During operation, the system obtains a set of metrics related to a performance of a single-page application (SPA), wherein the set of metrics includes an initial page load time of the SPA that is calculated from a page load event and a render completion time and a subsequent page load time of the SPA that is calculated from a transition time and the render completion time. Next, the system uses the set of metrics to display a graphical user interface (GUI) comprising a chart of a performance of the SPA. The system then displays, in the chart, a representation of the page load time for the SPA.Type: ApplicationFiled: February 16, 2016Publication date: August 17, 2017Applicant: LinkedIn CorporationInventors: Sreedhar Babu Veeravalli, David Q.

Publication number: 20170237638Abstract: The subject matter described herein relates to methods, systems, and computer readable media for test system connection resiliency. In some examples, a method for testing a network device under test (DUT) includes exchanging a sequence of data packages over a transmission control protocol (TCP) connection between a client and a server and through the network DUT. The method includes storing client sequence identifiers and server sequence identifiers. The method includes synchronizing, in response to detecting an error on the TCP connection, the client and the server to a last data package exchanged prior to the error using the client sequence identifiers and the server sequence identifiers and resuming a test script at a next data package after the last data package exchanged prior to the error in the sequence of data packages.Type: ApplicationFiled: February 17, 2016Publication date: August 17, 2017Inventors: Marius Pavel Nistor, Mihail Florin Constantinescu

Publication number: 20170237640Abstract: A new approach is proposed that contemplates system and method to support correlating captured network traffic going through a network appliance with its metadata for troubleshooting and debugging of the network traffic. First, network traffic in the form of data packets are captured and filtered for metadata based on user-specified parameters. A correlation is then established between the captured data packets and the metadata in a chronologically correct fashion. The metadata is then integrated and stored with the captured network packets in a correlated network traffic database in a standard storage format, which can later be retrieved for visualization, debugging and tracing of program flows and other data with respect to the network traffic through the network appliance.Type: ApplicationFiled: September 13, 2016Publication date: August 17, 2017Inventor: Matthias Stocker

Publication number: 20170237641Abstract: Techniques are disclosed for facilitating analysis of cloud activity. A cloud activity analysis agent may run within a virtual machine in a cloud computing environment to collecting information regarding computing activity within the virtual machine. The cloud activity analysis agent may include, in network flow data records, cloud activity data based on the collected information. The cloud activity analysis agent may then transmit the network flow data records to a network device for flow analysis. In some embodiments, the network flow data records are transmitted to a network flow analyzer that is configured to receive the cloud activity data and is further configured to receive network flow data from one or more flow collectors within a network of the entity. The network flow analyzer may then perform a security analysis for the entity based on the network flow data and the cloud activity data.Type: ApplicationFiled: November 15, 2016Publication date: August 17, 2017Inventors: Ryan Holeman, Al Hartmann, Josh Harriman, Josh Applebaum

Publication number: 20170237643Abstract: A method and apparatus of measuring a packet throughput in a wireless communication system are provided. When determining a reference time for estimating packet throughput, a receiver determines the time that a data burst starts or ends in order to estimate the packet throughput considering a change in the data burst of the transmitter buffer. A measurement period is defined through the determined start time and end time of the data burst, and packet throughput is measured considering the total amount of the received data burst. The throughput of packet data may be estimated by each base station based on the same standard rule, so that the measured packet throughput values may be reliable, thus allowing the operator to make use of it as a parameter for MDT.Type: ApplicationFiled: May 3, 2017Publication date: August 17, 2017Inventors: Seung June Yi, Sung Hoon Jung, Young Dae Lee, Sung Jun Park

Publication number: 20170237644Abstract: One embodiment includes a system. The system includes a receiver configured to extract a timestamp from a header of each packet of a data stream received from a network and to de-packetize the data stream to provide a stream of data blocks. The timestamp can correspond to generation of each data block associated with each respective packet of the data stream according to a global timebase. The system also includes a delay controller configured to measure a delay associated with each packet of the data stream based on the timestamp relative to the global timebase and to control converting the data stream to a corresponding analog output signal for transmission based on the measured delay.Type: ApplicationFiled: November 18, 2016Publication date: August 17, 2017Inventors: JUNIUS A.
