Tobias Hoßfeld, University of Würzburg, tobias.hossfeld@uni-wuerzburg.de
ObjectivesThe goal of this WG1 task force is to improve the understanding and management of the Quality of Experience of Web and Cloud services along the entire provisioning-delivery chain. To this end, the taskforce will work towards bringing the more user-oriented and abstract aspects of QoE as understood by the Qualinet community to the practical applications envisioned by the QoS community, in particular those related to cross-layer QoE monitoring and management.  Likewise, it will encourage the consideration of the practical aspects of QoE modeling by the Qualinet community, in order to achieve workable QoE models that can be applied in real-life scenarios and Web/Cloud applications interesting for network and content providers.
Deliverables– Identification of different QoE optimization strategies and corresponding deployment challenges
– QoE models and QoE assessment approaches for OTT content delivery, interactive Web applications and cloud service provisioning
– Evaluation of influence factors and adaption strategies for HAS (HTTP adaptive streaming)Applications of QoE models in large scale networks analytics and cross-layer management
– Mechanisms for integrating QoE models into cross-layer network/application management schemes
– Initiate & Participate in joint SPEC & Qualinet research group with open meetings, focusing on QoE metrics and models towards QoE monitoring and management
– Build a strong QoE & Networking Community.

TF4: Qualinet Databases

NameQUALINET Databases – Dissemination and Standardization
LeaderKarel Fliegel, Czech Technical University in Prague, fliegek@fel.cvut.cz
Lukas Krasula, Netflix, Los Gatos, USA, lkrasula@netflix.com
Werner Robitza, TU Ilmenau, werner.robitza@gmail.com
ObjectivesThe main objective of the TF is to ensure the sustainability of QUALINET DBs. The legacy platform (2012-2020) available from the Czech Technical University in Prague has been replaced with a new future-proof, open-source, GIT-based platform (https://qualinet.github.io/databases/) and (http://dbq.multimediatech.cz/). 

The visibility of the QUALINET DBs will be increased through proper dissemination and standardization activities. Dissemination activities are already established within the dataset tracks of QoMEX and MMSys conferences. A similar model of cooperation will be supported by the TF in the case of other suitable events. The TF will provide updated materials (e.g. leaflet, database description, presentation) and make them available at QUALINET DBs website. The TF will continue with dissemination also through other channels, such as various email reflectors and social networks. Broad participation of all QUALINET partners in this dissemination effort is expected. Regarding standardization activities, the objective of this TF is to support joint efforts of QUALINET partners interested in standardization of their datasets within suitable standardization bodies. 

Mandates:
– Ensure sustainability of the QUALINET DBs
– Implementation and maintenance of a new open-source online platform for QUALINET DBs
– Strengthening dissemination efforts at suitable events through already established and new initiatives
– Regular updates on new datasets available within QUALINET DBs
– Creation and update of promotional materials on QUALINET DBs
– Support joint efforts of QUALINET partners interested in the standardization of their datasets
