Abstract
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.
