Revision P4
1.2.1 Configuration and Control
The IDU includes a number of features that make it easy to configure and control all
aspects of its operation. These include:
• Monitoring the status of the IDU (see
section 2.1
).
• Controlling the IDU's access to the satellite network (see
section 2.2
).
• Configuring quality of service to determine how the IDU queues and transmits data
over the satellite network (see
section 2.4
).
• Configuring the IDU's IP addresses for the satellite network and the LAN (see
section
2.3
).
• Sending and receiving files, including software upgrades, configuration files, IPSec
keys, event log files and customized logos for the web page interface (see
section
2.6
).
In addition, the IDU web interface supports a number of advanced configuration and con-
trol features. See sections
3.1
to
3.3
.
1.2.2 Security and Passwords
The IDU incorporates a variety of security features to protect the integrity of the SIT, the
satellite network and the data sent over the satellite links.
Access to the IDU web interface is encrypted and secure (see
section 4.1
). In addition,
access requires a password (see
section 4.4
).
The IDU supports two security protocols that may be implemented in the satellite net-
work.
• RADIUS requires the SIT to authenticate a username and password with a RADIUS
server at the hub before it can send data over the satellite network (see
section 4.3
).
• Internet Protocol Security (IPSec) requires data sent over the satellite network to be
encrypted and secure (see
section 4.2
).
Note: The procedures described in this document assume familiarity with
satellite networks, satellite network equipment installation, and the DVB-
RCS standard.
1.3
Introduction to DVB-RCS and Satellite Interactive Terminals (SITs)
This section provides an overview of DVB-RCS and satellite interactive terminals (SITs).
1.3.1 Digital Video Broadcast-Return Channel System (DVB-RCS)
DVB-RCS is an open standard for providing two-way broadband access over satellite.
• The forward link carries communication from a gateway, via satellite, to satellite
interactive terminals (SITs) and is based on the DVB/MPEG standard. Forward link
communication is normally in the Ku band.
