Our Price: $64,400.00
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.
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.
Figure 1: PTX Series Routers deliver performance, flexibility, and SDN programmability for service providers.
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.
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.
Architecture and Key Components:
New and emerging traffic dynamics like mobility, video, and cloud-based services are transforming traditional network patterns and topologies. Networks that are stratified, statically designed and manually operated must adapt to meet demands quickly and more economically. Many operators have seen profitability stagnate and TCO grow under the weight of growing traffic demands.
In anticipation of increasingly unpredictable traffic patterns and volumes, many service providers overprovision their infrastructure months in advance. This requires considerable capital outlay for equipment that largely sits idle. This financial imbalance is unsustainable. Instead, operators need to become more agile to optimize existing network resources, shorten planning cycles, and remove rigid network layers. Once this is done, service providers can leverage a highly intelligent Converged Supercore infrastructure to increase revenues by creating new customizable services.
Juniper Networks Converged Supercore architecture, shown in Figure 1, is composed of Converged Supercore LSR, Converged Supercore IP Backbone, Transport Integration, Juniper Networks Junos Space Network Management Platform, and NorthStar Controller for SDN Programmability.
- The Converged Supercore LSR enables service providers to leverage the heart of the core MPLS backbone with a scalable, cost-optimized network.
- The Converged Supercore IP Backbone expands the architecture to address additional applications such as Internet backbone, Internet peering, infrastructure edge, back-end data center interconnect and metro-regional cores, fully collapsing IP with optical transport. A wide breadth of applications are available to service providers with Converged Supercore architectures, helping them achieve industry-low TCO and scaling each application organically as demand dictates.
- Junos Space Network Management Platform provides comprehensive management across the Converged Supercore architecture with broad fault, configuration, accounting, performance, and security management (FCAPS) capabilities; same-day support for new Junos OS releases; a task-specific user interface; and northbound APIs for integrating with existing network management systems (NMS) or operations/business support systems (OSS/BSS).
- NorthStar Controller, the industry-first traffic optimization SDN controller which lets service providers automate and engineer traffic across their SDN, increases utilization while reducing redundancy. Combining the power of Junos OS, WANDL optimization algorithms, and transport abstraction, NorthStar Controller enables Converged Supercore design across all networking layers, runtime traffic optimization, and “what-if” analysis. The result—new levels of control and visibility that help you avoid costly overprovisioning.
PTX Series Hardware Components
The key hardware components of PTX Series Packet Transport Routers are the FPC, PIC, Routing Engine (RE), and Switch Interface Board (SIB).
FPC and PIC
The first-generation and second-generation FPC line cards for the PTX5000 are based on the Junos Express chipset, making the PTX5000 the industry’s leading core router for LSR applications. Introducing the third-generation FPC line card for the PTX5000, based on custom Juniper ExpressPlus Silicon, expands the PTX5000’s application scope, making it the leading core router for LSR, Internet backbone, peering, and transport integration. The modular FPC design for the PTX5000 provides investment protection by allowing interchangeable PICs between generations of FPCs and deploying different PIC types simultaneously in a single FPC.
The first generation small form-factor FPC line card for the PTX3000 is based upon the Junos Express chipset, making the PTX3000 the industry’s leading space-constrained core router for LSR applications. Introducing the third-generation FPC line card for the PTX3000, based on custom Juniper ExpressPlus Silicon, expands the PTX3000’s application scope, making it the industry’s leading space-constrained core router for LSR, internet backbone, peering, and optical transport integration. The PTX3000 FPC architecture matches a single FPC slot with a single PIC slot for a 1:1 mapping schema. The PTX3000 and PTX5000 also share PIC types for interchangeable sparing.
Routing Engine/Control Board Complex
The Control Board (CB), which runs Juniper Networks Junos operating system, works with the RE to provide control plane and chassis management functionality while maintaining RoHS compliance. Software processes running on the RE manage the routing tables, while the protocols running on the switch control all of the interfaces, manage chassis functions, and provide the interface for system management and user access. The system can house two RE/CB complexes, with one acting as the primary and the other acting as the standby ready to take over in case of failure. The RE communicates with the CB via a pair of 10GbE links and a Peripheral Component Interconnect (PCI) bus.
Both the PTX5000 and PTX3000 switch fabric are engineered with a 9-slot all-active SIB architecture. In the case of a SIB failure, the remaining eight active SIBs maintain enough switch fabric capacity to support full line packet performance per slot— 24Tbps of total system capacity for the PTX5000 and 8Tbps of total system capacity for the PTX3000.
The PTX Series routers deliver powerful Junos OS chassis management that allows environmental monitoring and fieldreplaceable unit (FRU) control. Chassis management delivers a faster primary switchover, enhanced power budgeting with a modular power management, reduced power consumption for partly populated systems, granular control over FRU power-on, multi-zone cooling with better fan speed control for reduced noise, and CPU leveling during monitoring intervals.
The PTX Series simplifies the management function based on the elegance and simplicity of the Junos operating system.
