Synchronization between locations is an important factor for enabling remote shared experiences. Still, experimental data on what is the acceptable synchronization level is scarce. This paper discusses the synchronization requirements for watching online videos together - a popular set of services that recreate the shared experience of watching TV together(More)
In this paper, we describe an SDN-based plastic architecture for 5G networks, designed to fulfill functional and performance requirements of new generation services and devices. The 5G logical architecture is presented in detail, and key procedures for dynamic control plane instantiation, device attachment, and service request and mobility management are(More)
The media possibilities of consumers have exploded over the last two decades, allowing almost everyone today to get a wide range of interactive services and multimedia content via multiple network infrastructures. For example, high-quality professional content with remotecontrol-based interactivity is available through IPTV networks and set-top boxes,(More)
The aim of this paper is to illustrate the architecture for multimedia content management support in new generation service platforms. The outlined architecture is based on the requirements identified by a set of interviews with experts from the media industry. According to the results of the interviews, the architecture has been structured into three main(More)
The development of methodologies to manage and orchestrate virtualised resources and network functions is a fundamental enabler for optimally utilising physical ICT infrastructures. Algorithms for optimal location (embedding) of network functions, IT and CT resources, services and corresponding states, especially at the network edge, will enable new(More)
The concept of CloudNets, virtual networks connecting cloud resources, has recently attracted much interest from both academic as well as business sides. CloudNets can realize the vision of affordable customized infrastructures. In particular, such networks are expected to be offered even in federated environments with multiple providers. Inter-provider(More)
This paper demonstrates the advantages of using structured multimedia documents for session management and media distribution in ubiquitous environments. We show how document manipulations can be used to perform powerful operations such as content to context adaptation and presentation continuity. When consuming media in ubiquitous environments, where the(More)
