What Is Network-as-a-Service?

Modern businesses rely on networks that connect users, clouds, data centers, and devices across multiple regions and environments. But building and maintaining these networks traditionally required physical hardware, manual configuration, and constant upkeep — often slowing down innovation and increasing costs. As organizations have shifted toward cloud computing, distributed workforces, and AI-driven applications, this old…
Nokia’s Event-Driven Automation: Simplifying AI Backend Networks

As AI continues to reshape how data centers operate, one of the biggest challenges has become keeping networks stable, responsive, and efficient — even as traffic grows more complex and workloads scale across thousands of GPUs. Nokia’s Event-Driven Automation (EDA) platform takes aim at that challenge, introducing a smarter, framework-driven way to manage the “nervous…
The Power of People Networking in IT: Why It Matters More Than You Think

Back while I was still working in logistics — stacking things on top of each other, and dodging forklifts — the idea of people networking had never really crossed my mind. To be fair, there aren’t nearly as many meetups or events in the distribution industry as there are in IT. (Although to give credit…
Building a Routing Table: How Routers Decide Where Your Data Goes

When you open your browser and type in a website address, your device needs to know where to send that request. That’s where routing tables come in. Think of them as digital road signs that guide packets of data across networks until they reach their destination. What Is a Routing Table? Every IP-enabled device —…
What Is IPsec and How Does It Protect Our Data?

When we send information across the internet—whether it’s an email, a video call, or sensitive business data—it travels through many networks and devices we don’t control. Without protection, that data could be intercepted, altered, or stolen. This is where IPsec (Internet Protocol Security) comes in. It’s a suite of protocols designed to secure communications over…
The Basics of Content Delivery Networks (CDNs): How They Work and Why They Matter

When you stream your favorite show, shop online, or scroll through social media, you probably aren’t thinking about where all that content is coming from. Behind the scenes, Content Delivery Networks (CDNs) play a huge role in making sure those videos load quickly, images display smoothly, and websites stay online—even when millions of people are…
Breaking Into IT: Building Your Foundation from the Ground Up

There is no definitive way to break into IT as it can be a different journey for each individual person, however I’ve put together this article based on my own experiences and experiences of those within my network. Getting started in IT can feel overwhelming. Certifications, degrees, labs, job listings asking for “3+ years of…
Network Communication: Unicast, Multicast, Anycast, and Broadcast

When devices communicate across a network, data doesn’t just float around aimlessly—it follows specific delivery methods depending on the type of communication. Whether you’re browsing the web, streaming a video, or sending routing updates, the underlying communication model determines how data travels. In this post, we’ll break down the four main types of network communication:…
Understanding Dynamic Routing and Routing Protocols

In networking, one of the most important responsibilities of a router is figuring out how to get data from point A to point B. While static routing works in smaller environments, it quickly becomes impractical as networks scale. That’s where dynamic routing comes in. What is Dynamic Routing? Dynamic routing allows routers to automatically exchange…
Understanding Routing Loops: Causes, Troubleshooting, and Handling STP Failures

In networking, one of the most frustrating and dangerous issues you can run into is a routing loop. When a routing loop occurs, packets circle endlessly between routers instead of reaching their destination, wasting bandwidth, consuming CPU cycles, and potentially bringing down parts of a network. Let’s dive into how routing loops occur, how to…
