A Feasibility Check for Utilizing Multiple Paths in Content-Centric Networking

摘要: Content-Centric Networking (CCN) re-designs the Internet architecture in a clean-slate manner. Benefits of CCN have attracted research communities to develop novel schemes to enhance a performance of original CCN architecture. In CCN, a content file consists of multiple chunks, and thus if a user retrieves content chunks from multiple paths, a content retrieval time will be substantially reduced. However, there have been less efforts on CCN transport mechanisms, especially, a multi-path data transmission. In this paper, we focus on a feasibility of retrieving chunks from multiple content holders to reduce the content retrieval time in CCN. First, we explore the design space of retrieving multiple chunks from multiple places over multiple paths. Finally we suggest an efficient method to realize the multi-path transmission concept by mitigating a side effect that can degrade content retrieving performances.
