Abstract(in English) | In recent years, ICN (Information-Centric Networking) has been under the spotlight as a network that mainly focuses on transmitted and received data rather than on the hosts that transmit and receive data. Generally, the communication networks such as the ICN are required to be robust against network failures caused by attacks and disasters. One of the metrics for the robustness of conventional host-centric networks, e.g., the TCP/IP networks, is reachability between nodes in the network after network failures, whereas, the key metric for the robustness of the ICN is content availability. However, because the ICN is a more complicated network architecture compared to conventional host-centric networks, it is not easy to analyze the content availability at network failures in the ICN. In this paper, we focus on an arbitrary ICN network and derive the content availability for a given probability of node removal. Especially, we analytically obtain the average content availability over an entire network in the case that just a single path from a node to a repository, i.e., contents server, storing contents is available and that multiple paths to the repository are available, respectively. Furthermore, through several numerical evaluations, we investigate the effect of the structure of network topology as well as the pattern and scale of the network failures on the content availability in the ICN. Our findings include that, regardless of patterns of network failures, the content availability is significantly improved by caching contents at routers and using multiple paths, and that the content availability is more degraded at cluster-based node removal compared with random node removal. |
