摘要： Methods and apparatus for identification and characterization of latency in a content delivery network. In one embodiment, interaction of users with content is recorded via collection of tuning records; the latency is then utilized to adjust the timing on the tuning records to account for lapses in time for sending these between entities of the network and the user devices, and for processing occurring at the devices. The latency is determined by taking into account a device specific latency component, and a network latency component. The network latency component is determined in one variant by sending a message to the device from the network requesting a response. Once the timing of the tuning records is adjusted, these tuning records may be relied upon as being accurate on a second-by-second basis. Accordingly, tuning records may be obtained and analyzed for content which lasts for a very short period of time.

摘要： In general, the disclosure describes techniques for adaptively determining one or more parameters of a service level agreement of an application. For instance, a network device may monitor round-trip times of a plurality of packets of a data flow of an application being transmitted over a link between an application server and a client device. The network device may determine an amount of retransmission of packets occurring during transmission of the plurality of packets of the data flow. The network device may predict, based at least in part on the round-trip times of the plurality of packets of the data flow and the amount of retransmission of packets occurring during transmission of the plurality of packets of the data flow, a round-trip time parameter for a service level agreement associated with the application.

摘要： Provided is a position estimation method in which a measurement signal and a response signal are transmitted and received between multiple n wireless stations respectively provided with known antennas installed at known positions different from each other and a wireless terminal station provided with a terminal antenna, RTT, which is a round-trip delay time of the transmission and reception, and RSSI, which is a strength of received radio waves of the signals, are measured, and a position of the wireless terminal station is estimated. The method includes: obtaining, as the position of the wireless terminal station, a solution of simultaneous equations of an RTT evaluation function fti for evaluating the estimate value of the position of the wireless terminal station that is estimated based on the RTT measured between the wireless terminal station and the known antenna i (i=1, 2, . . . , n), and an RSSI evaluation function fri for evaluating the estimate value of the position of the wireless terminal station that is estimated based on the RSSI, or a value obtained by searching for an estimate value so that an error evaluation function ferror obtained by combining the RTT evaluation function and the RSSI evaluation function is minimum.

摘要： A method for estimation of performance characteristics for transport control protocol includes sparsely sampling, at a middlebox, a plurality of packets from a transport control protocol (TCP) connection between a source endpoint and a destination endpoint through the middlebox. For each packet of the sampled plurality of packets, the method includes generating a time stamp when the packet is sampled and recording a sequence number and an acknowledgement number for the respective packet. The acknowledgement number is recorded when the acknowledgement number exists for the respective packet. The method also includes generating an estimated performance characteristic for the TCP connection between the source endpoint and the destination endpoint through the middlebox over the period of time based on at least two of a respective time stamp, a respective sequence number, or a respective acknowledgement number from one or more of the sampled plurality of packets.

摘要： Embodiments of the invention are directed to system structured for dynamically adapted, time latency-based, cross channel data caching for performing electronic activities. The invention is structured for selective proactive data caching based on interdependency of electronic activities and transformation of cached data for transmission through a plurality of communication channels, for reducing memory and processing burdens on data caching servers and reducing turnaround time for activity execution. Specifically, the invention is configured to detect initiation of a first technology activity event by a user at a first time, and in response, determine a second interdependent technology activity event. The invention is also structured for caching second event data for the second technology activity event prior to a second time associated with initiation of the second technology activity event at a second network device associated with a second communication channel.

摘要： Provided herein are systems and methods for providing insights or metrics in connection with provisioning applications and/or desktop sessions to end-users. Network devices (e.g., appliances, intermediary devices, gateways, proxy devices or middle-boxes) can gather insights such as network-level statistics. Additional insights (e.g., metadata and metrics) associated with virtual applications and virtual desktops can be gathered to provide administrators with comprehensive end-to-end real-time and/or historical reports of performance and end-user experience (UX) insights. Insights relating to an application or desktop session can be used to determine and/or improve the overall health of the infrastructure of the session, Citrix Virtual Apps and Desktops, the applications (e.g., remote desktop application) being delivered using the infrastructure, and/or the corresponding user experience.
