Could Netflix change its video streaming service to use a P2P architecture, in order to save money on content delivery and sidestep peering conflicts with ISPs like Comcast?
That’s a possibility raised by Netflix CEO Reed Hastings in a blog post Thursday, which urged the FCC to make peering part of new net neutrality regulations. ISPs want Netflix to pay for delivering traffic to their customers because the company doesn’t consume as much traffic as it delivers — to which Hastings replied: “Interestingly, there is one special case where no-fee interconnection is embraced by the big ISPs — when they are connecting among themselves. They argue this is because roughly the same amount of data comes and goes between their networks. But when we ask them if we too would qualify for no-fee interconnect if we changed our service to upload as much data as we download (in other words, moving to peer-to-peer content delivery) — thus filling their upstream networks and nearly doubling our total traffic — there is an uncomfortable silence.”
This brings up an interesting question: Could Netflix actually do that?
Avec le passage au full HD et bientôt à la 4K de a diffusion OTT, le modèle de distribution unicast montre ses limites. La course à l’armement des CDNs dans le déploiement de baies de serveurs et la multiplication des points de peering n’est pas scalable à l’infini, et pourtant le traffic vidéo ne cesse d’augmenter de manière exponentielle, y compris – et surtout – sur les terminaux mobiles. La recherche de modèles de distribution OTT complémentaires avec le multicast est donc une priorité pour continuer d’assurer la qualité de l’expérience utilisateur et optimiser les coûts de diffusion. Les regards se tournent de plus en plus vers le transport multicast qui a fait le succès de l’IPTV, ainsi que le Peer-to-Peer qui, malgré sa réputation sulfureuse, a déjà fait ses preuves pour la diffusion de chaines live OTT à très grande échelle. Pour tout savoir du multicast et du P2P, et apprendre des retours d’expérience et de recherche des membres de la Squad qui travaillent sur ces systèmes hybrides, OVFSquad organisait le 23 janvier 2014 une soirée spéciale de présentations (aka « Conférensquad ») dont voici le compte-rendu et les présentations.
BitTorrent has just posted a call for broadcast engineers to help with the building of BitTorrent Live.
BitTorrent Live is a new peer-to-peer live streaming protocol. It allows content creators to scale their reach to audiences of millions with near-zero latencies and minimal infrastructure investment.
“Built with users, from scratch, it’s designed to take the principles of the BitTorrent protocol, and apply them to streaming,” according to BitTorrent’s call to broadcasters, “That means: no barriers to broadcast. That means: the more people who tune in, the more resilient your stream. That means: you can share video with a massive audience, in realtime – without bandwidth costs or infrastructure requirements.
Minimizing Server Throughput for Low-Delay Live Streaming in Content Delivery Networks (F. Zhou, S. Ahmad, E. Buyukkaya,R. Hamzaoui and G.Simon)
Paper "Towards Peer-Assisted Dynamic Adaptive Streaming over HTTP" from the IEEE International Packet Video Workshop 2012
Television is going the way of the dinosaur, and the deadly comet is called BitTorrent Live. Today, Bram Cohen, the author of the BitTorrent peer-to-peer sharing protocol, demoed his latest creation at the SF MusicTech Summit.
BitTorrent Live lets any content owner or publisher stream video to millions of people at good quality and with just a few seconds of latency…for free or cheap. Sports, news events, simulcast TV shows, education, video conferencing, or uncensored war zone broadcasts — this technology will power the future of video.
“My goal is to kill off television” Cohen said during the SF MusicTech demo session I hosted. Afterwards he explained to me in rhyme, “Television’s physical infrastructure is inevitably going to go away, but TV as a mode of content consumption is here to stay.” Essentially, people love what they see on television, but want it accessible from the web.
GoalBit is a free open source video streaming platform capable of distributing high-bandwidth live video content to everyone preserving its quality. Goalbit Media Player basic features : - Is free software, released under the GNU General Public License. - Runs on Microsoft Windows, GNU/Linux and Solaris. - Supports different video sources such as files, digital video/webcam/acquisition cards , HTTP/MMS/RTP Unicast/Multicast streams, DVD/VCD/SVCD devices. - Support for H.264/AVC, Theora, , MPEG-4/2/1, WMV video formats. - Optional BitTorrent like streaming. - Follows the IETF standard PPSP, Peer To Peer Streaming Protocol.
