LSP (Label Switched Path)

A Label Switched Path (LSP) is a predetermined route that data packets follow across a network, managed by a technique called MPLS (Multiprotocol Label Switching). Instead of using complex addresses at each step, the network attaches a simple label to each packet, guiding it along an efficient, committed path. This means data is quickly and reliably moved from sender to receiver, often through multiple networks or points, ensuring quality of service. Think of it as a reserved express lane on a highway system, designed to streamline and prioritize the delivery of your data.
