Περίληψη The coexistence of multiple applications which compete for the available resources leads to network congestion. The mechanisms implemented to control the congestion (window flow-control, slow-start algorithm) don't use any knowledge about the characteristics of the activity of the applications, resulting in lack of adaptation of its parameters accurately and on time in case of heavy load. In this case insufficient management of critical network resourses (links, buffers) is observed, leading to degradation of network performance and the unpredictable behaviour of its applications. The present work provides a solution to this problem. The basic goal is the design and implementation of a system that has knowledge about applications activity in the network and controls their flow. The proposed system consists of two entities. The first one is responsible for monitoring all the connections on the bottleneck link and for evaluating quantities that reflect their performance (transfered data, t hroughput). The second one, based on the above information and on the required levels of services provided by the network manager, controls the flow of the connections in order to fullfill the above requirements. The system has been implemented and is used to manage a bottleneck link interconnecting high speed LANs. The system had as a result the traffic to conform to the quality of service requirements and the network utilization to increase. We believe that future network management tools will include such systems in order to improve the quality of service offered by the network to the end user.
