The BCM5646, with a forwarding rate of 8.9 Mpps, defines the next
generation of performance for 48-port Fast Ethernet switching solutions.
Through its advanced ContentAware™ feature set, the StrataSwitch II™
product family supports advanced applications and services, at wire
speed, with non-blocking performance.
The BCM5646 uses 60 million transistors and 1 MB of internal memory
to integrate the functionality of large 48-port board designs into two
chips. This level of integration allows the BCM5646-based switch to
sustain line rate on all 48 Fast Ethernet and 2-Gigabit Ethernet ports for
Layer 2 and all L2-L7 processing applications.
The StrataSwitch II™ Fast Filter Processor (FFP) delivers line rate
packet processing to support policy management, VoIP, and firewall
applications.
The data packet memory can be extended from 4 MB to 64 MB using
commodity SDRAM in either a 128-bit-wide interface or a 64-bit-wide
interface.

The StrataSwitch™ family supports using the gigabit ports or
TurboGig™ in a stacking link mode, giving you tremendous scalability
configuring your switching system.
The BCM5646 also provides a wide range of choices in levels of
manageability and solution costs. For example, the BCM5646 provides
a low-cost I2C interface for unmanaged applications, as well as a 33-
MHz PCI interface for higher management and network service
requirements.
The flow metering and monitoring of the StrataSwitch II™ enables many
new applications and services. ISPs can benefit from the metering
capabilities of the StrataSwitch II™, eliminating unregulated bandwidth
from over-consuming their network. Using the monitoring features of
the FFP, IT managers can gain tremendous insight to the utilization of
their current network resources and optimize those resources
accordingly.
