I keep seeing servers saying that they have an OC-x (fill in the x with a number). Where are they getting this type of connection? I've researched a little bit, and it looks expensive as hell. Thanks for your help.
OC-x(s) usually are only backbones the ISP is running. Most major ISPs have that, just have to search around. Like my ISP, they have OC-48 and OC-192 backbones. The switch is a gigabit switch connection, each port is only allocation to 100mbit full-duplex.
