NSFNET was a series of networks coordinated by NFS, created to serve research and education purposes. Based on ARPANET protocols, NFSNET served as the backbone of a growing internet up until April 1995. The role of the backbone has since been handed over to several commercial carriers, dissolving the notion of a single national Internet backbone.
