Publication number: 20240267314Abstract: According to examples, an apparatus may include a hardware processor that may determine throughputs at which servers communicated over a network through execution of throughput tests with the servers. The hardware processor may also identify which of the servers communicated over the network at a throughput that meets or exceeds a predefined throughput and may send identifiers of the servers to a test service provider. The test service provider may, in response to receipt of a request for execution of a throughput test that meets or exceeds the predefined throughput, at least one of output an identifier of at least one of the identified servers to execute the throughput test and select one of the identified servers to execute the throughput test. The hardware processor may also cause a test instrument to execute a throughput test with the identified server at or above the predefined throughput.Type: ApplicationFiled: February 8, 2023Publication date: August 8, 2024Applicant: VIAVI SOLUTIONS INC.Inventors: Hans-Joerg WOLF, Reynald DUPUIS, Jay Sovick LESTER, Gregory Scott TOPMILLER, Ying PAN

Patent number: 12009871Abstract: Disclosed are a test instrument and testing methods for audibly providing signal metrics (such as signal strength and/or signal quality) of fifth-generation network (5G) beams to assist installation of 5G Customer Premises Equipment (CPE) antenna at a premises. A test instrument may obtain signal metrics and provide audio output based on the signal metrics at various locations of the premises. The audio output may be transmitted to a headphone device worn by a user or a speaker. In this manner, the user may select an appropriate location on the premises at which to install the 5G CPE antenna via audible queues that are based on the measured signal metric at a given location. The test instrument may provide fine-tuning capabilities by also audibly providing directional information that indicates where the 5G CPE antenna should be pointed or moved to align the 5G CPE antenna to a 5G beam.Type: GrantFiled: January 18, 2023Date of Patent: June 11, 2024Assignee: VIAVI SOLUTIONS INC.Inventors: Scott Roy Pettygrove, Hans Joerg Wolf, Karthik Subramanian

Patent number: 11943130Abstract: In some examples, aggregation-based speed testing may include ascertaining, by a test speed analyzer, a test speed that corresponds to a maximum specified data transfer rate for a data transmission link. A test range generator may determine a maximum specified port speed of a test port of a device connected to the data transmission link. The test range generator may determine whether the maximum specified port speed is less than the test speed, and if so, divide the test speed into a plurality of test ranges. A total value of the test ranges may be equal to the test speed. A test performer may perform tests corresponding to the test ranges, and obtain intermediate test results. A test result generator may generate, based on aggregation of the intermediate test results, an aggregated test result that represents an actual speed associated with the data transmission link.Type: GrantFiled: October 6, 2022Date of Patent: March 26, 2024Assignee: VIAVI SOLUTIONS INC.Inventors: Karthik Subramanian, Reynald Dupuis, Hans Joerg Wolf

Patent number: 11910136Abstract: Disclosed are apparatuses and testing methods for emulating an Optical Network Terminal (ONT) device for communicating or otherwise working with an Optical Line Terminal (OLT) device that was configured to operate with the ONT device. Such emulation may include configuring various settings of the apparatus so that the apparatus may appear to the OLT to be the ONT device. For example, the emulation may include accessing and using authentication/authorization related settings and network configuration settings of the ONT, thus permitting the apparatus to connect to a Passive Optical Network and test services and the quality of service experience without having to reconfigure the OLT.Type: GrantFiled: August 17, 2022Date of Patent: February 20, 2024Assignee: VIAVI SOLUTIONS INC.Inventors: Hans Joerg Wolf, Reynald Dupuis

Patent number: 11876698Abstract: In some examples, high-speed hardware-based traffic analyzer integration with speed test control application may include receiving, from a speed test control application, speed test control instructions and data connection instructions to perform an upload and download high-speed test associated with network traffic for a network. The speed test control instructions and the data connection instructions may be forwarded to a speed test control server. A hardware-based traffic analyzer may perform, based on the speed test control instructions and the data connection instructions, the high-speed test associated with the network traffic for the network.Type: GrantFiled: April 21, 2022Date of Patent: January 16, 2024Assignee: VIAVI SOLUTIONS INC.Inventors: Hans-Joerg Wolf, Jyotikumar Menon, Anand Gajjala

Publication number: 20230370164Abstract: Disclosed are an apparatus and testing methods for performing testing operations over multiple types of links and through multiple potential points of failure to segment sources of problems, which may relate to reported or actual instances of service disruption in a network communication environment. The apparatus may perform service layer testing directly via an optical link, in addition to via Ethernet service layer testing. The apparatus may further conduct tests on other layers as well, including the physical layer, the network layer, and the link layer. To facilitate efficient testing, the apparatus may integrate programmable workflow profiles that specify tests to be conducted, and may interface with a cloud platform for sharing results of the tests, providing end-to-end testing of various components and types of links (whether optical or electrical, including wired and wireless links). Results of the tests may provide guidance to resolve detected problems.Type: ApplicationFiled: April 17, 2023Publication date: November 16, 2023Applicant: VIAVI SOLUTIONS INC.Inventors: Hans Joerg WOLF, Reynald DUPUIS
