Fault isolation in large networks
First Claim
1. A computer accessible medium comprising 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 one or more faults, wherein nodes are probed in a sequence; and
in response to receiving a first alert transmitted by a first node in the network, wherein the first node is configured to transmit the first alert in response to the first node detecting an event and independent of the probes performed according to the sequence and asynchronous to the probes performed according to the sequence, probe one or more neighbor nodes of the first node.

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.

- 7. A computer system comprising a probe agent and an inspector, wherein the probe agent is configured to probe nodes in a network in a sequence to determine if the nodes are experiencing an event or events indicative of one or more faults, and wherein the inspector is configured, in response to receiving a first alert transmitted by a first node in the network asynchronous to the probing by the probe agent, to identify one or more neighbor nodes of the first node and to cause the probe agent to probe the one or more neighbor nodes independent of the sequence.

12. A method comprising:
-
probing nodes in a network to determine if one or more nodes are experiencing one or more events indicative of one or more faults, wherein nodes are probed in a predetermined sequence; receiving a first alert transmitted by a first node in the network asynchronous to the probing and independent of the probing, wherein the first node is configured to transmit the first alert in response to the first node detecting an event and independent of the probes performed according to the sequence; and in response to receiving the first alert, probing one or more neighbor nodes of the first node. - View Dependent Claims (13, 14)
