Performance Management for Efficient QoS provision and Resource Utilisation in Broadband Internet Infrastructures

An important problem of broadband Internet infrastructures is efficient resource utilisation at access points, while keeping the Quality of Service (QoS) demands of applications stable and optimal. Considering the resource bottleneck of broadband access networks, there is a need for integrated performance management of such networks providing “feedback” from monitoring and analysis of traffic, QoS parameters, topology and anomaly effects for the purpose of short and long term bandwidth resource planning. This paper is aimed to discus design challenges of advanced performance management architecture for efficient bandwidth resource planning of broadband access networks with monitoring “feedback”. Based on resource planning and performance data base, the proposed architecture is designed to include techniques and algorithms for modelling and simulation of optimal resource allocation strategies in advance considering impact of traffic, topology selection, and anomaly analysis as well as feedback from QoS analysis. Application specific QoS monitoring and analysis is used for validation of resource allocation planning considering QoS based applications, such as VoIP, multimedia and Grid. The architecture is derived from the experiences of INTERMON project for inter-domain QoS analysis studying the impact of topology and traffic (see [1], [2], [4]). A scenario for the integration of QoS and topology analysis of INTERMON toolkit in the proposed performance management architecture is described.
