Juniper Networks PTX3000
Converged Supercore router for space- and power- constrained environments

Overview:

Increased interactions between people and machines are creating a deluge of traffic, with increasingly unpredictable patterns. These dynamics have intensified the challenge to meet growth with traditional network products and architectures. A new approach, based on both physical and virtual innovations, is required to help service providers stay ahead of growing traffic demands while remaining profitable. Juniper Networks PTX Series Packet Transport Routers with custom ExpressPlus Silicon, built from the ground up with SDN in mind, provide service providers with a Converged Supercore architecture that reduces TCO with highly flexible, high-performance, and deployability innovations.

Product Description

New traffic dynamics like mobility, video, and cloud-based services are transforming traditional network patterns and topologies. Stratified, statically designed and manually operated networks must evolve to meet demands quickly and economically. Many operators have seen profitability stagnate and total cost of ownership (TCO) grow under the burden that growing traffic demands 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.

• Static scale: The service provider backbone handles the entire weight of the network's traffic. Therefore, it is paramount that the core network grows organically, along with the traffic. The silicon, system, and SDN innovations for the core empower service providers to scale faster than the traffic demands themselves in an elegant, elastic, redundant package-without requiring forklift upgrades.
• Static architecture: Virtualized services and the explosion of cloud-based applications are creating traffic patterns that are increasingly unpredictable. To handle this unpredictability, service providers need their architectures to be flexible and dynamic across all layers. A rigid architecture hinders rather than enables programmable, predictable, and traffic-optimized networks supporting any service, anywhere.
• Power challenges: For service providers, the operational cost to transmit a bit through the core is far exceeded by the power requirements to move that bit. 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 packet transport innovation must fit these constraints.

In order to address these challenges, service providers need an innovative core router that delivers three defining principles: performance, deployability, and SDN programmability. With Juniper Networks® PTX Series Packet Transport Routers, Juniper is introducing the industry's only core router that exceeds these requirements and easily fits into the service provider network, expanding the Juniper Networks Converged Supercore® architecture beyond lean LSR deployment, as shown in Figure 1.

PTX Series

The PTX Series Packet Transport Routers bring physical and virtual innovations to the service provider core network that directly address concerns about operational expenditures while scaling organically to keep pace with growing traffic demands. In order for PTX Series routers to lower operational expenses, physical innovations at the core silicon are needed. PTX Series routers are powered by Juniper Networks ExpressPlus™ Silicon, building upon the Juniper Networks Junos Express silicon concepts of low consistent latency and wire-rate packet performance for both IP traffic and MPLS transport without sacrificing the optimized system power profile. All of these concepts are incorporated into the design along with full IP functionality, preserving the spirit of the original Junos Express chipset. The ExpressPlus Silicon is the first purpose-built telecommunication silicon to engineer a 3D memory architecture into the base design for over 1.6 billion filter operations per second, dynamic table memory allocation for mammoth IP routing scale, and enormous power efficiency gains. The ability to address service provider core networking requirements of performance, deployability, and SDN control begins with the silicon. The integration of optical transport with 100GbE coherent technology further improves the economics of both metro and core networks. With PTX Series routers powered by the Juniper ExpressPlus Silicon, service providers can now deploy a Converged Supercore architecture with the efficiency of a lean core deployment with Juniper Networks NorthStar Controller SDN control, a robust full-featured Internet backbone router, and a converged regional IP/MPLS core router with integrated 100GbE coherent transport for superior performance, elegant deployment, and SDN programmability.

Performance is one of the guiding design principles for the PTX Series routers. This focus empowers service providers with superior scale to match increased traffic demands and simplified network engineering challenges with predictable system latency to improve the overall service experience and best in-class resiliency to ensure that service providers meet strict customer SLAs.

Deployability is the other guiding design principle for the PTX Series routers that focuses on power, space, and weight- fundamental concerns that impact the service providers' operational budget with respect to growing traffic demands.

SDN programmability brings virtual innovations to the service provider core, while the Juniper Networks NorthStar Controller is an open, standards-based solution that optimizes both the IP layer and the transport layer with precise SDN control, allowing service providers to automate and scale operations.

PTX5000

The Juniper Networks PTX5000 Packet Transport Router transforms the core network with physical and virtual innovations for unprecedented scale and cost. Service providers now have the freedom to create new virtualized services anywhere in the network and elastically create a Converged Supercore architecture with precise traffic control without sacrificing the service experience. The PTX5000, for the first time, lets service providers seamlessly scale IP/MPLS traffic without sacrificing performance and deployability, the contributors to eroding TCO analysis for service providers. The PTX5000 focus is on the Converged Supercore architecture for service providers, which is optimized for LSR, Internet backbone, peering, and dense 100 Gbps opticalcoherent DWDM applications for large, high-speed, massivescale networks. As such, for the first time, service providers can match traffic demand with optimized core router performance and deployability. The PTX5000, the only core router that can be deployed in a standard 19-inch telecommunications rack, stands 36U high with eight line-card slots, two redundant route engine slots, and nine switch fabric slots. At 3 Tbps per line-card slot, the PTX5000 supports 24 Tbps of total system capacity. Powered by the Juniper ExpressPlus Silicon, the PTX5000 offers predictable IP/MPLS packet performance and functionality, eliminating the complex sawtooth packet profile found in elaborate overengineered NPUs deployed in other core routers. The PTX5000 supports 240 x 100GbE interfaces (in QSFP28 optic form factors) in a single chassis, delivering the scale required to match expanding traffic demand.

The PTX5000 also supports the industry's densest 100GbEcoherent DWDM linecard with 1 Tbps capacity, blending bestof-class IP/MPLS performance with optical transport to flatten network layers.

In many countries, as well as smaller central offices and lower bandwidth applications, the Juniper Networks PTX3000 Packet Transport Router is the perfect Converged Supercore router. The PTX3000 brings unprecedented capacity in a 22U package that supports 8 Tbps per chassis or 16 Tbps per one standard 19-inch telecommunications rack, all at wire-rate performance. Powered by custom Juniper ExpressPlus Silicon, the PTX3000, like the PTX5000, delivers predictable IP/MPLS packet performance and functionality, eliminating the complex sawtooth packet profile found in elaborate over-engineered NPUs deployed in other core routers.

The PTX3000 is the only Converged Supercore platform that complies with 300 mm ETSI standards for both transport and space-constrained central office environments, making it the most globally deployable core router on the market. It supports up to 8 FPCs, each of which supports one PIC. The PTX3000 can support 80 x 100GbE interfaces in a single chassis, with support for gray and coherent optic technology. The PTX3000 enables service providers to build a Converged Supercore architecture that optimizes LSR, Internet backbone, peering, and optical convergence applications for smaller regional deployments. As such, for the first time, service providers can match traffic demand with optimized core router performance and flexible deployments. With its ultra-optimized form factor, the PTX3000 is ideally positioned for space-constrained colocation facilities such as optical transport environments, central office locations in emerging markets where space and power are at a premium, smaller service providers wanting Converged Supercore advantages, and next-generation metro regional networks.
