Cisco CRS-8-PRP-6G Network Interface Processor Networking

The Cisco® Carrier Routing System (CRS) performance route processors provide speed and scale for the evolving needs of the network. The Cisco CRS route processor comes with the speed of the Intel® Xeon® dual-core processor and has 6 or 12 GB of double data rate type three (DDR3) error-correcting code (ECC) memory for fast routing performance and 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 processors (Figures 1 and 2) run on Cisco IOS® XR Software, a fully modular and 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.
