Abstract: Methods, systems, and computer readable media for processing QUIC communications in a network. An example system includes a first network interface for receiving a QUIC connection request from a first node in the network and, in response, establishing a first QUIC connection between the first node and the system. The system includes a QUIC processing module configured for receiving, via the first QUIC connection, encrypted QUIC data including a number of streams and decrypting the encrypted QUIC data, resulting in decrypted QUIC data. The QUIC processing module is configured for extracting each of the streams from the decrypted QUIC data, resulting in a plurality of extracted streams, and packaging at least one of the extracted streams into a non-QUIC protocol format, resulting in at least one packaged stream. The system includes a second network interface for transmitting the packaged stream to a second node in the network.

Abstract: Methods, systems, and computer readable media for measuring data integrity in time sensitive networks. An example method for testing a time sensitive network (TSN) device includes calculating a data integrity value for a preemptable frame. The method includes appending the data integrity value to an end of the preemptable frame and transmitting the preemptable frame to the TSN device, causing the TSN device to fragment the preemptable frame or to reassemble the preemptable frame after fragmentation. The method includes receiving the preemptable frame after traversing the TSN device and validating the data integrity value of the preemptable frame after traversing the TSN device.

Abstract: A method for injecting a test plugin into a user-space network protocol stack executing on a device under test (DUT) and executing the test plugin during testing of the DUT includes transmitting, from a test system and to a first DUT, a first test plugin. The method further includes injecting the first test plugin into a user-space network protocol stack executing on the first DUT while the user-space network protocol stack is executing. The method further includes executing the first test plugin. The method further includes, while the first test plugin is executing, transmitting test packets to the DUT and receiving packets from the DUT. The method further includes reporting, from the DUT and to the test system, results generated from execution of the first test plugin.

Abstract: An instrument for measuring a physical quantity, an instrument system having a plurality of such instruments, and a method for operating such a system are described. The instrument includes a sensor, an instrument class error calculator and a communication interface. The sensor measures the physical quantity and generates a value, Vm, for the physical quantity. The instrument class error calculator provides an instrument class error associated with Vm. The instrument system includes a plurality of these instruments that are manufactured on an ongoing basis. The instrument system includes a database that stores a measurement generated by each instrument in a sample of the instruments during manufacture and a communication link between the database and one of the instruments in the class that provides information on the instruments based on measurements made after the one of the instruments in the class was manufactured.

Abstract: In some examples, a system includes a test controller and a training data collector. The test controller is configured for receiving a test case including test case definition information defining a network test for a system under test (SUT); determining test system resource information for test system resources configured to execute the test case; and executing the test case on the SUT. The training data collector is configured for collecting at least a portion of the test case definition information; collecting SUT status information or SUT configuration information or both for the SUT; collecting metadata associated with the test case including at least one test context label; and processing collected data to produce artificial intelligence training data.
