PacketbrewVRF Explained - How One Router Can Act Like Many
VRF Explained: How One Router Can Act Like Many In our last post, we covered Software Defined Networking. But how do you get the most out of your hardware when it has to serve multiple tenants who each need isolation? That’s where VRF comes in. It lets a single device behave as if it were multiple routers. In this post, we’ll cover what a VRF does and how you can use it.
Software Defined Networking - What It is and Why It Matters
Software Defined Networking (SDN): What It Is and Why It Matters Previously, we covered the different types of networks. But there’s another network architecture that’s become foundational to how modern infrastructure runs — and it’s called Software Defined Networking, or SDN.
As the name suggests, SDN is a network that’s defined by software. In this post, we’ll break down what it does, how it works, and how it can help you — whether you’re managing a small lab or a hyperscale data center.
Types of Networks Explained - From PAN to WAN And Everything In Between
Types of Networks Explained: From PAN to WAN (And Everything In Between) Networks provide connectivity for devices to exchange data. Think of a network as a highway for your data — moving information between devices at home, at the office, or in a classroom. But not all highways are the same size, and not all networks serve the same purpose.
Network Architectures That You Need to Know
Network Architectures That You Need to Know Your home Wi-Fi, your company’s office network, and the data centers behind services like Netflix all run on the same handful of proven architectural patterns. Get the architecture wrong, and you end up with bottlenecks and outages. Get it right, and the network just works.
Routing Table and Best Path Selection
Routing Table and Best Path Selection If you’ve ever looked at a routing table and wondered why one route was chosen over another, you’re not alone. Routers often have multiple ways to reach the same destination — but they never just “pick one.” There’s a strict, predictable process behind every decision.
