About video streaming (Youtube, Netflix) - aren't they based more around keeping caches "local" to the user rather than relying on inter continental communications to stream?
(honest question, as I can't understand if those 10 terabits would scale enough to be the decisive factor on the feasibility of Youtube)
- stingraycharles 10y agoWhat you are describing are so called "edge" servers, and this is indeed a technique for content distribution, but it relies on partnerships with willing ISP. You essentially set up connection "peering" with the ISP, in which you bypass expensive internet uplinks. However, I can also imagine that quite a non-neglectible proportion of Youtube/Netflix traffic cannot be retrieved from such a cache.
- bogomipz 10y agoThat's correct, this is why CDNs exist, you don't want to backhaul this volume of traffic.
