The unique ASICs family eliminates unnecessary complex packet profiles found in elaborate, over-engineered network processing units required by other core routers.

The PTX10000 line brings physical and virtual innovations to provider networks. These next-generation routers help network operators achieve their business goals while effectively handling current and future traffic demands through automation, optimization, and programmability.

The PTX10000 line combines the best of Juniper’s Express ASICs with the reliability and familiarity of Junos^® OS Evolved and the flexibility of a Linux kernel. PTX 10000 routers are comprised of feature-rich, 800GbE-optimized fixed and modular platforms.

The PTX10004 (4-slot), PTX10008 (8-slot), and PTX10016 (16-slot) modular routers utilize Juniper’s Express 4 and Express 5 ASIC-powered line cards that support deep buffers, flexible packet filtering, and bandwidth-demanding WAN and data center architectures.

The PTX10004, PTX10008, and PTX10016 routers are cloud-scale platforms designed to enable the transition and expansion of dense 400GbE and 800GbE networks. These high-density routers are designed for today’s space and power-constrained facilities, supporting line-rate inline Media Access Control Security (MACsec) on all ports up to 800GbE for uncompromised security.

For low bit-rate applications such as 10GbE or 25GbE, PTX10000 line cards offer native SFP+ and SFP28 transceivers support through QSFP adapters: MAM1Q00A-QSA and MAM1Q00A-QSA28. This option enables deployments where 10GbE or 25GbE connectivity over more than 10KM single mode fiber links are required.

These flexible, versatile, and modular routing platforms enable network engineers to build WAN and data center architectures for several distinct roles:

• Core: The PTX10000 line allows service providers and cloud providers to build a massively scalable core with hundreds of thousands of LSPs. The routers support seamless transition expansion to 400GbE and 800GbE and conversions from traditional to innovative architectures without forklift upgrades or service disruptions.
• Peering: The PTX10000 line is ideal for scaled-up and scaled-out peering deployments with full traffic visibility using 8M+ counters, high RIB and FIB, NS BGP at scale, encapsulated IP filtering, sampling, port mirroring, and DDoS detection with flexible offset filters (Express 5 only) and Corero.
• Data Center Edge: The PTX10000 line provides an agile, pay-as-you-grow approach to ever-increasing bandwidth requirements for the data center edge in the era of cloud-scale networking. With a choice of various overlays and underlays, it is an essential building block of a flexible data center edge solution supporting: EVPN, VXLAN, MPLS, and expansion to innovative data center technologies, such as multicast (VXLAN OISM) and more.
• Data Center Interconnect (DCI): The PTX10000 line is an excellent data center interconnect modular routing platform with advanced EVPN-VXLAN feature-set for data center-to-data center connectivity. The routers have a comprehensive set of features such as ECN, PFC, etc. tailored for interconnecting AI/ML clusters across data centers. In-line MACsec encryption at line-rate ensures that the connection is secure, without compromising the forwarding performance or latency.
• Metro Aggregation: With advanced Layer 2/3 services enabled by Express 5 silicon, the PTX10000 line is well suited for metro aggregation roles. These capabilities are complemented by rich-OAM (Y.1731), MC-LAG, H-QoS, BIER, and an industry leading scale of SRv6 uSIDs.
• AI Data Center Networking: The PTX10000 line provides the highest radix designs with deep buffers, and a cell-based switch fabric makes it ideal for 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, and more.

Continuous innovations in silicon enable the PTX10000 modular routers to accommodate scale-up and scale-out architectures with smooth migration paths as traffic patterns change. Juniper’s custom Express silicon allows adaptive load balancing, data structure sharing, better resource utilization, as well as value-added resources for filtering flexibility—all while lowering cost-per-bit with improved space and power utilization.

The PTX10004, PTX10008, and PTX10016 are powered by the highly-scalable Juniper Express 5 silicon brings industry-leading inline MACsec for all 36x800GbE interfaces at line rate via universal multi-rate QSFP-DD, including dual-LC connectors to operate 72x400GbE mode in dense 400GbE deployments. The Juniper Express 5 silicon delivers consistent low latency, 8M counters, 256 Advanced Encryption Standard (AES) MACsec supported on all ports, and wire-rate packet performance for IP traffic without sacrificing the optimized system power profile. Juniper Express 5 silicon incorporates a high-bandwidth memory (HBM) 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 to gain massive IP routing scale, while delivering power efficiency gains.

MicroSID (uSID) technology enhances SRv6 forwarding by reducing the overhead associated with transporting the SID list and by compressing multiple SIDs into a single IPv6 address (128 bit). This provides a scalable and deterministic traffic-engineered forwarding plane to support a broad spectrum of core, peering, metro, and data center use cases. Express 5 silicon-based line cards provide the highest scale of SRv6 uSIDs in the industry, enabling seamless transitions for existing PTX10000 customers and an agile network infrastructure in new PTX10000 deployments.

