Abstract
Content delivery network (CDN) has become an important means to alleviate network congestion and improve user service quality. However, with the emergence of new services such as short video and live streaming, traditional CDN has faced some challenges. In order to alleviate the lag problem of passive cache, we propose an active cache delivery scheme based on smart contract. In order to improve the utilization of storage resources in non-core locations of the network, we put forward the CDN-P2P network structure based on blockchain. Furthermore, the model predictive control (MPC) method is adopted to solve the joint optimization problem of bandwidth and delay in replica server selection. A large number of simulation experiments have been done to prove the effectiveness of our proposed scheme.
