Multimedia Content Distribution over Next-Generation Heterogeneous Networks Featuring a Service Architecture of Sliced Resources

Abstract : Recent advancements of IP networks pave the way for Over-the-Top (OTT) applications. Evolved telecom platforms provide revenue potentials via Service Gateways (APIs) on top of VoIP/RCS (IMS), Machine Type Communication (MTC) and Smart Bit pipe approaches. QoS is achieved through over-provisioning in today’s access and core networks since there are no flexible mechanisms that are available for end-users to influence the QoS level. Processes for user-demanded and operator-controlled QoS management as well as mechanisms for applications signaling their requirements on the data path into the network are far from being adequate. Novel approaches regarding end-to-end inter-domain flow-control architectures, i.e. network slicing, as well as machine-to-machine (M2M) virtualization platforms that handle such functions as device/communication management, session management and bearer and charging management are emerging promising enhanced multimedia communications and efficient utilization of network resources. They promote cloud services and they integrate the computer word into next generation telecommunications.
