BCM5615 Broadcom, BCM5615 Datasheet - Page 2

• Manufacturer Part Number: BCM5615
• Description: Integrated Multi Layer Switch
• Manufacturer: Broadcom

The BCM5615, with a forwarding rate of 6.6 Mpps, defines the
next generation of performance for single-chip switching
solutions. Through its advanced ContentAware™ feature set,
the StrataSwitch II
applications and services, at wire speed, with nonblocking
performance.
The BCM5615 uses 60 million transistors with 1 MB of internal
memory to integrate the functionality of large board designs into
a single chip. This level of integration allows the BCM5615 to
sustain line rate on all 24 Fast Ethernet and 2-Gigabit Ethernet
ports for Layer 2, and Layer 3 switching 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 in a
stacking link mode, giving you tremendous scalability for
configuring your switching system.
The BCM5615 also provides a wide range of choices in levels of
manageability and solution costs. For example, the BCM5615
provides a low-cost I
well as a 33/50-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.
