BCM5615 Applic ation Diagram
New service offerings for ISPs.
Pay for bandwidth consumption.
Voice over IP.
Police over-consumption of network resources.
Line rate switching on all ports.
Greater insight to network resource utilization
through the advanced FFP features.
More efficient deployment of existing network
resources through insight provided by
StrataSwitch II
TM
feature set.
Line rate switching on all ports for:
Layer 2 switching.
Layer 3 switching.
All FFP actions — steering, forwarding, reclassifying.
Low power of device, 5W (<250 mW/ FE port),
enables low-cost power supplies.
High level of integration minimizes PCB layer count
and routing issues.
Flexible (128 or 64 bit) SDRAM interface supports low
system cost of memory.
