extend the system capacity. This is
possible because the PRS 5G
alternately operates as a PRS C48X
switch fabric interface providing queuing
manager functionality for PRS core
switches. As a result, the same PRS 5G
blades can be used in both meshed and
centralized switch fabric topologies, thus
optimizing OEM and user investments in
PRS 5G-based blades.

PRS 5G Switch Fabric for 5-20
Gbps Meshed Switch Systems (No
Central Switch Fabric)
The PRS 5G (PRS C48X) switch fabric
device provides 2.5 Gbps of full-duplex
minimum aggregate user bandwidth. It
allows smooth growth of
smaller-capacity systems by the simple
addition of PRS 5G-based blades,
without any central switch fabric. Eight
PRS 5G devices can be linked together
in a meshed topology to enable the
design of systems with up to eight user
blades, each with a PRS 5G device
attaching a network processor such as
the AMCC nP3700 Integrated Network
Processor / Traffic Manager (see
Figure 1
and
Figure 2
).
More compact blades, housing
multiple network processors, can be
implemented with PRS 20G devices.
The PRS 20G can also operate in a
meshed configuration with the PRS 5G
to provide 10-Gbps uplink capability in
smaller-capacity systems (see
Figure 3
).
The PRS 5G blades can be designed
to preserve the possibility of adding a
central PRS switch, when needed to
A standard-based AdvancedTCA
TM
chassis can be used in the design of
PRS systems that can evolve from a few
tens of Gbps to 100 or 120 Gbps of
full-duplex user bandwidth.
