  • Publication number: 20210266247
    Abstract: The described technology is generally directed towards reducing latency in a wireless communications network. Radio access network latency data corresponding to a measured latency impact criterion is obtained by a network device of a wireless network. Based on the radio access network latency data, latency guidance data usable by the radio network device to achieve a reduction in communication latency that is experienced by a user equipment is predicted, e.g., by a learned model. The latency guidance data can be used to facilitate a reduction in the communication latency that is experienced by a user equipment.

  • Publication number: 20210252394
    Abstract: The described technology is generally directed towards techniques to measure interaction latency. Interaction latency can be measured at a client device by measuring time intervals between user inputs and corresponding feedback, such as video frames responsive to the user inputs. Feedback can comprise communication bursts received at the client device. The communication bursts can be detected and correlated with user inputs in order to measure interaction latency. Feedback can also comprise video response features which are responsive to the user inputs. Received video frames can be analyzed to discover response features, and video frames including the response features can be correlated with user inputs in order to measure interaction latency.

  • Publication number: 20210258821
    Abstract: The described technology is generally directed towards a transport protocol for latency sensitive applications. The disclosed transport protocol is “semi-reliable” in that it allows for specification of an importance of data being transmitted, thereby allowing important data to be sent reliably, while other data can be dropped if necessary, e.g., under bad network conditions. A deadline can be specified for such other data, and if the other data cannot be sent prior to the deadline, it can be dropped. Furthermore, the disclosed transport protocol can allow for early discovery of network jitter. A client device can send regular acknowledgments which identify most recently received data packets as well as a number of “heartbeat transmissions” received at the client device. A server device can use the acknowledgments to discover and respond to jitter.
