Internet Architecture
Interconnection, peering, Data centers. How the Internet works. IXPs, transit, and other topics. Routing and Control Planes such as BGP and OSPF protocols. RPKI and IP resources are also covered.
Understanding Leaf and Spine Switching in Modern Data Centers
A leaf-and-spine design is a data center network topology that removes the traditional three-tier hierarchy and treats every path equally. Traditional three-tier networks build layers like access, distribution, and core. This structure creates choke points when traffic has to move northbound through specific devices. A leaf and spine fabric flattens that design so every leaf … Read more
Why Data Centers Are Suddenly Everywhere
All of these data centers are not showing up by accident. They are the physical response to a change in how the internet is used.
The three pillars of Data Center design
For network engineers, data center design goes beyond switches and routers. The goal is to create an environment where failures are predictable and repeatable, not just to ensure basic functionality.
Interconnection, Peering, and Internet Exchanges: A Technical Deep Dive
If you’ve ever wondered how the capital I Internet actually works, you’re not alone!

What is an AS-SET?
An AS-SET is a collection of Autonomous System Numbers grouped under a single name. Rather than listing each ASN individually in your routing policy, you just refer to the set, and the routing registry handles the details. You can think of it like a mailing list for networks.
Understanding the BGP Origin Code Attribute
When you check out a BGP route, you’ll notice several attributes that help routers decide which path to use. The Origin code is one of the simplest and is often overlooked
