In one implementation, the system may include a memory storing instructions and a processor configured to execute the instructions. The instructions may include instructions to receive the signal, determine if at least a portion of data in the signal is missing, and when at least a portion of data is missing: process the signal using a hidden Markov model to generate an output; using the output, calculate a set of possible contents to fill a gap due to the missing data portion, with each possible content having an associated probability; based on the associated probabilities, select one of the set of possible contents; and using the selected possible content, update the signal.

Abstract: Systems and methods are provided for regulating network resources to improve data-transmission quality. In one implementation, a method includes searching one or more computer-readable memory locations for prior-session data that matches current-session data. The prior-session data may comprise information describing a prior data-transmission session and the current-session data may comprise information describing a current data-transmission session. Data describing a cause of transmission degradation may be stored in association with the prior data-transmission session. The method may also include identifying, by at least one processor, the cause of transmission degradation in the prior data-transmission session as being a cause of transmission degradation in the current data-transmission session if the prior-session data matches the current-session data. The method may also include initiating correction of the cause of transmission degradation based on the identification.

Abstract: Systems and methods are disclosed for improving transmission of media data contained in data packets in a media session established over a network. According to certain embodiments, a first server can determine that at least one media quality metric associated with the media session is below one or more pre-determined thresholds, the at least one media quality metric being indicative of a media quality. The first server can also obtain identification information associated with the media session, provide the identification information to a second server, receive, from the second server data, related to a transmission of data packets, and media data contained in the data packets. The first server can determine configurations based on the received data related to a transmission of data packets. At least one of the first and second servers can be configured based on the determined configurations to provide a pre-determined media quality.

Abstract: Systems and methods are provided for facilitating media communication sessions along a path established between endpoints over one or more networks, wherein each media communication session includes a transmission of one or more media data packets over the one or more networks. The systems and methods may include receiving a request from a first endpoint to initiate a media communication session. A system may, responsive to receiving the request, determine a configuration for the media communication session from among a set of potential configurations. The determined configuration may include a path involving one or more network elements configured to process and to transmit the media data packets, and the determination can be based on (i) a historical measurement and a real-time measurement of one or more parameters contributing to an expected quality of media communication, and (ii) a target quality of media communication.

Abstract: A hybrid communication system estimates a quality of service (QoS) for a plurality of session channels available to couple a first device on a first network with a second device on a second network. A first session channel is selected, from the plurality of session channels, that has a highest estimated QoS of all the plurality of session channels over a first time interval. The devices are instructed to establish a hybrid media session using the first session channel. During the hybrid media session the estimated QoS for the plurality of session channels is monitored. Responsive to the monitoring, a second session channel is selected, from the plurality of session channels, that has a highest estimated QoS of all the plurality of session channels over a second time interval. Responsive to the selecting, the devices are instructed establish the hybrid media session using the second session channel.

Abstract: A method and apparatus for brokering a transmission control protocol (TCP) session between two clients that are each situated behind a firewall that blocks incoming TCP session requests is described. Each of the two clients transmits a TCP session request to the other client in order to establish a TCP session between these clients. This brokering allows the two clients to establish the TCP session between the two clients.
