CISCO PERFORMANCE ROUTING ENGINE 2 FOR THE CISCO uBR10012
UNIVERSAL BROADBAND ROUTER
UNIVERSAL BROADBAND ROUTER
OVERVIEW
Cisco Systems
®
is pleased to announce the new Cisco
®
Performance Routing Engine 2 (PRE-2) for the Cisco uBR10012 Universal
Broadband Router. This component offers increased performance and processing power needed to support next-generation IP data, voice,
and video services over cable.
The Cisco PRE-2 performs Layer 2 and Layer 3 packet processing for the Cisco uBR10012, as well as routing and system management
functions. It effectively doubles the bandwidth available to each slot on the Cisco uBR10012 as supported by cable interface line cards or
Cisco broadband processing engines (BPEs) over the Cisco PRE-1. The Cisco PRE-2 continues to use an advanced parallel architecture
called Cisco Parallel Express Forwarding (PXF), which separates control-plane processing from the data plane. The Cisco PXF
architecture supports high-performance throughput with IP services enabled on every port.
The Cisco PRE-2 offers the following features:
•
Processes up to 6.2 million packets per second (mpps) and eight concurrent flows in the Cisco uBR10012
•
Supports up to 6.4-Gbps full duplex per WAN and 3.2-Gbps full duplex per RF slot
•
Uses Cisco PXF patented technology to provide maximum IP services performance
•
Supports processor redundancy, helping enable 99.999-percent network uptime
•
Offers 500-MHz Reduced Instruction Set Computer (RISC) processor handling route and Simple Network Management Protocol
(SNMP) processing
