Queueing Tutorial

INET contains a queueing library which provides various components such as traffic generators, queues, and traffic conditioners. Elements of the library can be used to assemble queueing functionality that can be used at layer 2 and layer 3 of the protocol stack. With extra elements, the queueing library can also be used to define custom application behavior without C++ programming.

Each step in this tutorial demonstrates one of the available queueing elements, with a few more complex examples at the end. Note that most of the available elements are demonstrated here, but not all (for example, elements specific to DiffServ are omitted from here). See the INET Reference for the complete list of elements.
