addition, each interface module has a temperature sensor. This design ensures
that high priority packets such as voice over IP packets are forwarded with
minimal delay while lower priority queues are not starved resulting in

With its low profile design, the BigIron RX-16
switch can be stacked three high in a single seven -foot rack providing for as
many as 192 wire-speed 10-GE ports.
"Second generation 10-GE solutions developed in the early 2000's helped
launch 10-GE as a strategic and enabling technology for both enterprises and
service providers," said Bobby Johnson, Chairman and CEO of Foundry Networks.
In addition to module redundancy, the BigIron RX switches support a number
of other design features to maintain continuous operation.

Clos Switch with Adaptive Self-Routing and Virtual Output Queue

distributed packet scheduling.com. The forward -looking
statements in this press release are subject to a number of risks and
uncertainties which could cause actual results to differ materially.sec.com

The BigIron RX switch family incorporates the
latest advancements in switch fabric design, system redundancy and traffic
management to enable the next generation of scalable, secure, and
high-availability networking solutions. To protect against memory corruption, the BigIron
RX management modules use ECC SDRAM to auto-detect and correct memory errors. Each output port supports
eight priority queues providing the granularity and flexibility to support a
range of service classes. Plus, because the MIB is used
to model data, the agent can be accessed using SNMP, CLI, XML, HTTP, and
other protocols without any additional coding.

Foundry Introduces Industry's First Switch Family Scaling to Over One Billion Packets and 1.5 Terabits Per Second

The Clos switch architecture provides very low packet latency
and jitter and allows for future scalability using multi-stage designs.
The VOQ design eliminates head of line blocking that can occur in output
buffered switches. The VOQ design supports as many as 8,000 QoS flows per 10GE
port providing massive scalability for QoS services.

Over the years, SNMP Research developed the "five-step method" for agent
development that employs automatic code generation tools that deploy an
agent with very little hand-coding necessary. We provide innovative solutions for
extensible agent, manager station, and mid-level manager implementations
that are based on SNMPv1, SNMPv2, SNMPv3 , HTTP, XML, and other protocols.

Additionally,
the BigIron RX supports Weighted Random Early Detection (WRED) to gracefully
govern TCP flows in the event of switch congestion. Cut the time it takes
to develop an agent in half.

MIBGuide Browser provides a "test as you go" approach for testing agent
implementations, making an often difficult step much easier.

BigIron RX switch will continue to operate, but at a reduced capacity. If the maximum temperature
threshold is exceeded for a module, it will be disabled by the system to avoid

The BigIron RX-series family includes three chassis models, each
supporting redundant management, redundant switch fabric and redundant power
supply components. The
BigIron RX architecture supports redundant common equipment for all three
chassis models. A module carrier configured
in a full-height slot accommodates two half -height port modules. The BigIron RX is the only switch
family that ships both 40-GE-ready and 100 -GE ready. This scalability provides
network operators with significant investment protection for the future.

768 gigabits per second. The scheduling of packets from the VOQ queues to the
switch fabric is controlled by the output ports ensuring that packets are not
transmitted to fully congested ports. sFlow provides hardware-based
and real-time network traffic monitoring, "always-on" fault and performance
management, capacity planning, security policing, and network traffic
accounting across all switch ports.TURBOLAN or visit

The BigIron RX -4 and RX-8 support 2:1 switch fabric redundancy
and the BigIron RX-16 supports 3:1 switch fabric redundancy. The
BigIron RX is the only switch solution in the industry that can tolerate
multiple fabric module failures in this fashion. The system supports up to
500 BGP peers and one million BGP routes in its software routing information
base (RIB) and 512,000 routes in the port module's hardware forwarding
information base (FIB). For traffic policing, the BigIron RX implements dual-
rate , three color policing for marking packet drop precedence. Since
1988, SNMP Research has both developed standard MIBs and assisted customers
with their own proprietary MIB document development. MIBGuide Editor allows the developer to