The ability to address a provider’s WAN transport requirements—scale, operational flexibility, sustainability, and SDN control—begins with advanced silicon capabilities. Juniper Express 5 optimally addresses these emerging infrastructure needs.

The PTX10000 line features several key architectural elements that deliver superior resiliency. Dual redundant routing engines (REs) on the PTX10004, PTX10008, and PTX10016 run the Junos OS Evolved operating system, where they manage all routing protocol processes, router interface control, and control plane functions such as chassis component, system management, and user access to the router. In addition, a unique cryptographic digital identity has been added to the Trusted Platform Module (TPM 2.0), which is embedded in the latest generation of REs. This addition enables device attestation and enhances security. REs’ processes interact with the Packet Forwarding Engine (PFE) on the line cards via dedicated high-bandwidth management channels, providing a clean separation of the control and forwarding planes.

The PTX10004, PTX10008, and PTX10016 Express silicon-based line cards currently support 10GbE, 25GbE, 40GbE, 100GbE, 400GbE, and 800GbE interfaces. The horizontal line cards in the front of the chassis connect directly to the vertical switch fabric cards in the rear of a chassis via orthogonal interconnects without requiring a midplane. This provides unparalleled investment protection by ensuring a smooth upgrade path to higher speed switch fabric cards as they become available. The midplane-less design improves airflow with a front-to-back design and enables limitless scale.

To maintain uninterrupted operation, the PTX10000 modular chassis fan trays cool the line cards and REs with redundant, variable-speed fans. In addition, the power supplies in the PTX10000 line convert building power to the internal voltage required by the system. All PTX10000 line components are hot-swappable, and all central functions are available in redundant configurations, providing high operational availability by allowing continuous system operation during maintenance or repairs.

Key hardware components of the PTX10004, PTX10008, and PTX10016 modular routers include the switch fabrics, REs, and line cards.Key hardware components of the PTX10004, PTX10008, and PTX10016 modular routers include the switch fabrics, REs, and line cards.

The line cards also support native MACsec without compromising throughput on any supported interface rated up to 800GbE, providing point-to-point security on Ethernet links. MACsec blocks security threats such as DoS, intrusion, man-in-the-middle, masquerading, passive wiretapping, and playback attacks while securing links for most traffic frames from the Link Layer Discovery Protocol (LLDP), Link Aggregation Control Protocol (LACP), Dynamic Host Configuration Protocol (DHCP), Address Resolution Protocol (ARP), and others. All ports can support 800GbE ZR and ZR+ optics, making it ready for converged optical routing architectures without compromising port density.

The PTX10004 has three power supply slots, the PTX10008 offers six power supply slots, and the PTX10016 has 10 power supply slots, providing complete flexibility for provisioning and redundancy. Each power supply has its own internal fan for cooling. The PTX10000 line supports both AC and DC power supplies; however, AC and DC supplies cannot be mixed in the same chassis. The second and third generation is designed to support both Express 4 and Express 5 line cards. The AC2 and AC3 power supplies of PTX10000 line routers are high-capacity, high line-voltage models designed to operate with either standard-voltage AC, high-voltage AC (HVAC), or high-voltage DC (HVDC) systems. The AC2 power supplies convert an input voltage between 180VAC to 305 VAC and provide 12.3V DC output, delivering 5000 watts with a single feed and 5500 watts with a dual feed. Built on a single housing platform, the DC power supplies consist of two DC power modules that take 190 VDC to 410 VDC line input via four redundant input power feeds at 60A or 80A.

The PTX10000 line supports front-to-back cooling with air drawn in through the perforations on the REs and the line cards in the front of the platform. The fan trays are in front of the fabric cards and are accessible from the rear of the chassis. Hot air exhausts through the rear of the chassis.

The PTX10000 line delivers powerful Junos OS Evolved chassis management that allows environmental monitoring and field-replaceable unit (FRU) control. Chassis management provides a faster primary switchover, enhanced power budgeting with a modular power management, automatically reduced power consumption for partially populated systems, granular control over FRU power-on, adaptive cooling, and CPU leveling during monitoring intervals.

PTX10000 line routers simplify management based on the elegance and simplicity of Junos OS Evolved. Network management applications and tools can configure and/or receive streaming telemetry data using native, OpenConfig, and IETF data models, offering robust protocol analytics for any SDN environment. Junos OS Evolved provides inherent resilience, operational uniformity, and the adaptability required to advance your network. To enable dynamic control and management of network devices through a unified and standardized interface, PTX10000 platforms powered by Junos OS Evolved also support P4 Runtime (P4RT), which empowers the network operating systems with unprecedented flexibility and programmability.
