Abstract: In this paper, we present an innovative distributed quality of service routing scheme suitable to operate in networks of general topology implementing a Diff-Serv service model for QoS support. The proposed scheme is based on a game theoretic non-cooperative model which exploits, on the one hand, the topological information distributed within the network by the current (non-QoS) link-state and distance-vector routing protocols and, on the other hand, the QoS information locally available at the node where the forwarding process takes place. In order to guarantee the satisfaction of a stability condition at each node, a distributed admission control (DAC) scheme is proposed to jointly operate with the non-cooperative routing scheme. The DAC decides if a new flow can be accepted without violating the nodes' stability constraints and provides each node with cumulative information about the status of the network downstream from its outgoing links.
