In particular, video segments formatted according to MPEG-DASH are available in different quality levels but instead of HTTP, CCN is used for referencing and delivery. Based on the conditions of the network, the DASC client issues interests for segments achieving the best throughput. Due to segment caching within the network, subsequent requests for the same content can be served quicker. As a result, the quality of the video a user receives progressively improves, effectively overcoming bottlenecks in the network. We present two sets of experiments to evaluate the performance of DASC showing that throughput indeed improves. However, the generated overhead is relatively large and the adaptation strategy used for DASH that assumes an end-to-end connection could be revised for the hop-by-hop architecture of CCN.}, keywords = {Content Centric Networking, Dynamic Adaptive Streaming, HTTP Video Streaming, MPEG-DASH}, language = {EN}, location = {Budapest, Hungary}, pdf = {https://www.itec.aau.at/bib/files/ICC2013 -DASH Over CCN.PDF}, talkdate = {2013.06.11}, talktype = {registered}, url = {http://www.ieee-icc.org} }
