Introduction
Basic Concepts
Terminology
Applications
Configuration
Why MPLS?
Problems with IP routing and Forwarding
Ip routing
Growth and evolution of the Internet
The need to evolve routing algorithm
The need for advanced forwarding algorithm
routing vs. forwarding (switching)
 routing: flexibility
 forwarding: price/performance
 Can we forward/switch IP packets?
Allow speed of L2 switching at L3
Router makes L3 forwarding decision based on a single field:
similar to L2 forwarding  Sppppppeeeeed
What is MPLS ?
Defined by IETF in 1998
It stands for Multi Protocol label Switching.
Multiprotocol-as it can apply to multiple protocols
Layer 2.5 networking protocol.
MPLS Working
In Simple Words…
Packets enter MPLS Network at a “Label Edge Router”
(LER)
LER Affix a label to packet and forwards it to the MPLS
network
Label switches in the network at each hop makes
forwarding decision solely based on label. That decision
is made based on a pre-established “Label Switch Path”
(LSP).
Labels can be integrated with existing L2 info such as
DLCI or ATM VCs.
MPLS VPN applications
Point to Point
MPLS VPN Application (contd..)
Private LAN Service
MultiProtocol …
Many Technologies below…
MPLS Layer-2.5
Routing and Switching
(A Comparison..)
Router : no. of IP Packets assemble while Router
Checks into Routing Table…Hence Slow
Switch :A table is maintained containing enteries of
Input Port ,Output Port,label Applied to the outgoing
packet…Hence Fast
MPLS = Best of Routing + Best of Switching
LSR-Label
Switch Router
Router
SWITCH
Terminology LSR-Label Switch Router also
known as Provider Router or
P Router
LER – Label Edge Router also
known as Provider Edge Router
or PE Router.
FEC-Forward Equivalence
Class –Set of Packets with
identical characteristics which
may be forwarded the same
way.
Terminology contd..
Control Plane-
responsible for collecting
and propagating the
information that will be
used later to forward
incoming packets.

Comparison MPLS vs VPN
MPLS VPN
Flexibility-Less
Management-only ISP
Services-MPLS have Class of
Service
Security-No built in feature
Price- It is much expensive
(Source-RCR Wireless News)
Flexibility-More
Management-Customer
may be involved.
Services- VPN don’t
necessarily have Class of
Service i.e Traffic
Prioritization
Security- Broad Range –
authentication Strategies to
Complex Encryption
Price-Less
Protocols
LDP- Label Distribution Protocol
Creates, maintains, and distributes the MPLS labels. It
takes networks learned via the Routing Protocol and
binds prefix information to labels.
Protocols contd..
RSVP-TE-Resource Reservation Protocol - Traffic
Engineering is an extension of resource reservation
Protocol (RSVP) for traffic engineering.
 It supports the reservation of resources across an IP
Network. Applications running on IP end systems can
use RSVP to indicate to other nodes the nature
(bandwidth,jitter maximum burst, and so forth) of
the packet streams they want to receive
Application
Traffic Engineering
Allows a network administrator to make the path
deterministic and bypass the normal routed hop-
by-hop paths.
