Research Progress for the Interest Control Protocol of Content-centric Networking

Content-centric networking (CCN) brings a new change in today's Internet communication mode, by addressing named-data instead of host locations. Another major feature is the possibility to added storage capabilities into the network. Now, the focus of this article is on the design of a receiver-driven Interest control protocol for CCN. ICP realizes a window-based Interest flow control, achieving full efficiency and fairness under proper parameters setting. In order to research ICP in-depth, in this article, the authors summary the recent research progress of it. ICP is divided into several parts: content request process, bandwidth sharing model, content request aggregation, storage sharing model. They make these process modeling, research and analysis in linear and binary tree network topology separately, and confirm the accuracy of the models and its characteristics through the numerical analysis, finally give the research trend for ICP.
