    Abstract: The FIT project has addressed a number of problems arising in controlling the traffic and providing quality of service in the Internet and in analyzing the performance of the system. An efficient recursive algorithm has been developed for calculating the flow level performance of elastic traffic under a bandwidth sharing scheme called balanced fairness (BF). The notion of BF has been extended and applied to the flow throughput estimation in ad hoc networks; also other applications of BF are being explored. Scheduling mechanisms, in general, and adaptive scheduling mechanism with delay bounds, in particular, were studied. A simple adaptive and distributed load balancing mechanism has been suggested and analyzed. In this system, traffic is gradually redistributed based on measured link loads, leading to a nearly optimal performance. Analytical results have been obtained on the performance of MAC protocols in ring networks employing optical burst switching. For traffic matrix estimation, the Gravey-Vaton method has been analyzed in detail in the case of Gaussian traffic variations. The stability problem of an overloaded network with measurement-based admission control has been analytically solved.
