The document discusses the need for unified MPLS networks to efficiently support increasing packet transport demands. It notes that service and revenue models are shifting from circuit-based to packet-based as traffic demands explode. It also discusses how events like cloud computing and LTE deployment are driving adoption of intelligent packet-based networks. Unified MPLS allows for a single end-to-end network that simplifies operations through protocol reduction and separation of transport from service operations. Leading network operators are adopting this approach to build more cost-effective networks that can improve return on investment.

2. • Service and revenue mixes are changing as packet transport requirements
explode
• The compelling events of Cloud and LTE are driving adoption of intelligent
packet based networks to deliver optimal transport
• Simplification by protocol reduction, minimal configuration and separation of
service from transport operations are all required to realize a cost effective
network that can be operated at large scale
• Advances in MPLS Technology make a single end to end control, data and
management plane feasible for today’s NGNs.
• The benefits are simplified operations, reduced skill set for
operations, elimination of both protocol translation between domains and
scale limitations of legacy technologies.
• Leading operators are adopting this approach now to develop a single
multiservice network that can improve ROI by the process of “build
once, use many times”.

5. • Packet transport delivers the most efficient and cost effective
solution for the exploding packet traffic demands seen in
networks today
• Infrastructure is converging to get better utilization of fiber and
microwave assets, driving the need for virtualization
• Compelling events of LTE for mobile and cloud for wireline drives
the need for intelligent packet networks
• Legacy TDM and ATM transport will persist for many years
• For converged packet transport, virtualization and legacy
support, the industry has chosen MPLS
• Unified MPLS now brings scale enhancements and operational
simplification to meet the most demanding operator needs

Full transformation to NGN needs
to occur from core to customer
Long term vision is critical, this will be
the network for the next decade
What is the most effective
technology choice that will:
Minimize CapEx and OpEx?
Provide carrier class service
delivery?
Maximize service agility?
Carriers want the deterministic attributes of transport
networks with the flexibility of the internet
