This book focuses on the critical challenges facing the future deployment and management of multimedia services over the Internet. It covers a broad scope of issues related to the integrated control and management of multimedia networks and services, and presents practical solutions as well as new research directions in managing QoS in the context of the Multimedia Internet. The following issues are considered, among others: QoS in Internet networks; Managing multimedia networking; Network programmability; Policies and service management; Advanced techniques for network management. This volume is the proceedings of the Third International Working Conference on Management of Multimedia Networks and Services (MMNS'2000), which was sponsored by the International Federation for Information Processing (IFIP) Technical Committee 6 (TC6) and was held in Fortaleza, Ceará, Brazil, in September 2000. MMNS'2000 is co-sponsored by the Communications Society (ComSoc) of the Institute of Electrical and Electronics Engineers (IEEE). Managing QoS in Multimedia Networks and Services is essential reading for engineers, network managers, and designers of multimedia services, as well as for graduate students and researchers in multimedia networking and network management areas.
