Software Overview
Each J-series Services Router runs the JUNOS Internet software on its
general-purpose processors. Designed for the large production networks typically
supported by Internet service providers (ISPs), the JUNOS software includes
processes for Internet Protocol (IP) routing and for managing interfaces, networks,
and the router chassis.
The JUNOS Internet software runs on the Routing Engine. The Routing Engine
kernel coordinates communication among the JUNOS software processes and
provides a link to the Packet Forwarding Engine.
With the J-Web interface and the command-line interface (CLI) to the JUNOS
software, you configure the routing protocols that run on the Services Router and set
the properties of its network interfaces. After activating a software configuration,
use either user interface to monitor the protocol traffic passing through the router,
manage operations, and diagnose protocol and network connectivity problems.
