16-PORT, 192-GBPS LOSSLESS SWITCH FABRIC
FEATURES
SUMMARY OF BENEFITS
• Sixteen 12+ Gbps HiGig2™ or HiGig+™ switch fabric ports
• Non-blocking 192-Gbps wirespeed fabric performance
• Forwarding rate of 240 million packets per second
• Scalable to 1.28 terabit switch in multistage configuration
• Sixteen integrated high-speed XAUI™ interfaces
• Eight priority queues per port for user data
• Dedicated queues for system management packets and flow
control messages allow user data to have eight levels of priority.
• Supports deficit round-robin, weighted round-robin, and
strict-priority scheduling algorithms
• Service-aware flow control guarantees packet delivery.
• Port trunking and mirroring across multiple devices
• Hardware-based mechanism to minimize packet loss in case of
link failure
• Hot-swap capable with AC coupling
• Resilient link configuration through active multipath
forwarding
• Configuration and management via PCI interface
• Advanced diagnostic features including IEEE 1149.1 boundary
scan, JTAG, and extensive BIST functionality
• System vendors can build 160G to 1.28T high-performance,
high-port density chassis systems.
• Integrated data-buffer memory eliminates the need for
expensive, high-speed external memory.
• Multiple classes of service (CoS) and very low latency enable
the support of VoIP and other voice, video, and data
applications.
• Dedicated queue improves flow control response time and
ensures reliable traffic delivery.
• System management queue reduces chassis system cost by
eliminating the need for a separate management network.
• Built-in high-speed serial interfaces with Broadcom-unique
SerDes technology eases and accelerates system design, while
reducing cost and conserving board space.
• Hardware-based failover minimizes packet loss if a link failure
occurs.
• High level of integration and low power enable next-generation
modular and stackable switch solutions.
APPLICATIONS
• Switch fabric in high-performance chassis systems
• Switch fabric in high-end stand-alone or stackable Gigabit-
and 10-Gigabit Ethernet switches
• HiGig™ switch fabric in advanced TCA chassis platforms
