Giraffic is also the inventor of DAS: Its multi-patented Distributed Adaptive Streaming™ (DAS) technology – a fully automated virtual Content Delivery Network that enables crowd sourcing of the excess and idle bandwidth from millions of end-user devices to provide a high quality, robust and highly efficient collaborative content streaming cloud.
By deploying DAS for content delivery or for software/firmware updates, device manufacturers can offload over 70% of the bandwidth while avoiding disruptive internet bottlenecks.
Giraffic Distributed Adaptive Streaming™ is a robust fully distributed cloud, leveraging the universal presence of end-users and infinite fragments of resources they can provide to the community, together with sophisticated data and streaming management algorithms.
The core of the solution is a new UDP based streaming protocol that can retrieve data from multiple sources simultaneously in random order, without latency, at a fraction the time and cost of existing content delivery solutions.
No matter what Video Infrastructure you are using, just add the Giraffic’s Distributed Adaptive Streaming™ to your app or content service in order to increase end-user streaming performance, video quality and offload immediately 80% of your bandwidth needs.
Giraffic’s DAS can be added on to standard HTTP progressive download, or to the variable bit-rate formats such as HDS, HLS, Microsoft Smooth Streaming and MPEG-DASH, which immediately enables higher video quality and smoother bitrate transitions on the end-users’ existing Internet connection.
Offloading over 80% of customer’s bandwidth and absorbing peak-hour traffic:
The following chart is real live customer’s data from Giraffic’s network during a typical week of operations – demonstrating Giraffic’s ability not only to offload over 80% of the total customer data (!), but also how Giraffic’s network absorbs the majority of peak traffic and leaves the operator’s network and CDN “Flat”.
Legend: The BLUE line shows the data offloaded by Giraffic, while the RED line is the data coming from the CDN.
Adding Giraffic DAS on top of Variable Bitrate Formats such as HLS, SmoothStreaming, HDS and MPEG-DASH, has demonstrated:
End users gain substantially the higher resolution (bit-rate) on their existing Internet connection – the highest quality/bitrate supported their own Internet connection, removing any other network or backbone bottlenecks.
With HTTP only (Giraffic off – before the yellow line), playback resulted in 500kbps to 1Mbps quality and was jumpy and inconsistent.
With Giraffic turned on (after the yellow line), the video was played at 1-1.5Mbps, and much more stable as well as consistent Quality-of-Service.
The network behavior recorded during a typical adaptive playback is stipulated in the chart bellow:
