Answer:
MPLS (Multiprotocol Label Switching) is a protocol used in computer networking to improve the speed and efficiency of data packet transmission. It works by assigning a label to each packet that identifies the packet's destination, allowing routers to forward the packet along the most efficient path without having to analyze its contents. This reduces the processing time and overhead required for each packet, resulting in faster and more reliable data transmission.
MPLS is commonly used in large enterprise networks and service provider networks, where it is used to prioritize traffic and ensure that critical applications receive the necessary bandwidth and quality of service. It is also used to create virtual private networks (VPNs) that allow remote users to securely access corporate resources over the internet.
Overall, MPLS is a powerful and flexible networking technology that has become a critical component of modern data networks.
