The M10i Multiservice Edge Router provides high-speed interfaces for medium and large
networks and network applications, such as those supported by Internet service providers
(ISPs). Application-specific integrated circuits (ASICs), a definitive part of the router
design, enable the router to forward data at the high speeds demanded by current network
media.
The M10i router supports up to eight Physical Interface Cards (PICs). The router height
of 34.80 in. (88.4 cm) enables stacked installation of five M10i routers in a single
floor-to-ceiling rack, for increased port density per unit of floor space.
The router's maximum aggregate throughput is 12.8 gigabits per second (Gbps) simplex
or 6.4 Gbps full duplex. Inserting a combination of PICs with an aggregate higher than
the maximum throughput per FPC is supported, but constitutes oversubscription of the
FPC.
The router architecture cleanly separates control operations from packet forwarding
operations, which helps to eliminate processing and traffic bottlenecks. 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,
which consists of hardware, including ASICs, designed by Juniper Networks.
