Abstract:
An important problem of broadband Internet infrastructures is effi-cient 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 per-formance 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 broad-band 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 al-location strategies in advance considering impact of traffic, topology selection, and anomaly analysis a
s well as feedback from QoS analysis. Application specific QoS monitoring and analysis is used for validation of re-source 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 to-pology and traffic (see [1], [2], [4]). A scenario for the integration of QoS and topology analysis of INTERMON toolkit in the proposed performance man-agement architecture is described.
