Data Sheet
MUAA Routing CoProcessor (RCP) Family
APPLICATION BENEFITS
•
High performance MAC Address processor for
multiport switches and routers (Up to 48 10/100 or 4
Gigabit Ethernet at wire speed)
Layer 4 flow recognition for Quality of Service up to
16.7 million packets per second
ARP Cache manager/IP address caching at 12.5
million packets per second
Synchronous interfaces and programmable priority
between ports for simplicity of design
Learn, age, and auto-age functions with “virtual
queues,” keeping track of aged and learned entries
Transparent cascade of up to four 2K devices without
external logic, software setup, or performance hit
