Cisco XR 12000 Series and Cisco 12000 Series Routers
The Cisco® XR 12000 Series and Cisco 12000 Series routers compose a portfolio of intelligent routing solutions that
scale from 2.5- to n x10 Gbps capacity per slot, enabling carrier-class IP/Multiprotocol Label Switching (MPLS)
networks and accelerating the evolution to IP Next-Generation Networks. Built upon a foundation of investment
protection, this portfolio delivers up to 1.28-terabits-per-second switching capacity with wire-speed feature
performance, scalability, and graceful hardware and software upgrade paths.
CISCO XR 12000 AND 12000 SERIES PRODUCT PORTFOLIO OVERVIEW
This portfolio of routers delivers capacity and services with its fully distributed forwarding architecture and high-efficiency crossbar switch
fabric (Figure 1). The combination of a centralized scheduler and unique virtual output queuing (VOQ) technology is aimed at maximizing
the use of the switch fabric bandwidth, minimizing latency, and providing nonblocking performance. Cisco Systems® uses the latest in
high-performance application-specific integrated circuit (ASIC) technology to provide line-rate forwarding with an extensive feature set,
while maintaining the strict control of jitter and latency required for real-time services. Offering a comprehensive set of quality-of-service
(QoS), IP/MPLS, and high-availability features, the Cisco XR 12000 Series and 12000 Series routers can help ensure maximum bandwidth
usage and traffic differentiation while meeting even the strictest customer service-level agreements (SLAs).
The Cisco XR 12000 Series and 12000 Series routers use Cisco IOS® XR Software and Cisco IOS Software, respectively, to deliver
numerous service possibilities for network operators. With the addition of the Cisco XR 12000 Series to its high-end routing product lines,
Cisco Systems gives providers a graceful upgrade path for their installed base of Cisco 12000 Series routers as they transition toward a
converged IP Next-Generation Network infrastructure. For a detailed list of feature support, software capabilities, compatibility, and
