Cisco CRS 16-Slot Line Card Chassis
Performance Route Processor

Product Overview

The Cisco

Carrier Routing System (CRS) Performance Route Processor is the next-generation route processor

for the Cisco CRS-1, CRS-3, and CRS-X platforms. It is the first Cisco CRS Route Processor to offer the

outstanding speed of the Intel

Xeon

quad-core processor. With 6 or 12 GB of double-data-rate 3 (DDR3) error-

correcting code (ECC) memory, this performance route processor provides extremely fast routing performance at

exceptional scale for the largest core and edge applications. The multicore design and speed allow you to achieve

high scaling levels for applications such as Border Gateway Protocol (BGP) and Interior Gateway Protocols (IGP),

Multiprotocol Label Switch Traffic Engineering (MPLS-TE), Cisco NetFlow, Lawful Intercept, Simple Network

Management Protocol (SNMP), or Extensible Markup Language (XML) monitoring, without adversely affecting

routing performance.

The Cisco CRS Performance Route Processor (Figure 1) uses the award-winning Cisco IOS

XR Software, which

is a fully modular, fully distributed internetwork operating system that uses a memory-protected, microkernel-based

architecture and control-plane distribution that allow the system to scale.

The performance route processor also includes a pair of solid-state drives (SSDs) for fast software installation and

boot-up. Like the ECC memory, which protects against memory errors, the dual SSDs guard against drive failure

by mirroring the boot partition that stores the Cisco IOS XR Software.
