This was especially important for dial-up links. (NetBlazer, Lan'sEnd, etc., none of which are in much use today.) I have also _set_ the low delay bit for telnet traffic on those boxen, but you don't telnet out of routers very often. I'd have to check the source, but I'm pretty sure I put at least some of that stuff in Qualcomm/Sony cell phones and base stations, so it might still be in use today. I have also used the TOS bits in a weighted fair queuing scheme. I never figured out how "high reliability" would be implemented. I just tried to never have low reliability. :-) WSimpson@UMich.edu Key fingerprint = 17 40 5E 67 15 6F 31 26 DD 0D B9 9B 6A 15 2C 32
