and IP switching where throughput is of
prime importance. The multistage
method is ideal for applications that
require extensive connectivity and
experience low average traffic.
Link paralleling supports
OC-192c port speed
By grouping four physical ports to form a
unique logical port, the powerful link
paralleling feature can support a range
of high-speed port requirements
Manufacturers using this capability can
migrate easily from OC-48c to OC-192c
port speed and mix OC-48c and
OC-192c port speeds on the same
switch, while protecting their hardware
and software investment. For example,
four PRS64G ports (OC-48c-capable)
can be bundled to form a unique
OC-192c clear port.
The chip also features shared memory
space among its ports to enable
enhanced performance, and its Grant
method-based flow control allows the
traffic manager to perform virtual output
queuing. The chip also provides four
levels of traffic priority, enabling applica-
tions to give precedence to, for example,
real-time traffic such as voice and video.
Redundancy support for
high availability
To increase availability, switch fabrics are
often designed with two redundant
planes. If an element in one plane fails,
the other plane is can take over; the
PRS64G supports this crucial capability.
Each switch element has a built-in
filtering mechanism for redundancy
control. The dual links from the switch-
element access manager to the switch
core provide the means for lossless
switchover.

Highly efficient multicast
support
Multicast with QoS is an increasingly
valued capability in Internet applications.
The PRS64G supports efficient multi-
casting, simplifying the design of edge
routers and other devices that provide
these complex services. To enable
multicasting and maximize product
resource utilization, the PRS64G executes
a scheme of share once and transmit
multiple times. The packets are placed in
shared memory and the memory-
location indexes are stored in the output
queues corresponding to the target
output ports and associated priorities.
Serial interface chip available
To simplify the design of chassis-based
systems requiring a high-speed intercon-
nect across a backplane or short cable
distances, IBM offers the IBM packet
routing switch serial interface. This
companion chip converts a data-aligned
serial-link interface to a Utopia 3-like
parallel interface. This chip allows traffic
managers supporting 32-bit parallel
interfaces to connect to redundant switch
fabrics that are built on the PRS64G.
Enablement tools support
expedited time to market
IBM offers packet-switch controller
software and a reference switch core to
help reduce development time and cost.
The software offerings, which include
the IBM primary switch controller (PSC)
software and IBM secondary switch
controller (SSC) software, operate the
switch subsystem control layer. The
128-Gbps reference-switch core is well
suited for a redundant 32-port OC-48c
ATM switch or a layer-2 and above
design that supports 32- to 128-port
Gigabit Ethernet.
