Most CDNs pay more attention to CSP (Content Service Provider) to gain more profit from faster access rate and lower server load. However they ignore that the CDNs pay the ISPs (Internet Service Provider) for using the underlying networks based on the traffic volume generated by CDN servers. ISPs expect to save their operational cost from inter-ISP traffic and improve the QoS (Quality of Service) as well. In this paper, we propose novel decentralized content delivery architecture, ISP Manage Content Delivery Network (IMCDN). For more effectively improving the performance of IMCDN, we propose a cooperative dynamic caching strategy based on the dleft Record Counters Bloom Filter (dl-RCBF). We use the dl-RCBF to improve the remote hit rate and adopt optimistic synchronization to restrict the broadcast traffic. The experiments show that our dynamic caching strategy outperforms state-of-the-art models in hit rate for multiple cache sizes and inter-ISP traffic reduction.
