QoE Monitoring with VNFs (Virtual Network Functions) in the Cloud05.01.2018
QoE Monitoring VNF is now available at https://go.uniwue.de/qoevnf. The VNF QoE monitoring is a plain software that exploits a C++ library, namely libtins to capture the un-encrypted video flows at network interface. The captured packets are then parsed to feed all necessary information for the video buffer estimation algorithm, such as IP address, TCP header and the payload of application layer protocols.
In order to consider Quality of Experience (QoE) for orchestration and consolidation in a cloud management architecture, proper QoE monitoring functions are required. They can be applied either in long term or short term management components and provide the platform with information about the service quality perceived by the end users.
