Video Quality and Popularity-aware Video Caching in Content Delivery Networks
Content Delivery Network (CDN) is a popular service to accelerate object transmission by dynamically caching popular objects at cache points near users. Existing video caching schemes for CDN do not consider some important components of Quality of Experience (QoE). In this paper, we jointly consider video quality and popularity to design a new QoE metric called Video Hit Experience (VHE) and propose an efficient video caching algorithm named Hit ExpeRience-based videO caching (HERO) to improve VHE. Preliminary results show that HERO outperforms existing solutions.
