摘　　要：移动边缘计算(MEC)是6G移动通信网络中连通通信与服务、实现万物智联的支撑技术。针对MEC系统的计算时延优化,提出横向多主机架构;为优化MEC系统的传输时延及解决多主机并行计算的掉队者问题,提出多连接主从多主机架构。以上均设计了完整的信令流。针对MEC系统的性能评估,搭建了基于开源库的多主机MEC仿真平台。实验表明,提出的横向多主机MEC架构可有效提高计算时延性能;提出的多连接主从多主机MEC架构有效缓解掉队者问题,提高传输时延性能;搭建的MEC仿真平台能够有效评估多主机架构的关键性能指标。MEC(mobile edge computing)is the supporting technology for the 6G mobile communication network to connect communication and service and realize the smart connection of everything.For the computational delay optimization of the MEC system,a horizontal multi-host architecture is proposed and a complete signaling flow is designed.For the transmission delay optimization of the MEC system and the straggler problem of multi-host parallel computation,a master-slave architecture of multi-connectivity is proposed and a complete signaling flow is designed.For the evaluation of MEC system performance,a multi-host MEC simulation platform based on the open-source libraries is built.The experiments show that the horizontal multi-host MEC architecture effectively improves computational latency performance;the proposed master-slave MEC architecture of multi-connectivity effectively alleviates the straggler problem and improves transmission latency performance;the built MEC simulation platform can effectively evaluate the key performance indicators of the multi-host architecture.
