Multiparty cloud video conferencing architecture has been recently advocated to exploit rich computing and bandwidth resources in the cloud to effectively improve video conferencing performance. As a typical design in this architecture, multiple agents, i.e., virtual machines, are deployed in different cloud sites, and users are assigned to the agents. Then, the users communicate through the agents,...
Ground personnel at the tactical edge often lack data and analytics that would increase their effectiveness. To address this problem, this work investigates methods to deploy cloud computing capabilities in tactical environments. Our approach is to identify representative applications and to design a system that spans the software/hardware stack to support such applications while optimizing the use...
The evolution of Cloud Computing beyond the frontier of a single datacenter is justified as a mean to enhance various system architecture aspects like: cost, geo-locality, energy efficiency and structural properties. Orchestration of different cloud providers in order to ensure better Quality of Service (QoS) is refered to as Multi-Cloud. One such multi-cloud federation model is Community Clouds,...
Wireless data traffic, especially video traffic, has been growing at a rapid pace. Innovative network architectures and protocols are needed to improve the efficiency of data delivery. The trend toward integrating advanced information technologies and communications technologies is creating unprecedented opportunities in the design of infrastructure for network-centric services. The rapid growth in...
This paper introduces GENI Cinema (GC), a system that provides a scalable live video streaming service based on dynamic traffic steering with software defined networking (SDN) and demand driven instantiation of video relay servers in NSF GENI's distributed cloud environments. While the service can be used to relay a multitude of video content, its initial objective is to support live video streaming...
Mobile cloud computing is emerging as a new paradigm for supporting a broad range of multimedia services. MCC alleviates the burden of storage and computation on mobile devices. In this article, we describe design requirements and an architecture for MCC. The novelty in this architecture is an integrated cloudlet and base station subsystem that can meet application-level quality of service requirements...
