Predictive network technology promises to find and fix problems faster.

With the assistance of artificial intelligence (AI) and machine learning (ML), predictive network technology alerts administrators to possible network issues as early as possible and offers potential solutions.The AI and ML algorithms used in predictive network technology have become critical, says Bob Hersch, a principal with Deloitte Consulting and US lead for platforms and infrastructure. "Predictive network technology leverages artificial neural networks and utilizes models to analyze data, learn patterns, and make predictions," he says. "AI and ML significantly enhance observability, application visibility, and the ability to respond to network and other issues."To read this article in full, please click here

Backup: Don’t forget cell phones used for work

Some organizations’ important data may be going unprotected if an application on someone’s mobile device creates it and then it sits there without being backed up. If the device is lost or stolen, the data is gone.You might think it’s easy to solve this problem by installing a backup app on the phone and using it. Unfortunately, it’s not that simple.The security models of Android and iOS devices allow each application to see only the data created by that application; therefore, you cannot install a backup application and have it back up data of other applications. The only way around this is to root the phone, but that’s a problem if the employee is using their personal phone for work. Most people are uncomfortable rooting their phone, especially just to satisfy their boss’s backup needs.To read this article in full, please click here

Power to the engineering people

SPONSORED: The value of great engineering is often overlooked, yet almost every object we use on a daily basis has been meticulously designed and tested by somebody somewhere to deliver the best possible performance and meet exacting cost and efficiency requirements. …

DHCP Relaying in VXLAN Segments

After I got the testing infrastructure in place (simple DHCP relay, VRF-aware DHCP relay), I was ready for the real fun: DHCP relaying in VXLAN (and later EVPN) segments.

TL&DR: It works exactly as expected. Even though I had anycast gateway configured on the VLAN, the Arista vEOS switches used their unicast IP addresses in the DHCP relaying process. The DHCP server had absolutely no problem dealing with multiple copies of the same DHCP broadcast relayed by different switches attached to the same VLAN. One could only wish things were always as easy in the networking land.

Worth Reading: Off-Path Firewall with Traffic Engineering

I have blog post ideas sitting in my to-write queue for over a decade. One of them is why would you need a VRF (and associated router) between virtual servers and a firewall?

Andrea Dainese answered at least part of that question in his Off-Path firewall with Traffic Engineering blog post. Enjoy!

Streamlining Security with Multi-Cloud Networking

Enterprises need multi-cloud networking and security for all layers of the stack: infrastructure, apps and app delivery, and data.

This Week in Computing: Malware Gone Wild

Malware is sneaky AF. It tries to hide itself and cover up its actions. It detects when it is being studied in a virtual sandbox, and so it sits still to evade detection. But when it senses a less secure environment — such as an unpatched Windows 7 box — it goes wild, as if Tudor Dumitras, in a recently posted talk from red pills, which helps malware detect when it is in a controlled environment, and change its behavior accordingly. As a result, many of the signatures used for commercial malware detection packages may not Continue reading

Worth Reading: The Dangers of Knowing Everything

Another interesting take on ChatGPT in networking, this time by Tom Hollingsworth in The Dangers of Knowing Everything:

In a way, ChatGPT is like a salesperson. No matter what you ask it the answer is always yes, even if it has to make something up to answer the question.

To paraphrase an old joke: It’s not that ChatGPT is lying. It’s just that what it knows isn’t necessarily true. See also: the difference between bullshit and lies.

Briefings In Brief 103: Arista Enters The SD-WAN Arena

Arista Networks has announced two hardware WAN routers, the 5510 and the 5310, which are targeted at branch, edge, and remote sites. The routers run EOS with a full routing stack. The new hardware can run as standard routers, or be used for SD-WAN with all the features you’d expect, including support for multiple links and app identification. Ethan Banks and Drew Conry-Murray share what they learned in a briefing with the company and debate the strategy behind Arista's entry into the SD-WAN market.

Zero-trust Networks: Implementation is No Walk in the Park

Zero-trust network implementations can require an entire redefinition of your network architecture, the introduction of new technologies, and the training of both users and IT. Here’s what you need to know when you make your move to zero-trust.

Heavy Networking 671: Is ChatGPT Coming For Your Job?

On today's Heavy Networking we sub in a podcast from our Heavy Strategy channel. Greg Ferro from the Packet Pushers and Johna Till Johnson, CEO of Nemertes Research, discuss the impacts of ChatGPT and AI on the technology workspace, including whether human workers can partner with these tools to increase productivity and improve technology experiences. They don't have answers, but they do have unanswered questions.

Hedge 171: Paul Grubb on Zero Knowledge Middleboxes

Middleboxes are used in modern networking to sniff out attack traffic (IDS), block unwanted traffic (stateful packet filters), and share load among several different servers. Encryption, however, is making it hard for the middleboxes to do their job. Paul Grubb joins Tom Ammon and Russ White to discuss zero knowledge middle boxes, which allow operators to enforce arbitrary policies on the underlying traffic of an encrypted connection without decrypting it.

Use the language of your choice with Pages Functions via WebAssembly

On the Cloudflare Developer Platform, we understand that building any application is a unique experience for every developer. We know that in the developer ecosystem there are a plethora of tools to choose from and as a developer you have preferences and needs. We don’t believe there are “right” or “wrong” tools to use in development and want to ensure a good developer experience no matter your choices. We believe in meeting you where you are.

When Pages Functions moved to Generally Available in November of last year, we knew it was the key that unlocks a variety of use cases – namely full-stack applications! However, we still felt we could do more to provide the flexibility for you to build what you want and how you want.

That’s why today we’re opening the doors to developers who want to build their server side applications with something other than JavaScript. We’re excited to announce WebAssembly support for Pages Functions projects!

WebAssembly (or Wasm) is a low-level assembly-like language that can run with near-native performance. It provides programming languages such as C/C++, C# or Rust with a compilation target, enabling them to run alongside JavaScript. Primarily designed to run on Continue reading
