Distributed Resource Management to Support Distributed Application-Specific Quality of Service
نویسندگان
چکیده
This paper presents a policy-based software architecture and implementation for application Quality of Service (QoS) management. The approach is dynamic in that the application is started with an initial resource allocation, and if it does not meet its QoS requirement, a resource manager attempts to allocate more resources to it until its QoS requirement is met. One key problem is that of determining the corrective action(s) to be taken when an application’s QoS requirements are not being satisfied. For example, one possible action is to adjust the application’s CPU priority when its QoS requirement is not being met. However, if there are several applications on the same host with QoS requirements, this may not be feasible. In other words, there may be constraints on the corrective actions depending on other factors. This paper explores the use of administrative policies to guide decisions on actions to take to meet QoS requirements and presents a prototype and initial experimentation.

Experimentation with Event-Based Methods of Adaptive Quality of Service Management
Many complex distributed applications require quality of service (QoS) guarantees on the end-to-end transfer of information across a distributed system. A major problem faced by any system, or infrastructure, providing QoS guarantees to such applications is that resource requirements and availability may change at run-time. Consequently, adaptive resource (and, hence, service) management mechan...

Grid computing provides a robust paradigm for aggregating disparate resources in a secure and controlled environment. The emerging grid infrastructure gives rise to a class of scientific applications and services in support of collaborative and distributed resource-sharing requirements, as part of teleimmersion, visualization and simulation services. Because such applications operate in a colla...

A fundamental problem with distributed applications is to map activities such as computation or data transfer onto a set of resources that will meet the application’s requirement for performance, cost, security, or other quality of service metrics. An application or client must engage in a multi-phase negotiation process with resource managers, as it discovers, reserves, acquires, configures, m...
