PRS 20G Switch Fabric for
10 Gbps (Single-card) or 20 Gbps
(Two-cards) Smaller-Capacity
Systems
The PRS 20G (PRS C192X) switch
fabric device enables the implementation
of one-card or two-card systems
providing 10-20 Gbps of full-duplex
minimum aggregate user bandwidth.
A single device operates as a 10-Gbps
full-duplex switch fabric providing 4x4
switch ports at 2.5-Gbps/OC-48c speed,
with a standard CSIX-L1 or PL3 interface
to network processors such as the
AMCC nP3700 Integrated Network
Processor / Traffic Manager (see
Figure 4).
In a two-card system, the two PRS
20G devices can operate as an 8x8 port
switch fabric, with each port supporting
2.5-Gbps/OC-48c speeds, thus offering
an aggregate full-duplex throughput of
20 Gbps. As another two-card
configuration, one of the PRS 20G
devices can be configured with a single
10-Gbps/OC-192c port with a standard
CSIX interface to a network processor,
so as to provide the uplink aggregating
the traffic of the four 2.5-Gbps/OC-48c
ports of the other card (see Figure 5).
