Define Internet Backbone.

The internet "backbone" refers to the top level internet providers who own huge "nodes" on the internet and transmit billions of transactions across their network, interconnecting to other "backbone" nodes. Some of them are universities.  This has grown from an original seven locations to multiple locations, most of which are now private providers such as Level 3, MCI UUNet, NTT Verio, PAIX, WilTel, etc.
