Abstract

The provisioning of the quality to end users is a major objective for the successful deployment of multimedia services over the Internet. It is more and more evident from past research and service deployments that such an objective often requires a collaboration among the different parties that are involved in the delivery of the service. This paper specifically focuses on the cooperation between the Over-The-Top (OTTs) and the Internet Service Providers (ISPs) and proposes a novel service delivery approach that is purely driven by the Quality of Experience (QoE) provided to the final common users. Initially, we identify the need of the collaboration among the OTTs and the ISPs where we not only highlight some of the enterprise level motivations (revenue generation) but also the technical aspects which require collaboration. Later, we provide a reference architecture with the required modules and vertical interfaces for the interaction among the OTTs and the ISPs. Then, we provide a collaboration model where we focus on the modeling of the revenue, whose maximization drives the collaboration. The revenue is considered to be dependent on the user churn, which in turn is affected by the QoE and is modeled using the Sigmoid function. We illustrate simulation results based on our proposed collaboration approach which highlight how the proposed strategy increases the revenue generation and QoE for the OTTs and the ISPs hence providing a ground for ISP to join the loop of revenue generation between OTTs and users.

7. Conclusion and future work

In this paper, we proposed a novel approach for collaborative QoE management between OTTs and ISPs. Differently from QoS based collaboration models found in literature as ALTO and CINA, the proposed collaboration approach is completely QoE centered based on maximization of revenue. Moreover, the proposed model also takes into account important factors such as the user churn, pricing and marketing, making it novel. Also, with the consideration of the different QoE models for different applications we investigated the flexibility and adaptability of our collaboration model which has proven to be robust, reliable and adaptable with respect to any change in QoE model. Furthermore, with simulations we highlighted that if ISPs and OTTs adopt the proposed collaboration approach they will not only increase the revenue but will also provide better QoE to their users with relatively lower prices.
