Advancing Multimedia Distribution with SDN/NFV-based Systems

Submission deadline: September 1, 2016
Publication: July-September, 2017

 

Recently, software-enabled appliances that support network virtualization have seen wide adoption by data centers and service providers. The main advantage of Software Defined Networking (SDN) is that the control plane is separated from the data plane, thereby allowing for network visibility, dynamic resource provisioning, and flexible service deployments. Complementary to SDN, Network Function Virtualization (NFV) focuses on virtualization of software-based network node functions, such as firewalls and intrusion detection. The increased agility and flexibility in the SDN/NFV-based network infrastructure opens up endless possibilities for multimedia content delivery and distribution. For example, virtual content delivery nodes can be dynamically deployed at the edge of the network in an on-demand fashion, potentially reducing energy costs and improving user satisfaction. This special issue aims to showcase and disseminate original research works that explore how multimedia content distribution can be supported and enhanced over SDN/NFV-based networks. Topics of interest for this special issue include, but are not limited to:

  • SDN/NFV-related architectures for next generation multimedia networks and services
  • Dynamic resource provisioning and management for SDN/NFV-based multimedia systems
  • QoE assessment for multimedia delivery over SDN/NFV-based multimedia systems
  • QoE management with dynamic policy deployments over SDN/NFV-enabled networks
  • Algorithms for live analysis and monitoring of audiovisual streaming quality in that correlates with network events in SDN or NFV-based multimedia systems
  • Real-time video adaptation algorithms over SDN/NFV-enabled networks
  • HTTP-based adaptive video streaming over SDN/NFV-enabled networks
  • Interactions between SDN/NFV architectures with content delivery networks (CDNs)
  • Applicability of SDN/NFV in mobile networks for multimedia provision
  • Integration of SDN/NFV-enabled mobile and fixed networks for multimedia services
  • Composition and deployment of Service Function Chains (SFCs) of video and/or VoIP services

713690The paper entitled as SDN/NFV-enabled satellite communications networks: Opportunities, scenarios and challenges published online at Elsevier Phycom Journal with DOI doi:10.1016/j.phycom.2015.10.007.

The paper focuses in the context of next generation 5G networks, where the satellite industry is clearly committed to revisit and revamp the role of satellite communications. As major drivers in the evolution of (terrestrial) fixed and mobile networks, Software Defined Networking (SDN) and Network Function Virtualisation (NFV) technologies are also being positioned as central technology enablers towards improved and more flexible integration of satellite and terrestrial segments, providing satellite network further service innovation and business agility by advanced network resources management techniques.

Through the analysis of scenarios and use cases, in this paper a description of the benefits that SDN/NFV technologies can bring into satellite communications towards 5G is provided. Three scenarios are presented and analysed to delineate different potential improvement areas pursued through the introduction of SDN/NFV technologies in the satellite ground segment domain. Within each scenario, a number of use cases are developed to gain further insight into specific capabilities and to identify the technical challenges stemming from them.

Guest Editor at IEEE COMSOC MMTC E-Letter (July Issue) on SDN/NFV

The July Issue of IEEE COMSOC MMTC E-Letter has just been published on-line and is for downloading here. The issue has been guest editored by Xiaoqing Zhu (Cisco Systems) and Harilaos Koumaras and provides the latest advances on SDN/NFV. More specifically, the special issue brings to our readers a collection of invited articles that address various aspects of SDN/NFV-enabled architectures for media content delivery. Authors from academia and industry share their individual perspectives regarding the opportunities and challenges brought forth by the rapid spread of SDN/NFV technologies, outlooks for the future of media content delivery in an increasingly mobile and heterogeneous environment, as well as ongoing research efforts in leveraging SDN/NFV for enhanced media content delivery.

It was really a pleasure collaborating with Xiaoqing and I believe that the outcome of our collaboration on this special issue is very good. Happy reading!!
