growing demand for cloud-based services. For this reason, it has become paramount
Solution
Juniper Networks Converged
Supercore architecture simplifies
the overall network with three
simple principles: industryleading packet performance;
network de-layering through
optical integration; and leveraging
of SDN traffic optimization tools.
Benefits
• Cost-effective—Juniper’s
Converged Supercore
architecture lowers OpEx by
leveraging transit-optimized
routers to deliver industry-best
performance, low-power profile
per gigabit transported, space
optimization for any type of
central office application, and
network-wide SDN concurrent
traffic optimization.
• Revenue-enhancing—An
open, standards-based,
programmable SDN-controlled
infrastructure, the architecture

optimizing existing traffic to
increase revenue capacity.
to rethink the approach to multilayer networking—specifically, how to bring routing and
optical together to satisfy projected traffic demand and improve the overall TCO of the
network in the future.
Juniper’s Converged Supercore® architecture redefines the way networks are built,
collapsing multiple layers into a flat elastic fabric, including performance-optimized IP/
MPLS routing and metro/long-haul dense wavelength-division multiplexing (DWDM)
layers. The Converged Supercore architecture builds upon the virtual integration of IP/MPLS
technology and integrated coherent interfaces for extended terrestrial optical interconnect
with a centralized, near-real-time traffic optimization SDN controller. The extensible
Juniper Networks® NorthStar Controller programmability enables operators to dynamically
improve traffic utilization by enabling a network that runs hotter and that carries more
revenue-generating services.
The Challenge
The onslaught of new traffic dynamics like mobility, video, and cloud-based services is
transforming traditional network patterns and topologies. Stratified, statically designed,
and manually operated networks must evolve to meet demands quickly and more
economically. Many operators have seen profitability stagnate and TCO increase under the
weight that growing traffic demands have placed upon them.
Network operators for traditional models overprovision infrastructure months in advance
in anticipation of increasingly unpredictable traffic patterns and volumes. This causes
providers to outlay huge capital expenses in idle anticipation of the future. This imbalance
in the fundamental financial equation can no longer be sustained—operators need to
become more agile in order to optimize their existing network resources, shorten planning
cycles, and remove rigid network layers. Once this is done, service providers can begin
leveraging a highly intelligent Supercore infrastructure to increase revenues by creating new
customizable services.
High-Speed Universal Core Solution
Juniper’s high-speed universal core starts with the industry’s highest-performance core
router with the lowest operational cost for transit applications, built specifically for full IP,
express MPLS, transport integration and SDN control—Juniper Networks PTX Series Packet
Transport Router family. Building upon that platform, Juniper WANDL IP/MPLSView and
Juniper Networks NorthStar Controller extract even greater network traffic efficiencies with
programmable SDN intelligence.

Summary—Make Every Bit Generate
Revenue
Many operators realize that to enable new revenue-generating,
cloud-based services, the fundamentals of how networks get
built must change. Juniper Networks Converged Supercore
architecture facilitates this change by de-layering the network
into a virtual single fabric, predictably allowing operators to
optimize existing traffic patterns with offline design and planning
tools or with programmable online SDN control.
