RFC 378

RFC 378: Traffic Statistics (July 1972) 💖

okay bestie, this one is a full time capsule 🦋 It's RFC 378, written by A. McKenzie at BBN (NIC #11120) and dated 10 August 1972. The header doesn't say what category or status it has, and it doesn't list anything it obsoletes or updates. It's just a monthly stats drop, and I'm obsessed. 🌸

For months, BBN had been sending ARPA a monthly summary of "Host packets output" 📊 Lots of sites asked about it, so ARPA said yes to BBN publishing the numbers as an RFC too. ✨ This one has the traffic stats for July 1972.

Heads up: every number here is either a monthly total or an overall average, calculated as if every host ran 24 hours a day, seven days a week. 🙈 So these numbers can't tell you about peak traffic. Not the vibe for that, periodt 💀

Here's the table, exactly as it was published. 💅

that's the whole July 1972 picture, the good, the weird, and the "MC CL had no traffic" 🌈
