Imagine the case of Twitter Periscope or Meerkat.The paradigm of their servers is that they recieve video from users and then stream it to a large amount of users (say > 100K for the sake of this argument).

Now, here is my confusion. Let's assume a video has a bit rate of 2Mb/s (Cause we're fancy and stream 1080p@30). Also assume there is only 1 guy broadcasting.

So: this guy needs outbound bandwidth of 2Mbps (Which is OK) the server inbound bandwidth needed is also ~2Mbps (Which is awesome) however, the outbound bandwidth of the server should be 2Mbps*100K = 200 Gbps (holy cow)

The question which might be stupid to some, yet I still wonder, The connections I have seen for companies like comcast,ATT,Level3 are max 10Gbps

How do they manage such bandwidth in terms of outbound connection providers?

A 10Gbps connection per server machine? A plan which I am not aware of? Or they don't need more than 10Gbps at all?

THe connect with multiple 10g connections. OBVIOUS, is it not?

A plan which I am not aware of?

I am quite sure you are totally unaware of what is there outside what is offered to smaller customers ;)

  • But why would a company, say ATT allow multiple 10G connections but not one connection to suit all needs? – Solo Jul 27 '15 at 8:00
  • @Solo: Because networking equipment gets (kind of) exponentially more expensive with higher bandwith beyond 10Gb/s... – Sven Jul 27 '15 at 8:40
  • @Sven - Thanks! so to sum it up... You go to ATT and say you want say 50Gbps outbound and they set 5 totally independent ports of 10Gbps in your data center to their backbone, right? – Solo Jul 27 '15 at 9:18

    @Solo: To sum it up: You get someone who knows what he is talking about and they come up with a plan that makes sense for your specific scenario that also factors in things like future growth etc – Sven Jul 27 '15 at 9:25
