The Traffic Data Management System (TDMS) is a product of Lucent Tech- nologies designed to satisfy the growing need for a single traffic data collection and analysis system for an entire telecommunications network. TDMS consists of one or more Data Analysis Processors (DAP) and Data Collection Processors (DCP). The TDMS Engineering Guidelines are a set of rules to plan and maintain the config- uration of the TDMS network. The current version of the Engineering Guidelines was created in 1994. This thesis describes the reason and the process to redefine TDMS DAP Engineering Guidelines and to improve the performance of TDMS. It investigates and analyzes the current TDMS network status and DAP configurations at Bell South Telephone Company, calculates and changes many DAP configuration parameters according to the data collected, and tests the changes in the field. This thesis also suggests the addition of certain execution time recording function calls at the end of TDMS processes, which would lower the usage of resource required by the system monitoring tools, and to add an on-line capability of performing the calcu- lations contained in the TDMS DAP Engineering Guidelines, which would make it more convenient and timely for TDMS administrators to make decisions on system load balancing.
