Abstract

This paper studies about network resource allocation between users that manage multiple connections possibly through different routes where each connection is subject to congestion control I formulate a user –centric Network Utility Maximization problem that takes into account the aggregate rate a user obtains from all connections. In a first proposal a new paradigm for resource allocation in networks which intends to bridge the gap between classical Network Utility Maximization applying to congestion control and the user-centric perspective for fairness. The number of connections can be used to achieve this fairness and I also take one option that is either co-operative control or else through network admission control. By using the term NUM I can able to applied to resources allocation across number of protocol layers. The problem of uncontrolled flow rate is controlled through aggregate rate of connections .By using admission control it ensures both network stability and user centric fairness.
