Introduction

Multiprotocol Label Switching (MPLS) fuses the intelligence of routing with the performance of
switching an d provides signific an t b enefits to n etworks with a p ure IP ar ch itec ture as w ell as th o se w ith
IP and ATM or a mix of other Layer 2 technologies. MPL S technology i s key to scalab le 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 exam ple , Fra me R ela y o r ATM), M PLS assign s la be ls to pa ckets fo r tr an sport acr oss

in which units of data (for example, a packet or a cell) carry a short, f ixed-length label that tells switching
nodes along the packet’s path how to process and forwar d the data.
