While the Internet was designed with host-oriented networking applications, recent Internet statistics show that content-oriented traffic has become more and more dominant. Even though content-oriented networking, which tries to resolve this discordance, has received increasing attention, there have been few comprehensive and quantitative studies on how to realize a content-oriented networking architecture. In this paper, the authors focus on the design alternatives of the content-oriented networking architecture and evaluate their performance: how to locate contents, how to cache contents, and how to deliver contents. There are two major infrastructure alternatives in substantiating these mechanisms: a tree and a Distributed Hash Table (DHT).
