This paper addresses the performance evaluation of Content Centric Networks (CCN). Focusing on a realistic YouTube-like catalog, the authors conduct a very thorough simulation study of the main system performance, consider several ingredients such as network topology, multi-path routing, content popularity, caching decisions and replacement policies. Summarizing their main results, they gather that the impact of the topology is limited, multi-path routing may play against CCN efficiency, simple randomized policies perform almost as well as more complex ones, catalog and popularity settings plays by far the most crucial role above all.
