Abstract: A network management system may allocate different amounts of bandwidth to different types of data traffic. The traffic types may be distinguished by their source device address, and whether the source device is part of, or external to, a first network. Packets may also be marked by their sender with information to identify a traffic type, and the marking may be used to determine the packet's treatment. The allocations given to the various types of traffic may be dynamically modified with changing traffic demands and conditions.

Abstract: Methods and systems are disclosed for delivery of notification messaging in an IP network. A multicast gateway may receive manifest files and segments of programming content for retrieval by a client device. The multicast gateway may receive segments of a notification message and modify information in the manifest file to reference the notification message content. Upon retrieval of the manifest file by a client device, the client may access the notification message content referenced in the manifest file. The multicast gateway may replace references to programming content with references to notification message content having a corresponding content type.

Abstract: Described herein is a system and method for determining one or more data modulation profiles for one or more devices. The system and method described herein may measure signal quality, such as a modulation error ratio (MER), signal-to-noise ratio (SNR), receive power, transmit power, etc. Based on the signal quality, the system may determine one or more data modulation profile(s) (e.g., quadrature amplitude modulation (QAM) profiles) for a subcarrier, a plurality of subcarriers, a device, and/or a grouping of devices.

Abstract: According to some aspects, methods and systems may include receiving, by computing device from one or more client devices, a plurality of requests for one or more content items formatted in a first format and determining whether to multicast the one or more content items based on a data structure configured with one or more conditions associated with multicasting content. The methods and systems may also include transmitting, to the one or more client devices, the one more content items via one or more multicast streams if the requests meet a first condition of the one or more conditions. The methods and systems may also include formatting the one or more content items in a second format prior to the transmitting if network resources fail to meet a second condition of the one or more conditions.
