A processing system including at least one processor may obtain operational data from a radio access network (RAN), format the operational data into state information and reward information for a reinforcement learning agent (RLA), processing the state information and the reward information via the RLA, where the RLA comprises a plurality of sub-agents, each comprising a respective neural network, each of the neural networks encoding a respective policy for selecting at least one setting of at least one parameter of the RAN to increase a respective predicted reward in accordance with the state information, and where each neural network is updated in accordance with the reward information. The processing system may further determine settings for parameters of the RAN via the RLA, where the RLA determines the settings in accordance with selections for the settings via the plurality of sub-agents, and apply the plurality of settings to the RAN.

Radio access network control with deep reinforcement learning

A system and method () are disclosed for managing quality of service for multimedia applications. A system that incorporates teachings of the present disclosure may include, for example, a network management system (NMS) () having a controller () that manages operations of a Digital Subscriber Line Access Multiplexer (DSLAM) () interfacing to a digital subscriber line (DSL) modem () over a digital subscriber line. The controller can be programmed to detect () a signal quality violation in the digital subscriber line according to a quality policy associated with a content source, cause () the DSLAM to interleave content supplied thereto by the content source; and cause () the DSLAM to allocate to the content supplied by the content source a first portion of a data service bandwidth assigned to the digital subscriber line. Additional embodiments are disclosed.

Method and apparatus for managing quality of service for multimedia applications

A method of selecting a profile of a digital communication line includes determining a first throughput value of the digital communication line, the first throughput value associated with a first profile and determined based at least in part on a count of code violations. The method includes determining a second throughput value of the digital communication line that is associated with a second profile, the second throughput value determined based on the count of code violations. The method includes identifying a selected profile that has a greater corresponding throughput value. The first throughput value is greater than the second throughput value when the count of code violations is less than a threshold and the first throughput value is smaller than the second throughput value when the count of code violations is greater than the threshold.

Method and apparatus to select a profile of a digital communication line

A method including receiving data packets encapsulating at least part of a media stream, extracting a decoder-ready packet from the data packets, processing the decoder-ready packet; and substantially synchronously with the processing of the decoder-ready packet, generating delivery performance information for the at least part of the media stream, data from which is included in the decoder-ready packet.

In-band media performance monitoring

A method includes identifying at a gateway device of a network a plurality of devices connected to the network. The method includes monitoring network traffic at the gateway device and determining that a particular traffic flow associated with one of the plurality of devices violates a privacy constraint. The method also includes providing a risk assessment associated with the privacy constraint violation. The risk assessment is at least partially based on terms and conditions associated with a particular device of the plurality of devices.

Gated network service

A system and method is described for determining a condition of a communication line, such as the absence of a filter device on a digital subscriber line (DSL). A first signal characterized by a high upstream power is activated over the line, and a first set of parameters associated with the communication line is obtained. A second signal characterized by a low upstream power is activated, and a second set of parameters associated with the communication line is obtained. Comparison of first and second sets of parameters is indicative of a condition of the connection and presences or absence of a DSL filter on the communication line.

System and method for improving DSL performance

The application discloses a system and a method of selecting a profile of a digital subscriber line. In a particular embodiment, the method includes determining a number of code violations of the digital subscriber line; determining a first estimated data packet throughput value associated with a first profile based on the number of code violations; determining a second estimated data packet throughput value associated with a second profile based on the number of code violations; and selecting a profile to be applied to the digital subscriber line based on a comparison of the first estimated data packet throughput value and the second estimated data packet throughput value.
