PRS 16G/C192
Switch Fabric
Redundancy Support for High
Availability – PRS C192 Function
To increase availability and meet
service providers’ needs and
high-demanding applications (24x7),
switch fabrics are often designed with
two redundant planes. If an element in
one plane fails, the other plane can
take over. The PRS C192 device
supports this crucial capability, in
conjunction with the PRS 64Gu or
PRS Q-64G switch core devices. Each
switch element has a built-in filtering
mechanism for redundancy control.
On the line adapter, the PRS C192
chip provides a redundant path with
the switch planes, enabling traffic load
sharing and switchover between the
two switch planes, including
maintenance switchover without
packet loss.
enable multicasting and maximize
product resources utilization, the
switch executes a scheme of store
once and transmit multiple times
(replication at sending). The multicast
packet is placed in shared memory
and the memory-location index is
stored in the output queues
corresponding to the target output
ports and associated priorities. When
used as a standalone switch, the
PRS 16G/C192 inherits this leading
multicast architecture, and so helps
customers to efficiently take
advantages of these multicast
applications.
Fabric Interface for
Highly-Scalable Systems –
PRS C192 Functions
The PRS 16G/C192 switch fabric
device is designed to alternately
operate as a PRS C192 switch fabric
interface chip. Located on each
adapter card, it supports either a 10G/
OC-192c network processor or up to
four 2.5G/OC-48c network processors.
It performs the queuing manager
function of a PRS-based switch that
can scale from 4 to 32x10-Gbps/
OC-192c switch ports, or 16 to
128x2.5-Gbps/OC-48c switch ports,
offering up to 320 Gbps of full-duplex
aggregate user bandwidth.
PRS 64Gu and PRS Q-64G switch
core devices use 2.5-Gbps high-speed
serial links for communication with
adapter cards equipped with the
PRS C192 fabric interface chip. The
PRS 16G/C192 provides one 64- or
128-bit wide CSIX-L1 compliant
interface or four 32-bit wide CSIX-L1
compliant interfaces to Network
Processors or Traffic Managers.
Highly Efficient Multicast –
PRS 16G and PRS C192 Function
Multicast with QoS is an increasingly
valued capability in Internet and new
service applications. The PRS 64Gu
and PRS Q-64G switch core devices,
in conjunction with the PRS 16G/C192
device provide a built-in efficient
multicast function, easing the design of
edge routers and other devices that
provide these complex services. To
Enablement Tools for an
Expedited Time to Market
To help reduce development time and
cost, AMCC offers PRS 16G/C192,
PRS 64Gu, and PRS Q-64G switch
evaluation platforms, switch core
reference designs, and reference
software to operate the switch
subsystem control layer. To allow
system vendors to evaluate full
solutions, the PRS platforms are
enabled for attachment of other
suppliers’ NPU platforms. Board
design services and board
manufacturing capabilities
complement the AMCC PRS offering.
