摘要：Computer Supported Cooperation Work (CSCW) has been playing an increasingly important role in many areas of human social life. Cooperative design refers to the technique of product design based on CSCW and parallel engineering. With widespread use of CSCW, network bandwidth is becoming a bottleneck that affects user experience and service quality. Currently, global attention has been paid to the fifth-generation communication system (5G). In order to address the network bottleneck of the cooperative design system using the 5G network advantages, this paper focuses on optimizing QoE of the cooperative design system and proposes a distributed cache system for cooperative design in the 5G environment. The cache network is divided into different domains based on the characteristics of the 5G structure. Coupling between cache and cooperative design is implemented after taking the properties of the cooperative design system into account. Simulation results demonstrate the ability of the proposed system to considerably improve QoE of the cooperative design system and reduce bandwidth utilization.
