Abstract

Abstract Information-centric networking (ICN) proposes a content-centric paradigm which has some attractive advantages, such as network load reduction, low dissemination latency, and energy efficiency. In this paper, based on the analytical model of ICN with receiver-driven transport protocol employing least-recently used (LRU) replacement policy, we derive expressions to compute the average content delivery time of the requests' arrival sequence of a single cache, and then we extend the expressions to a cascade of caches’ scenario. From the expressions, we know the quantitative relationship among the delivery time, cache size and bandwidth. Our results, analyzing the trade-offs between performance and resources in ICN, can be used as a guide to design ICN and to evaluation its performance.
