and maintains the routing tables. For a host module to function, both of these
components must be installed and operational.
PICs are available in supported media types, including Asynchronous Transfer Mode
(ATM), Channelized DS3, E1, E3, T1, Ethernet, SONET/SDH, and IP services. The M160
router supports both M160 and M40e PICs. For more information about supported PICs
for each M Series router type, see the appropriate PIC installation guide.
The M160 router Internet Processor II ASIC forwards packets at a throughput rate of up
to 160 Gbps. The ASIC technology provides such packet processing as route lookups,
filtering, sampling, rate limiting, load balancing, buffer management, switching, and
encapsulation and de-encapsulation of IP services.
