Assisted DASH-aware networking over SDN-CCN architecture

摘要

High bandwidth demand is incited by online video streaming that has become a fundamental of many consumers' lives. To provide the best user experience taking into account the user device and the network available bandwidth, different new technologies have been proposed. MPEG Dynamic Adaptive Streaming over HTTP (DASH) is considered among the most used technology of video delivery nowadays. DASH standard is based on rate adaptation on the client side. However, to enhance the DASH delivery there is a growing need for new network architecture. Two main trends are investigated in the literature: integration of DASH over ICN/CCN architecture which allows in-network caching, and performing DASH streaming over SDN architecture to control network delivery. In this paper, we discuss the necessity and feasibility of a new hybrid architecture based on the combination of SDN and CCN to provide assisted DASH-aware networking which enables networks configuration according to the requirements of end users, network administrators and Internet service providers. Hence, our architecture allows the improvement of the Quality of Experience and the Quality of Service thanks to the SDN and CCN processes integrated.
