That will not help. Let's assume you get to the same host, in LA. You're in NY, with FIOS. Your VPN host is, well, let's run two examples, one with it in Chicago, and one ALSO with it in NY, but with some neutral ISP. You w/FIOS: NETFLIX(LA) -> SoCal Peering Point -> VZN IX Host LA -> VZN HOP (midwest) -> VZN HOP (northeast) -> VZN HOP (NYC) -> VZN (neighborhood) -> You You w/Chicago VPN NETFLIX(LA) -> SoCal Peering Point -> Backbone IX Host LA -> Backbone HOP (midwest) -> ISP (Chicago) -> VPN Host -> ISP (Chicago) -> Midwest Peering Point -> VZN IX Host Midwest -> VZN HOP (midwest) -> VZN HOP (northeast) -> VZN HOP (NYC) -> VZN (neighborhood) -> You You w/NY VPN NETFLIX(LA) -> SoCal Peering Point -> Backbone IX Host LA -> Backbone HOP (midwest) -> Backbone HOP (Northeast) -> ISP (New York) -> VPN Host -> Northeast Peering Point -> VZN IX Host Northeast -> VZN HOP (northeast) -> VZN HOP (NYC) -> VZN (neighborhood) -> You As you can see, you use precious little of the same overhead. Only your "last mile" and "the connection from NETFLIX(LA) to the peering point" is the same in all of the paths. The key "choke-points" in these examples are: "NETFLIX(LA) -> SoCal Peering Point" "SoCal Peering Point -> VZN IX Host LA" "SoCal Peering Point -> Backbone IX Host LA" Netflix argues it's got plenty of bandwidth into the peering point, and VZN doesn't want to pay to upgrade its side of the infrastructure. Verizon argues that the traffic coming from NETFLIX(LA) floods its peering point, and those upgrades are expensive, and someone needs to pay for that, and it shouldn't be them, since Netflix is making money hand over fist on Verizon's back. > If all other things are equal, the VPN network should be equal or worse than > the regular network, because the VPN is forcing an extra hop and adding > overhead both in terms of latency and payload. Completely false equality. D
