§1What the Report Is
RFC 566, from A. McKenzie of BBN-NET and dated 4 September 1973, is a cover note: "Attached are the Hosts traffic statistics for the month of August 1973." The header says it updates RFC 556.
The rest is the attached table, titled HOST THROUGHPUT SUMMARY (PACKETS OUTPUT).
A person at BBN sent around a monthly scoreboard of network traffic.
§2How to Read the Table
Each row is a host at a site such as UCLA, SRI or MIT. For each host the table gives internode packets, intranode packets and a total. Sites with several hosts also get a subtotal, the average daily internode packets, and the number of days counted, which is 31 for August.
BELV, ABER and LBL are listed as having had no traffic.
Each line says how many messages a computer sent to other places and how many it kept close to home.
§3Network Totals
The network-wide totals are 99009940 internode packets and 37732470 intranode packets. The daily averages are 3193869 and 1217177, and the average per node-day is 86321 and 31897.
PACKETS/MESSAGES (INTERNODE) is again 1.07. Among the listed hosts, ISI HOST 1 had the most internode packets, 14683780.
The bottom adds everything up so you can see how busy the whole network was that month.