Octoshape announced today its integration with Ecrin Video & Broadcast's video contribution and distribution systems. The integration of these technologies facilitates point-to-point and point-to-multipoint contribution and playout over the Internet as well as mass consumer distribution. French-based Ecrin supplies H.264 encoding systems that deliver content for broadcasters, IPTV, webTV and mobileTV. Octoshape's Infinite Uplink embedded technology replaces traditional satellite and video fiber systems with resilient video contribution over the Internet, drastically reducing the cost associated with distribution and increasing deployment flexibility. This functionality, combined with Ecrin's LiveStream Series solution set, opens up new markets traditionally served only by large satellite delivery providers.
Multicast provides broader reach and optimized distribution without network upgrades
Streaming media innovator Octoshape ApS today demonstrated emerging Multicast service options for broadcasters and telcos looking to deliver over-the-top (OTT) TV with the highest quality of service to large consumer audiences without expensive network upgrades.

4K streaming, mobile broadcasting for the crowd, generalized delinearization, worldwide video events…
OTT delivery is just multiplying the challenges, as customers’ expectations are raising each day in terms of video fast-start, instant channel switching, lack of buffer and high frame size/rate – on all devices in all network conditions. To answer those challenges, OTT delivery answer today is basically more unicast sessions, more servers, more peering – and less and less guarantee of satisfying end-user experience as long as there is no specific end-to-end paid agreement to guarantee that the path will be provisioned from the origin server up to the video device. Even in this ideal scheme, the device might still suffer from poor wireless conditions which jeopardize the experience. So, how do we deal with all this stack of potential problems: do we stick to the aging receipts, rely blindly on Moore’s law and perpetuate a hopeless CDN weapons race? Or do we try to find smarter ways to make the OTT growth reach a sustainable delivery model ?
Today Michael Thornburgh, Sr. Computer Scientist at Adobe, submitted a specification for Adobe’s Secure Real-Time Media Flow Protocol (RTMFP) to the Internet Engineering Task Force (IETF) Internet-Drafts repository ( http://tools.ietf.org/html/draft-thornburgh-adobe-rtmfp ;) along with a disclosure of and grant of essential intellectual property rights under royalty-free terms ( https://datatracker.ietf.org/ipr/1942/ ;). RTMFP is a low-level endpoint-to-endpoint data transport protocol designed for real-time and peer-to-peer (P2P) communication. It presents a unified and holistic solution to a number of Internet communication problems, including security, NAT traversal, congestion control and prioritization of parallel media and data flows, variable transmission reliability for messages, and IP address mobility.
Sporting events have long driven innovation in video distribution. It was boxing in the mid-70s (e.g. “The Thrilla’ in Manila”) that introduced large-scale satellite video transmission to the Pay TV industry. More recently, the 2008 Olympics in China was the occasion for the first highly scaled use of adaptive bit rate (ABR) streaming. Epic TV, owned by Nordic communications service provider Elisa, is an example of the latter. As recently announced, Elisa has built out a 15-country CDN with help of Edgeware to bring its online mix of premium adventure sports video to the European market. What has not been reported is Elisa’s partnership with a global CDN provider to reach even further afield. “We do work with Epic TV,” said Jason Thibeault, Senior Director at Limelight Networks.
Octoshape, a company involved with cloud-based global streaming technologies, has launched a service offering deployment of multicast over broadband for high quality linear video delivery using its unique Infinite HD-M technology. The Infinite HD-M service was developed from a proof of concept where the company powered the First Global Internet Multicast Event. Infinite HD-M leverages and enhances industry-standard multicast infrastructure, allowing carriers and operators to utilize existing hardware and capital deployments instead of investing in new proprietary content distribution platforms. This new service enables the most predictable, affordable, and scalable prices for linear broadcasters by being the first technology to enable reliable multicast over best effort networks combined with a pricing model that is easy and simple to understand.

Akamai could soon begin leveraging peer-to-peer (P2P) technology to enable its media customers to stream live or on-demand videos to end users. While Akamai has been experimenting off and on with P2P ever since its acquisition of Red Swoosh way back in 2007, the introduction of video streaming through its NetSession client-side technology might finally be close to release.
