Changing market dynamics have intensified the challenge of accommodating growth with traditional products and architectures. Juniper’s secure and automated multicloud solution helps cloud-based networks quickly react to these evolving conditions, accelerating service delivery with world-class products and innovative architectural components. PTX Series Packet Transport Routers with custom ExpressPlus silicon are an integral part of this solution, delivering a massively scalable and efficient core architecture across space- and power-constrained service provider and enterprise networks, reducing TCO with innovative, highly flexible, highperformance platforms that are easy to deploy.
Juniper Networks® PTX Series Packet Transport Routers transform the core network with physical and virtual innovations that deliver unprecedented scale at a low cost. Three fixed-configuration platforms are available: the PTX1000 Packet Transport Router, the industry’s first 2 U packet transport routing device; the PTX10001 Packet Transport Router, the industry’s first 1 U packet transport device optimized for cost-optimized transit routing, the PTX10002 Packet Transport Router, a secondgeneration device that doubles the density of the PTX1000 with Juniper Networks ExpressPlus™ silicon in addition to the PTX10003, the industry’s first 3U 400-GbE enabled packet transport routing device. 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. 400-GbE, inline MACsec, 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, scalable core router that satisfies three defining principles: performance, deployability, and SDN programmability. The PTX1000, PTX10001-36MR, PTX10002, and PTX10003 fixed-configuration packet transport routers provide the foundation for a scale-out core backbone architecture, ensuring a consistent user experience across geographies. The PTX1000, PTX10001-36MR, PTX10002, and PTX10003 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 label-switching router (LSR) optimized deployments.
Architecture and Key Components:
The PTX1000, PTX10001-36MR, PTX10002, and PTX10003 fixed-configuration packet transport routers bring physical and virtual innovation to the cloud and service provider core networks, addressing concerns about operational expenditures while scaling organically to keep pace with growing traffic demands with the following features:
- Core routing: The PTX1000, PTX10001-36MR, PTX10002, and PTX10003 employ a massively scalable yet compact 1, 2, or 3 U form factor with secure connectivity and high flexibility.
- Peering: The PTX Series fixed platforms are perfect for scale-out peering in space- and power-constrained environments with full traffic visibility and L3 services.
- LSR: The PTX Series fixed platforms provide 2.88 Tbps to 16 Tbps aggregate capacity for multi-plane core networks as an LSR router. They can also be positioned as an LSR fabric node in spine-leaf architectures for increased scale and reduced blast radius.
- CDN Gateway: The compact PTX Series offers high routing scale in a 1, 2, or 3 U fixed form factor for full traffic statistics visibility and deep buffers.
- Data Center Interconnect (DCI): The PTX10001-36MR and PTX10003 offer secure inline MACsec with no compromise in throughput or latency, and an extended range enabled by 400GbE ZR / ZR+.
Innovations in Silicon
Physical innovations at the core silicon level enable the PTX Series fixed-configuration routers to reduce OpEx and accommodate scale-out architectures with smooth migration paths as traffic patterns change.
ExpressPlus and Express-Based Silicon
The PTX1000 and PTX10002 are powered by ExpressPlus silicon, delivering predictable IP/MPLS packet performance and functionality. The PTX10003 is powered by functionally equivalent ExpressPlus Silicon to support high-density 100/200/400GbE interfaces and inline MACsec with no performance penalty while delivering the same IP/MPLS functionality. ExpressPlus silicon eliminates the complex sawtooth packet profile found in elaborate, over-engineered network processing units (NPUs) deployed in other core routers. This delivers the peering scale required to match expanding traffic demands.
These devices build 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. These concepts are incorporated into the PTX Series design along with full IP functionality, preserving the spirit of the original Junos Express chipset. The ExpressPlus silicon is the first purpose-built telecommunications silicon to engineer a 3D memory architecture into the base design for more than 1.6 billion filter operations per second, dynamic table memory allocation for mammoth IP routing scale, and enormous power efficiency gains. The PTX10003 supports inline MACsec on all interfaces using 10/40/100GbE.
The PTX10001-36MR is powered by the highly scalable, next-generation ASIC in the Express silicon family, Juniper Triton silicon—the industry’s first inline MACsec for 400GbE chips that supports universal multirate QSFP56-DD. Juniper Triton silicon delivers consistently low latency, 8m counters, 256 AES MACsec encryption supported on all ports, and wire-rate packet performance for IP traffic without sacrificing the optimized system power profile. Preserving the spirit of the Junos Express silicon family, Juniper Triton silicon is the first purpose-built telecommunications silicon to incorporate a 3D memory architecture into the base design, offering the industry’s highest packet performance per gigabit in the fewest rack units. It also provides dynamic table memory allocation for massive IP routing scale while delivering tremendous power efficiency gains at 0.14 Watts/Gig.
The ability to address a provider’s core networking requirements—scale, operational flexibility, and SDN control—begins with the silicon. With the PTX Series fixed-configuration routers, operators can now deploy a core architecture with SDN control. Combining Juniper Networks NorthStar Controller with a robust full-featured Internet backbone router, and a regional IP/MPLS core router with integrated 100GbE coherent transport for superior performance, operators can tune their network infrastructure through proactive monitoring and what-if planning capabilities. The NorthStar Controller dynamically creates explicit routing paths using a global view based on user-defined constraints to create a fully autonomous operation.
Scale is one of the guiding design principles for the PTX Series routers, allowing network operators to smoothly handle increased traffic demands. The PTX Series fixed-configuration routers simplify network engineering challenges with predictable system latency, improving the overall service experience by delivering best-in-class resiliency to help providers meet strict customer service-level agreements (SLAs).
Operational efficiency is another design attribute for the PTX Series routers, focusing on power, space, and weight—fundamental concerns that affect network operators’ operational budgets. Juniper has designed the PTX Series to fit the requirements of current and future data center facilities.
SDN programmability brings virtual innovations to the service provider core, while the NorthStar Controller offers an open, standards-based solution that optimizes both the IP layer and the transport layer with precise SDN control, allowing network operators to fully automate and scale their operations with ease.
