I'm curious how CW does it? non live streaming has to be expensive as hell! Live streaming by contrast should be super cheap - multicasting - one stream out sent to all subscribers.

That's not how networking works.

Live cannot be cached and the full data load has to be delivered everywhere, all at once. Multicasting is a mechanism for that, but not a panacea. They are still on the hook for all of that data.

Of course they are - though I'm not sure exactly what you mean "all of that data" - do you mean the single stream they send out? in that case of course I say - duh.

It's NOT a single stream, that's the thing. It's a stream to every end user. Multicast can't change that.

really? that's not how I understood multicast to work.

As I understand it - devices subscribe to a multicast channel (I'm sure this is the wrong word). Then the routers and switches pass the single outgoing multicast to the subscribers.

So, again as I understand it, the source sends out one stream, the upstream routers send copies to all subscribed upstream routers, who again send copies to all of their upstream subscribers, etc etc until the file router sends it to their locally subscribed end users.

Is that completely wrong?

That stream would have to be big enough to support every user.

Imagine 100 people in your house trying to use a 56K dialup modem.

@Dashrender right, but they take in millions per month from ads, and having shows on demand (theoretically) can grow the audience, ergo more ad dollars...

Exactly. They make money for every minute viewed. The more minutes, the more profits. And the profits on "on demand" is higher than the profits on "live". The math is simple.

Ads easily pay for either type, but live is slightly more expensive all around to do.

OK I did forget this point - the fact that they can charge per on demand stream - so their income would grow as their viewership of on demand grows....

While I think I understand what you're saying it's not really paramount to where I was going. No wait - actually it is. and with my original comment still stands - if all the data was coming from a single source, Yes the vendor would need a pipe large enough to handle all of those..

But the CDN is basically exactly what I'm saying is still needed - it's not one HUGE pipe - it's thousands of pretty good sized pipes. that connection still has to be paid for.

So - Why is it cheaper to use the CDN than it is to just stream from your own mega pipe? probably back to the peering points. making those large enough to handle all that direct traffic is likely more expensive than hosting and delivering closer to the end user.

Because you can order a CDN pipe automatically and turn it off once demand goes down. That is how CDNs are designed. For literal on-demand use, and I need more pipes, give me more this second.

Right. So no matter how expensive it is, it's never more than the profits.

For all the reasons that I listed. Lower cost times, alternative network options, out of band data shipping, heavier compression, etc.

Which I was alluding to by the end of my post.

Vaccinations jump 500% in antivax hotspot amid measles outbreak

“I would rather it not take an outbreak for this to happen.”

As of February 6, the county—which sits just north of the border from Portland, Oregon—has tallied 50 confirmed cases and 11 suspected cases of measles since January 1. The case count is rising swiftly, with figures more than doubling in just the last two weeks. On January 18, the county declared a public health emergency due to the outbreak.

I'd like to get a head count of these outbreaks and find out how many who got Measles have been vaccinated and how many haven't.

RojoLoco

@dafyre not sure about Houston, but Portland is full of anti-vaxxers, so my money is on the outbreak is only affecting those people (the woo-woo hippies who don't trust peer reviewed science).

Houston has a lot of very poor and the Texas healthcare system is definitely set up to make it hard for them to get assistance, so it is easily nothing more than that.
