BCM5345
Enables a new generation of lower-cost switches with Gigabit
Ethernet connectivity and much smaller form factors.
Complete switch on a chip integrates multilayer forwarding
and filtering logic and internal ARL tables and packet
buffering.
Filters and forwards traffic at full wirespeed on all 25 ports at
all layers of functionality. This equates to 50 Gbps of
bandwidth.
Provides the most cost-effective Gigabit Ethernet connectivity
to the desktop for all remote and branch office as well as
enterprise workgroup needs.
Supports 8K internal MAC addresses, so even large,
segmented networks can be supported.
Supports Quality of Service (QoS) for prioritization of
different traffic types.
Full support of VLANs allows separation of user groups and
minimizes superfluous traffic.
Jumbo frame support allows the device to be connected to
corporate server farms and networks while maintaining
maximum TCP/IP performance.
Supports the latest standards used in corporate networks for
discovery, management, access control, and traffic control.
On-chip MIB registers allow the collection and transmission of
statistics for each port and allow an upward migration path for
corporate users.
