New Switch Family Lays Foundation for Next Generation LANs, High Performance
Computing and Metro Networks with Unprecedented Performance , Redundancy, Wire-
Speed Ethernet/IPv4/IPv6, Embedded Security and End-to-End Quality of Service

LAS VEGAS, Foundry Networks(R), Inc.
In addition to module redundancy, the BigIron RX switches support a number
of other design features to maintain continuous operation. The sensor is used
to control the system's fan speed and airflow. The BigIron RX is the only switch
family that ships both 40-GE-ready and 100-GE ready. This control messaging from output to
input enables the system to maintain QoS across the switch fabric.sec.

The BigIron RX-series provides a
flexible , scalable and fully redundant high-performance solution for a wide
range of environments including enterprise backbones, data centers,
high-performance computing and service provider networks. BigIron RX systems can scale to support large environments with
extensive capacities in key areas including the BGP routing information base
(RIB), the number of hardware-switched IP routes, MAC addresses , access
control lists (ACL), traffic policers and more. This design provides for very low latency and wire-speed
performance for all packets in a flow. This scalability provides
network operators with significant investment protection for the future.

Additionally, it provides for routing around backplane failures such as
electrical faults and fair utilization of backplane bandwidth independent of
packet content. Additionally,
the BigIron RX supports Weighted Random Early Detection (WRED) to gracefully
govern TCP flows in the event of switch congestion.

The BigIron RX-4 is a compact four rack unit (RU) high
switch.

Clos Switch with Adaptive Self-Routing and Virtual Output Queue
Architecture Deliver Non-blocking Performance , Low Latency, Fault Tolerance
and Quality of Service
At the heart of the BigIron RX architecture is a single-stage, adaptive
self-routing Clos switch fabric with virtual output queuing (VOQ) and
distributed packet scheduling. Each output port supports
eight priority queues providing the granularity and flexibility to support a
range of service classes. For
network monitoring, the BigIron RX switches support the industry-standard
sFlow(TM) packet sampling described in RFC 3176. In
addition , hardware features, cost, power consumption, and board space
have been carefully optimized for maximum suitability in access
environments. In addition, flexible stacked VLAN tag mapping,
manipulation , and modification capabilities support a variety of
network topologies, including VPNs/VPLS and hardware platform sharing
by multiple service providers. These

Redundant and Resilient Design
To ensure business continuity in the event of equipment failures, the
BigIron RX switches are designed with no single point of system failure. To protect against memory corruption, the BigIron
RX management modules use ECC SDRAM to auto-detect and correct memory errors. The switch fabric in all
three models delivers 96 Gbps full-duplex, non-blocking capacity per
full-width module slot and 48 Gbps per half-slot. The
switch's adaptive self-routing capability provides for a more scalable
solution than architectures that rely on centralized packet schedulers .1x, RADIUS, and TACACS+.

Even in the event of multiple fabric module failures, the
BigIron RX switch will continue to operate, but at a reduced capacity. The
BigIron RX is the only switch solution in the industry that can tolerate
multiple fabric module failures in this fashion.

Unmatched Scalability and Bandwidth Density
The BigIron RX-series switch family is the densest Ethernet switching
solution in the industry, capable of delivering 110 Gbps throughput per rack
unit. 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 . For traffic policing, the BigIron RX implements dual-
rate, three color policing for marking packet drop precedence.
