We are happy to provide a DASH over ICN/CCN-enabled version of libdash. We also contributed our DASH over ICN/CCN approach to the ICN Research Group (ICNRG), presented in this input draft: draft-video-streaming-over-ICN-00.txt and the associated slides.

You can find more information, build-instructions and test setups on this website (here) as well as in the DASH over ICN-branch of the libdash repository on github: https://github.com/bitmovin/libdash/tree/CCN. There you can also find instructions for streaming DASH content via CCN from (1) a local repository and (2) from the public available CCN Node ccn.bitmovin.net

Please help us and vote for our libdash library as best MPEG-DASH product in the reader’s choice award voting of Streaming Media. As you probably know, libdash is the reference library of the MPEG-DASH standard and is the enabler for DASH on various platforms.

Thanks a lot!

We presented our adaptive video over ICN research in the ICNRG at the 87th IETF Meeting in Berlin. Here you can find our presentation:
Title: Adaptive Video over ICN
Authors: Stefan Lederer, Christian Timmerer, Cedric Westphal and Christopher Mueller
Abstract: This document presents the usage of Information Centric Networks (ICN) for adaptive multimedia streaming and identifies problems which have to be considered for such applications. As solution DASH over ICN is presented, which leverages the recent ISO/IEC MPEG Dynamic Adaptive Streaming over HTTP (DASH) standard. DASH over ICN 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. In addition to this, the named multimedia content is routed and cached efficiently by the underlying network.

Title: Dynamic Adaptive Streaming over HTTP/2.0
Authors: Christopher Mueller, Stefan Lederer, Christian Timmerer and Hermann Hellwagner
Abstract: MPEG Dynamic Adaptive Streaming over HTTP (DASH) is a new streaming standard that has been recently ratified as an international standard (IS). In comparison to other streaming systems, e.g., HTTP progressive download, DASH is able to handle varying bandwidth conditions providing smooth streaming. Furthermore, it enables NAT and Firewall traversal, flexible and scalable deployment as well as reduced infrastructure costs due to the reuse of existing Internet infrastructure components, e.g., proxies, caches, and Content Distribution Networks (CDN). Recently, the Hypertext Transfer Protocol Bis (httpbis) working group of the IETF has officially started the development of HTTP 2.0. Initially three major proposals have been submitted to the IETF i.e., Googles’ SPDY, Microsofts’ HTTP Speed+Mobility and Network-Friendly HTTP Upgrade, but SPDY has been chosen as working draft for HTTP 2.0. In this paper we implemented MPEG-DASH over HTTP 2.0 (i.e., SPDY), demonstrating its potential benefits and drawbacks. Moreover, several experimental evaluations have been performed that compare HTTP 2.0 with HTTP 1.1 and HTTP 1.0 in the context of DASH. In particular, the protocol overhead, the performance for different round trip times, and DASH with HTTP 2.0 in a lab test scenario has been evaluated in detail.

We have recently enabled HTTP/2.0 (SPDY) support in an own branch [1]. Additionally, we provide a part of our DASH dataset over HTTP/2.0 (SPDY). The MPDs are already included in the sample media player of libdash and available here.
