Due to the labeling technology, the speed of performing lookups for destinations and routing is much faster than the standard IP table lookups non-MPLS routers have to perform.
Quality of Service
You can expect a higher standard of service such as reliability, speed, and quality. MPLS networks are able to assign priorities to the different packets based on what the labels say about that packet. Packets with greater priority, are given more bandwidth allocation. A packet that which is not deemed as high priority is given less.
Due to its inherent resilient & redundant Core setup, MPLS networks have the ablility to restore interrupted connections at a faster speed than typical networks.
MPLS offers greater security and are often required for companies which need enhanced privacy and security for their network needs.
MPLS network allows pro-active monitoring and manageability, ensuring the extreme reliability and security.
