PTX12008 8-SLOT CHASSIS

Changing market dynamics intensify the challenge of accommodating growth with traditional WAN routers and architectures. PTX12000 line addresses the requirements of high-density 800GbE now and 1.6TbE-based network infrastructure in future. The line of modular routers delivers high performance, next-generation modular systems based on our fifth-generation silicon. The PTX12000 provides a high-density, power-efficient solution with OSFP and QSFP 800GbE ports, along with advanced features such as SRv6, HQoS, BIER, and INT-MD. Designed to reduce operators' total cost of ownership (TCO), the PTX12000 offers a highly flexible, high performance, and sustainable platform built for longevity in the most demanding environments.

The PTX12000 line provides industry-leading 800GbE port density in an 8-slot and 12-slot chassis and lays the foundation for the next generation of PTX platforms based on our Express silicon. Each line card delivers a forwarding capacity of 43.2 Tbps, powered by the Express 5 series ASIC.

The PTX12000 line supports a wide range of mission-critical network roles-including core, peering, data center interconnect and edge, metro aggregation, and AI data center networking-for service providers, cloud operators, and enterprise networks. With its modular architecture and precise traffic control capabilities, the PTX12000 line empowers you to develop and deliver new services anywhere in the network without compromising performance or service quality.

The PTX12000 line is powered by the highly scalable, next-generation ASIC in the Express silicon family. Our Express 5 silicon brings industry-leading in-line MACsec (port based and VLAN based) for all 800GbE interfaces at line rate and delivers with low latency, 8M counters, 10M+ FIB, 100,000+ SR tunnels, 256 AES MACsec encryption supported on all ports, and wire-rate packet performance for IP traffic.

The PTX12000 line delivers massive scalability, flexibility, and reliability to help network operators overcome key network challenges related to scale, agility, and investment protection. The key challenges operators face are as follows:

Scale: Providers offer backbone connectivity over a network that requires a large number of label-switched paths (LSPs), whether they are using Segment Routing v6 (SRv6) or RSVP to take advantage of traffic engineering (SR-TE/RSVP-TE) functionality. The control plane signaling path must be able to scale in step with the growth of LSPs. This ability is necessary for primary and backup paths to scale and to support resiliency with fast reroute (FRR) and topology independent loop-free alternates (TI-LFA). In modern networks, the total number of paths needed for backbone connectivity may be several million-presenting a daunting scaling challenge for operators trying to diversify their portfolios by adding a broader scope of connectivity services to cloud or between clouds, or connecting enterprises over VPNs or private lines.

Operational flexibility: Virtualized services and the explosion of cloud-based applications are creating increasingly complex traffic patterns. To handle this complexity, service providers need architectures that are flexible and dynamic across all layers.

Investment protection: Helping ensure operators are investing in platforms designed to last has become imperative, and it requires leveraging the next generation of industry-leading ASIC improvements. Rip-and-replace strategies and yearly upgrades pose an unacceptable risk to service continuity and network profitability.
