National Institute of Science & Technology B.TECH TECHNICAL SEMINAR PRESENTATION-2017 MULTI PROTOCOL LABEL SWITCHING Seminar ID:2899 By RAVI ANAND : 201416041 Under the guidance of Deepika Rani Sahu Ravi Anand (201416041) [1] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 CONTENTS Introduction Motivation Toward MPLS Development Of MPLS Architecture MPLS Element MPLS Header Operation Key Features Conclusion Refrences Ravi Anand (201416041) [2] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 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 (201416041) [3] National Institute of Science & Technology 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 (201416041) [4] National Institute of Science & Technology 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 (201416041) [5] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 ARCHITECTURE • The architecture is split into two separate components: • forwarding component • control component Ravi Anand (201416041) [6] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 MPLS ELEMENTS • Forward Equivalence Class (FEC) • Ingress Label Edge Router (LER) • Egress Label Edge Router (LER) • Label Switch Router (LSR) • Label Switch Path (LSP) Ravi Anand (201416041) [7] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 MPLS HEADER • Label • CoS (Class of Service) • Stack Field (S) • Time to Live (TTL) Ravi Anand (201416041) [8] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 OPERATIONS • Packet travels from 10.0.0.0/24 to 10.2.0.0/24 • Ingress router R2 assign label 30 • R3 swaps label 30 with Label 36 • R4 removes the Label and deliver to customer edge router R5. Ravi Anand (201416041) [9] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 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. Ravi Anand (201416041) [10] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 Key Features • Scalability • Security • Implementation Cost Ravi Anand (201416041) [11] National Institute of Science & Technology B.TECH SEMINAR PRESENTATION-2017 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.
