Abstract
In an IPTV network, one or more caches may be provided at the network nodes for storing video content in order to reduce bandwidth requirements. Cache functions such as cache effectiveness and cacheability may be defined and optimized to determine the optimal size and location of cache memory and to determine optimal partitioning of cache memory for the unicast services of the IPTV network.
