3. IP network architecture more complex.

INTRODUCTION
IP network architecture more complex.
MPLS or Multi Protocol Label Switching.
Uses Label appended to IP packets.
Routing switches just look or swap label and forward it.
Avoid routing table lookup.
Ravi Anand ( )

4. MOTIVATION TOWARD MPLS
B.TECH SEMINAR PRESENTATION-2017
MOTIVATION TOWARD MPLS
Earlier networking Protocol treat packet differently and receive differently.
Packets had different structures, with different lengths and fields.
Router and switches translate packets from one network to another.
Ravi Anand ( )

5. In MPLS networks, packets are assigned labels.
B.TECH SEMINAR PRESENTATION-2017
DEVELOPMENT OF MPLS
The Internet Engineering Task Force (IETF) MPLS working group was formed in 1997.
MPLS need not to inspect every field of every packet, and eliminating the need to re-format or encapsulate frames and cells.
In MPLS networks, packets are assigned labels.
Ravi Anand ( )

6. The architecture is split into two separate components:

9. OPERATIONS Packet travels from 10.0.0.0/24 to 10.2.0.0/24
B.TECH SEMINAR PRESENTATION-2017
OPERATIONS
Packet travels from /24 to /24
Ingress router R2 assign label 30
R3 swaps label 30 with Label 36
R4 removes the Label and deliver to customer edge router R5.

MPLS APPLICATION
MPLS Virtual Private Network
MPLS label loading is the key operation to implement VPN
Traffic Engineering
Process of selecting LSP chosen by data traffic in order to balance the links.

CONCLUSION
MPLS provides an effective design of technologies and protocols to solve the most pressing network-design problems.
MPLS are faster and secure as compared to IP routing.
The top label is used to get the traffic through the core, and the inner label is used to push the traffic into the destination VPN.
