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.
