March 1991, NSFNET traffic is now measured as the total packets for T1 and T3 networks. May 1992, is an estimated value; actual value is unavailable. December 1992, all traffic is on the T3 network; the T1 has been retired. December 1994, numbers begin decreasing as traffic migrates to the new NSF architecture, for which no comparable statistics are available. April 30, 1995, the NSFNET Backbone Service successfully transitions to the new NAP architecture. The end of the NSFNET project marks the end of collection of this data.
