they do this with DNS changes for client requests... pushing a customer to an endpoint reachable across one path vs another. (added for clarification only)
If a pop has 174 3356 2914 7992 transit(s) chances are they can use any one of them or all of them to get to foo other large transit as.Yes, but no matter which network Netflix uses as an exit from their network, Verizon still has the final say on how it enters Verizon's network. If
not really? verizon's held (for relationships they call 'settlement free interconnects') to a standard that includes essentially equal announcements across all common interconnects. Ideally this means vzb announces all 10,123 routes across all of the interconnects between 701 and network B...
Netflix has several transit providers to choose from, at best they can try each one and see what delivers the best experience to their mutual
yup, netflix has some idea that "At time T path X-Y-Z-701 is better than A-B-C-701" so they force some set of customers across this path as best they can by telling these customers taht X-Y-Z-701.stream.netflix.net == 1.2.3.4 is the right name/address mapping for the content requested. If something happens during the dns TTL / decision process to change DNS with traffic across the X-Y-Z-701 path though... it's not clear to me that netflix can affect those active streams. If the pathway goes away sure things shift around, if the path just gets congested... whoops. On top of this, there are lots of folk over the peering-wars-years that have shown they can influence peering discussions one way or the other by pushing traffic across distinct points in the as graph, then making press-hay about the mistreatment they are receiving. (NOTE NOTE NOTE: I have no idea if that's going on, I'm just making the point that this very clearly has happened in the past with other players)
customers. Of course, Verizon might change their routing policy tomorrow (or on-demand) and throw that all out of whack. My point is that Verizon advertises several ways to reach Verizon's network. If one path is 'inneficient' as Verizon states, Verizon is at fault for announcing that inefficient path. Netflix does not dictate Verizon's border routing policy, contrary to Verizon's claims.
it's not the inefficiency of the path, it's the (probably, maybe) difference in capacity available vs other/alternate paths. -chris
