스마트 네트워크 경제성 분석

To cope with exploding Internet traffic, telecommunication companies are considering smart network technology. In this paper, we try to evaluate the impact of the smart network to the Internet traffic. First, ISP utilizes nodes smartly so that they can do smart caching. Second, ISP controls both routing and traffic matrix as a Telco-CDN so that they can decide more efficient traffic routing policy. Third, ISPs cooperates each other so that they efficiently control IX traffic between them as a Telco-CDNi. Finally we estimate economic value of smart network from the traffic reduction of these points.
