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.
摘要:
A method for fetching sparsely indexed MIB tables for a managed network device using an approximation operation, such as a GetNext SNMP operation, comprises sending a plurality of operations in a first data packet at least one of the plurality of approximation operations specifying a speculative approximation. By using speculative approximations of index values of data to be fetched, it is possible to retrieve MIB table data more quickly and efficiently.
