This kind of streaming technology is mainly used with HTTP 1.0 and 1.1 respectively, which both have some drawbacks. Therefore, the IETF has started the development of HTTP 2.0, which is based on Google’s SPDY proposal and already supported by several major companies, e.g., Facebook, Twitter, Akamai, Mozilla and obviously Google. Furthermore, Content Centric Networking (CCN) is another novel approach for future networks that is considered as an revolutionary approach compared to HTTP 2.0. The CCN communication paradigm is completely different and does not rely on direct connections between hosts, it rather focuses on the content. This paper demonstrates DASH with HTTP 2.0/SPDY and CCN using our universal libdash library. Moreover, different mechanisms of DASH will be shown that can be used to provide on-demand and live content in an efficient and comfortable way.}, language = {EN}, location = {San Jose, USA}, pdf = {https://www.itec.aau.at/bib/files/libdash-demo.pdf}, talkdate = {2013.07.18}, talktype = {poster} } @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{Crabtree2013, author = {Crabtree, Barry and Stevens, Tim and Allan, Brahin and Lederer, Stefan and Posch, Daniel and Mueller, Christopher and Timmerer, Christian}, booktitle = {CCNxConn 2013}, title = {Video Adaptation in Limited or Zero Network Coverage}, year = {2013}, address = {Palo Alto}, editor = {Mahadevan, Priya}, month = {sep}, pages = {1-2}, publisher = {PARC}, abstract = {This paper shows how adaptive streaming and on-device caching can be used to provide an always available video service.
