A Beyond 5G Edge Network for Ultra-Low Latency Services

This work aims to improve the delay performance of a Beyond 5G wireless network. The mesh network concept and the SDN concept are integrated into an edge network architecture to efficiently support multimedia communications applications. The edge network contains multiple moderate-size mesh components close to each other. The design of the components facilitates low-latency implementation and enhances the scalability of the edge network. The mesh component uses a virtual exchange mechanism internally to achieve an almost constant backhaul delay. Our design uses shortest path routing and non-rejection network traffic control mechanisms. The computer simulation results show that even in the 9-node configuration, the redundant links can make the backhaul delay at 0.4 ms-1.4 ms.
