On utility-optimised router-level bandwidth allocation
Kelly’s network utility maximisation (NUM) problems and solutions are aimed to maximise the aggregate utility subject to link capacity constraints. They are formulated and solved by using the individual flow rate vector. Because of the architecture of the current networks such as the Internet, the individual flow rates are generally not measurable directly at the routers for the network service...
متن کاملUtility based fair bandwidth allocation
For over a decade, the Nash Bargaining Solution (NBS) concept from cooperative game theory has been used in networks as a concept that allows sharing resources fairly. Due to its many appealing properties, it has recently been used for assigning bandwidth in a general topology network between applications that have linear utilities. In this paper, we use this concept for the bandwidth allocatio...
متن کاملUtility-oriented adaptive QoS and bandwidth allocation in wireless networks
In this paper we propose a general utility-oriented adaptive Quality of Service (QoS) model for wireless networks and establish a framework for formulating the bandwidth allocation problem for users with timevarying links. For slow link variations, it is inadequate to only employ lowlevel adaptive mechanisms at the symbol or packet level, such as error correction coding or swapping packet trans...
متن کاملUtility Proportional Fair Bandwidth Allocation: An Optimization Oriented Approach
In this paper, we present a novel approach to the congestion control and resource allocation problem of elastic and real-time traffic in telecommunication networks. With the concept of utility functions, where each source uses a utility function to evaluate the benefit from achieving a transmission rate, we interpret the resource allocation problem as a global optimization problem. The solution...
متن کاملUtility Max-Min: An Application-Oriented Bandwidth Allocation Scheme
In this paper, we consider the use of an application-layer performance measure — the utility — in the context of bandwidth allocation for an available bit rate service. Our bandwidth allocation scheme can be viewed as a generalization of traditional available bit rate service; our scheme is equivalent to bandwidth max-min allocation when the utility of all applications are equal. The goal of ou...
