                     Traffic Statistics (July 1972)

   For several months BBN has been supplying ARPA with a monthly summary
   of "Host packets output."  In response to questions from several
   sites, ARPA has agreed to allow us to publish these statistics in RFC
   form also.  Attached are the traffic statistics for the month of July
   1972.

   Please note that the numbers given are either monthly totals or
   overall averages (i.e., based on 24 hours per day, seven days a
   week).  Thus, these numbers are not useful in determining peak
   traffic conditions.
