Delivering desired QoS to the applications is one of the most important challenges in next generation networks. Designing efficient queue management in midway nodes leads to improvement in NGN efficiency. This paper presents fair Efficient active Queue Management (EQM) mechanism for congestion avoidance and control in next generation networks. Proposed AQM mechanism uses instantaneous queue length...
Work on the development of end-to-end QoS control management architecture for Next Generation Networks started at ITU-T a few years ago and it is still under way. This paper provides an overview of some of the protocols proposed by ITU-T (COPS-PR), describes others (COPS-SLS) developed to cover functionalities which have no corresponding protocols to date. This paper details the development of a mechanism...
Frequency is amongst the most exclusive and most costly resources in wireless communication networks, especially, while considering the demands of broadband wireless access (BWA). In BWA, the management of frequency distribution and its effective utilization is of utmost importance. This research explores possible ways to ensure the most effective allocation of bandwidth resources and their best possible...
Resource and admission control function (RACF) is the main part of resource management architecture in next generation networks (NGN). In this paper we analyze the effect of different resource control schemes in RACF architecture on some network performance parameters and show that a dynamic policy for scheme selection will outperform the static one. The dynamic policy results in better resource utilization...
