments. While the top 100 list is updated daily for each location, typically the first results of that list are stable over time, with the big names such as Google, Facebook, Apple, Microsoft and TikTok leading. Additionally, these global big names appear for the majority of locations.
Today, we are improving our Domain Rankings page and adding Trending Domains lists. The new data shows which domains are currently experiencing an increase in popularity. Hence, while with the top popular domains we aim to show domains of broad appeal and of interest to many Internet users, with the trending domains we want to show domains that are generating a surge in interest.
How we generate the Trending Domains
When we started looking at the best way to generate a list of trending domains, we needed to answer the following questions:
- What type of popularity changes do we want to capture?
- What Continue reading
API Standardization and Its Role in Next-gen Networking
For Network-as-a-Service and other next-gen networking technology to succeed, API standardization is essential.Worth Reading: MP-TCP in Hybrid Access Networks
Wouldn’t it be nice if your home router (CPE) could use DSL (or slow-speed fibre) and LTE connection at the same time? Even better: run a single TCP session over both links? The answer to both questions is YES, of course it could do that, if only your service provider would be interested in giving you that option.
We solved similar problems with multilink PPP in the networking antiquity, today you could use a CPE with an MP-TCP proxy combined with a Hybrid Access Gateway in the service provider network. For more details, read the excellent Increasing broadband reach with Hybrid Access Networks article by prof. Olivier Bonaventure and his team.

The unreasonable effectiveness of radio
Light and radio transmissions are the same thing, just using different frequencies.
How is it reasonable that I can transmit with a radio using the energy of a low energy light bulb (10 watts), and easily chat with someone 1800km away?
Even if you imagine a perfectly dark world, where the only light bulb is a 10W bulb in Sweden; How is it even possible that this could be seen in Italy? It’s not even a spotlight! It’s only vaguely aimed away from east-west, in favour of up, north, and south.
My little light bulb (radio) could be seen in (approximately) all of Europe. ~750 million people potentially could have received it at the same time. With 10 watts.
“Blink blink” — All of Europe can see my little lightbulb.
And this isn’t some specialized super duper antenna, nor was it set up by an expert, fine tuning everything. I just put up the antenna in a PVC pipe and connected it. We can’t even credit fancy computers digging signals out of the noise. This was not FT8, this was PSK31. I’m sure voice would also have worked.
I also used FT8 with these same 10W to check off Continue reading
Heavy Networking 691: Why OOB Infrastructure Is Critical For IT Ops & Automation With ZPE Systems (Sponsored)
On today’s Heavy Networking podcast, we look at how sponsor ZPE Systems is rethinking Out-Of-Band management for automated, NetOps-driven infrastructure. This includes tasks like device staging, deployments, upgrades, and more. And you don’t just have to take ZPE’s word for it; we also talk to a customer who’s using the products to run a retail business with a lean networking team that supports more than fifty sites.

In her Network Resilience Boot Camp keynote address, eSentire’s Tia Hopkins discuss why businesses today must re-examine their network resiliency strategies and implement new approaches.Don’t Let the Cybersecurity Trust Mark Become Like Food Labeling
I got several press releases this week talking about the newest program from the US Federal government for cybersecurity labeling. This program is something designed to help consumers understand how secure IoT devices are and the challenges that can be faced trying to keep your network secure from the large number of smart devices that are being implemented today. Consumer Reports has been pushing for something like this for a while and lauded the move with some caution. I’m going to take it a little further. We need to be very careful about this so it doesn’t become as worthless as the nutrition labels mandated by the government.
Absolute Units
Having labels is certainly better than not having them. Knowing how much sugar a sports drink has is way more helpful than when I was growing up and we had to guess. Knowing where to find that info on a package means I’m not having to go find it somewhere on the Internet1. However, all is not sunshine and roses. That’s because of the way that companies choose to fudge their numbers.
Food companies spent a lot of time trying to work the numbers on those nutrition labels for Continue reading
