ABSTRACT:
A network failure simulation tool provides simulation of a network failure suitable for automated software testing under software control. The tool intercepts packets being sent or received by a computer on a network by redirecting the packets from a network I/O architecture to substitute packet handlers. The tool also resumes normal network operation by again directing packets through actual packet handlers of the computer's network I/O architecture. Commands are provided for controlling suspension and resumption of network operation by the tool from an automated software testing program.
