Fine-Grain QoS Customization in Distributed Middleware Services
نویسندگان
چکیده
Quality of service (QoS) is increasingly being used to describe a broad collection of attributes, ranging from the performance-centric metrics used in the networking community to other metrics related to reliability, timeliness, and security. Moreover, QoS is also being applied to guarantees provided by a wider variety of services, ranging from communication services to higher level middleware services. In such a context, constructing a service that provides a fixed set of QoS guarantees is typically not sufficient since different applications that use the service may have very different requirements. The Cactus project is addressing these issues by providing facilities for performing fine-grain customization of QoS in distributed middleware services.

Communication services that provide enhanced Quality of Service (QoS) guarantees related to dependability and real time are important for many applications in distributed systems. This paper presents real-time dependable (RTD) channels, a communication-oriented abstraction that can be configured to meet the QoS requirements of a variety of distributed applications. This customization ability is...
متن کاملAspect-Oriented Incremental Customization of Middleware Services
As distributed applications evolve, incremental customization of middleware services is often required; these customizations should be unpluggable, modular, and efficient. This is difficult to achieve because the customizations depend on both application-specific needs and the services provided. Although middleware allows programmers to separate application-specific functionality from lower-lev...

Computing systems are increasingly distributed, real-time, and embedded (DRE) and must operate under highly unpredictable and changeable conditions. To provide predictable mission-critical quality of service (QoS) end-to-end, QoS-enabled middleware services and mechanisms have begun to emerge. However, the current generation of commercial-off-the-shelf middleware lacks adequate support for appl...
متن کاملProviding QoS Customization in Distributed Object Systems
Distributed applications are increasingly using distributed object platforms such as CORBA, DCOM, and Java RMI to standardize object interactions. With this increased use comes the increased need for providing enhanced Quality of Service (QoS) attributes related to fault tolerance, security, and timeliness. This paper describes an approach to implementing such enhancements in a transparent, hig...
