Performance Routing Engine

Overview

The Cisco 10000 Edge Services Router (ESR) Performance Routing Engine (PRE) delivers the most advanced processing hardware technology with proven Cisco IOS software to power a new generation of Cisco 10000 high-performance switching routers. Designed to address Internet service provider (ISP) requirements for high-capacity, leased-line aggregation with sophisticated IP services enabled, the PRE implements a unique distributed, parallel processing architecture based on a new forwarding paradigm called Parallel eXpress Forwarding (PXF). PXF enables the Cisco 10000 ESR to support an unprecedented number of leased-line connections with high-performance IP services on every connection. At last, ISPs have a multilayer switch and router engine capable of supporting consistent, high-performance throughput with IP services enabled allowing ISP service differentiation and new revenue generation in the exploding dedicated leased-line aggregation market.

Product Description

The PRE is a single-slot module for the Cisco 10000 ESR. Multiple PREs can be configured in a single chassis for redundancy. The PRE does all Layer 2 and Layer 3 packet manipulation related to routing and forwarding through the Cisco 10000 ESR. It includes an advanced parallel processing architecture called Parallel eXpress Forwarding (PXF) to support high-performance throughput with IP services enabled on every port. The Cisco 10000 ESR PRE runs a Cisco IOS 12.0S-based release, contains two PCMCIA slots, 32 MB of FLASH memory, a 128 MB packet buffer, and supports up to 512 MB of SDRAM.

The Cisco 10000 ESR PRE module combines efficiency with performance. By centralizing all Layer 2 and Layer 3 processing in one module, the Cisco 10000 ESR PRE makes maximum use of available processing capacity for any given task. Performance is optimized by a unique distributed parallel processing architecture that separates the control plane from the data plane to deliver unequaled performance. A general-purpose RISC processor (262-300 MHz MIPS RISC Mark RM7000) supports control plane functions of processing switching and administration and configuration. PXF Network Processors (very advanced programmable devices optimized for high-speed deployment of IP services) are on the data plane and support high-performance Layer 3 forwarding of traffic. The combination of a general purpose RISC processor with advanced programmable PXF Network Processors provide the capacity to support the aggregation of thousands of leased-lines in a single Cisco 10000 ESR chassis with important

IP services such as access policy filtering, rate-based queuing, and quality of service (QoS) enabled on every line.
