Modern multimedia applications require new services from communication systems. Quality of Service(QoS)[6] is one of the core issues in multimedia systems. QoS is established through negotiation between users and service providers. The negotiation typically involves allocation and management of resources in order to attain a desired level of quality. Unfortunately, in present day systems, the network utilization in terms of the number of requests serviced is far from the optimum. In this paper we propose an efficient network resource management mechanism for dynamically handling the requests over a network. We exhibit a method of rerouting existing connections and accommodating new connections through this route in order to maximize the number of connections serviced and the net data transfer through the network. The algorithm also includes renegotiation of QoS parameters for existing connections with the end system to increase the utilization of the network. Simulation experiments indicate that the network utilization, in terms of number of connections served and the amount of data transferred in the network, increases substantially in comparison to existing procedures.
