QUALITY OF SERVICE (QOS) MANAGEMENT FOR MESSAGE FLOWS ACROSS MULTIPLE MIDDLEWARE ENVIRONMENTS

摘要

A method of managing information system resources to provide a message flow having a consistent level of quality of service "QoS" within and across a plurality of interconnected middleware domains includes receiving a QoS message from a first QoS manager (426, 564) expressing at least one QoS requirement, translating the at least one QoS requirement to at least one parameter specific to a messaging service (432) that communicatively couples multiple middleware domains (404, 406), creating a client connection between a first middleware domain (404) and the messaging service for receiving the message flow, transmitting the QoS message to a second middleware domain (406), and creating a client connection between the messaging service and the second middleware domain for transmitting the message flow.
