Our proposal requires the combined usage of three different technologies. The first one is a recent proposal by Jacobsen et al. called Content-Centric Networking (also known as Named Data Networking). It is a network architecture that introduces named data as the most valuable element in the network and divides it into so called content chunks, which are self-identifying and self-authenticating data units. The second concept we utilize derives from the approach of Dynamic Adaptive Streaming over HTTP, which allows clients to dynamically choose the quality of the received video stream according to their available resources. Finally, we adapt the concept of Broadcast Encryption to form a tool to control the access to provided content streams. The combination of these technologies enables us to design a framework that allows streaming providers to transport data to customers as dynamic adaptive encrypted content chunks, which is an efficient, flexible and scalable way of multimedia data transport.}, keywords = {Content-Centric Networking, CCN, Named Data Networking, NDN, Dynamic Adaptive Streaming, DASH, Broadcast Encryption, Video on Demand}, language = {EN}, location = {Germany, Göttingen}, pdf = {https://www.itec.aau.at/bib/files/ICNP_NPSEC_Streaming.pdf}, talkdate = {2013.10.07}, talktype = {registered} } @InProceedings{Lederer2013b, author = {Lederer, Stefan and Mueller, Christopher and Rainer, Benjamin and Timmerer, Christian and Hellwagner, Hermann}, booktitle = {In Proceedings of the IEEE ICC'13 - Workshop on Immersive \& Interactive Multimedia Communications over the Future Internet}, title = {Adaptive Streaming over Content Centric Networks in Mobile Networks using Multiple Links}, year = {2013}, address = {Budapest}, editor = {Assuncao, Pedro and Atzori, Luigi and Dagiuklas, Tasos and Kondoz, Ahmet}, month = {jun}, pages = {687-691}, publisher = {IEEE}, abstract = {This paper presents the usage of Content Centric Networking (CCN) for adaptive multimedia streaming in mobile environments, leveraging the recent ISO/IEC MPEG Dynamic Adaptive Streaming over HTTP (DASH) standard. The performance of DASH over CCN is evaluated using real-world mobile bandwidth traces and compared to previous evaluations of different DASH-based as well as proprietary systems. As there are no client-server connections in CCN, it offers the possibility to transfer data from multiple sources as well as over multiple links in parallel, which is definitely an important feature, e.g., for mobile devices offering multiple network links. This functionality is used and evaluated in this paper in combination with DASH, making it possible to dynamically choose the best performing link for media streaming, which is a clear advantage over DASH using HTTP and the TCP/IP protocol stack. The evaluation therefore investigates DASH over CCN in two scenarios using synthetic and real-world mobile bandwidth traces respectively, showing a significantly better performance than conventional DASH using only one connection.}, keywords = {MPEG-DASH, CCN, Dynamic Adaptive Streaming over HTTP, Content Centric Networking, Evaluation}, language = {EN}, location = {Budapest, Hungary}, pdf = {https://www.itec.aau.at/bib/files/ICC2013_Mobile_DASHoverCCN.pdf}, talkdate = {2013.06.13}, talktype = {registered}, url = {http://multicomm.diee.unica.it/} } @InProceedings{Lederer2012c, author = {Liu, Yaning and Geurts, Joost and Rainer, Benjamin and Lederer, Stefan and Mueller, Christopher and Timmerer, Christian}, booktitle = {CCNx Community Meeting (CCNxConn 2012)}, title = {DASH over CCN: A CCN use-case for a Social Media based collaborative project}, year = {2012}, address = {Sophia Antipolis}, editor = {Carofiglio, Giovanna}, month = {sep}, pages = {1-1}, publisher = {Parc}, keywords = {CCN, DASH}, language = {EN}, location = {Sophia Antipolis, France}, pdf = {https://www.itec.aau.at/bib/files/DashOverCCN.pdf}, talkdate = {2012.09.12}, talktype = {registered}, url = {http://www.ccnx.org/ccnxcon2012/} }
