What is MPLS networks?

Multiprotocol Label Switching (MPLS) is a data forwarding technique used to increase the speed and control the flow of network traffic. Instead of relying on complex IP address lookups at each hop, MPLS uses short path labels to forward packets between nodes, significantly improving performance. It is commonly used in VPNs, traffic engineering, and quality of service (QoS) implementations in service provider networks and large enterprise networks.
