Analytical Comparison of Fairness Principles for Resource Sharing in Packet-Based Communication Networks

Current Internet users are enormously increased and application that they are using is magnificently bandwidth devoured. With this manner, Internet is no longer a fair and protective environment. The diversity in the Internet applications required a reconsideration of the mechanisms used to deliver each packet pass through a router in order to provide better fairness and more protective place. Furthermore, the observer of the Internet packet could easily identify the purpose of the delay which is indeed caused by the queuing in the output buffer of the router. Therefore, to reduce such delay for those sensitive applications such as real-time applications, scholars develop many fairness principle which by turn could improve the QoS and hence the fairness and the protection aspect. This study highlight most famous fairness principles used in the literature and some other novel ideas in the concept of fairness. The analytical comparison of these principles shows the weakness and the strength of each principle. Furthermore, it illuminates which fairness principle is more appropriate in which environment.
