Popularity-based caching for IPTV services

This study suggests to use popularity based caching for IP-based TV (IPTV) services. Our main focus is on caching the most popular video files nearby the clients, in order to reduce the IPTV service delay, increase the quality of service provided to the clients, and reduce the traffic over the Internet backbone. The proposed framework was applied on real data traces from live P2P networks. The results demonstrate a significant improvement over the Least Recently Used (LRU) cache management scheme.
