Abstract
In a network, a set of machines communicate pairwise, each conditionally adjusting messages in response to its own local state, and each in response to statistical methods conditionally propagating those messages, with the effect that problems with that network, or with a subset of its machines, are reported to a receiver/server. Only a substantially constant number of reports are made to the receiver/server, even when there are a substantial number of such machines able to detect that problem. When a problem is reported, a similar technique causes the machines to collectively evaluate and report suggested causes for that problem. Messages are propagated from each machine to another using locally random global locality. The machines in the network, in response to statistical techniques, organize hierarchically in O(log n) time, where n is the number of machines in the network, substantially without any requirement for nonlocal message exchange.
