Say a node operator's single node is using up 50% of currently pending requests, so that FractionOfCurrentlyPendingRequestsFromThisNode=50%. Also, suppose Current%OfOverload=80%. Under my plan, I would reject 50%*80%=40% of incoming requests from that node. Now, say the node operator gets greedy, and wants to reduce the number of queries rejected. He routes to 50 separate nodes in his routing table, and has each query 1/50th of the original node. Because his traffic is no longer on that node (98% of it anyway) the node goes from 180% of what it could handle to 91.8% of what it can handle. Now, each node will have on average the same load. So FractionOfCurrentlyPendingRequestsFromThisNode=1%, and you will reject 1%*0%=0% of incoming requests from each of the 50 nodes. Which means that I will reject 0% of incoming requests from ALL 50 nodes. Which means that the greedy node operator has beaten YOUR system. I am done arguing over this. If you still can't comprehend this then you go make your SuperLeachFreenet, and people will laugh when it is easily beatout in any benchmark just by upping the MAXnumber of nodes in the routing table in the config file. _______________________________________________ Devl mailing list [EMAIL PROTECTED] http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/devl
