Downsides of HTTP adaptive bit rate streaming

I wrote a number of articles about the shortcomings of HTTP Adaptive Bit Rate Streaming (HABS). 

Jet-Stream R&D identified another number of issues that cripple massive adoption of these technologies:

Only 18% Using Adaptive Streaming

Mobile cloud computing company Skyfire has released a report finding that out of the top 100 global video websites, only 18 percent currently use adaptive bit rate (ABR) technologies for streaming.

Adaptive bit rate is theorized to ease congestion by switching down in quality depending on network conditions and device feedback. But in reality adaptive bit rate increases the network load since it can aggressively scale up to much higher bit rates and flood mobile and fixed networks.

Adaptive bit rate streaming is not new. For over ten years, RealNetworks and Microsoft have offered multiple bit rate streaming that adapted to the clients bandwidth. What differentiates todays adaptive bit rate streaming is that it is not a fluent stream but a burst of downloaded video chunks, allowing the technology to be more aggressive in upscaling and downscaling quality.

HTTP adaptive streaming causing mobile problems

During CDN World Summit, mobile network experts shared their concerns about HTTP Adaptive Bit Rate Streaming. According to radio experts, the technology disrupts the radio signaling.

Radio bandwidth is one challenge, but another challenge in mobile networking is the signaling: signaling is basically the process of establishing, controlling and managing radio communication. Mobile networks have limitations in the number of signals they can process...

Announcement: Jet-Stream CDN v10.6

Jet-Stream is finalizing the R&D cycle of a new version of our next generation CDN technology.

The JetStream CDN technology has its roots from the mid nineties and has had three major design overhauls and full recoding since then. V10.6 is the sixth large enhancement since our latest full recoding (v10.0) in 2008 and adds many new features to the proven and extreme stable existing codebase. Jet-Stream has a very strict R&D cycle and release policy with just one codebase to support all operational CDNs in the field. We don’t ‘hack’ exceptions for specific customers or PoCs. This policy guarantees very stable code, better future scalability, robustness, leading response to industry trends and fast innovation.

The technology has been designed from the ground up for telecom operator usage and operation. Some unique features are multi-delivery-vendor support, the advanced content distribution engine, the advanced request routing engine, the advanced log processing engine, our professional web management interface, our professional content owners self service interface, content workflow integration APIs, easy integration with existing telecom operator NOCs and open integration with third party statistics and analytics tools. The result is a much more efficient, better manageable and more premium CDN solution that does not only respect telecom operators requirements but also better meets the requirements of content publishers, giving them much more control, transparency and insight over their precious content.

Version 10.6 will be officially released on Content Delivery Summit, Monday 17 October, in London and is a major upgrade with many new features that focus on:

Advanced CDN architectures; true CDN federation preparation; enhanced robustness and scalability for even more premium CDN services; advanced and intelligent HTTP adaptive ingest, caching and delivery; enhanced distribution intelligence; and scalable log processing.
