Juniper (PTX10003-160C-DC) PTX10003 160C base system with 160 100GE ports or 32 400GE ports 4 3000W DC pow

Juniper Networks® PTX Series Packet Transport Routers transform the core network with physical and virtual innovations that deliver unprecedented scale at a low cost. Four fixed-configuration platforms are available: the PTX1000 Packet Transport Router, the industry's first 2 U packet transport routing device; the PTX10001 Packet Transport Router, the industry's first 1 U packet transport device optimized for cost-optimized transit routing, the PTX10002 Packet Transport Router, a secondgeneration device that doubles the density of the PTX1000 with Juniper Networks ExpressPlus™ silicon in addition to the PTX10003, the industry's first 3U 400-GbE enabled packet transport routing device. These packet transport routers give cloud and communication providers the freedom to develop and deliver new virtualized services anywhere in the network. They can also create an elastic architecture with precise traffic control without compromising the service experience.

The Evolving Landscape

New traffic dynamics such as mobility, video, and cloud-based services are transforming traditional network patterns and topologies. Stratified, statically designed, and manually operated networks must evolve to support the constantly growing volumes of traffic quickly and economically. Many operators have seen their profits stagnate and TCO grow under the burden that these growing traffic volumes are imposing. Service providers need to become more agile in order to optimize their existing network resources, shorten planning cycles, and remove rigid network layers.

Operators are facing the following challenges under the current environment:

• Static scale: The cloud and communication providers' backbone handles the full weight of network traffic. Therefore, it is paramount that the core network be able to grow organically along with traffic to meet escalating demands. 400-GbE, inline MACsec, Silicon, system, and SDN innovations for the core empower service providers to scale faster than the traffic in an elegant, elastic, redundant package-without requiring forklift upgrades.

• Static architecture: Virtualized services and the explosion of cloud-based applications are creating increasingly unpredictable traffic patterns. To handle this unpredictability, service providers need a dynamic, scale-out architecture across all layers to create programmable, traffic-optimized networks that support any service, anywhere.
  
  
• Power costs: For cloud and communication providers, the operational cost of transmitting a packet through the core is less than the cost of the power required to move that packet. In fact, projections suggest that over a few short years, the total power draw will exceed the cost of deploying the entire network infrastructure. Efficient power utilization by the core router requires a holistic ground-up engineering approach.
