Withcreating a deluge of traffic,the PTX1000, service providers now have the freedom to create new virtualized serviceswith increasingly unpredictableanywhere in the network and elastically create a Converged Supercore architecture withpatterns. These dynamicshave intensified the challengeto accommodate growth withtraditional network productsand architectures. However, anew approach, based on bothphysical and virtual innovations,is required to help serviceprecise traffic control without compromising the service experience.The Evolving LandscapeNew traffic dynamics like mobility, video, and cloud-based services are transformingtraditional network patterns and topologies. Stratified, statically designed and manuallyoperated networks must evolve to meet constantly growing volumes of traffic quickly andeconomically. Many operators have seen profitability stagnate and TCO grow under theproviders stay ahead of growingburden that growing traffic volumes are imposing.

PTX Series Packetremove rigid network layers.Transport Routers with customExpressPlus silicon, built fromthe ground up with SDN in mind,provide service providers with a Static scale: The service provider backbone handles the entire weight of the network’straffic. Therefore, it is paramount that the core network can grow organically, along withthe traffic, to meet escalating demands. Silicon, system, and SDN innovations for theConverged Supercore architecturecore empower service providers to scale faster than the traffic demands in an elegant,that reduces TCO with highlyelastic, redundant package—without requiring forklift upgrades.flexible, high-performanceinnovations for easy deployment. Static architecture: Virtualized services and the explosion of cloud-based applicationsare creating increasingly unpredictable traffic patterns. To handle this unpredictability,service providers need a flexible and dynamic architecture across all layers. Rigidarchitectures hinder rather than enable programmable, predictable, and trafficoptimized networks supporting any service, anywhere. Power challenges: For service providers, the operational cost to transmit a packetthrough 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 exceedsthe total cost of deploying the network infrastructure. Efficient core router powerutilization requires a holistic ground-up engineering approach. Facility challenges: Service providers cannot continue growing their facilitiesexponentially. They need innovations that provide a low-touch deployment modeloptimized around space availability, facility power requirements, and floor weightthresholds. Transport-oriented central office locations have the added requirement ofEuropean Telecommunications Standardization Institute (ETSI) standard depth, andany transit router innovation must be able to operate within these constraints.1

In order for PTX Series routers to lowerports via QSFP , and 24 x 100GbE ports via QSFP28. Like theoperational expenses, physical innovations at the core siliconare needed. PTX Series routers are powered by Juniper NetworksExpressPlus silicon, building upon the Juniper Networks Junos factor pluggable plus transceiver (QSFP ) breakout, 72 x 40GbE Express silicon concepts of low consistent latency and wirerate packet performance for both IP traffic and MPLS transportwithout sacrificing the optimized system power profile. All ofthese concepts are incorporated into the design along withfull IP functionality, preserving the spirit of the original JunosExpress chipset. The ExpressPlus silicon is the first purpose-builttelecommunication silicon to engineer a 3D memory architectureinto the base design for more than 1.6 billion filter operationsper second, dynamic table memory allocation for mammoth IProuting scale, and enormous power efficiency gains.rest of the PTX Series, the PTX1000 is powered by ExpressPlussilicon, offering predictable IP/MPLS packet performance andfunctionality. ExpressPlus silicon also eliminates the complexsawtooth packet profile found in elaborate over-engineerednetwork processing units (NPUs) deployed in other corerouters. This delivers the distributed peering scale (2 millionplus forwarding information base [FIB] and 5 million routinginformation base [RIB], also known as forwarding and routingtables, respectively), required to match expanding traffic demands.Features and BenefitsPerformance is one of the guiding design principles for the PTXSeries routers.
