GVU's NSFNET Backbone Statistics Page
Covers up to April 1995


Welcome! This page (last updated May 22th, 1995) offers access to the data provided by Merit NIC Services. Both the raw data and graphs are provided. The graphs were made using Delta Graph Professional for Macintosh.

Please read the following information provided by Merit NIC Services carefully before examining the below data and graphs. Also, read this page to find current estimates of the percentage of services using each port.

NOTE: THIS IS THE LAST REPORT IN THIS SERIES. On April 30, 1995, the NSFNET Backbone Service was successfully transitioned to the new architecture, where traffic is exchanged at interconnection points called NAPs (Network Access Points.) With the end of the NSFNET project, this data will no longer be collected.


WWW as measured by Merit during April 1995 is now the largest byte and packet mover!!.
