used for network debugging and analysis. It can connect to a remote system on a specified port,

D-ITG: Dynamic Internet Traffic Generator
The D-ITG program that generates data packets to simulate network traffic. It is able to create
data packets using the ICMP, UDP and TCP protocols. The size of the packets, interval between
the packets, length of test, and packet rate can also be controlled. These parameters can either be
given a constant value, or specified to follow a random distribution. At the end of each simulation
a numerical summary of the data flow is provided. [6]
