- Abstract
- The content delivery network (CDN) provides an environment in which a large amount of contents can betransmitted stably and quickly from suppliers to consumers. However, as high quality and large capacitycontents are produced and consumed, a more efficient content caching technique is required in CDN. It is acommon phenomenon that a small number of contents occupy the most demands in CDN. To relieve thepossible problems caused by this phenomenon, we propose a hybrid content-level viewcount forecasting methodbased on moving average and Prophet for dynamic contents caching to support an optimized dynamic contentscaching in CDN. Based on the predicted viewcount, each content is classified into either hot or cold contents foreach day to help dynamic content allocation: hot contents are allocated in a fast but expensive storage while coldcontents are allocated in a slow but inexpensive storage. Experimental results show that the proposed methodyields better hot/cold contents classification performance than benchmark methods.
