Abstract
Content-Centric Networking (CCN), one of the most promising Future Internet architectures, is ahot research topic because of its advantages of content delivery over the Internet. Based on the Least RecentlyUsed (LRU) replacement policy in CCN, the closed-form expression of the miss-probability is first derived byconsidering the sequence of arriving requests under single cache scenario, and then extended to linear andbinary tree topologies. Consequently, the virtual round trip time (VRTT) is determined to be influenced bycache capacity and link bandwidth. The simulation results show that the proposed miss-probability modelaccords with realistic CCN network conditions, being much better than the existing model.
