Cisco CRS 4/8-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 all Cisco CRS four-slot and eight-slot platforms. It is the first Cisco CRS route processor to offer the speed of

the Intel

Xeon

dual-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 all

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 Mark-up 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 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.
