Data Sheet

Cisco 10000 Series Performance Routing Engine

Service providers, particularly for the network edge, face the challenges of the ever-growing demands on scaling, performance, service availability, and operational cost reductions. The Cisco® 10000 Series Performance Routing Engine (PRE-2) is the next-generation route processor for the Cisco 10000 Series. It offers service providers the combined advantages of high performance, rich features, scalability, as well as high availability for their edge aggregation applications (Figure 1).

Product Overview

The Cisco 10000 Series is a service provider edge aggregation router that offers a single solution for leased-line, ATM, Frame Relay, and broadband aggregation while providing customers with high-performance IP services, maximum platform scalability, and high availability.

Designed to address Internet-service-provider (ISP) requirements for high-capacity, leased-line aggregation, as well as broadband aggregation with sophisticated IP services, the Cisco PRE-2 uses the Cisco patented Parallel Express Forwarding (PXF) technology. PXF is a parallel multiprocessor architecture that enables deployment of multiple IP services while maintaining peak performance throughput.

Benefits of the Cisco 10000 Series PRE-2 include:

  • Provides up to 6.2 mpps of processing power in the Cisco 10000 Series
  • Backplane supports up to 6.4 Gbps duplex per slot
  • Uses Cisco patented PXF technology to provide maximum IP services performance
  • Supports processor redundancy— for enabling 99.999-percent network uptime

Features and Benefits Overview

Table 1 lists the features and benefits of the Cisco 10000 Series PRE-2.

Table 1   Features and Benefits of Cisco 10000 Series PRE-2

Features Benefits
Provides up to 6.2-mpps processing

Customers aggregating leased lines, ATM, Frame Relay, and broadband aggregation traffic require line-rate performance with a wide variety of features enabled. The Cisco 10000 Series with PRE-2 provides the IP services and performance that service providers require when deploying new revenue-generating services.

Uses Cisco patented PXF technology to provide maximum IP services performance

PXF technology provides the Cisco 10000 Series with performance and flexibility. Using PXF, the Cisco 10000 Series enables service providers to turn on multiple services without experiencing performance degradation. This is crucial when service providers look to upsell customers to new types of services. In addition, PXF is a software-based technology that enables the Cisco 10000 Series to implement new services without upgrading hardware—thereby providing investment protection and saving customers time and money.

Supports processor redundancy—for enabling 99.999-percent network uptime

Each Cisco 10000 chassis supports up to 2 PRE-2s for redundancy. Architected to support 99.999-percent uptime and coupled with a superior set of high-availability features and functions, the Cisco 10000 Series is the industry's leading carrier-class edge aggregation platform.

Software Features

Through the use of PXF, the Cisco 10000 Series PRE-2 separates control-plane functions from data-plane functions. A general-purpose Reduced Instruction Set Computer (RISC) processor (500-MHz mips RM7000) supports control-plane functions of packet switching, administration, and configuration.

Multiple PXF network processors support data-plane functions—including high-performance Layer 3 forwarding. The combination of a general-purpose RISC processor with advanced programmable PXF network processors provides maximum flexibility while maintaining maximum throughput of essential IP services such as quality of service (QoS), Multiprotocol Label Switching (MPLS), and access policy filtering.
