Even if I know ihnp4's capacity, how much of it am I entitled to take? I can't ask ihnp4 to assign me some fraction, since that would require n-squared messages. Is there a centralized scheme that is both fair and effective? (Read max-flow for effective.) Doesn't this require a lot of data? Incidentally, it is my understanding that the authors of pathalias had in mind an objective function that measured delay. The costs (and more importantly, their mnemonics) are an attempt, if ad hoc, to effect that goal. Peter
