CRS-X: Intelligence and Speed

Cisco Carrier Routing System powers some of the world's largest service provider networks.

CRS-X: Intelligence and  Speed

Simplify Core Networks
Today’s customers expect more from service providers. In addition to traditional connectivity services, customers demand video, voice, VPNs, and IP-rich media content delivery. To meet these demands while controlling costs and optimizing efficiency, you need to converge your core network infrastructure to a Cisco Evolved Programmable Network (EPN).

The Cisco EPN:

  • Simplifies architecture for core networks
  • Reduces capital and operating expenses
  • Helps you deliver current services more efficiently
  • Provides scalability and capacity for exponentially growing, bandwidth-intensive broadband services

By adopting a Cisco EPN framework with an intelligent, scalable Cisco IP/MPLS core routing solution, you can realize the full benefit of next-generation services.

Carrier Routing System for Core Networks
The Cisco Carrier Routing System (CRS) series provides industry-leading performance, advanced services intelligence, environmentally conscious design, and system longevity. Each model uses Cisco IOS XR Software, a unique self-healing, modular, distributed operating system. Models include the following:

  • Cisco CRS-3, powered by Cisco QuantumFlow Array, offers from a single-chassis to a multichassis system up to 322 Tbps.
  • Cisco CRS-1, built on the Cisco Silicon Packet Processor, offers from a single-chassis to a multishelf system up to 92 Tbps.

The Cisco CRS-3 helps carriers build a foundation for the next-generation Internet. Video, mobility, and data center cloud services are accelerating bandwidth needs and creating dynamic, multidirectional traffic patterns. Cisco CRS-3 offers customers one converged network to address these challenges.


Cisco CRS-3 is the industry's only router that combines:

  • Unmatched multichassis scale (up to 322 Tbps)
  • Unique core and data center cloud service attributes
  • Exceptional savings

Powered by the Cisco QuantumFlow Array, the CRS-3 helps carriers capture growth in video, mobile, and data center cloud services.
