Abstract

Recent studies implemented collaboration between Over-The-Top (OTT) service and Internet Service Provider (ISP) concerning information exchange between the providers. This information is used to accurately predict the delivered Quality of Experience (QoE) and decide the correcting network management actions. In this scenario, we aim to investigate the impact of the frequency of information exchange between OTT and ISP on end users' QoE and network resource utilization. Firstly, we propose our information-centric QoE-aware collaborative service management approach by defining the type of information to be acquired and exchanged between OTT and ISP. Secondly, we present our platform based on the Software-Defined Networking (SDN) paradigm, which we used to conduct the experiments. Finally, we conduct experiment results that compare the proposed collaborative approach with the case of no collaboration when the sampling interval of information exchange varies between 2 s and 32 s. The experiment results show that a higher frequency of information exchange may result in better network reliability and delivered QoE, but a frequency higher than 1/4 Hz may not further improve the delivered QoE.
