BCM56700
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.
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
