| Abstract(in English) | Internet traffic is increasing by the rapid spread of Video-on-Demand services. It is effective to cache popular contents for reducing the traffic, and its key factor is cache locations on the network. Several studies try to calculate the sub-optimal cache locations which minimize the traffic by resolving an optimization problem using heuristics such as Genetic Algorithm. However, such calculation takes a long time, and the sub-optimal locations cannot reduce much traffic since the popularities of contents continuously change, which causes mismatches in the optimal cache locations. In this research, we propose a cache control method to follow the access changes by predicting the future access trend. It generates a daily pattern of request skewness by analyzing access logs and manages the cache locations according to the generated request pattern. Our simulation results demonstrated that our predictive cache control reduces video traffic by up to 57% under a request model using realistic video popularity traces. |
