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...
1. A method for determining a plurality of cache memories of a plurality of network nodes of an Internet Protocol Television (IPTV) network comprising: defining a network cost function comprising: a plurality of cache memory decision variables that represent a corresponding plurality of cache memory sizes of the plurality of network nodes;at least one cache hit rate function dependent on at least one of the cache memory decision variables; andoptimizing the network cost function to determine the plurality of cache memory decision variables and to determi...
