P2P streaming

European Broadcasting Union (EBU) recommends P2P streaming

Strangely enough, they do not insist on:
  • You need administrator access (which most corporate users don’t have) to install Octoshape plug-in on your computer.
  • Your firewall must be configured to let Octoshape plug-in through.
  • ISPs do bandwidth throttling to restrict P2P applications
  • You are basically asking your end-users to use the bandwidth they pay for so you can save money
  • content producers are reluctant to have their content distributed through end-users computers

Elsewhere in that EBU Technical Review:
Several users had problems with downloading the Octoshape plug-in. Some people, particularly those located in large corporations (including some large broadcasting organizations) could not download the plug-in at all, and consequently were not able to access the Portal services.

These EBU tests cannot be considered rigorous scientific tests. They were more akin to “proof of concept” and “experience-gathering” evaluations. Octoshape is not the only commercial P2P system available in the market but we selected it because our previous experience with this system was positive.

Does anyone know what is the relationship between Octoshape and EBU? What’s the credibility of this “technical review”?

Go read the full EBU Technical Review and make sure you do a search for the keyword “firewall”. It’s surprising to say the least that this issue isn’t even mentioned.

It seems that Octoshape has been lobbying with EBU for a few years.

At the Streaming Media West 2008 conference I attended a panel where questions were asked about P2P to Limelight and EdgeCast.

(from 41:00)
Phil Goldsmith (COO, SVP Sales, EdgeCast Networks)
Paul Alfieri (Limelight Networks) : “Our customers are not asking for P2P and it’s mainly a security issue.”
It gets even more interesting as Dan Rayburn jumped in at the end of the debate (53:20).
You can disagree with me but I felt like showing the flip side of the coin.
