Re: Too much effort for too little reward

the stream was provided by level3. you vastly underestimate the capacity of the core networks. Netflix streaming costs are a tiny fraction of their overall costs. licensing is a much bigger cost. it costs less than a penny to stream 1 gb.

I believe you're misunderstanding the premise of the argument. Netflix is streaming to ~300K people at a time, the SuperBowl had 117.7 million people watching at one point.

Even if you somehow got the video stream down to 1mbps and that was acceptable to everyone, you'd still be looking at 117,700,000megabit to stream that to everyone. Keep in mind the biggest interface you can get in network equipment today is 100gigabit (at a cost of $80k+ per port), and for servers you're only going to be able to economically deliver 10gig interfaces.

So to meet 117.7TERAbit, you'd have to spread that across a minimum of 11,770 server interfaces to stream the video. If you want to match Netflix average streaming rates of 2mbps, that's 235.4TERAbit, or 23,540 server interfaces. Hell, even if just 1% of people who watched the SuperBowl tried to stream it, it would still be QUADRUPLE what Netflix streams on a nightly basis.

To put this in perspective, to stream 2mbps to the average nightly 300k Netflix subscribers you're only looking at 600GIGAbit of aggregate traffic. This is obviously a much more reasonable minimum of 60 x 10Gig server interfaces to kick out those streams.

Level(3) does indeed have a ton of capacity, but you have to be delusional to think they're sitting on a couple hundred terabit of capacity waiting to stream things.

Nope. They're bullying Comcast into giving it to them for free and crying mommy to the FCC when they don't get what they want.

This is why we have multicast.

While you are correct multicast was designed to solve this problem of uniform distribution, there is no practical support for multicast on the public Internet.

Seriously...I've been giving some thought to this since I saw this article. It's probably a lot to ask that Internet providers have a reasonable multicast implementation, especially for more than a single segment (such as a single CMTS).

I wonder if it would be feasible to distribute session encryption keys much the same way they're determined/exchanged for IPSec (IKE). This sort of thing alone (IP broadcasting) could be the single biggest, best reason to transition to IPv6 as quickly as possible. The more vast address space would be necessary to implement something like the ability to send specific multicasts...not just well-known ones like NTP, RAs, and such. Imagine if you will that ABC, NBC, CBS, Fox, USA Network, Lifetime, HBO, SyFy, Discovery, etc. all had their own multicast address, and that all one has to do is send messages to join the multicast group, possibly also doing some sort of encryption key exchange if necessary for entitlement purposes.
