Explicitly rejected by the ISPs at the beginning of diffserv.

As has been said (*everything* has been said several times over the last year), it's too late to change AH. In any case, it doesn't matter: if people change a QOS field to request better service, they will get it and pay for it; no problem there. (Theft of service, or DoS by injecting bogus QOS traffic, is taken care of by admission control at the network edge; nothing we are discussing here changes that.) > But this is perhaps the topic for another > thread and maybe another working group... This is old news to the QOS-related WGs.
