NETWORK MONITORING AND DISASTER DETECTION
First Claim
1. A method of monitoring a network having a plurality of nodes, comprising:
- obtaining a status update message rate, where said status update message rate represents a rate at which status update messages are generated, where each of said status update messages comprises an information message identifying an update in a status of a network entity; and
determining from said status update message rate whether a network congestion event is occurring.

Abstract
A method of monitoring a network that includes a number of nodes interconnected by trunks has a step of obtaining processor usage data pertaining to a plurality of node processors, the processor usage data including information representative of a rate of usage of each of the plurality of node processors. The method also includes obtaining memory usage data pertaining to a plurality of memories, each of the plurality of memories associated with a node processor, the memory usage data including information representative of a rate of usage of each of the plurality of memories. The method further includes determining from the memory usage data and the processor usage data whether a network congestion event is occurring.

10. A system for determining whether a network congestion event is occurring in a network, comprising:
a processor arrangement comprising one or more connected processors, the processor arrangement operable to; obtain status update message rate, where said status update message rate represents a rate at which status update messages are generated, where each of said status update messages comprises an information message identifying an update in a status of a network entity; and determine from said status update message rate whether a network congestion event is occurring. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for use in a network comprising a plurality of nodes, where each node comprising a node processor, where each node comprising an adjacency value defined by a number of trunks connected to the node, comprising:
-
turning off at least one non-essential processor task at each node processor of a first set of nodes, wherein said first set of nodes comprise nodes running said at least one non-essential processor task, wherein said non-essential processor task comprises a task that does not prevent the node from transporting data packets; reducing the adjacency value of a second set of nodes, wherein said second set of nodes comprise nodes having high adjacencies; removing one or more entities from the network; restoring the adjacency value of the second set of nodes; and turning on the at least one non-essential processor task at each node processor of the first set of nodes. - View Dependent Claims (20)
