Abstract:
1. A method of pseudo-random testing a fault tolerant network to determine the network's response to a failure, comprising: (a) storing an image of a network on a host, including the network's components and interconnections; (b) selecting at least one part of the network to physically fail using a pseudo-random number generator whereby said selection is done pseudo-randomly; (c) failing the at least one selected part of the network, detecting the network's response to the failure, and logging all attempts to repair the failure, up to and including the first successful attempt to repair the failure; (d) repeating steps (b) and (c) for each possible network failure, and said step (c) further comprising logging all attempts to repair each failure, up to and including the first successful attempt to repair the failure for each failure; and (e) for a failed test, restarting the test at the point the test failed, whereby the test need not be restarted at the beginning of the number sequence once a repair is made.
