Broadcast television in an IP world

Tue Nov 21 15:09:06 UTC 2017

Unicasting what everyone watches live on a random evening would use significantly more bandwidth than Game of Thrones or whatever OTT drop. Magnitudes more. It wouldn't even be in the same ballpark. 

Not all networks are capable of unicasting all live-viewed TV content, but they do literally everything else required of them.

The point is that you need to build the network to handle peak load of OTT 
streaming. If the network can handle major releases like a new season of 
Game of Thrones, then the network has the capacity to handle live events 
streamed the same way. It does not matter how you paid for that capacity. 

If you truly want to save a buildout at the edge, you need cache servers 
deeper into the network. 

Game of Thrones might not be as big as Super Bowl, but we will get there 
eventually. When we do, there is money to be saved by only managing one 
type of network (unicast).
