Summary:The Internet is becoming more and more content-oriented, where one of main components in content-oriented Internet architectures is network caching. Despite a surge of extensive use of network cashing in the current and future Internet architectures, analysis on the performance of general cache networks are still quite limited due to complex inter-plays among various components and thus analytical intractability. We study asymptotic delay performance of cache networks, in particular, focusing on the impact of heterogeneous content popularities and nodes' geometric `importances' in caching policies. Our theoretical findings provide useful engineering implications such as when and how various factors have impact on caching performance, and we provide extensive simulation results on the real Internet topology.
