Aspect-Oriented Management of Service Requests for Assurance of High Performance and Dependability

A new approach to service requests management in case of insufficient hardware resources is proposed. It is based on wide aspects of requests analysis and it assures reliable and fast access to priority services. Requests are analyzed for, among others, time of occurrence, category of user who made the request, type of service, current system load and hardware utilization. Deterministic but dynamic rules help to manage system load very effectively, especially in terms of dependability and reliability. The proposed solution was tested on Gdansk University of Technology central system, followed by the discussion of the results.
