Abstract:

[Objective] The content naming granularity in information-centric networking (ICN) is an important influencing factor on network efficiency, especially the efficiency of routing table lookups. This work investigates the interplay between routing table lookup efficiency and content naming granularity. [Methods] Firstly, the number of network names is analyzed with respect to the content naming granularity, whereby the number of network requests and the size of routing tables are obtained under different naming methods. Then, the impact of content naming granularity on routing table lookup efficiency is further investigated. [Results] This study found that the smaller the content naming granularity, the larger the number of names and requests, and the routing table size may become larger depending on the naming method, which in turn leads to a reduction in table lookup efficiency. [Limitations] The results of this study are mainly based on the literature review, data analysis, and local testing, which means it currently lacks of support of real network testing. [Conclusions] This paper explores the impact of content naming granularity to the efficiency of ICN progressively and analyzes the main influencing factors and their interplay, which lays a theoretical foundation for further research on content naming granularity.
