Non-disruptive integrated network infrastructure testing
View Patent ↗Non-disruptive integrated testing of network infrastructure in which one or more processors of a first network interface device (NID) performs tests on a network cable connected to a first NID of a host system, and connected to a second NID. Tests verify connectivity of the cable, a bandwidth capacity baseline, and a maximum bandwidth of the network cable. A self-test determines the host operating system, host status, and operational status of the host NID, and responsive to changed conditions, NID settings are reverted to a pre-validated condition state, and confirmation of reverting is sent to the host. Network activity is suspended if received by the host ID during scheduled network cable tests. Upon completion of tests and storing of test results in NID memory network activity resumes. Results of the tests are transferred from memory of the first NID to persistent storage of the host system.
1. A computer program product for non-disruptive integrated testing of network infrastructure, the computer program product comprising:
one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
program instructions for a first network interface device to perform a set of tests on a network cable of a network infrastructure, wherein a first end of the network cable is connected to the first network interface device of a host system by a first cable connector, and a second end of the network cable is connected to a second network interface device by a second cable connector, and wherein the set of tests includes connectivity verification of the first end and the second end of the network cable, a bandwidth capacity baseline measurement of the network cable, and a maximum bandwidth measurement of the network cable;
wherein testing includes one or more processors performing initiation of the set of tests during a period of time in which the network activity over the cable is idle; and suspending the set of tests in the event of detecting network activity associated with said cable; and yields priority to the communication transmissions over the cable until said network activity is idle; subsequent to the completion of said detected network activity, sending instructions to the processor to resume the set of tests on said cable;
program instructions to perform a self-test in which a determination of a host operating system, host status, and an operational status of the network interface device, are performed, and in response to the self-test resulting in changed conditions, reverting settings of the network interface device to a previously validated condition state, and confirm reverting of the settings by sending a confirmation alert to the host computing device, and retain a record of reverting settings for review;
program instructions to suspend network activity which is received by the first network device of the host system, in response to initiating a set of tests on the network cable that are scheduled to be performed;
program instructions to resume network activity which is suspended, in response to completion of the set of tests;
program instructions to store results of the set of tests in a memory of the first network interface device; and
program instructions to transmit the results of the set of tests from the memory of the first network interface device, to persistent storage of the host system.
