M10i Internet Router Overview
The M10i Internet router provides high-speed interfaces for medium and large
networks and network applications, such as those supported by Internet service
providers (ISPs). (See Figure 3.)
Figure 3: M10i Router
The M10i router includes the router-specific Compact Forwarding Engine Board
(CFEB) which performs route lookup, filtering, and switching on incoming data
packets, then directs outbound packets to the appropriate Flexible PIC Concentrator
(FPC) for transmission to the network. It can process 16 million packets per second
(Mpps).
A High-Availability Chassis Manager (HCM) works with its companion Routing
Engine to provide control and monitoring functions for router components. The
HCM also displays alarm status and takes Physical Interface Cards (PICs) online and
offline.
On the M10i router, built-in FPCs house the PICs that connect the router to network
media. The router supports up to eight PICs, including ATM, Channelized, Gigabit
Ethernet, IP Services, and SONET/SDH interfaces. For more information on PICs,
see the M10i Internet Router PIC Guide.
Some PICs, such as Gigabit Ethernet PICs, accept small form-factor pluggable
tranceivers (SFPs), which are fiber-optic transceivers that can be removed from the
PIC.
