Quality of Service Behavioral Model from Event Trace Analysis

Abstract

The distributed command & control environment includes limited computer resources and numerous mission critical applications competing for these scarce resources. Additionally the stringent constraints and considerable complexity of distributed command & control systems can create a condition that places extreme demands upon the allocated resources and invites a potential for program errors. Consistent quality of service distribution can be a critical element in ensuring effective overall program completion while avoiding potential errors and process failures. The potential for errors and process failures can be understood and addressed by performing a practical analysis of the resource deployment procedures utilized within this environment. However, analyzing resource-based quality of service within a distributed command & control environment is a demanding endeavor. This difficult task can be simplified by directly examining specific quality of service actions that take place during program execution. Therefore, topragmatically isolate these actions and develop a practical quality of service behavioral model, the research discussed in this paper has implemented an event trace approach to examine the exact quality of service execution path during program operation.
