摘要： Methods, systems, and computer readable media for network test configuration using VLAN scanning are disclosed. One method for network test configuration using VLAN scanning occurs at a first port of a network equipment test device. The method includes sending a plurality of address resolution protocol (ARP) requests to a system under test (SUT), wherein each of the plurality of ARP requests includes a different virtual local area network (VLAN) identifier (ID). The method also includes receiving an ARP response from the SUT, wherein the ARP response indicates a first VLAN ID associated with the SUT. The method further includes using the first VLAN ID when sending test packets to the SUT via the first port.

摘要： Methods, systems, and computer readable media for computing label-switched data communication paths are disclosed. An example method includes receiving, by a path computation element (PCE) implemented on at least one processor, synchronization status information for routing nodes in a label-switched network. The method includes receiving, by the PCE, a request for a label-switched path (LSP) from a client. The method includes determining, by the PCE, a responsive LSP based at least in part on the synchronization status information. The method includes sending, by the PCE, an explicit route object (ERO) for the responsive LSP to the client.

摘要： Methods, systems, and computer readable media for deploying a networking test tool in a cloud computing system are disclosed. An example method includes receiving user input specifying configuration information for a networking test tool for deployment in a cloud computing system. The user input specifies a range of networking test ports. The method includes deploying a central test server in the cloud computing system and deploying one or more public test agents in the cloud computing system. The method includes configuring the central test server, the one or more public test agents, and one or more private test agents in a network outside the cloud computing system to exchange test traffic using the range of networking test ports specified by the user input. The method includes configuring a firewall for the cloud computing system to open the range of networking test ports in the firewall for the test traffic.

摘要： Methods, systems, and computer readable media for monitoring, adjusting, and utilizing latency associated with accessing distributed computing resources are disclosed. One method includes measuring a first latency associated with accessing a first computing resource located at a first site. The method further includes the measuring a second latency associated with accessing a second computing resource located at a second site different from the first site. The method further includes selectively impairing transmission of packets to or processing of packets by at least one of the first and second computing resources in accordance with a performance, network security, or diagnostic goal.

摘要： A method for testing network route convergence includes receiving input for specifying a route convergence threshold and a frame loss tolerance for a route convergence test. The route convergence test is initiated by transmitting data plane traffic addressed to at least one destination to a device under test (DUT). At least one route is advertised to the DUT. A first time instance when the at least one route is advertised to the DUT is recorded. Data plane traffic routed by the DUT is monitored. It is detected when data plane traffic for the at least one route reaches the route convergence threshold. In response to detecting that the data plane traffic reaches the route convergence threshold, a second time instance is recorded and a route convergence validation test phase is initiated. During the route convergence validation test phase, an indication of frame loss for the at least one route is determined and an indication of validity or invalidity of the route convergence test is generated based on a relationship between the indication of frame loss and the frame loss tolerance.

摘要： Methods, systems, and computer readable media for benchmark reference testing of data center or network equipment are disclosed. One method includes, using a network or data center test device, executing a plurality of performance tests to test a plurality of different performance parameters of a network or data center device under test. The method further includes obtaining individual test results for each of the different performance parameters. The method further includes generating a multi-dimensional score that combines the individual test results from the different performance parameters to indicate a composite performance of the data center or network device. The method further includes outputting the multi-dimensional score to a user.

摘要： Methods, systems, and computer readable media for utilizing predetermined encryption keys in a test simulation environment are disclosed. In one embodiment, a method includes generating, prior to an initiation of an Internet protocol security (IPsec) test session, a private key and a public key at a traffic emulation device and storing the private key and the public key in a local storage associated with the traffic emulation device. The method further includes retrieving, from the local storage, the private key and the public key upon the initiation of the IPsec test session between the traffic emulation device and a device under test (DUT) and generating a shared secret key utilizing the retrieved private key and a DUT public key received from the DUT.

摘要： A test system includes a radio frequency (RF) shielded chamber and an antenna array in the RF shielded chamber. The antenna array includes groups of antenna elements and power combiners. Each group of antenna elements is matched to a matching group of antenna elements by virtue of being coupled to a respective power combiner for both the group and the matching group. The antenna array is configured, by virtue of spacing apart the antenna elements by at least half of a wavelength of a test signal for testing a wireless device in the RF chamber, so that power delivered to output ports of the antenna array is substantially uniform regardless of where the wireless device is placed within the RF chamber.
