Service Function Chain Scheduling Method for Power Wide Coverage 5G Multi-link Converged Networks.

Currently, the extension of the end of 5G power communication network by deploying multi-link multimedia access terminals integrating multiple communication technologies has become an important development trend in power communication technology. This paper incorporates the characteristics of power communication networks and designs a converged network architecture based on 5G power converged access network and 5G-MEC, aiming to support the collaboration and flexible extension of edge network resources. Based on the consideration of constraints such as latency, computational resources, storage resources, and bandwidth resources, this paper establishes a joint optimization goal. Finally, based on the designed VNF deployment prioritization strategy that distinguishes service latency sensitivity, a VNF deployment decision algorithm based on the A3C algorithm is proposed. Simulation results show that the proposed algorithm can meet the demand for low-latency power services while avoiding network congestion, and more broadly support the “low latency, high reliability, and large bandwidth” demand for multimedia transmission, services, and network services in power networks.
