System and method for automatic identification of bottlenecks in a network

摘要

A system and method for providing automated bottleneck identification in networks and networked application environments by processing using end-to-end quality of service measurements in combination with knowledge of internal resource dependency information generated by a network administrator. In one aspect, a method for identifying bottleneck resources in a network having a plurality of resources comprises the steps of: specifying a plurality of probe transactions in the network; generating resource dependency information representing dependent resources for each of the probe transactions; executing the probe transactions; measuring end-to-end quality of service data resulting from the executing of the probe transactions; and processing the resource dependency information and measured end-to-end quality of service data to identify bottleneck resources in the network. The system and method eliminate the need for obtaining and processing detailed measurements and/or estimates of parameters or data at the per resource level to identify bottlenecks.
