Introduction
Multiprotocol Label Switching (MPLS) fuses the intelligence of routing with the performance of
switching and provides significant benefits to networks with a pure IP architecture as well as those with
IP and ATM or a mix of other Layer 2 technologies. MPLS technology is key to scalable virtual private
networks (VPNs) and end-to-end quality of service (QoS), enabling efficient utilization of existing
networks to meet future growth and rapid fault correction of link and node failure. Similar to Layer 2
networks (for example, Frame Relay or ATM), MPLS assigns labels to packets for transport across
packet- or cell-based networks. The forwarding mechanism throughout the network is label swapping,
in which units of data (for example, a packet or a cell) carry a short, fixed-length label that tells switching
nodes along the packet’s path how to process and forward the data.
