Abstract
With the development of edge computing, the edge data center of optical interconnection has attracted extensive attention due to its storage, computing, and large bandwidth capabilities. Caching popular content in the edge data center has been proposed to reduce network load and latency. Due to the limited capability of a single edge data center, multiple edge data centers are required to cooperate to meet specific business requirements. Data in the edge computing optical network is distributed according to area deployment. Coordination between data centers will cause resource waste and delay due to the asynchronous transmission time. We designed and implemented a latency-controlled distributed content caching and data aggregation experiment in the MEC-empowered metro optical networks. The system can not only realize dynamic network configuration and service deployment but also reduce the average delay and improve the resources utilization.
