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.)
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.
The M10i router provides a maximum aggregate throughput of 12.8 gigabits per second (Gbps). Control operations in the router are performed by the Routing Engine, which runs JUNOS software to handle routing protocols, traffic engineering, policy, policing, monitoring, and configuration management. Forwarding operations in the router are performed by the Packet Forwarding Engine.
