IEEE Draft Standard for an Architectural Framework for Energy Efficient Content Distribution

Abstract

This standard specifies an energy-efficient framework for video content distribution in IP over WDM networks. The framework considers delivering video content from fixed-size or variable size caches or from centralized or distributed video head-ends. To reduce the networking and caching power consumption, the framework optimizes the replacement of the caches content and the size of caches according to the content popularity changes throughout the day. Different test cases of an energy-efficient framework are presented and compared to video content delivery without caching.
