Right.  Perhaps the lesson from Vijay is if you're building your own
fibre network and you have billions of dollars of capital, you should
just build point-to-point everywhere you need (over DWDM via 10G LAN
PHY) and stick high capacity Ethernet routers (with big buffers, such
as the Arista stuff) to do your "drops", since that SoNET stuff is for
dinosaurs. :-).

Less sarcastically, network scaling goes well beyond equipment choice
and volume - it's more about how you deploy, track, manage and
visualise the network.  His employer has a team doing great work here.
