Heavy Networking 614: eBPF, Cloud-Native Networking, And Other Modern Networking Trends
Today's Heavy Networking gets deep in the guts of what’s going on with all the modern trends in networking: cloud-native, containers, eBPF, Kubernetes, DPUs, and so on. Guests Brent Salisbury and Dave Tucker give their insider’s view of developments in cutting-edge networking tech. You’ll walk away with a better idea of what to pay attention to in the months and years to come.

Internet outage in Yemen amid airstrikes
The early hours of Friday, January 21, 2022, started in Yemen with a country-wide Internet outage. According to local and global news reports airstrikes are happening in the country and the outage is likely related, as there are reports that a telecommunications building in Al-Hudaydah where the FALCON undersea cable lands was hit.
Cloudflare Radar shows that Internet traffic dropped close to zero between 21:30 UTC (January 20, 2022) and by 22:00 UTC (01:00 in local time).
The outage affected the main state-owned ISP, Public Telecommunication Corporation (AS30873 in blue in the next chart), which represents almost all the Internet traffic in the country.
Looking at BGP (Border Gateway Protocol) updates from Yemen’s ASNs around the time of the outage, we see a clear spike at the same time the main ASN was affected ~21:55 UTC, January 20, 2022. These update messages are BGP signalling that Yemen’s main ASN was no longer routable, something similar to what we saw happening in The Gambia and Kazakhstan but for very different reasons.
So far, 2022 has started with a few significant Internet disruptions for different reasons:
1. An Internet outage in The Gambia because of a cable problem.
2. An Internet Continue reading
Technology Short Take 151
Welcome to Technology Short Take #151, the first Technology Short Take of 2022. I hope everyone had a great holiday season and that 2022 is off to a wonderful start! I have a few more links than normal this time around, although I didn’t find articles in a couple categories. Don’t worry—I’ll keep my eyes peeled and my RSS reader ready to pull in new articles in those categories for next time. And now for the content!
Networking
- Mike Fiedler explores differences in ways for container-to-container communication to occur.
- Aidan Steele examines how VPC sharing could potentially improve security and reduce cost.
- What do you think microsegmentation means?
- Nick Schmidt talks about using GitOps with the NSX Advanced Load Balancer.
Servers/Hardware
- The Next Platform takes a look at Amazon’s Graviton3 processor.
- Ru Singh provides a review of his M1-based MacBook Air.
- Here’s a great review of the Framework laptop.
- Losing to Apple—whose M-series chips are widely regarded as faster and more efficient than Intel’s chips—has apparently stung the chip giant into revving up the innovation engine. These details on their 12th-generation H processors shows that Intel appears to be intent to regain the lead. Time will tell how successful they Continue reading
Video: Machine Learning Techniques
After Javier Antich walked us through the AI/ML hype and described the basics of machine learning it was time for a more thorough look at:
- Machine learning techniques, including unsupervised learning (clustering and anomaly detection), supervised learning (regression, classification and generation) and reinforced learning
- Machine learning implementations, including neural networks, deep neural networks and convolutional neural networks.

Juniper Networks’ SD-WAN Can Now Be Operated Via Mist Cloud
Juniper Networks’ SD-WAN appliances and software can now be fully managed from Juniper’s Mist Cloud. It’s part of Juniper’s larger goal to Mist-ify its LAN and WAN portfolio. Juniper’s SD-WAN product is based on the Session Smart Routers (SSRs) from Juniper’s acquisition of 128 Technology. Customers can now use Mist Cloud to onboard SSR hardware, […]

Hedge 115: Mat Duggan and DevOps
Devops is the new normal—but, far too often, operations folks (like network engineers) are expected to become full-on developers, and developers are expected to understand operations in ways they never had to before. Mat Duggan joins Tom Ammon and Russ White to discuss why operations is not development IT
