MPLS Applications

  • MPLS change network design 
    • by eliminating the need for an Overlay (full mesh of routers).
  • Performance is improved 
    • because packets are switched instead of routed.
  • QoS can be implemented end to end
    • by having an PE router classify packets & map a value to the Experimental (EXP) field of the MPLS label stack.
  • Traffic Engineering is made possible through label stacking & traffic-engineered tunnels.
