ESR-PRE4 Preformance Routing Engine 4 IPUCAM3BAC
Cisco 10000 Series Performance Routing Engine 4
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.
Ethernet service examples include:
• Class - Multiple packet queues for data, voice, or video
• Logical - PPP or IP sessions grouped by Gold, Bronze, or Silver packages for bandwidth and QoS levels
• Physical - QinQ or dot1Q VLANs to separate consumer, business, and wholesale customers
ATM service examples include:
• Class - Multiple packet queues for data, voice, or video
• Logical - ATM virtual circuits grouped by Gold, Bronze, or Silver packages for bandwidth and QoS levels
• Physical - ATM virtual paths to separate consumer, business, and wholesale customers
