NSFNET performance statistics have been collected, processed, stored, and reported by the Merit Network since 1988, in the early stages of the NSFNET project. During December 1994, the numbers contained in Merit's statistical reports began to decrease, as NSFNET traffic began to migrate to the new NSF network architecture. In the new architecture, traffic is exchanged at interconnection points called NAPs (Network Access Points.)

The reports will be discontinued by spring 1995. -Susan Horvath Merit NIC Services
