BENEFITS

• Highly Scalable
• In VPN(Virtual Private Networks) MPLS support any-to-any communication among VPN sites
• for this no requirement of full mesh of PVCs or sub optimal routing.
• Explicit Routing capabilities. 
• It will be possible due to the MPLS Traffic Engineering.
• MPLS enables an ATM switch to perform virtually all of the functions of an IP router.
• Eliminates the dependence on particular OSI layer technology.
• Eliminate the need for multiple layer-2 networks to satisfy different types of traffic.
