ABSTRACT:
In some embodiments, a computer accessible medium comprises a plurality of instructions which, when executed, probe nodes in a network to determine if one or more nodes are experiencing any events indicative of a fault. The nodes are probed in a sequence. The instructions, when executed, in response to receiving a first alert transmitted by a first node in the network asynchronous to the probes performed according to the sequence, probe one or more neighbor nodes of the first node. In some other embodiments, the instructions, when executed, in response to receiving a first alert transmitted by a first node in the network asynchronous to the probes performed according to the sequence, interrupt probing according to the sequence to probe at least the first node.
