    Abstract

    The current generation of distributed and automated physical location surveillance systems faces high demands for robustness and reliability. We present and evaluate the design of the Logical Decision Making Server (LDMS), a rule-based automated decision making component used in the Single Location Surveillance Point (SLSP) system. To validate the robustness of the LDMS design for operation in the SLSP environment, we design and conduct a stress test experiment in which large load of TCP/IP input messages is sent instantaneously to the LDMS prototype implementation using the Nethawk EAST software. The stress test results are compared to measurements obtained during a real-life scenario. The LDMS is observed to withstand a significant amount of load without crashing, and its performance is can be considered sufficient for the SLSP system needs. A detailed analysis of results however shows an increase in the latency resulting from an extreme temporal load. We identify potential areas in the design to be improved if demands for higher response rates arise. The research is based on the construction of the related publications and technologies, and the results are established from the testing and validation of the implemented LDMS within the SLSP system.
