  • Context-aware distributed multimedia provisioning based on anycast model towards Future Media Internet
    2011
    Co-Authors: Soraya Ait Chellouche, Daniel Négru, Eugen Borcoci, Eric Lebars
    Abstract:

    The Future Internet is foreseen to fully handle multimedia services which have experienced an explosive growth in the recent years. Therefore, improving the scalability of these services is getting crucial. One common approach for this purpose is the deployment of multiple replicas of a server throughout the network. The resulting issue is to direct the user request to the best server. Methods based on application - layer anycast service constitute good means to (1) support the server's replication strategy and (2) process an appropriate server selection algorithm for the client request according to different metrics. This paper presents an efficient context-aware anycast multimedia provisioning scheme. In addition to the clients and servers nodes, the adopted architecture involves enhanced Service Registry (SR) nodes, in a distributed mode. SRs have two main roles: first, they collect and maintain the servers' contexts and their content description; second, they perform the mapping of the anycast address of the client request to the unicast address of the most convenient server based on both the client and servers contexts, including the underlying network conditions. The paper presents the evaluation of the proposed video provisioning scheme through intensive simulations. The promising results led to the launch of real developments to be undertaken in the framework of a large-scale European project ALICANTE which objective focuses on Future Media Internet.

  • Dynamic class-based queue management for scalable media servers
    Journal of Systems and Software, 2003
    Co-Authors: Aaron Striegel, G. Manimaran
    Abstract:

    Real-time media servers are becoming increasingly important due to the rapid transition of the Internet from text- and graphics-based applications to multimedia-driven environments. In order to meet these ever increasing demands, real-time media servers are responsible for supporting a large number of clients with a heterogeneous mix of quality of service (QoS) requirements. In this paper, we propose a dynamic class-based queue management scheme that effectively captures the trade-off between scalability and QoS granularity in a media server. We examine the adaptiveness of the scheme and its integration with the existing schedulers. Finally, we evaluate the effectiveness of the proposed scheme through extensive simulation studies.

  • Optimization of Multi-server Video Content Streaming in 5G Environment
    2016
    Co-Authors: Eugen Borcoci, Tudor Ambarus, Joachim Bruneau-queyreix, Daniel Négru, Jordi Mongay Batalla
    Abstract:

    This paper presents a preliminary work, proposing an architectural control plane solution for optimization of multiple-server video content streaming in 5G wireless environment. The starting point was an existing video streaming delivery system, having a light, over-the-top (OTT) architecture, which performs for each client request of a content object, an initial selection among multiple servers and paths, then followed by in-session dynamic media adaptation. This work extends the above system concepts to a different environment, i.e., heterogeneous Cloud Radio Access Network and cooperation with Mobile Edge Computing. The proposed solution can support recently developed multi-server and multi-path dynamic adaptive streaming over HTTP.
