Abstract:
Lately, network usage is dominated by content distribution, and hence, Content Oriented Network (CON) has attracted attentions. CON has been actively studied at many research organizations, but it is still immature and difficult to establish clean-slate network. Therefore, our research goal is to establish a scalable and feasible architecture, which integrates the conventional IP network and a new content-oriented network framework. We use Breadcrumbs (BC) architecture as the base of integrated network but there still remains large overhead on managing and looking up forwarding table at each router. In this paper, we propose BC-Scoping on Popularity, which distributes the guidance information adaptively based on content popularity. Popularity is one of the criteria for the proposed BC-Scoping framework, which manages several BC’s distribution scopes. The proposed method enables the network to use different forwarding policies based on content popularity, and brings the benefits of smaller overhead and better system performance. Finally, we demonstrate the effectiveness of the proposed method by extensive computer simulation, including the comparison with the currently operated Content Delivery Networks (CDN) approach, using state-of-the-art popularity model newly defined.
