Internet Applications Module Documentation

The goal of this module is to hold all the Internet-specific applications, and most notably some very specific applications (e.g., ping) or daemons (e.g., radvd). Other non-Internet-specific applications such as packet generators are contained in other modules.

Model Description

The source code for the new module lives in the directory src/internet-apps.

Each application has its own goals, limitations and scope, which are briefly explained in the following.

V4Ping

This app mimics a “ping” (ICMP Echo) using IPv4. The application allows the following attributes to be set:

• Remote address
• Verbose mode
• Packet size (default 56 bytes)
• Packet interval (default 1 second)

Moreover, the user can access the measured rtt value (as a Traced Source).

Ping6

This app mimics a “ping” (ICMP Echo) using IPv6. The application allows the following attributes to be set:

• Remote address
• Local address (sender address)
• Packet size (default 56 bytes)
• Packet interval (default 1 second)
• Max number of packets to send

Radvd

This app mimics a “RADVD” daemon. I.e., the daemon responsible for IPv6 routers advertisements. All the IPv6 routers should have a RADVD daemon installed.

The configuration of the Radvd application mimics the one of the radvd Linux program.

Examples and use

All the applications are extensively used in the top-level examples directories. The users are encouraged to check the scripts therein to have a clear overview of the various options and usage tricks.
