IEEE 1929.1-2025

This standard specifies a framework that supports energy-efficient video content distribution. The framework utilizes fixed-size and variable-size caches and enables cache content replacement according to the changes in the content popularity throughout the day.

The purpose of this standard is to evaluate and improve the energy efficiency of the caching and delivery of video content.

New IEEE Standard - Active. An energy-efficient framework for video content distribution in IP over WDM networks is specified in this standard. 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.
