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

8 Copyright © 2005 Juniper Networks, Inc. www.juniper.net 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 Service Quality through Policy

10 Copyright © 2005 Juniper Networks, Inc. www.juniper.net 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 standards- based, partner, and proprietary solutions Application and Service Support

12 Copyright © 2005 Juniper Networks, Inc. www.juniper.net MPLS Paths and VPNs MPLS labels are assigned to identify a path, location, or both Locations and paths together create VPNs Acctg Sales Ops Acctg Ops Enterprises can use VPNs to subdivide networks in whatever way works best for them: By application By service By user group By security level
13 Copyright © 2005 Juniper Networks, Inc. www.juniper.net Hybrid Enterprise / Provider MPLS MPLS VPNs have been a very successful service for many providers Enterprises who build their own MPLS VPNs can link them with providers’, thus creating a hybrid Enterprises use these services when they are more cost-effective than building their own VPNs Remote workers and non- MPLS offices may access the combined MPLS network via encrypted tunnels ipsec pptp
14 Copyright © 2005 Juniper Networks, Inc. www.juniper.net Carrier of Carrier MPLS Geographically distributed enterprises often have “islands” of network services requiring interconnection MPLS interconnection exists for services at layers 1, 2, and 3 (e.g. pseudowires, Ethernet, ATM, IP, etc.) Providers offer “carrier-of- carrier” services to their MPLS customers, both carriers and enterprises MPLS networks may also be linked by dark fiber, private lines, or other “non-MPLS” methods
15 Copyright © 2005 Juniper Networks, Inc. www.juniper.net 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

17 Copyright © 2005 Juniper Networks, Inc. www.juniper.net 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
