I can't find "jran" in either freenet email or on IRC today. Smaller tables are a problem when most of the nodes in them are backed off. With a big table, you are more likely to have overlaps so that you can use a different "server." (Prompt notification of the overload is important to avoid corrupting the estimator -- just letting it time out is not a good idea). So when several servers are insignificantly different in qualification, choose randomly among them, get prompt notification of overload, and try another without penalty. Better, already know which are overloaded and don't even waste time sending a query. This requires large RT so that several redundant servers are available for each area of keyspace. > > > be possible to run with a huge routing table.

We have to guess what might work, and try it, hoping to shake bugs out in the process. (I don't see that using larger RT's would require rearrangement of data). -- Ed Huff _______________________________________________ Devl mailing list [EMAIL PROTECTED] http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/devl
