[edit] Definition of Fairness in communications networks

Fairness is also a concept used in telecommunications networks. It describes the service discipline to be used by networks routers in presence of a congestion phenomenon. This means that fairness is a criterion used to distribute the available network resources among competing flows.

The most common fairness criterion is called Max-min fairness. An intuitive description of this criterion is that flows restricted at the same bottleneck link are entitled to the same amount of resources.

Additional fairness criteria are: weighted max-min and proportional fairness, for example.
