PRS 5G and PRS 20G

Switch Fabric

PRS Q-64G high-end switch devices.

The PRS 5G and PRS 20G devices can

operate as either switching devices

located on user cards of

smaller-capacity systems, or switch

fabric interface devices of user cards

connected to the PRS central switch of a

high-end system. Known as PRS C48X

and PRS C192X when used as fabric

interfaces, these devices address the

scalability needs of product lines that

offer users full-duplex bandwidth ranges

between 5 Gbps and 320 Gbps.

As switches for 5-20 Gbps platforms,

the PRS 5G and PRS 20G are an ideal

solution for cost-competitive, advanced

services applications, such as

medium-range routers with high-demand

packet processing for network access/

edge aggregation; remote location thin

appliances for firewall, SSL, VPN,

security, intrusion detection; data center

server appliances with deep packet

processing; NAS/SAN equipment; and,

more generally, service applications

requiring a 10-Gbps uplink capability.

As fabric interface devices for line

cards, the PRS 5G and PRS 20G (PRS

C48X and PRS C192X) enable cards

designed for 5-20 Gbps platforms to be

used in chassis-based platforms

addressing the higher-capacity needs of

applications in the Metro/WAN, wireless

infrastructure, and enterprise (data

center, NAS/SAN, High-end LAN). Cards

implementing the PRS C48X or PRS

C192X fabric interface can equip single-

stage switching systems based on PRS

80G, PRS 64Gu, or PRS Q-64G switch

devices, offering up to 320 Gbps of

full-duplex user bandwidth.

The integration of self-switching and

fabric interface capabilities into a single

device provides system vendors with an

easy path to scale their platforms from

smaller-capacity systems up to high-end,

chassis-based solutions capable of

switching up to 320 Gbps of full-duplex

aggregate user traffic, while optimizing

and protecting their line card design

investments. With such OEM offerings,

operators can deploy entry versions of

next-generation, chassis-based

platforms, while they are introducing

Cost Effective Switch Fabric Solu-

tions for Smaller-Capacity Multi-

Service Provisioning Platforms,

Scalable to High-end Systems

The AMCC PRS 5G and PRS 20G

devices are members of the Packet

Routing Switch (PRS) multi-purpose

switch fabric family. They bring greater

granularity and Internet class of service

to smaller-capacity systems such as

remote access devices, enterprise

networking equipment, and low-end SAN

systems. The PRS 5G and PRS 20G

provide a flexible switching solution to

satisfy the demand of applications

offering 5-20 Gbps of full-duplex

aggregate user bandwidth with an

overspeed factor of two.

An integral part of a complete system

solution with AMCC network processors,

traffic managers, framers, and software

tools, the seamless upgrade path of the

PRS 5G and PRS 20G to

higher-capacity solutions, such as the

PRS 80G, enables customers to develop

efficient, smaller-capacity systems today,

and easily evolve to larger systems in

the future.

The PRS 5G and PRS 20G chips are

implemented with IBM 0.13 micron

technology, use IBM 3.2-Gbps

high-speed serial links, and introduce

new system design options, such as PL3

interfaces for network processors and

traffic managers (in addition to CSIX-L1).

Dual Functionality, Switch and

Fabric Interface, for Single Design

of User Cards Across Entire

Product Lines

The PRS 5G and PRS 20G solutions

are hardware and software compatible
