Asking Meaningful Questions: What Problem Are We Trying To Solve?

At some point in your career, you’ll likely participate in a project that is a technical and implementation success but is still a failure. That’s because the wrong solution was implemented. For example, after weeks or months of hard work you might successfully deploy a client-based VPN solution, but because of application latency requirements a […]

SONiC builds muscle for enterprise-network service in 2023

The coming year could be a very big one for the open-source network operating system SONiC as it garners start-up support and increasing interest from major networking vendors.The Linux-based Software for Open Networking in the Cloud decouples network software from the underlying hardware and lets it run on hundreds of switches and ASICs from multiple vendors while supporting a full suite of network features such as Border Gateway Protocol (BGP), remote direct memory access (RDMA), QoS, and Ethernet/IP. It was developed and then open-sourced by Microsoft, which in April turned the project over to the Linux Foundation and its 450,000 developers. The vendor community supporting SONiC has been growing, too, and includes Dell, Arista, Nokia, Alibaba, Comcast, Cisco, Broadcom, Juniper Apstra, Edgecore, Innovium, Nvidia-Mellanox, Celetica and VMware.To read this article in full, please click here

Demo Bytes: vSphere UPT On The NVIDIA BlueField DPU

NVIDIA’s BlueField Data Processing Unit (DPU) can offload, accelerate, and isolate software applications such as networking, storage, and security from a server’s CPU. In this Demo Byte, we walk through using VMware’s vSphere UPT feature on a BlueField DPU to bring vMotion capabilities to the DPU. Our guest is Wes Kennedy, Senior Technical Marketing Engineer […]

ChatGPT and Creating For Yourself

I’m sure you’ve been inundated by posts about ChatGPT over the past couple of weeks. If you managed to avoid it the short version is that there is a new model from OpenAI that can write articles, create poetry, and basically answer your homework. Lots of people are testing it out for things as mundane as writing Amazon reviews or creating configurations for routers.

It’s not a universal hit though. Stack Overflow banned ChatGPT code answers because they’re almost always wrong. My own limited tests show that it can create a lot of words from a prompt that seem to sound correct but feel hollow. Many others have accused the algorithm of scraping content from others on the Internet and sampling it into answers to make it sound accurate but not the best answer to the question.

Are we ready for AI to do our writing for us? Is the era of the novelist or technical writer finished? Should we just hang up our keyboards and call it a day?

Hedge 157: Vendor Lock-in with Frank Seesink

Vendor lock-in has been an issue in networking for the entire time I’ve been working in the field—since the late 1980s. I well remember the arguments over POSIX compliance, SQL middleware standards, ADA, and packet formats. It was an issue in electronics, which is where I worked before falling into a career in computer networks, too. What does “vendor independence” really mean, and what are the ways network operators can come close to having it? Frank Seesink joins Russ White and Tom Ammon to rant about—and consider—solutions to this problem.

How to combat counterfeit network gear

In today challenging business and economic environment, everybody's looking for a deal. Yet there is one "bargain" that network managers should avoid at all costs – low-priced network devices that turn out to be counterfeit.No competent network manager would intentionally purchase a faux network component, but that doesn't mean it never happens. "If signs of counterfeit parts were obvious, this issue would probably be resolved quickly," says John Loucaides, senior vice president of strategy at security technology provider Eclypsium.Virtually every type of network device is shadowed by one or more unauthorized doppelgängers. Fake drop-in replacements are particularly prevalent. "This enables a wide variety of cheaper parts to be used in a non-obvious way, maximizing the benefit of providing a counterfeit device," Loucaides says. Sometimes, however, only a single component within a device is counterfeited. "Given a financial motive, this is likely the most expensive part being substituted for a cheaper part," he says.To read this article in full, please click here

Arista EOS Configuration Automation

I keep getting questions along the lines of “is network automation practical/a reality?” with arguments like:

Many do not see a value and are OK with just a configuration manager such as Arista CVP (CloudVision Portal) and Cisco DNA.

Configuration consistently is a huge win regardless of how you implement it (it’s perfectly fine if the tools your vendor providers work for you). It prevents opportunistic consistency, as Antti Ristimäki succinctly explained:

Alex Kim: Why I joined Cloudflare

I am excited to announce that as of November 1, I have joined Cloudflare as Country Manager of South Korea to help build a better Internet and to expand Cloudflare’s growing customer, partner, and local teams in Korea. We just opened a new entity (after making Seoul our 23rd data center, more than 10 years ago)  and I am the first official employee of Cloudflare Korea LLC in Seoul, which is truly a great moment and privilege for me.

A little about me

I was born in Korea and was educated in Korea until middle school, then I decided to move to Toronto, Canada to study film making to become a movie director. I finished high school and obtained a university degree in Toronto, during which I had the opportunity to be exposed to various cultures, as well as learn and become well-versed in the English language. I think it was a great time to learn how diverse people in the world are. My dream of becoming a movie director has changed over time for many reasons, but I think it is no coincidence that I Continue reading

Day Two Cloud 175: Deploying Kubernetes And Managing Clusters

On today's Day Two Cloud we continue our Kubernetes conversation with guest Michael Levan. Today's show focuses on Kubernetes deployments and managing clusters once they're up and running. We discuss whether Kubernetes is really more complex than traditional application infrastructure; examine management options such as GitOps, manifests, and Kubectl; share useful tools, and talk about why Kubernetes is all about APIs.
