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
