To guarantee user satisfaction, one of the key concepts of the Internet as we know it is bandwidth sharing. While this concept is necessary to provide stability in the network, several issues can arise with adaptive multimedia streaming, e.g., efficiency and stability. Considering Information-Centric Networking (ICN) and its network-inherent caching, those issues tend to become worse. Many researchers have proposed to use traffic shaping on the server to enable fair bandwidth sharing and stabilize clients. However, existing research does not consider content popularity and in-network caching. The contribution of this paper is two-fold. First, we propose a cache-aware traffic shaping policy, in order to guarantee seamless playback of videos. Second, based on content popularity, we calculate an average video quality achieved by this traffic shaping policy for various cache sizes, to show the impact of popularity and caching for multimedia streaming in ICN.}, series = {ICMEW '15}, doi = {10.1109/ICMEW.2015.7169763}, keywords = {Content Popularity; Adaptive Multimedia Streaming; Information-Centric Networking; Traffic Shaping}, pdf = {http://www-itec.uni-klu.ac.at/bib/files/music_modelling_streaming_revision1_v3.pdf} }
