Cisco Performance Routing Engine 2 for the Cisco uBR10012 Router [Cisco Route Processors and Route Switch Processors]

DATA SHEET

Cable operators are generating significant revenue and earnings growth with new service offerings that lead the market in terms of features and benefits, performance, service availability, and operational efficiency. The Cisco® Performance Routing Engine 2 (PRE-2) is the next-generation route processor for the Cisco uBR10012 Universal Broadband Router that addresses emerging service needs. It offers cable operators the combined advantages of high performance, an unmatched Layer 3 feature set, scalability, as well as high availability for their IP-centric cable modem and set-top based applications.

PRODUCT OVERVIEW

The Cisco PRE-2 (Figure 1) evolves the cable IP network with superior performance and reliability. The Cisco PRE-2 performs Layer 2 and Layer 3 packet processing, 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). The Cisco PRE-2 introduces support for full-duplex Gigabit Ethernet ports and increases the supported connections to 1.6 Gbps in full duplex (each direction per half slot). Full-slot modules can now have up to 3.2 Gbps to and from the Cisco PRE-2-twice the connection rate of the Cisco PRE-1. Two Cisco PRE-2 modules can be installed for redundancy.

Cisco Performance Routing Engine 2 (PRE-2) for the Cisco uBR10012 Universal Broadband Router

The Cisco uBR10012 is a communications-grade cable modem termination system (CMTS) that offers an unmatched feature set for DOCSIS®-based cable modem and set-top box applications. With full Layer 3 routing capability and industry-leading capacity, the Cisco uBR10012 supports deployment of next-generation cable IP services that require a greater level of intelligence and processing power. With the Cisco PRE-2, the Cisco uBR10012 now supports a minimum of 64,000 subscribers.

The Cisco PRE-2 exploits the latest Cisco Parallel Express Forwarding (PXF) patented technology for unparalleled performance and scalability. Cisco PXF is a parallel multiprocessor architecture that helps enable deployment of multiple IP services while maintaining peak performance throughput.

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

FEATURES AND BENEFITS

Table 1 gives more details about the features and benefits of the Cisco PRE-2.

Table 1. Features and Benefits of Cisco PRE-2

Features	Benefits
Up to 6.2 mpps of processing capability	This processing capability delivers line-rate performance, with a wide variety of features enabled. Customers providing DOCSIS-based high-speed data, PacketCable voice over IP (VoIP), DOCSIS Set-Top Gateway (DSG) video transport, and other leading-edge IP services require exceptional processing capability to support these new revenue-generating services.
Up to 6.4-Gbps full duplex per WAN and 3.2-Gbps full duplex per RF slot backplane support	This feature provides a balance packet flow between ingress and egress slot capacity, offering a total capacity of >24-Gbps full duplex.
Cisco PXF patented technology	Cisco PXF delivers increased performance and flexibility. Using Cisco PXF, the Cisco uBR10012 helps enable cable operators to turn on multiple services without experiencing performance degradation-crucial when operators deploy new types of services. Cisco PXF is a software-based technology that helps enable the Cisco uBR10012 to implement new services without upgrading hardware, thereby providing investment protection and saving customers time and money.
Processor redundancy	Processor redundancy helps enable 99.999-percent network uptime, particularly important when supporting primary line voice services. Each Cisco uBR10012 chassis supports up to 2 Cisco PRE-2 modules for redundancy. Architected to support 99.999-percent uptime and coupled with a superior set of high-availability features and functions, the Cisco uBR10012 is the industry's leading carrier-class CMTS.
500-MHz RISC processor handling route and SNMP processing	This feature offers co-processor (in addition to the 64 microcores in the Cisco PXF complex) capacity for managing thousands of routes and management requests.

SOFTWARE FEATURES

With Cisco PXF, the Cisco PRE-2 separates control-plane functions from data-plane functions. A general-purpose RISC processor (500 MHz RM7000 mips) supports control-plane functions of administration, route processing, management, and configuration. Multiple Cisco PXF network processors support data-plane functions-including high-performance Layer 3 forwarding. The combination of a general-purpose RISC processor with advanced programmable Cisco PXF network processors provides maximum flexibility while maintaining maximum throughput of essential IP services such as quality of service (QoS), Multiprotocol Label Switching (MPLS), and access policy filtering.
