Publication number: 20220092606Abstract: A cloud services composition system allows customers to interactively create service constructs from network function virtualization resources. The network function virtualization primitives are modeled using a standard modeling language. An expert system suggests network function virtualization resources for use in the service construct, based on an expert system learning algorithm. The customer uses a graphical user interface to interconnect the resources and create the service construct. The process may involve collaboration with the network provider. The resulting construct is validated for use in a communications network.Type: ApplicationFiled: December 3, 2021Publication date: March 24, 2022Applicant: AT&T Intellectual Property I, L.P.Inventors: Rittwik Jana, Thomas Kirk, Syed Anwar Aftab, John F.

Patent number: 11252600Abstract: 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.Type: GrantFiled: February 19, 2020Date of Patent: February 15, 2022Assignee: AT&T Intellectual Property I, L.P.Inventors: Shu Shi, Rittwik Jana, Bo Han, Bo Chen

Publication number: 20210252394Abstract: 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.Type: ApplicationFiled: February 18, 2020Publication date: August 19, 2021Inventors: Michael Hwang, Sannan Tariq, Christopher Rath, Rittwik Jana, Shu Shi
