  Abstract

By placing computing and storage resources at the network edge, edge computing inherits the advantages of cloud computing, such as providing offloading services, in addition to the additional benefits, including the reduced network delay, bandwidth use and security threat. On edge computing, the user mobility may increase the physical distance to edge server, resulting in the increased network delay. To keep the delay minimized, service migration is required, and it is important to guarantee the zero-downtime during migration. This paper introduces the implementation of a stateful, live containerized service migration for edge computing on the Docker container platform. The considered migration methods can migrate the container state by using both the layered architecture of Docker containers and the checkpoint function. Also, to trace the state changes that may happen during migration, a replay buffer is used. This paper introduces the implementation of two migration techniques that one migrates the entire running container, while the other migrates only the state changes. By experiments, it is validated that the considered migration techniques do not incur any service downtime even during when migration is in progress. In addition, it is found that the method that migrates only the state changes outperformed the other.
