Abstract : This report documents an in-house program to test and evaluate the Fault Detection and Isolation Algorithm developed. Testing of the fault isolation capability required extensive use of the accompanying emulation facility. Several network connectivities were simulated. These included a Highly Interconnected Network, Dumbell Structured Network, Loop Network and a Backhauling Network. To test the performance of the algorithm on these networks, several different fault scenarios were designed for each network. Each scenario would take advantage of the connectivity particular to each network. The results of the testing show that the algorithm is able to correctly identify the location of a fault to the equipment level under a wide range of conditions. It is noted, however, that the time required to find these faults varies considerably with network connectivity. Based upon the test results detailed in this report, it is recommended that although the algorithm should be kept functionally the same, it should be rewritten to correct various deficiencies (such as execution time varying greatly with connectivity).
