Cisco 10000 Series Performance Routing Engine 3

The Cisco® 10000 Series Performance Routing Engine 3 (PRE-3) (Figure 1) increases

the performance, feature set, and scalability of the Cisco 10000 Series Router.

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.

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, will be 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 PRE-3 uses the latest generation of the Cisco

patented Parallel Express Forwarding (PXF) technology. PXF is a parallel multiprocessor

architecture that helps enable deployment of multiple IP services while maintaining peak

performance throughput. The PRE-3 also introduces the Hierarchal Queuing Framework (HQF) to

the Cisco 10000 Series Routers. The HQF implementation on the PRE-3 allows three levels (class,

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

Applications

The Cisco 10000 Series PRE-3 can be used to deliver triple-play services for both ATM and

Ethernet transport networks. A service provider can use the flexibility and performance of the PRE-

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

Ethernet service examples include:

●Class – Multiple packet queues for data, voice, or video

●Logical – PPP sessions grouped by Gold, Bronze, or Silver packages for bandwidth and

quality of service (QoS) levels

●Physical – VLANs to separate consumer, business, and wholesale customers
