CbrSender

simple module

Simple module for generating Constant Bit Rate (CBR) traffic. This module periodically sends packets of a specified size to a designated address and port. The intervals between packets and the overall duration of the communication are configurable. The module emits statistics related to the generated throughput and the total amount of bytes sent.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.
