So, I've actually studied this in real-world conditions and TCP behaves exactly as I described in my previous email for exactly the reasons I explained. If you think it doesn't, you don't know what you're talking about. Window scaling and SACK makes it possible for TCP to grow to consume the entire whole end-to-end pipe when the pipe is at least as large as the originating interface and -empty- of other traffic. Those conditions are rarely found in the real world. Regards, Bill Herrin -- William Herrin b...@herrin.us https://bill.herrin.us/
