Information-Centric Networking (ICN) provides substantial flexibility for users to obtain information. One of the most important commonalities of ICN designs is the universal caching. It is widely accepted that the in-network caching would improve performance. However, there has been no consensus on how to design an efficient caching scheme in ICN network. In this paper we propose an age-based cooperative cache scheme aiming at reducing network delay and publisher load for ICN network. We focus on light-weight collaboration mechanisms that spread popular contents to the network edge while at the same time fully utilize the storage capacity of intermediate nodes. We evaluate the effectiveness of our scheme under real traces and realistic network topology. The results indicate that our scheme achieves significant performance gains.
