Abstract: 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.
