Key Network Delivery Metrics

Streaming Video Alliance (specifically the QoE working group) released a few days ago a document describing key network delivery metrics for streaming Internet video. Although many more metrics could have been documented, these particular metrics represent the most commonly used.

Special Issue for IEEE MultiMedia

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

QoE-FI 2015

IEEE Workshop on Quality of Experience-Based Management for Future Internet Applications and Services

Recent technological advances have enabled a constant proliferation of novel immersive and interactive services that pose ever-increasing demands to our communication networks and add to their load. Examples are: social TV, immersive environments, mobile gaming, HDTV over mobile, 3D virtual world, book/newspaper consumption, social networking, IPTV applications, just to cite a few. Some of these services have already reached a major market success especially because a user-centered approach has been followed to design the whole process of content production, service activation, content consumption, and service (and network) management.
In addition, we witness the trend of migrating end-to-end multimedia communication systems/platforms to the cloud. Media processing and consumption in the cloud requires attention from two main perspectives: maintenance of processing-related cloud operations over the execution time considering the end-user and application-related QoS/QoE requirements via dynamic resource provisioning; and the parallelization and abstraction of media processing tasks for the optimization of limited and shared cloud resources. Furthermore, the domain of Smart Cities offers new opportunities and use cases, but at the same time poses new challenges for keeping users engaged and interested in those services. This also includes other aspects such as quality of life as well as critical considerations such as user safety, particularly when it comes to urban transport and emergency scenarios.
In this dynamically evolving context, network operators and service providers are struggling to keep their increasingly sophisticated customers content while remaining profitable at the same time. Consequently, optimization and management of QoE has become crucial issue in the deployment of successful services and products. However, even if the concept itself may seem straightforward to understand, it requires rather complex implementation processes for efficient performances in real end-to-end systems/networks. The complexity of QoE is mainly due to the difficulties in its modelling, evaluation, and mapping to objective Quality of Service (QoS) parameters, which,for more than a decade, has been used as a partial substitution to QoE, and due to its multi-dimensional end-to-end nature covering a wide range of networks, applications, systems, devices, contexts and expertise.

On this background, the workshop is aimed at bringing together researchers from academia and industry to identify and discuss technical challenges, exchange novel ideas, explore enabling technologies, and report latest research efforts that cover a variety of topics including, but not limited to:

– QoE evaluation methodologies and metrics
– Frameworks and testbeds for QoE evaluation (crowd-sourcing, field testing, etc.)
– QoE studies & trials in the context of Smart Cities
– QoE models, their applications and use cases
– QoE for immersive audio-video and interactive multimedia communication environments
– QoE-aware cross-layer design
– QoE-driven media processing and transmission over the cloud and over the top (OTT)
– QoE control, monitoring and management strategies
– QoE in community-focused interactive systems
– KPI and KQI definition for QoE optimization in different environments
– Integration of QoE in infrastructure and service quality monitoring solutions
– Media analytics from QoE Big Data
– Standards for media coding (HEVC, HEVC for 3D, etc.) and transport (DASH, MMT, XMPP, etc.)
– Future Media Internet architectures
