Abstract
With the explosive increase of mobile data traffic, content delivery issue on the Internet is a growing concern for both Internet service providers (ISPs) and content providers (CPs). To improve content transmission efficiency and reduce network delay, many ISP-CP cooperation schemes are designed, parts of which are trying to introduce the idea of in-network caching. However, the combination influence of edge cache and content popularity is largely ignored in the existing solutions. Therefore, we propose a novel edge cache-based ISP-CP collaboration model for content delivery services, where the two important factors are simultaneously taken into account. Then, the model is analyzed to obtain the maximal network profit from the perspective of online and offline. The simulation results show that the profit gains of the proposed solution over the existing Internet models only considering cooperation between ISPs and CPs in the heterogeneous network environments.
