Aspects of the subject disclosure may include, for example, a machine-readable storage medium, including executable instructions that, when executed by a processing system including a processor, facilitate performance of operations that include assuming control of a video content transfer between a video server and a video client for HTTP traffic responsive to determining the HTTP traffic is for video content, generating a video transfer rate selection and a video transfer resolution selection for a requested video chunk of a time slot of the video content, generating an optimized manifest file for the requested video chunk, and publishing the optimized manifest file to the video client, wherein the video client request the requested video chunk from the video server based on the optimized manifest. Other embodiments are disclosed.

Video optimization proxy system and method

A system may include a first processor for storing, in a key-value column-based database, data records from data sources of a cellular network that is transformed into a single format. Customer identifiers may be used as key-values for indexing the data records in the key-value column-based database. The system may include a second processor for creating session records from the data records. Each session record may include a velocity of an endpoint device associated with a session and a number of inter-cell handoff attempts for the session. Each session record may also be labeled with a session identifier comprising a customer identifier and a timestamp. The system may further include a third processor for creating cell-level records from the session records. Each cell-level record may include a plurality of key performance indicators for a cell site of the cellular network segregated by a plurality of endpoint device types.

Cellular network hierarchical operational data storage

Methods, systems, and products simulate a topology of a communications network. Devices communicating via the communications network supply configuration and performance data. A simulated view of a topology of the communications network may then generated.

Methods, systems, and products for network topology

A method, computer-readable storage device and apparatus for addressing a problem in a network using social media are disclosed. For example, the method receives social media data, analyzes the social media data to detect a trend for a service provided by the communication network, wherein the trend indicates a problem with the service, correlates an operational parameter of the communication network providing the service to the problem with the service and adjusts the operational parameter of the communication network to address the problem.

A probing signal transmitted on a twisted pair telephone line in a DSL system is reflected and received at a DSL device. An estimate of one of a DSL data transmission signal or DSL synch symbol transmission signal is removed from the received probing signal to recover the reflected probing signal. The recovered reflected probing signal is processed to determine characteristics information of the twisted pair telephone line.

Non-invasive diagnostic transmission line testing

A Digital Subscriber Line (DSL) Management Center (DMC) coupled to a DSL network includes a data collection module that receives information regarding the DSL network from a plurality of sources. An analysis module is coupled to the data collection module to analyze the received information and issue a command for one or more of a plurality of DSL performance enhancement devices to optimize their operation. A command signal generation module is coupled to the analysis module to receive the issued command from the analysis module and generate a corresponding command signal for transmission to one or more of the DSL performance enhancement devices.

Method and apparatus for DSL performance enhancement in a DSL network

An apparatus comprises at least one vectoring engine and a cross-connect coupled to the vectoring engine. The cross-connect is to couple with each of a plurality of customer premises equipment (CPE) devices via a respective DSL loop. An interface is to receive instructions for the cross-connect to couple the vectoring engine to a nonoverlapping subset of the CPE devices via the respective DSL loops. The interface is further to receive instructions for the vectoring engine to apply vectoring to the DSL loop via which to couple one of the CPE devices to the cross-connect.

Systems, methods, and apparatuses for implementing a DSL system

A method includes receiving a packet stream at a gateway device, the gateway device coupled to a component of a content distribution system. The method also includes transmitting, from the gateway device, a wireless signal that carries data corresponding to at least a portion of the packet stream to a first device. The wireless signal is transmitted in a wireless coverage area that includes a second device configured to receive and analyze the wireless signal to produce of an assessment of the content distribution system.

Method and apparatus to analyze a wireless information delivery system

A method and apparatus in a noise cancellation system that receives a noise reference signal via a noise reference signal input port, and performs at least one of procedures a and b set forth below for reducing noise in a DSL data signal transmitted on a DSL transmission line to which the noise cancellation system is coupled: a.i.) creating a noise free representation of a DSL synchronization symbol repeatedly occurring in the transmitted DSL data signal, and a.ii.) reducing the noise in the transmitted DSL data signal based on the noise free representation of the DSL synchronization symbol and the received noise reference signal, and b.i.) analyzing at least one of the received noise reference signal and the transmitted DSL data signal to identify one or more frequency bands in which to de-emphasize noise cancellation in the transmitted DSL data signal, and b.ii.) causing the noise cancellation system to de-emphasize noise cancellation in the identified one or more frequency bands of the transmitted DSL data signal, responsive to the analysis.

DSL noise cancellation

Methods, systems, and products simulate a topology of a residential home network. The residential home network has a residential gateway and one or more devices communicating with the residential gateway. Each device may be queried by the residential gateway for configuration and performance data. A simulated view of a topology of the residential home network is then generated.
