NGN Challenges
Opportunities for network infrastructure savings
• Essential Application and service support
• New and legacy requirements
• Quality
• Ensure appropriate QoS and reliability
• Convergence with Virtualization
• Lower capex and opex by network optimization
MPLS addresses all three of these challenges!

MPLS Addresses Enterprise Challenges
In three critical NGN areas, MPLS helps:
Services:
Policy:
Connectivity:
Copyright © 2005 Juniper Networks, Inc.
Next-generation and legacy
interfaces, services, apps
supported without changes
Each stream, group, service or
application gets the required
QoS, availability, etc.
Collapse traffic onto a single
infrastructure, but maintain
separation, privacy, policy

Connectivity: Convergence with Virtualization
 More services on fewer networks saves money
• Convergence requires QoS, VPNs, traffic
engineering, L1 and 2 support, etc.
 Services never want to be converged
• Differences in QoS requirements, routing,
availability, privacy, regulatory needs
• Each service should experience its network
as custom-built for it
 How can we help customers converge, but not
seem to from a service point of view?

Many uses for MPLS in the Enterprise
•Simple ATM or Frame VPN replacement
•Outsourced IP VPN
•Internet access links
•Point-to-point TDM replacement circuits
•Hierarchical VPN carriage or peering
•Layered security element
•Hybrid carrier/enterprise network

Service Quality through Policy
Service Quality through Policy
 Essential applications require highly available
service, usually with good QoS
 Virtualization ensures separation of services,
yet each service needs its own treatment:
• Traditional QoS (delay, bandwidth, loss, etc)
• Availability (network resilience)
• Security (privacy, separation)
 MPLS supports both standards-based and unique
solutions in these three critical areas
 Without attention to service quality, no
converged network can meet business goals

Application and Service Support
 Native service environments preserve investments
 Enterprise networks are always in flux
• Old applications and services phasing out, new ones
phasing in
 Any convergence solutions must flexibly support this
condition of continual change
 Support must sometimes be generic (e.g. Internet,
IP) and sometimes specific (e.g. ATM CES, TDM)
 MPLS supports specific applications with standardsbased, partner, and proprietary solutions

MPLS Paths and VPNs
Acctg
 MPLS labels are
assigned to identify a
path, location, or both
 Locations and paths
together create VPNs
 Enterprises can use
VPNs to subdivide
networks in whatever
way works best for
them:
Ops
Sales
• By application
• By service
• By user group
• By security level

Hybrid Enterprise / Provider MPLS
 MPLS VPNs have been a
very successful service for
many providers
 Enterprises use these
services when they are more
cost-effective than building
their own VPNs
 Enterprises who build their
own MPLS VPNs can link
them with providers’, thus
creating a hybrid
 Remote workers and nonMPLS offices may access
the combined MPLS network
via encrypted tunnels

Carrier of Carrier MPLS
 Geographically distributed
enterprises often have
“islands” of network services
requiring interconnection
 Providers offer “carrier-ofcarrier” services to their
MPLS customers, both
carriers and enterprises
 MPLS interconnection exists
for services at layers 1, 2,
and 3 (e.g. pseudowires,
Ethernet, ATM, IP, etc.)
 MPLS networks may also be
linked by dark fiber, private
lines, or other “non-MPLS”
methods

Summary: Benefits of MPLS in the NGN
 All business applications are supported
• Legacy or NextGen, critical to best-effort
 Each application is assured the experience
(security, availability, performance) it requires
 Converged networks that “seem” separate
• One bill for one network infrastructure from
your provider, yet many services / apps
• One network to manage, control, secure,
maintain, and regulate

MPLS Technology 101
 MPLS uses small labels (placed after the L2
header) to switch traffic along a path
 These paths co-exist with and depend on IP, and
are set up and maintained by RSVP and LDP
 IP routing and forwarding proceeds as normal
using standard protocols and procedures
 Multiple tags can be used to tunnel paths inside
each other, or to identify endpoints
 That’s it! Routers use this infrastructure to
build MPLS-based services like VPNs
