摘要： Disclosed is a system and method of managing video content quality. The method includes receiving performance data at a video quality prediction system where the performance data is related to a plurality of network elements of a network path linking a video-head end with a set-top box device. The method also includes predicting, based at least partially on the performance data, a quality of video content received at the set-top box device and determining whether the predicted quality of video content is greater than or equal to a video quality threshold. In addition, the method includes identifying at least one of the plurality of network elements not satisfying a performance requirement, based on the performance data, when the predicted quality of video content is less than the video quality threshold. Further, the method includes outputting data indicating the at least one network element not satisfying the performance requirement.

摘要： A load balancer assigns a mobile registration request to a mobile communication processing server (MCPS) based on an amount of free space in a visitor location register (VLR) of the MCPS. In an embodiment, the load balancer assigns the mobile registration request to the MCPS with a probability equal to the amount of free space in the VLR divided by a total amount of free space in a plurality of VLRs of a plurality of MCPSs, the plurality of MCPSs including the MCPS.

摘要： A system for collecting data from a communications network includes customer premises equipment (“CPE”) for monitoring and storing response data. A CPE data collection module uses a Web-based service to collect information from the CPE and process the information to determine line quality and any errors that may exist on either the WAN side or the LAN side of the communications network, and further determine the root cause based on built-in business rules for trouble shooting customer service. The CPE conducts per-tone diagnostics on the WAN side of the communications network and obtains WAN side data. The CPE obtains response data from devices on the LAN side. Both WAN side data and LAN data may be transmitted substantially in real-time or stored and transmitted periodically to the CPE data collection module upon requests originated from the CPE data collection module.
