Prototype implementation of flat naming scheme ICN on Cefore as the CCN platform

In many studies on information-centric networking (ICN), the communication model is based on content names instead of network node location addresses, such as those used by IP. Content-centric networking (CCN), one of the ICN projects, facilitates the implementation of by adopting a hierarchical naming scheme for content. Hierarchical names can be seen to be more intuitively perceived by humans than IP addresses. By contrast, it is necessary for the content requester to know the full address (name) of a hierarchical name accurately, which places a large burden on the user. However, a simple naming scheme such as flat names will be easier for consumers to use. In this paper, we therefore propose a method that allows content requesters to use a flat naming scheme that involves using multiple keywords instead of hierarchical naming to generate an identifier that can be matched to content and that can generate an identifier under given conditions. For this, we choose Cefore, an experimental CCN platform, as the implementation platform because of its extensibility. The purpose of this study is to improve the practicality of CCN by investigating its performance and implementing a content retrieval method that uses multiple keywords in CCN.
