Management system and method for monitoring stress in a network

摘要

A system and method for providing a stress value representing the performance of a network comprising network devices is described. A raw data value for a monitored characteristic of a network device or link is obtained by the management system and compared with a predetermined threshold value for the monitored characteristic. If the raw data value is greater than or equal to said threshold value, the management system provides a stress value equal to a default value, said default value being a maximum or minimum value of a predefined bounded range; and if the raw value is less than said threshold value, the management system calculates a stress value within said predefined bounded range using an appropriate algorithm for said monitored characteristic.
