Video-On-Demand Network Design and Maintenance Using Fuzzy Optimization

Video-on-Demand (VoD) is the entertainment source which, in the future, will likely overtake regular television. Even though many companies have deployed working VoD services, to reach to the foreseen potentials, aspects of the VoD should still undergo further improvement. An important aspect of a VoD system is the underlying network in which it operates. According to the huge number of customers in this network, it should be rigorously designed to fulfill certain performance criteria. This process should be able to find optimal locations for the nodes of the network as well as to determine the content which should be cached in each one.
