AI Technical Summary

Benefits of technology

Early detection and intervention using processor and memory usage data, along with status update message rates, effectively mitigate control message storms, preventing network congestion and failure.

Problems solved by technology

In particular, it has been observed that node processor usage and node memory usage spike during control message storms.

Embodiment Construction

[0032]FIG. 1 shows a network area 100 in which the present invention may be implemented. The network area 100 may be one of several network peer groups or areas in a multi-layer network. For purposes of clarity of exposition, the network peer group or area 100 will be referred to generally herein as simply the network 100. The network 100 may suitably be an ATM network, IP network, or other network that employs link-state routing protocols such as PNNI or OSPF, among others. In the exemplary embodiment described herein, the network 100 is described as an ATM network that employs PNNI. However, it will be appreciated that the operations described herein apply to a broad range of networks using a broad range of link state routing protocols.

[0033]Referring specifically to FIG. 1, the network 100 includes a plurality of nodes 102, 104, 106, 108, 110, 112, 114, 116, 118, 120 and 122, which are interconnected by a number of links or trunks 202, 204a, 204b, 206, 208, 210, 212a, 212b, 212c,...

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.

Description

[0001]This application is a continuation of co-pending U.S. patent application Ser. No. 10 / 336,471, filed Jan. 3, 2003, entitled, “NETWORK MONITORING AND DISASTER DETECTION”, which has been allowed, and is herein incorporated by reference.[0002]Cross-reference is made to co-pending application Atty. Docket No. 2001-0566 entitled “NETWORK SEGMENTATION METHOD”, filed on Jan. 3, 2003, which has issued as U.S. Pat. No. 7,283,484.FIELD OF THE INVENTION[0003]The present invention relates generally to the field of communication networks, and more particularly, to monitoring and disaster detection in communication networks.BACKGROUND OF THE INVENTION[0004]One common form of digital communication network is a network that employs a link-state routing protocol. Asynchronous transfer mode (“ATM”) networks and Internet protocol (“IP”) networks are well-known examples of networks that employ link-state routing protocols. While a large class of link state routing protocols exist, common examples ...
