Juniper Networks PTX1000
Distributed applications within the Converged Supercore architecture

Overview:

The PTX1000 Packet Transport Router provides high-density 10GbE, 40GbE, and 100GbE interfaces for distributed core networks and network applications, meeting the demands of Internet service providers and high-volume content providers.

Occupying only two rack units, the PTX1000 is the industry's first fixed-configuration core router that enables service providers to organically distribute peering points throughout the network. It uses a rich IP/MPLS feature set without sacrificing performance or deployability, two factors on which total cost of ownership (TCO) pivots for service providers.

With 2.88 Tbps of forwarding capacity, the PTX1000 supports flexible interface configuration options ranging from 288 10GbE interfaces using a quad small form-factor pluggable plus (QSFP+) breakout module, 72 GbE interfaces at 40 Gbps using a QSFP+ breakout module, and 24 100GbE interfaces using QSFP28.

Like other routers in the PTX Series, the PTX1000 is powered by Juniper Networks ExpressPlus™ custom silicon to deliver predictable IP/MPLS packet performance and functionality.

Increased interactions between people and machines are creating huge volumes of traffic with increasingly unpredictable patterns. These dynamics have intensified the challenge of accommodating growth with traditional network products and architectures. A new approach, based on both physical and virtual innovation, will help service providers stay ahead of growing traffic demands while remaining profitable. PTX Series Packet Transport Routers with custom ExpressPlus silicon, built from the ground up with SDN in mind, deliver an architecture that reduces TCO with highly flexible, high-performance innovations that are easy to deploy.

Product Description

Juniper Networks® PTX Series Packet Transport Routers transform the core network with physical and virtual innovations that deliver unprecedented scale at a low cost. Two fixedconfiguration platforms are available: the PTX1000 Packet Transport Router, the industry's first 2 U packet transport routing device; and the PTX10002 Packet Transport Router, a second-generation device that doubles the density of the PTX1000 with Juniper Networks ExpressPlus™ silicon. 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. 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.
• Facility limitations: Service providers cannot grow their facilities exponentially forever. They need innovations that provide a low-touch deployment model optimized around space availability, facility power requirements, and floor weight thresholds. Transport-oriented central office locations have the added burden of meeting European Telecommunications Standards Institute (ETSI) standard depth. Any transit router innovation must operate within these constraints.

In order to address these challenges, cloud and communication providers need an innovative core router that satisfies three defining principles: performance, deployability, and SDN programmability. PTX1000 and PTX10002 fixed-configuration packet transport routers provide the foundation for a scaleout core backbone architecture, ensuring a consistent user experience across geographies. Both the PTX1000 and PTX10002 meet all existing traditional core requirements, easily fitting into cloud and communication provider networks that require transit focused IP/MPLS applications such as: Internet peering, scale-out metro and backbone topologies, and labelswitching router (LSR) optimized deployments.
