# Txc6 Class Reference

Inheritance diagram for Txc6:

List of all members.

## Detailed Description

In this step we'll introduce random numbers. We change the delay from 1s to a random value which can be set from the NED file or from omnetpp.ini. In addition, we'll "lose" (delete) the packet with a small probability.
