MPLS Benefits
MPLS de-couples IP packet forwarding from the information carried in the IP packet header
- Conventional IP routing forwards packets based upon the destination IP address in the IP header
Allows new routing functionality - new forwarding paradigms not available with conventional IP routing
MPLS today is the enabler for new functionality / services:
- VPNs
- Traffic Engineering
- Layer 2 transport
- Guaranteed bandwidth services
- Multi-Protocol Lambda Switching
