    摘要: 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 optimal partitioning of cache memory for caching the unicast services of the IPTV network.

    摘要: 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.

    摘要: In an IPTV network, cache memory assigned to each DSLAM, Central Office (CO) or Intermediate Office (IO) can be determined by defining a network cost function having cache memory per DSLAM, cache memory per CO and cache memory per IO as decision variables. The network cost function can be minimized to determine the optimal cache memory size for the network. The network cost function can be subject to boundary constraints that the cache memory is between zero and a maximum cache memory size for each network node type, allowing the network cost function to be solved as a 3-ary tree.
