MPLS Definition: MPLS (Multiprotocol Label Switching) is a protocol used in telecommunications networks to speed up and shape traffic flows along predetermined paths.
MPLS (Multi-protocol Label Switching) is a protocol used in telecommunications networks to efficiently direct data packets along predefined paths. It operates at layer 2.5 of the OSI model, combining the speed of layer 2 switching with the flexibility of layer 3 routing. MPLS assigns labels to packets, allowing routers to make forwarding decisions based on these labels rather than IP addresses. This enables faster and more reliable data transmission, improves network performance, and enhances overall security by segmenting traffic and providing traffic engineering capabilities.
