Segment Routing (SR) is a flexible and scalable way of performing source routing. The source chooses a path and encodes it in the packet header as an ordered list of segments. Each segment is ...

What is the network layer? Located at Layer 3 of the Open Systems Interconnection (OSI) communications model, the primary function of the network layer is to move data into and through other networks.

I love new security testing tools. There is nothing quite like finding some magical bits of code allowing you to use and abuse protocols in unique and unnatural ways. I was introduced to Loki at ...

A Layer 3 switch -- also referred to as a multilayer switch -- combines the duties of a switch and a router. It acts as a switch because it connects devices that are on the same IP subnet or virtual ...

Routing protocols have far-reaching effects on the performance and reliability of your network, but sorting out the differences between them can be a challenge. Choose the best one for your network by ...

For years, the average network has been dominated by the Layer 2 switch. Now as network complexity increases and applications demand greater functions from the network, Layer 3 switches are coming out ...

Organizations in healthcare, finance, and other sensitive industries want to use large AI models without exposing private data to the cloud servers running those models. A cryptographic technique ...

Routing got the early lead on switching thanks to Cisco, then the two technologies melded and evolved. It was the debate that separated Cisco from the pack and forever changed the enterprise network ...
