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
ATM service examples include:
• Class - Multiple packet queues for data, voice, or video
• Logical - ATM VCs (virtual circuits) grouped by Gold, Bronze, or Silver packages for bandwidth and QoS levels
• Physical - ATM Virtual Paths (VPs) to separate consumer, business, and wholesale customers
