New traffic dynamics such as mobile, 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 increase under the burden of these growing traffic volumes. Cloud and service providers need to become more agile to optimize their existing network resources, shorten planning cycles, and remove rigid network layers.

Operators are facing multiple challenges in the current environment:

• Static scale: Provider and enterprise network backbones handle the full weight of network traffic. It is paramount that core networks are inherently designed for scalability and efficiency. This 800GbE-capable platform, with 10/40/100/400/800GbE inline MACsec, empowers network operators to maintain pace with traffic growth incrementally with an elegant, elastic, redundant ultra-compact router.
• Static architecture: Virtualized services and the explosion of cloud-based applications are creating increasingly unpredictable traffic patterns. To handle this unpredictability, service providers need an adaptable platform like the PTX10002-36QDD that scales across the WAN transport in a plethora of roles with flexible programmability to support any service, anywhere.
• Power costs: With the ever-increasing bandwidth demands and associated power utilization projected for WAN routing, power efficiency is of paramount concern. Leading the industry with Express 5 silicon’s unparalleled power efficiency, the PTX10002-36QDD minimizes your environmental footprint while maximizing performance by integrating 36x 800GbE or 72x 400GbE interfaces through dual-LC connectors in a compact 2U form factor. This significantly reduces power costs and advances sustainability objectives including space and carbon footprint.
• 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. The PTX10002-36QDD is designed with sustainable efficiency to operate under space and resource constrained environments.

The PTX10002-36QDD brings physical and virtual innovation to provider and enterprise WAN networks. This router streamlines integration and deploys seamlessly in existing 400GbE WAN environments with a dense 72x 400GbE interface configuration through 2x 400GbE dual LC or dual-CS connectors. The PTX10002-36QDD fixed-configuration router provides an extensible platform to scale-out provider and enterprise WAN backbone architectures, ensuring a consistent user experience across geographies. The PTX10002-36QDD meets all existing core, peering, Data Center Interconnect (DCI), data center edge, metro aggregation, and AI data center networking requirements, easily fitting into provider and enterprise networks in multiple mission critical roles, including:

• Core routing: The PTX10002-36QDD employs a massively scalable yet compact U form-factor with scalable BGP, filters, and security with 8M Counters; encapsulated IP filtering, sampling, port mirroring; and >200K Transit LSP.
• Peering: The PTX10002-36QDD is perfect to scale-out peering in space and power-constrained environments with full traffic visibility and L3 services including advanced scale and security; filters, RIB/FIB, NS BGP at scale; 8M counters; encapsulated IP; filtering, sampling, and port mirroring; DDoS detection with flex filter offset and Corero mitigation. The compact PTX10002-36QDD offers high routing scale for full traffic statistics visibility and deep buffers.
• Data center edge: The PTX10002-36QDD is also a flexible data center edge solution supporting: EVPN/VXLAN /MPLS, expansion to innovative data center technologies, multicast (VXLAN OISM), stitching, and more.
• DCI: The PTX10002-36QDD is an excellent data center interconnect router with advanced EVPN, VXLAN, and data center connectivity including: EVPN/VXLAN, ECN/PFC, and in-band telemetry. The PTX10002-36QDD offers secure inline MACsec with no compromise in throughput or latency, an extended range enabled by 400GbE ZR/ZR+ and 800GbE optics, and hardware readiness for 800GbE ZR/ZR+ optics.
• Metro aggregation: With advanced L2/L3 services the compact PTX10002-36QDD is also well suited for metro aggregation roles including: CFM/LFM – Y.1731; MC-LAG; hierarchical QoS; BIER; SRv6.
• AI data center networking: The PTX10002-36QDD also offers a high radix routing platform with deep buffers and a cell-based switch fabric making it a superior spine or leaf in AI data center networking environments. AI data center networking capabilities include efficient, deep-buffered interfaces, scalable cell-based fabric design, VOQ scheduling, RoCEv2, Adaptive Load Balancing, 8M Counters, built-in IPFIX and INT-MD, and more.

Physical innovations at the silicon level enable the PTX10002-36QDD fixed-configuration router to boost industry-leading performance and throughput efficiency numbers at optimal power efficiency.

The PTX10002-36QDD is powered by the highly scalable, next-generation ASIC in the Express silicon family. Juniper Express 5 silicon brings industry-leading inline MACsec (port based and VLAN based) for all 800GbE interfaces (28.8 Tbps encryption/decryption per chip) with universal multi-rate QDD800 and QSFP56-DD. Juniper Express 5 silicon delivers consistent low latency, 8M counters, 10M-plus FIB, 100,000-plus SR tunnels, 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 previous generation Express silicon family, Juniper Express 5 silicon incorporates 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 <0.05 Watts/Gig.

Performance is one of the guiding design principles for the PTX Series Packet Transport Routers. This focus empowers providers and enterprise customers with superior scale to match increased traffic levels and network engineering challenges with predictable system latency. Ultimately, this improves the overall service experience, delivers best-in-class resiliency, and ensures that services meet strict customer SLAs.

Operational cost efficiency is the other guiding design principle for the PTX Series routers, focusing on power, space, and weight — fundamental concerns that impact service providers’ operational budget with respect to growing traffic. Elevating the standard for power efficiency, the PTX10002-36QDD not only seamlessly supports 800G ZR and ZR+ in every port but also implements industry-leading, power-saving measures. Tailoring its power consumption to specific use cases, it features automatic shutdown capability for unused packet forwarding engines (PFEs), MACsec engines, and more. Additionally, the router integrates environmental management policies for optics, ensuring that components like fans operate at optimal speeds based on the specific optics in use.

Infinite programmability with automation and telemetry brings virtual innovations to the cloud and service provider core, while Juniper Paragon Pathfinder , an open, standards-based solution optimizes both the IP layer and the transport layer with simplicity and precision. Paragon Pathfinder (formerly NorthStar Controller) is a cloud-native SDN controller that simplifies traffic engineering, making it easier for you to leverage benefits provided by transport service paths, such as MPLS/RSVP, segment routing , and network slicing.
