Cisco 10000 Series Performance Routing Engine 4

The Cisco® 10000 Series Performance Routing Engine 4 (PRE4) (Figure 1) addresses

the demand for increased performance, scalability, and hierarchical quality of service

(HQoS) to support diverse network-edge requirements for residential and business

services markets.

Product Overview

The Cisco 10000 Series is a Service Provider edge aggregation router that offers a single solution

for the diverse requirements of broadband aggregation, leased-line, Ethernet, ATM, and Frame

Relay services. The Cisco 10000 Series provides customers with superior price/performance,

industry-leading IP services, maximum platform scalability, and high availability.

Service providers require scalable networks to profitably meet their customers' requirements for

better performance, more services, and higher reliability. Edge routers, such as the Cisco 10000

Series, are needed to manage higher-bandwidth requirements, more subscribers, and multiple

service levels ranging from best-effort consumer Internet data services to high-priority business

applications, voice, and video.

Designed to meet new requirements from service providers for high-capacity aggregation with

sophisticated IP services, the Cisco 10000 Series PRE4 uses the latest generation of 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. The PRE4 also supports the flexible Hierarchal Queuing Framework (HQF) available

on the Cisco 10000 Series Routers. The HQF implementation on the PRE4 allows three levels

(class, logical, and physical) of scheduling to apply queuing and shaping (see Figure 2).

Applications

The Cisco 10000 Series PRE4 can be used to deliver triple-play services for both Ethernet and

ATM transport networks. A service provider can use the flexibility and performance of the PRE4 to

simultaneously deliver data, voice, and video to both residential and business customers.
