Data Sheet PTX1000 Packet Transport Router Product Overview Product Description Increased interactions between The Juniper Networks PTX1000 Packet Transport Router transforms the core network people and machines are with physical and virtual innovations that deliver unprecedented scale at a low cost. With creating a deluge of traffic, the PTX1000, service providers now have the freedom to create new virtualized services with increasingly unpredictable anywhere in the network and elastically create a Converged Supercore architecture with patterns. These dynamics precise traffic control without compromising the service experience. have intensified the challenge to accommodate growth with The Evolving Landscape traditional network products New traffic dynamics like mobility, video, and cloud-based services are transforming and architectures. However, a traditional network patterns and topologies. Stratified, statically designed and manually new approach, based on both operated networks must evolve to meet constantly growing volumes of traffic quickly and physical and virtual innovations, economically. Many operators have seen profitability stagnate and TCO grow under the is required to help service providers stay ahead of growing burden that growing traffic volumes are imposing. Service providers need to become more traffic demands while remaining agile in order to optimize their existing network resources, shorten planning cycles, and profitable. PTX Series Packet remove rigid network layers. Transport Routers with custom • Static scale: The service provider backbone handles the entire weight of the network’s ExpressPlus silicon, built from traffic. Therefore, it is paramount that the core network can grow organically, along with the ground up with SDN in mind, the traffic, to meet escalating demands. Silicon, system, and SDN innovations for the provide service providers with a Converged Supercore architecture core empower service providers to scale faster than the traffic demands in an elegant, that reduces TCO with highly elastic, redundant package—without requiring forklift upgrades. flexible, high-performance • Static architecture: Virtualized services and the explosion of cloud-based applications innovations for easy deployment. are creating increasingly unpredictable traffic patterns. To handle this unpredictability, service providers need a flexible and dynamic architecture across all layers. Rigid architectures hinder rather than enable programmable, predictable, and traffic- optimized networks supporting any service, anywhere. • Power challenges: For service providers, the operational cost to transmit a packet through the core is far exceeded by the power requirements to move that packet. Service providers have determined that the total power draw over a few years exceeds the total cost of deploying the network infrastructure. Efficient core router power utilization requires a holistic ground-up engineering approach. • Facility challenges: Service providers cannot continue growing their facilities exponentially. 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 requirement of European Telecommunications Standardization Institute (ETSI) standard depth, and any transit router innovation must be able to operate within these constraints.

The PTX1000 expands the applications innovative core router that delivers three defining principles: scope that the Converged Supercore architecture addresses, performance, deployability, and SDN programmability. With enabling service providers to implement a distributed core Juniper Networks® PTX1000 Packet Transport Router, Juniper architecture for interconnecting growing cloud services. Service introduces the industry’s only fixed core router that exceeds providers can distribute peering points to match traffic demand these requirements and easily fits into the service provider with an optimized core router without sacrificing performance or network, expanding the Juniper Networks Converged Supercore® deployability. The PTX1000 is the industry’s only fix configuration architecture beyond lean label-switching router (LSR) core router in a compact, 2 U form factor, making it easily deployments. deployable in space-constrained Internet exchange locations, remote central offices, and embedded peering points anywhere PTX Series in the network, including cloud-hosted services. The Juniper Networks PTX Series Packet Transport Routers bring The PTX1000 operates at 2.88 Tbps in a fixed core router physical and virtual innovations to the service provider core configuration and supports flexible interface configuration network. These directly address concerns about operational options, including 288 x 10GbE ports via a quad small form- expenditures while scaling organically to keep pace with factor pluggable plus transceiver (QSFP+) breakout, 72 x 40GbE growing traffic demands. In order for PTX Series routers to lower ports via QSFP+, and 24 x 100GbE ports via QSFP28. Like the operational expenses, physical innovations at the core silicon rest of the PTX Series, the PTX1000 is powered by ExpressPlus are needed. PTX Series routers are powered by Juniper Networks silicon, offering predictable IP/MPLS packet performance and ExpressPlus™ silicon, building upon the Juniper Networks Junos® functionality. ExpressPlus silicon also eliminates the complex Express silicon concepts of low consistent latency and wire- sawtooth packet profile found in elaborate over-engineered rate packet performance for both IP traffic and MPLS transport network processing units (NPUs) deployed in other core without sacrificing the optimized system power profile.
