MPLS Label Switching

MPLS (Multiprotocol Label Switching) is a method used by internet networks to efficiently direct data. Instead of inspecting each packet's detailed information, MPLS attaches a short label to each data packet. This label guides the network on the quickest path to the destination. Switches and routers read these labels, not the full data, enabling faster and more reliable routing. Think of it like putting a zip code label on a letter—once labeled, it moves swiftly along predetermined routes without checking every detail along the way. MPLS improves network performance and supports various services like video, voice, and data.
