Abstract Distributed applications are difficult to build and main - tain and are even more difficult when the applications are distributed over wide - area networks Distributed Object Computing middleware has emerged to simplify the building of distributed applications by hiding implemen - tation details behind functional interfaces However, critical applications have non - functional requirements, such as real - time performance, dependability, or security, that are as important as the functional requirements, but are also hidden by the middleware Because current dis - tributed object middleware doesn't support these aspects of critical applications, application developers often find themselves bypassing the distributed object systems, ef - fectively gaining little or no advantage from the middle - ware We have developed Quality Objects (QuO), a framework for including Quality of Service (QoS) in dis - tributed object applications QuO supports the specifica - tion of QoS contracts between clients and service provid - ers, runtime monitoring of contracts, and adaptation to changing system conditions A crucial aspect of QuO is a suite of Quality Description Languages for describing states of QoS, system elements that need to be monitored to measure the current QoS, and notification and adapta - tion to trigger when the state of QoS in the system changes This paper gives a brief overview of QuO and describes the syntax and semantics of CDL, the compo - nent of QDL for describing QoS contracts |
