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
with the PRS 80G, PRS 64Gu, and
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
