Managing Service Level Quality

Beschreibung

QoS (Quality of Service) and Network Management are old topics.However, the fusion of IP style multimedia and wireless networks(3G) means that network managers who might previously have dealtwith one or the other, must now manage and provide serviceguarantees for the both. This is where Managing Service LevelQuality across Wireless and Fixed Networks steps in... It begins by examining the mechanisms that already existed in fixedIP data networks prior to the introduction of probe and agenttechnology. A look at these later developments is then supplementedwith a real-world scenario of how real time application performancemonitoring can not only provide service level management but canalso aid in root cause analysis. This same model is then applied to a wireless environment examiningwhich elements are required to be able to deliver multimediaservices across 2nd and 3rd generation mobile networks, detailingthe components of data networking that will assist in guaranteeingservice level performance and the constraints placed on thoseguarantees when passing services over an air interface to awireless-enabled device. It asks a simple question: will multimedia applications and theguaranteed levels of service required by them work when traversingfrom fixed to wireless networks? It tracks QoS components and mechanisms of both environments andlooks at what will provide the glue in this brave new convergedworld and also provides empirical data to back up the conclusionsdrawn. * First book available which applies QoS techniques andtechnologies to wireless/mobile networks 3G/UMTS * Deals with the search for the real time information thatconstitutes the "customer experience" in terms of applicationperformance so that service levels can be verified againstmeasurable and relevant data in a true end-to-end manner acrossboth fixed and wireless networks * Presents probe and agent technology * Features a real-world scenario of how real time applicationperformance monitoring can not only provide service levelmanagement but can also aid in root cause analysis - this will beof particular interest to practitioner * Analyses which elements are required in order to delivermultimedia services across 2nd and 3rd generation mobilenetworks * Details the components of data networking that will assist inguaranteeing service level performance Essential reading for Wireless and IP data networkprofessionals/practitioners, network managers and architects,technical consultants, quality assessment engineers, infrastructurevendors, application developers, portal designers, wirelineoperators, lecturers, postgraduates, senior undergraduate studentsand industry trainees.
