Just browsing through my routing table status servlet and noticed something worrying - a backed-off node whose last estimate was -27143ms. Presumably we shouldn't be getting negative estimates for routing times.


Hmmm, just found another 6 of them in my RT - it looks like this is actually quite common. BTW I am running 6338.

Ian.

I think the reason is:


estimate=(pDNF - pLegitDNF) * (tDNF + requestFailTime)
          + pSuccess * tSuccess
          + pTransferFailed * (tTransferFailed + requestFailTime)

and in the negative cases, pDNF<pLegitDNF.

I notice that for many of the ones with negative estimates, overall prob of DNF is "0".
