Interface Process

The JUNOS interface process (ifd) supplies the programs that configure and
monitor network interfaces by defining physical characteristics such as link
encapsulation, hold times, and keepalive timers.

Forwarding Process

The JUNOS forwarding process (
transmission through a Services Router. The overall performance of the router
is largely determined by the effectiveness of the forwarding process.

User Interfaces

The user interfaces on a Services Router interact with the management process
to execute commands and store and retrieve information from the configuration
database. The user interfaces operate as clients that communicate with the JUNOS
Internet software through an application programming interface (API).
The following primary user interfaces are shipped with the router:
For more information, see "J-series User Interface Overview" on page 109.
Other user interfaces for the Services Router interact with the management
process through the common API interface. These interfaces are designed to
facilitate the configuration of one or, in some cases, many routers on the network.
Among the supported interfaces are the JUNOScope and Service Deployment
System (SDX) applications. For more information about these products, see the
JUNOScope Software User Guide and the SDX Software Basics Guide.
J-Web graphical user interface—Includes quick configuration capabilities for
performing the minimum required steps to enable a feature, plus a built-in
configuration editor with access to the entire configuration hierarchy to fully
configure the router. The J-Web interface also provides tools for monitoring,
managing, and diagnosing router operation.
Command-line interface (CLI)—Grants access to the complete JUNOS
command and configuration hierarchies, to monitor and diagnose the router
and configure it completely.
