Quality of Service (QoS) management in a service-based system may be provided by adaptively adjusting system operational parameters in response to real time relationships between QoS specifications and measurements. A QoS manager may include a measurement engine configured to acquire real time data that is specific to transaction instances of various transaction types. The manager also may include a controller for comparing transaction data from the measurement engine to the guaranteed QoS standards. Depending upon the results of the comparison, the controller may invoke control actions.

System and method of monitoring e-service Quality of Service at a transaction level

The management of end-to-end cooperation among multiple e-service providers is enabled in a distributed correlation manner by locally appending a tag to each outgoing document, with each tag uniquely identifying the transaction to which it is related and identifying management information. The tags are management information structures that are updated at each participating e-service provider. Consequently, in a succession of e-service providers, the parent e-service is furnished with management information for each of the participating e-services and is able to discern the contributions of each such e-service. The different providers maintain separate management information libraries which are used in registration and correlation processes.
