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 OS to handle routing protocols, traffic engineering, policy, policing, monitoring, and
configuration management. Forwarding operations in the router are performed by the
Packet Forwarding Engine.
