Multiprotocol Label Switching (MPLS)

• MPLS is an advanced routing technique that operates below the IP layer, providing a means to direct packets from one node to another based on short labels rather than long network addresses.
• Efficiency: By using the MPLS label, routers can quickly forward packets without having to perform a detailed lookup for each packet, significantly speeding up the routing process.
• Label Field: The 20-bit Label field is used to identify a specific flow of packets, enabling efficient traffic management and faster data transfer across complex networks.
• Traffic Engineering: MPLS allows for better bandwidth utilization and management by directing data traffic along predetermined paths, reducing congestion and improving overall network performance.
