    摘要： Cache management techniques are described for a content distribution network (CDN), for example, a video on demand (VOD) system supporting user requests and delivery of video content. A preferred cache size may be calculated for one or more cache devices in the CDN, for example, based on a maximum cache memory size, a bandwidth availability associated with the CDN, and a title dispersion calculation determined by the user requests within the CDN. After establishing the cache with a set of assets (e.g., video content), an asset replacement algorithm may be executed at one or more cache devices in the CDN. When a determination is made that a new asset should be added to a full cache, a multi-factor comparative analysis may be performed on the assets currently residing in the cache, comparing the popularity and size of assets and combinations of assets, along with other factors to determine which assets should be replaced in the cache device.

    摘要： A device, system and method are provided to dynamically manage bandwidth for audiovisual communications and content distribution. The device, system and method may include dynamic qualification of content or channels for distribution in accordance with one or more distribution models, such as a broadcast distribution model and a narrowcast distribution model (e.g., a multicast distribution model and/or a unicast distribution model). In some embodiments, the qualification may be based on demand as reflected in requests for, or access to, content from user terminals. In some embodiments, based on changes in demand for content, a requalification of the content in terms of one or more distribution models may take place.

    摘要： Systems and methods are described that relate to on-demand compression for electronic data, such as media content, through a communication pathway. The communication pathway may be a configured to multicast media content to a plurality of end-users in a service group. In certain embodiments, the service group may comprise a service group node having a quadrature amplitude modulation device. In one exemplary method, it may be determined whether the amount of media content being transmitted meets a first utilization threshold. The determination may be based on, at least in part, by measurements taken at one or more electronic devices located throughout a network or system. If the first bandwidth utilization threshold is not met, media content may be transmitted in a first format. If the first bandwidth utilization threshold is met, at least a portion of the media content may be transmitted in a first optimized delivery technique.

    摘要： The present disclosure describes a method and system for monitoring the bandwidth utilization on a high speed data network port over time. According to the method described herein, measurements of the bandwidth utilization on the port may be taken over a predetermined time interval and analyzed to determine whether the utilization measurement equals or exceeds a predetermined upper threshold. If the port exhibits high bandwidth utilization within the time interval, an alert may be set for further monitoring of the port or for port augmentation.
