Enhanced time-based Interest protocol in content-centric networking (CCN)

CCN is considered as an important networking paradigm which can efficiently address traffic explosion issue of the current Internet. The time-based Interest protocol for CCN was introduced to solve an efficiency problem of early implementation of the CCN protocol in CCNx open source project. The initial version of the time-based Interest protocol, however, was able to support only real-time streaming service scenario. In this paper, we propose an enhanced mechanism of the time-based Interest protocol that supports any types of content in CCN and present experimental results demonstrating its effectiveness.
