چکیده
We study the role of pricing in Diierentiated Services (DiiServ) networks. We model DiiServ as a priority service, where users are given the freedom to choose the priorities of their traac, but are charged accordingly. Using a game theoretic framework, we study the case where users choose an allocation of priorities to packets in order to optimize their net beneet. For the single link case, we show that there always exists an equilibrium for the corresponding non-cooperative game, which, however, is not necessarily unique. Furthermore, we show that in equilibrium, packet loss depends only on pricing decisions. This suggests that pricing can be used as a tool to control link congestion.
