List Interest: Packing Interests for Reduction of Router Workload in CCN 1.0

In the latest version of content-centric networking (CCN 1.0), a number of interests are issued when a large content is retrieved, and this could be a serious problem due to routers´ heavy workload. In order to solve this problem, this paper proposes a novel strategy of "grouping" multiple interests with the common information and "packing" them to a special interest called the list interest. Our list interest is designed to cooperate with the manifest of CCN 1.0. This paper demonstrates that by using the common information in the list interest, the router can search its FIB/PIT/CS for the list interest-based request with dramatically smaller complexity than the case of the standard interest-based request. Furthermore, we also give a novel TCP-like congestion control method for list interests.
