Mark, Thank you for your message: >... how does the end host figure out which situation (congestion > or outage) it is in? There are two end hosts. Only one of them has a good chance of knowing, and the other doesn't usually care these days. I agree that a well-designed signaling method (whether by TCP extensions or ICMP extensions) is a good idea, and I am sure that will be better-used in the future. For now, though, in the situation most nets are in, if people want services that can be accessed reliably by wireless communications, they might want to at least lower their TCP maximum retransmition timeout values, consider lowering their RTO maximum, read Reiner's comments on the DoCoMo draft: http://pilc.grc.nasa.gov/pilc/list/archive/0996.html and have a look at his TCP-Eifel page: http://iceberg.cs.berkeley.edu/downloads/tcp-eifel Now, I wonder which cellphone will be the first to play MIME audio/mpeg attachments AND have PPP available on a DB-9 RS-232. Cheers, James
