SubjectRe: using TOS as a key in route cache
Hello
Thanks for your reply. But this can create problems
in some of the cases. For example, "scp" over TCP
starts with TOS 0, then goes to 8 (bulk data). What
happens is that when RTOs are cached, they are
updated for TOS 8 and not for TOS 0, therefore a
new connection does not pick up the cached RTO.

Does this make sense ?

Thanks,
